Confirmed cases of COVID-19 are not evenly distributed across the U.S. Thus far, confirmed cases are mainly clustered in the Mid-Atlantic region, Florida, along the West Coast, and in large central cities throughout the middle of the U.S.
Given larger populations, it is no surprise that there are more cases in the most urban parts of the U.S., particularly those with large airport hubs, but some nonmetropolitan counties are also being affected (Figure 1). Dense populations and heavy traffic contribute in important ways to the spread of infectious diseases, including COVID-19. Physical distancing can help flatten the curve of this pandemic.
Even though there are fewer confirmed cases in rural areas right now, COVID-19 cases will soon begin increasing in rural areas. Mortality rates could be higher in rural areas given their older and sicker population composition and their more limited capacity for treating cases.
It is important to point out that these figures represent only confirmed positive tests. The actual rate of infection is much higher than shown in these maps, but access to testing in the U.S. has been abysmal. Thus far, testing rates have been particularly low in the south, which is concerning given the much higher rates of chronic health conditions in the south.
