Coronavirus Advances

While we are increasingly deadened by data visualizations that track the infectious spread of COVID-19 across the world and country, their logic has often been implicit. As much as tracking real-time data of deaths and “hot-spots” in the world and the nation, we trust the data viz to orient us to the infectious landscape to better gain understanding of viral spread. We seek to grasp nature of the virus’ transmission, and perhaps hope that we can better grasp its spread. We depend on these daily updates to retain a sense of agency in the chaos, but realize that they are provisional, contingent, and selective snapshots, based on testing, and exist at a time delay from the virus’ actual distribution–without much predictive value. We maddeningly realize they are dependent on testing rates and reporting, and only as good as the datasets which they re-present.

On the heels of a 5% statewide positivity rate on December 5, 2020, California was declared in a state of shut down in all its counties. It almost seems that such graphics have started to fail us, as the spread of the virus overflows the boundaries of the map and permeates its space. The choropoleth renders individual counties all but indistinct, the state drowned in widespread infections, with only a few of its less populated regions as refuges. With a flood of purple overflowing the coastal counties, the delta, the Central Valley, and the entire south of the state, was there even any point in mapping the danger of viral spread beyond a state of red alert?

Dec. 5, 2020

While mapping offers little comfort in the era of saturation of heightened risk, the color-codes alert inhabitants to the danger of increased stresses on the public health system–as much as visualization challenges to translate tools of data aggregation to visualize the pandemic., as December 6 rates grew by December 19. As we shift to map a decreasingly multi-colored state by the moderate, substantial and widespread virus, and widespread cases seem to flood the state, the map offers a security of some sort of monitoring of the pandemic’s spatial spread.

The sea of purple is like Spinal Tap going raising the volume “up to eleven,” and are a sign that we are in unexplored territory that won’t be accommodated by a simple color ramp–or, indeed, a familiar cartographic iconography among our current tools of styling space. While we are used to maps embodying meaning, what the colors of the map embody–beyond risk–is unknown. To be sure, at a time when fatalities from the coronavirus in the south of the state have skyrocketed from the middle of the month, hitting records in ways terrible to even contemplate, the field of purple is a deeply human story of loss, as a surge of hospitalizations have flooded the entire healthcare community, and stretched facilities of critical care beyond anything we have known, filling half of intensive care beds in LA County at Christmas. 2020 enough to make it hard to feel any relief in the close of a calendar year, as if that unit still held any meaning, and very grim about 2021: and while the CDC allowed that there may already be a new, more contagious strain, in the nation two days before Christmas, the arrival of the more contagious strain in California and Colorado increased alarm before New Year’s.

How to get a handle on the novel coronavirus that we have been pressing against COVID-19 dashboards since March to grasp better, and will we able to do so in 2021?

Whatever sense agency the maps impart, it is an agency that is only as good as the compromised sense of agency that we expect in an era of geolocation, on which most maps track reports of infection. Even as we face the rather grim warning that we are waiting for the arrival of a vaccine that, in the Bay Area, rates of immunization face steep obstacles of vaccine distribution due to pragmatics of freezer space required, training of extra health care workers, and monitoring and tracking the two-stage process of vaccination, we will depend for public sanity on maintaining clear communication in maps. The actual tracking of the novel coronavirus doesn’t translate that well to a state-wide model, or a choropleth, although it is the method for public health advisories that makes most sense: we do not have small-scale public health supervision in most of the nation, although they exist at some counties. The stressed Departments of Public Health in areas are without resources to manage COVID-19 outbreaks, public health compliance, or retaliations for public health violations: and the effort to create public health councils to manage compliance and violations of public health orders may be seen by some as an unneeded bureaucracy, but will give local governments resilience in dealing with an expanding epidemic, at the same time as governmental budgets are stressed, and no body of law about COVID violations exists.

Rather than map on a national or state-wide level, we can best gain a sense of how much virus is out there and how it moves through attempts of contact tracing–even if the increasing rates of infection may have gone beyond the effectiveness of contact tracing as a methodology that was not quickly adapted by a federal government the prioritized the rush to a vaccine. The basis for such a map in LA county can reveal the broad networks of contagion, often starting in small indoor gatherings across the region, and moving along networks of spatial mobility across the city and San Fernando Valley, and help embody the disease’s vectors of transmission as we watch mortality tallies on dashboards that give us little sense of agency before rising real-time tolls.


