Maps tracking the progress of the U.S.’s COVID-19 vaccination campaign at the CDC’s COVID Data Tracker (now) include an interactive county-level map showing first and second doses among 12+, 18+ and 65+ populations and a map of vaccine equity (above): a bivariate choropleth map showing the relationship between vaccination coverage and social vulnerability (housing, vehicle access, general poverty).
This interactive map compares U.S. COVID vaccination rates with active cases at the county level. Created by McKinsey and Company’s COVID Response Center, it’s a bivariate choropleth map that shows two variables at once. (If this confuses you, the legend helps.) It’s a good way to see where low vaccination rates correlate with lots of COVID cases (red on this map), or high vaccination rates with few cases (teal); the map lets you explore other variables as well.

The Centers for Disease Control and Prevention released data and maps showing the estimated rate of COVID-19 vaccine hesitancy in the U.S. on a county-by-county basis. The data is based on a question in the Census Bureau’s Household Pulse Survey that asked respondents whether they’d get a vaccine for COVID-19 once it was available to them.

Last week Google announced “over 100 AI-powered improvements to Google Maps” would be coming this year; these include bringing Live View indoors, a new air quality map layer, eco-friendly routing, and support for curbside pickup in business listings.
Meanwhile, Apple Maps is now displaying airport COVID-19-related health measures based on data from Airports Council International: press release. [AppleInsider, MacRumors]
On February 21 the U.S. reached a grim milestone: half a million deaths due to COVID-19. This NBC News interactive map visualizes the scale of this tragedy with a county-by-county dot map of those deaths, and offers narrative detail in certain places. [Maps Mania]
The New York Times maps the distribution of COVID-19 cases in Los Angeles. “County officials recently estimated that one in three of Los Angeles County’s roughly 10 million people have been infected with Covid-19 since the beginning of the pandemic. But even amid an uncontrolled outbreak, some Angelenos have faced higher risk than others. County data shows that Pacoima, a predominantly Latino neighborhood that has one of the highest case rates in the nation, has roughly five times the rate of Covid-19 cases as much richer and whiter Santa Monica.”
According to a survey, more than a quarter of the U.S. population would not get a COVID-19 vaccine if it was available to them. This number is not evenly distributed: this map from MIT Technology Review, presented as a map showing whether your neighbours want to get vaccinated, reveals the regional pockets of vaccine hesitancy (see above). (What the actual hell, Louisiana?)
Alejandro Polanco’s latest Kickstarter project is the Pandemic Atlas. The idea, he says, “is to gather the most relevant information about the pandemics and major epidemics that have hit humanity throughout history to create an atlas in the visual style of my Minimal Geography project.” In 130 pages, the Pandemic Atlas explores major epidemics throughout history, and includes general chapters on heath subjects. The project’s inception actually predates the COVID-19 pandemic; it was initally inspired by the 100th anniversary of the 1918 pandemic, but at the time there was not much interest in the topic. Fast forward today, when an atlas about historical pandemics is just a little too topical.
The Pandemic Atlas Kickstarter runs through 24 February (it’s already met its goal). €20 gets you a digital copy of the atlas, €60 adds the hardcover.
Kenneth Field explores (and dismantles) the mythology around John Snow, the discovery that cholera was spread by water, the role of the famous cholera map and whether it revolutionized disease mapping. Depending on what you know about the subject—if, for example, you got what you know from an episode of Map Men—what you know is more myth than history: the map came after the Broad Street outbreak, it was not by any means the first example of disease mapping, and John Snow wasn’t the map’s cartographer. Field:
The mythology surrounding his work, the 1854 epidemic, and specifically the role of the map are a fine story, but much of it is retold according to the version many seem happy to believe rather than what really happened. But the real story is just as interesting. There are plenty of excellent longer form discussions of the story in which you may be interested. In particular, Kari McLeod’s excellent article that goes into detail about the various myths, and an article by Tom Koch and Kenneth Denike also goes into detail about the true order of events.
The thing that seems to worry authorities most about COVID-19 is its potential to overwhelm hospitals, at which point the mortality rate really begins to shoot up. In March, the University of Minnesota’s Carlson School of Management released the COVID-19 Hospitalization Tracking Project, which maps, on a county-by-county, basis, the percentage of hospital and ICU beds occupied by COVID-19 patients.

Rather than applying restrictions across their entire jurisdictions, several authorities are designating zones to target measures to prevent the spread of novel coronavirus where the spread is at its greatest. Maps can quickly indicate not only where COVID is at its worst, but also where restrictions have been put into place. Two examples: New York City (above left) and the province of Quebec (above right). New York’s map is interactive and has an address search, whereas Quebec’s map is spectacularly ungranular: diagonal lines show that a region has more strict restrictions in some areas but not others, but does not map those areas (which are indicated in text).
Ottawa Public Health has partnered with the Ottawa Neighbourhood Study to produce this interactive map of COVID-19 rates in Ottawa’s neighbourhoods. Both the map and its underlying data are subject to many caveats: the differences between rural and urban zones, between where people live and where people are tested, and other factors affecting testing and susceptibility. Most notably, the map is updated only monthly, so the current map (screenshotted above) does not take into account the rapid increase in positive cases over the past week or two as Ottawa entered the second wave.

The New York Times maps COVID-19 cases at U.S. colleges and universities. The map and searchable database are based on their survey of more than 1,600 post-secondary institutions; the survey “has revealed at least 88,000 cases and at least 60 deaths since the pandemic began. Most of those deaths were reported in the spring and involved college employees, not students. More than 150 colleges have reported at least 100 cases over the course of the pandemic, including dozens that have seen spikes in recent weeks as dorms have reopened and classes have started.”
