During the Metro Coronavirus Task Force briefing April 21, health officials released an updated heat map showing areas of Davidson County with the highest concentrations of residents diagnosed with coronavirus.

The map is updated weekly and represents the total number of confirmed coronavirus cases reported to the Metro Nashville Public Health Department as of April 20. It is based on ZIP codes and does not represent the exact locations of cases, according to MCTF Chairperson Dr. Alex Jahangir.

As of April 21, local health officials have announced 1,936 confirmed cases of coronavirus in Davidson County ranging in age from 2 months to 99 years old. Officials also reported two additional coronavirus-related deaths—an 85-year old man and a 63-year-old woman—bringing the total number of deaths to 22 in Davidson County.

Of the 1,936 confirmed cases, 987 residents have recovered from the virus.

The darker red color on the map indicates areas of Davidson County with higher numbers of cases.

“Those clusters you see are around certain events that have occurred, and I can’t get into the exact specific events, but think about what’s happening nationally. … You’re seeing religious events; school events; fundraisers; big family gatherings,” Jahangir said at an April 7 press briefing. “Those are consistent with what our clusters in Nashville have been thus far.”

According to Leslie Waller, an epidemiologist at the Metro Nashville Public Health Department, data collected over the last few weeks shows that confirmed cases in Nashville have shifted geographically, and most of the city’s new cases are now clustered in the southeastern part of the county.

“The communities that call this area home are numerous and diverse,” Waller said. “Our fellow Nashvillians that make up these communities also work in a number of essential service jobs, from health care to vital roles within the U.S. food system. Many of our immigrant and refugee neighbors have been putting themselves on the front lines of the [COVID-19] response, while many of us have had the advantage to work from home.”

Waller said the Metro Nashville Public Health Department will hire six to eight community outreach workers from within the city’s largest immigrant and refugee communities to share information about the virus.

While the map above represents the the total number of cases reported to the Metro Nashville Public Health Department, the map below represents 369 new cases reported for the week ending April 18.