If such ESRI maps suggest a masterful data tracing and compilation project, the data is large, but the format a glorification of the hand-drawn maps of transmission that led to a better understanding of the progress of Ebola on the ground in 2014, used by rural clinics in western African countries like Liberia and Rwanda to stop the infectious disease’s transmission and monitor the progress of contagion to limit it–as well as to involve community members in the response to the virus’ deadly spread.

We may have lost an opportunity for the sort of learning experience that would be most critical to mitigate viral spread in the United States, as no similar public educational outreach was adopted–and schools, which might have provided an important network for diffusing health advisories to families, shifted predominantly to distance learning and providing meals, but we became painfully aware of the lack of a health infrastructure across America, as many openly resisted orders to mask or to remain indoors that they saw as unsubstantiated restrictions of liberty, not necessary measures.

Hand-Drawn Public Health Map of Ebola Transmission in Liberia (2014)

We are beyond contact tracing, however, and struggling with a level of contagion that has increased dramatically with far more indoor common spaces and geographic mobility. Yet the broad public health alerts that these “news maps” of viral spread offer readers omits, or perhaps ignores, the terrifying mechanics of its spread, and the indoor spaces in which we know the virus is predominantly acquired. The rise of newly infectious mutated strains of the novel coronavirus was in a sense inevitable, but the rising tension of what this means for the geographical distribution and danger of the coronavirus for our public health system is hard to map to assess its wide distribution, and we take refuge in mitigation strategies we can follow.

Why have we not been more vigilant earlier to adapt the many indoor spaces in which the virus circulates? It bears noting that the spread of virus in the state was undoubtedly intensified by over a hundred deaths and 10,000 cases of infection to spread in the density of a carceral network, which seems an archipelago incubating the spread of viral infections in the state. We only recently mapped the extent of viral spread across nineteen state prisons by late December 2020, tracked by the Los Angeles Times, but often omitted from public health alerts–

Coronavirus Cases Reported in Nineteen California Prisons, Dec. 21, 2020

–and the density of Long-Term Care centers of assisted living across the state, which were so tragically long centers of dangers of viral spread, as the New York Times and Mapbox alerted us as the extreme vulnerabilty of elder residents of nursing homes, skilled nursing facilities, retirement homes, assisted-living facilities, residential care homes who cannot live alone was noted across the world. The data that was not provided in the grey-out states interrupted the spread of infections among those often with chronic medical conditions was not surprising, epidemiologically, but terrifying in its escalation of the medical vulnerability of already compromised and vulnerable populations–and steep challenges that the virus posed.

unlike those greyed out states that fail to release data on deaths linked to COVID-19 infections, congregate on the California coast: while the New York Times depicted point-based data of the over 100,000 COVID-related deaths in nursing homes are a small but significant share of COVID deaths, exposure for populations with extraordinarily high probability of possessing multiple possibilities for co-morbidities is probably only a fraction of infections.

We strain to find metrics to map the risk-multipliers that might be integrated into our models for infectious spread. It seems telling to try to pin the new wave of infections in a state like California to increased contact after Thanksgiving–a collective failure of letting up on social distancing in place since March–as the basis for a post-Thanksgiving boom in many regions of the state, using purely the spatial metrics of geolocation that are most easily aggregated from cell phone data in the pointillist tracking of individual infections in aggregate.

New York Times/CueBiq Mobility Data

Based on cell-phone data of geolocation, a proxy for mobility or social clustering that offered a metric to track Americans’ social proximity and geogarphical mobility–including at shopping centers, oceanside walks in open spaces, and even take-out food curbside pickups, as well as outdoor meals and highway travel, few counties curbed aggregation as one might hope–although the fifty foot metric accepts the many outdoor congregations that occurred, well within the Cuebiq metric, wearing or without masks. A magenta California registered pronounced proximity, grosso modo, discounting any mindful innovative strategies in the state.

It is stunning to have a national metric for voluntary mobility, rough as it is, to measure internalization of social distancing protocols and potential danger of a post-holiday COVID-19 bump. To be sure, we are stunned by geolocation tools to aggregate but risk neglecting the deeper infrastructures that undergird transmission, from forced immobility. While geolocation tools offer opportunities for collective aggregating whose appeal has deep historical antecedents in measuring contagion and anticipating viral transmission by vectors of spatial proximity, geospatial tools create a geolocation loop in visualizations which, however “informative” perpetuate a spatiality that may not clearly overlap with the actual spatiality of viral transmission.

Even if we demanded to map what were the novel coronavirus had “hot-spots” in mid- to late March, as if processing the enormity of the scale we didn’t know how to map, aggregating data without a sense of scale.

March 26, 2020

Across the summer, it seems best to continue to map daily numbers of cases, relying on whatever CDC or hospital data from Hopkins we had, trying to aggregate the effects of the virus that was spreading across the country whose government seemed to provide little economic or medical plan, in maps that tallied the emergence of new cases, as new hotspots appeared across the land, meriting attention difficult to direct.

We are plowing infections and mortality with abandon in a steady diet of data visualizations that purport to grasp disease spread, that were once weighted predominantly to the New York area, even as they spread throughout the nation by the end of March, but remaining in the thousands, at that point, as even that low threshold was one by which we were impressed. The tracking of the local incidence of reported cases seemed to have meaning to grasp the meaning of transmission, with a pinpoint accuracy that was assuring, even if we had no way to understand the contagion or no effective strategy to contain it. But we boasted data visualizations to do so, focussing on the nation as if to contain its spread in antiquatedly national terms, for a global pandemic, not mapping networks of infection but almost struggling to process the data itself.

After all, the John Snow’s cholera maps of John Snow are the modern exemplars foregrounded in data visualization courses as game-changing images as convincingly precise pictures of infection progressing from a water pumps in London neighborhoods is often seen as a gold standard in the social efficacy of the data visualization and information display. The elevation of the pinpoint mapping of cholera mortality in relation to a water pump from which the deadly virus was transmitted in a nineteenth-century London neighborhood:

John Snow, “Cholera Deaths in Soho”

The Snow Map so successfully embodies a convincing image of contagion that it has taken on a life of its own in data vis courses, almost fetishized as a triumphant use of the plotting of data that precisely geolocated mortality statistics allow, and can indeed be transposed onto a map of the land to reveal the clustering of death rates around the infamous Broad St. pump, that created a legible vector of the transmission of diseases in the Soho neighborhood, so convincing to be touted as a monument of the data sciences.

Open-Air Water Pumps Tainted by Cholera measured in John Snow’s Map

Snow is lauded for having effectively showed that, in ways that changed scientific practices of collective observation and public health: rather than being communicated by miasmatic infections that spread to low-lying London from the Thames, mortality rates could gain a legibility in proximity to a pump that transmitted an infectious virus, often presented as a conceptual leap of Copernican proportions (which it was, when contrasted to miasma that emanated from the Thames to low-lying areas–if it anticipated a bacteriological understanding of viral transmission). The association of danger with the water procured on errands from neighborhood pumps however replaced the noxious vapors of a polluted river, as in earlier visualizations of the miasma that lifted the noxious fumes of the polluted Thames river to unfortunate low-lying urban neighborhoods, who were condemned by urban topography to be concentrations of a density of deaths of more striking proportions and scale than had been seen in the collective memory.

Snow made his argument by data visualizations to convince audiences, but he mapped with a theory of contagion. But if Snow’s maps works on how the virus is communicated in outdoor spaces–and how a single site of transmission can provide a single focus for the aggregation of mortality cases, COVID-19 is an infection that is most commonly contracted in indoor spaces, shared airspace, and the recycled unfiltered air of close quarters. And the indoor spaces where COVID-19 appears to be most often transmitted stands at odds with the contraction in outdoor common spaces of the street and service areas of water pumps, that create the clear spacial foci of Snow’s map, and the recent remapping by Leah Meisterlin that seeks to illuminate the urban spaces of the contraction of cholera in a digital visualization as a question of intersecting spatialities.

Current visualization tools compellingly cluster a clear majority of cholera deaths in proximity to a publicly accessible pump where residents drew water where viral pathogens that had colonized its handle. But we lack, at this point, a similarly convincing theory of the transmission of the novel coronavirus SARS-CoV-2.

But the logics of COVID-19’s communication is nowhere so crisp, and difficult to translate to a register that primarily privileges spatial contiguity and proximity–it is not a locally born disease, but a virus that mutates locally across a global space: a pandemic. And although contact-tracing provides a crucial means of trying to track in aggregate who was exposed to infection, we lack any similarly clear theory to metaphorically grasp the contagion–and are increasingly becoming aware of the central role of its mutation to a virus both more infection and that spreads with greater rapidity in confronting the expansive waves of infection in the United States–as if an escalated virulence grew globally in the first months of this rapidly globalized pandemic.

Our dashboards adopted the new versions of web Mercator, perhaps unhelpfully, to offer some security in relation to the nature of viral spread, which, if they served as a way of affirming its truly global scope–


–also suggested that global traffic of the virus demands its own genomic map, as the virus migrates globally, outside strictly spatial indices of global coverage, and that perhaps spatial indices were not the best, in the end, for accounting for a virus that had began to develop clear variants, if not to mutate as scarily as many feared, into a more virulent form.

And it may be that a genomic map that allow the classification of viral strains of genomic variability demand their own map: for as we learn that genomic mutation and variation closely determines and affects etiology, communication of the viral strains offers yet a clearer illustration that globalization articulates any point in terrestrial space to a global network, placing it in increased proximity to arbitrary point not visible in a simple map, but trigger its own world-wide network of markedly different infectiousness or virulence.


From December 4 2019, indeed, we could track emergent variants of the virus best outside of a spatial scale, as much as it reminded us that the very mobility of individuals across space increased the speed and stakes of viral contagion, and the difficulty to contain viral spread, in the interconnected world where viral variation recalled a flight map, set of trade routes, or a map of the flow of financial traffic or even of arms. Mutations were understood to travel worldwide, with a globalism that a spatial map might be the background, but was indeed far removed, as we moved beyond questions of contact tracing to define different sizes of genomic mutation and modifications that we could trace by the scale of mutations, not only the actual places where the virus had arrived.

Was place and space in fact less important in communicating the nature of COVID-19’s increasing virulence?

The maps of genomic variation traced not only the globalization of the virus, but its shifting character, and perhaps etiology across some thirty variants by late April, that show both the global spread of the virus, and the distinct domination of select strains at certain locations, in way that researchers later theorized the ability to “track” mutations with increasing precision. If researchers in Bologna defined six different variants of coronavirus from almost 50,000 genomes that had been mapped globally in laboratory settings to map variants of the virus whose signatures showed little more variability than strains of the flu in June, variations of signatures seemed a manner to map the speed of coronavirus that had traveled globally from by February 202 to the lungs of the late Franco Orlandi, an eighty-three year old retired truck driver from Nembro, Italy, whose family could not place China on a map when, following diagnostic protocol, attendant physicians in Bergamo asked if Orlandi had, by chance, happen to have traveled to China recently.


Despite lack of serious mutation, thankfully, the data science of genomic sequencing of the COVID-19 cases triggered by genomic mutations of SARS-CoV-2 genome of just under 30,000 nucleotides, has experienced over time over 353,000 mutation events, creating a difficult standard for transmission into equivalent hot spots: some hot spots of some mutations are far more “hot” than others, if we have tried to plot infections and mortality onto race, sex, and age, it most strikingly correlates to co-morbidities, if all co-morbidities are themselves also indictors of mortality risk. While the mutations have suggested transmission networks, have the presence of different levels of mutations also constantly altered the landscape of viral transmission?

Global Distribution of Sars-CoV-2 Variants, March 15, 2020/Los Alamos National Laboratory

It makes sense that the viral variant was tracked in Great Britain, the vanguard of genomic sequencing of the novel coronavirus as a result not only of laboratory practices but the embedded nature of research in the National Health Services and the monitoring of public health and health care. Enabled by a robust program of testing, of the some 150,000 coronavirus genomes sequenced globally, England boasts half of all genomic data. Rather than being the site of mutations, Britain was as a result the site where the first viral variant was recognized and documented, allowing Eric Volz and Neil Ferguson of Imperial College London to examined nearly 2,000 genomes of the variant they judged to be roughly 50% more transmissible than other coronavirus variants, magnifying the danger of contagious spread in ways feared to unroll on our dashboards in the coming months. As teams at the London School of Hygiene and Tropical Medicine studied the variant in late 2020 in southeast England, they found it to be 56% more transmissible than other variants, and raised fears of further mutations in ways that rendered any map we had even more unstable.

The virus SARS-CoV-2 can be expected to mutate regularly and often. While England boasts about half of all global genomic data on the virus, of the 17 million cases of SARS-CoV-2 infections in the United States, only 51,000 cases of the virus were sequenced–and the failure to prioritize viral sequencing in America has exposed the nation to vulnerabilities. And although California has sequenced 5-10,000 genomes a day of the novel coronavirus samples by December, and Houston’s Methodist Hospital have mapped 15,000 sequences as it watches for new viral variants; an American Task Force on viral variants will be rolled out early in 2021, as the discovery of viral mutations haves spread across five states in the western, eastern, and northwestern United States. While it is not clear that the viral variant or mutations would be less susceptible to polyclonal vaccines, most believe variants would emerge that would evade vaccine-induced immunity.

Recent fears of the rapidity of new strains are rooted in “significantly faster” transmission rates, however, and more easily communicable vectors of infection. If some worry the effectiveness of any vaccines could shfit in viral variants, variants of SARS-CoV-2 do not appear as yet resistant to current vaccines. Fast spreads of oncoming waves of viral transmission tied to a mutated virus of greater virulence would antiquate the promise and predictive value of a spatial map of viral incidence, mortality or infections we use in existing models–indeed, they’d demand a sophisticated double-register slider bar of temporal change able to track viral reproduction and rates of mutation–and to be viewed against the maps we have of readiness to accept the effectiveness of vaccines.

There are other constraints. The best proxy we might have for potential resistance to COVID-19 vaccination, is hinted at by the refusal of up to a sixth of the population of nations on three continents to trust vaccines’ effectiveness, independently from the effectiveness of the limited range of vaccines currently being rolled out–a bucket that makes sense given the degree to which GDP has constrained the limits of exposure to vaccines–and it must be noted that resistance to vaccines or their lack of availability is not only constrained by weatlt.

We still speak of global “hot-spots,” as if the story of collective management of the virus and its “mitigation” accommodates a familiar spatial register of geodata. Do spatial maps might track the virus which suppose the world is afflicted is the same virus of same payload as if infection rates can be black-boxed as if they had equal currency and weight as data, and told a purely spatial story of coronavirus, an epidemic that has revealed health inequalities, but also have a social context of deep social inequities that pose as blind spots?

Yet as epidemiologists began to distinguish the “ancestral virus” that arrived from Wuhan from its variations, we perhaps better grasped the nature of the pandemic’s communication, and the challenges to present the contagion in a purely cartographic register or space–mapping viral strains to reported cases of infection of varied virality, experimenting with the complex registration of different viral strains over space.

As the virus is mapped, in other words, the accuracy of our maps–and the geographic maps by which we assume spatial proximity–may be less helpful, rather than more helpful, and introduce red herrings, even if the varieties of potential visualization may seem to propose hypotheses of infectious transmission and susceptibility in the correlations they reveal: but is not a web-based map apt to suggest correlations that are perhaps less sensitive to the local variations of mutation, intensity of viral load arrival, or site of international arrival? The early “hot”-spots of Seattle WA and New York City reveal infectious density with an apparently clear demography; racial characteristics may be a proxy of urban centers and more cluttered quarters, as much as they reveal a clear correlation to collective susceptibility to a disease.

While spatial proximity in unites of counties may be less meaningful, given local populations’ mobility and the potential for super spreader events to create clusters of infection that don’t spatially translate to county lines in the manner of voter preferences, the deaths among black Americans are regionally pronounced in clusters in proximite states–Michigan, New York, and New Jersey–where they are clustered in urban areas–if the pronounced nature of southern states is terrifyingly striking as well. While the stories of increased vulnerabilities due to co-morbidities is often naturalized as an intractable if regrettably risky pre-existing conditions from high blood pressure to cardiovascular disease–some of the very categories that so clouded George Floyd’s autopsy to be truly tantamount to gaslighting as the first results of his autopsy egregiously clouded the very issue that the forensic pathology revealed the guilt of the officer who placed his knee with full weight of his knee on Floyd’s throat.

If Americans were gaslighted by the overstating of the relevance of Floyd’s history if coronary artery disease and hypertension as placing him at heightened risk of stroke in the trial whose intent was to determine guilt of intentional manslaughter by Minneapolis police officer Derek Chauvin–mis-representing the role of chronic medical conditions by treating medical conditions of black bodies as smokescreens for police violence, is the attribution of the obstacle of “pre-existing conditions” a poor excuse for a failure of adequate vigilance in providing uniform health care in America?

Is there not a steep danger of manipulating medical expertise a way of concealing the steep inequities of health care in a nation that lacks anything like a centralized public health service to guarantee uniform medical care?

The terrifyingly disproportionate representation of deaths among blacks are not due to a specific viral mutation, but might reveal a social context of disproportionate inequalities, which pop out in ways that would be less apparent in a solely spatial rubric.

One particularly terrifying is the spread of the virus in confined spaces–where it is both transmitted in spaces that offer few opportunities for social distancing, and among individuals kept indoors, often without access to new or filtered air supply. The soaring rates of COVID-19 infections and deaths in Long-Term Care Facilities in the United States will benefit from deeper drilling down into datasets removed from familiar state or county buckets, but is telling–and an important underlying foundation of the maps of rates of infection alone, as they constitute both a uniquely sensitive demographic, and a unique setting for the virus to grow, and a number that has tragically and overwhelmingly grown over time in the southern and western states in the summer months. As almost nine hundred more long-term care facilities reported outbreaks than in the previous week, rising mortality rates appear to be climbing in ways only a vaccine seems able to come to terms.

Even in a hovermap that provides greater information on local deaths, it is unclear if we want to rely on the familiar choropleth to parse risk–even if reporting standards may vary, and some states don’t report data that is open or transparent. In a society where the small number of Americans that live in long-term care facilities–at this point, less than 1%, the large share they bear of almost two fifths of deaths for COVID-19–38% at of the start of 2021–is terrifying. If due to their pre-existing risk, presents a population that is not only in dire need of vaccination and emergency control, the spatial clustering of deaths may reflect the stresses on which such facilities are subject, and the delayed reaction of the notorious increased spread of disease in the midwestern states where social distancing norms were not imposed to help staunch the spread of the virus, as booms of COVID hit North and South Dakota followed into the fall–boosted by the lack of social distancing at the Stugis, SD motorcycle rally, whose attraction of half a million was poised to be a major source of spreading up to 266,000 individual infections throughout the Midwest–bringing 460,000 maskless motorcycle riders over ten days in close contact together in bars, sidewalks, and garages, in a multiple super-spreader at public health costs of $12.2 billion, in large part due to how Gov. Kristi Noem openly eschewed mask-wearing mandates all summer long, since the July 4 rally–calling stay-at-home orders “fiction” more than science.

Long-term exposure to breath without social distancing in indoor spaces hurt other industries in meat-packing, and especially in poultry line processing–cleaning, evisceration, deboning, processing and packing–as waivers for distancing were granted to increase line production to increase producing drumsticks, thighs, breasts, and chicken wings that created ten-fold health risks for plant workers. Would it not be better to offer butchers stipends to provide online courses in carcass butchering?

The secrecy that employers have long maintained on line plants have created little ability to control dangers in poultry plants, but suggests only some of the workplace protections needed to slow viral spread–even when wearing gloves, as masks proved difficult to negotiate in workspaces that privileged speed over safety.

The need to balance the clustering of specific indoor spaces where the virus is transmitted–prisons; poultry processing plants; long term care facilities–might well be balanced with a finer grain set of hex maps to help map the specific danger of more contagious viral strains–not relying on a single public health dashboard, but getting used to juggling several as we start to learn to be able to find a map adequate to frame and embody the novel coronavirus’ spread. Might a similar clustering of infections, as much as deaths, and indeed the intensity of infection and perhaps the tracking of transmission reveal, at a finer grain, the possible results of viral mutations? While the presence of virus, more than mutations, is on the front burner of America, we risk using maps of diminished relevance by a point-based sense of viral incidence, and the blurred relevance spatial indices, might best be revealed in the hexmaps of based on data from the COVID racial data trackers. Such maps, perhaps on a smaller-scale format for tracking communicability in clusters, might be more meaningful than a uniformly continuous space.

One might create useful hex-based animations, analogously, tracking distributions of positive testing for COVID-19 that complete database of a National Health Service allows, able, we have seen recently, of discriminating the rise of local strains and mutations, to assess and map distinct rates of local transmission.

The hex maps rather brilliantly blur clusters of positive cases rather than relying on discrete dots, suggesting waves of contagion that may be tracked, but, in the national map that animates the distribution of positive Covid-19 Tests in England an efflorescence of contagion across board collectives in strikingly organic ways.

National Distribution of Positive Covid-19 Tests in England

New cases diagnosed make sense plotted on national hex maps to track positive testing rates against viral strains, vaccine acceptance, and other “hot spots” of concern–like rest homes or prisons–to offer a closer grain analysis of how such collective populations fare against statewide or regional averages; the “state” may be an even more arbitrary category of parsing than a “county,” but offers a sense of regional textures of concern.

Even if we abandon such an organic time-lapse animation, the hex map offers a tool for averaging cases, perhaps deserving to be broken down, if data permitted, by county more than by state, a rather lumpy aggregate even if smoothed to groups of 100.000, and indeed demands more analytic demographic parsing. But it removes us, in helpful ways, from a notion of geolocation of viral outbreaks that is perhaps not helpful, and depends on accurate reporting and uniform testing rates, and assumes complete tallies of infections. Is it more helpful to disaggregate our spatial models, even if we are habituated to an ideal of precise geolocation?

COVID-19 Average New Cases per Day-Hexmap/Evan Lu/Tableau Hex Map

Increasingly, with the dominance of different strains growing in subsequent waves by the fall and late summer, the mutation of the virus seemed to have boosted its contagiousness, in ways we had earlier failed to map, and that the variability of mortality rates or infection rates alone fail to communicate.

Perhaps by considering maps more as hypotheses to draw on space, as much as exact records of viral transmission, we could approach a more helpful communicative role of maps, or restore a communicative function all too often necessitated and important in our current tastes of shock and awe, if only as we risk being too shocked and too awed to comprehend immensity that doubly dwarfs our sense of space and individual experience.

Prisons, and other sites if incarceration, offer a parallel if counter-example, of indoor spaces housing a demographic with probably fewer potential co-morbidities. The Associated Press has tracked in a humanized bar graph, tracking by dots of ten cases of infection, broken down per week in the United States, that review the cumulative cases of infection–but if we would like to view this spatially, it is also the case that, if possible, a global register of prisoners infected with coronavirus would be valuable to assemble, and to compare to sites of migrant detention, which have become a third hot-bed of viral communication, that deserve to jump out in our response to viral spread, in ways that the state-wide parameter of a choropleth smothers.

Yet is ta focus on the human hosts of the virus at this point even the best way to map the virus—rather than the spaces that it occupies, a there is so much virus out there that an appetite for maps has grown, in hopes that they will give us some purchase on a virus whose terrible effects almost overwhelm the mind? The maps are hard to process anything, so removed are they from the loss of life, and so unclear a sense do they seem to offer of the transmission of viral loads, whose vectors of transmission we are still retrospectively map to grasp what errors of recognition, algorithms of reporting, and possible delays of diagnostic testing defined how we were able to plot cases of contagion that might assure a better guideline for managing the novel virus. We wince with frustration at the variations between government records of COVID testing rates that only escalated dramatically in March 2020, as the first cases of infections by the novel coronavirus were reported in the United States, and the failed public notifications of the scale of testing that was officially recognized by the government as grounds to respond to a pandemic they imagined the nation was impervious.

But the true map, underlying human testing and transmission, that may mean the most for the future, in the end, is the identification of potential hot spots sites for outbreaks of infectious zoonotic disease: attempts to model variations between their reported cases of emergence (a) and by weighting the global distribution by the reporting of potential emergence, factoring out reporting bias and weighted by global population, were constructed as monitory maps back in 2017. As much as reveal probability future emergent outbreaks of zoonotic disease, the map reminds us of the importance of transparency and increased security in reporting outbreaks, and assessing global threats of emerging zoonotic diseases like the novel coronavirus–EID’s–by creating clearer global protocols to respond to and track their diagnosis in the most meaningful maps.
