County Covid Risk Levels

The Harvard Global Health Institute has released a new COVID Risk Level map which shows the severity of the Covid-19 outbreak at county level across the United States. The map reveals which counties have a green, yellow, orange or red risk level, based on the number of new daily cases.

On the map counties that have fewer than one daily new case of Covid-19 per 100,000 people are colored green. Counties with one to nine daily new cases are colored yellow. Counties with between 10 and 24 new cases are colored orange and counties with 25 new cases per day are shown in red. The map also allows you to view the Covid-19 risk levels at state level. This view shows that both Florida and Arizona are currently at a red risk level, both states having more than 30 new daily cases of Covid-19 per 100,000 people.

Alongside the map the Harvard Global Health Institute has released recommendations and guidance about how counties should respond to the Covid-19 outbreak risk levels. If a county is shown as red on the map then stay-at-home orders are absolutely necessary. Counties shown as orange are advised to have stay-at-home orders and test and trace programs. If a county currently has a yellow risk level then a rigorous test and trace program is advised. Counties which are shown as green should continue to monitor with testing and contact tracing.



The John Hopkins' Covid-19 Dashboard provides a global overview of the number of reported cases of Covid-19. The map reveals that there is still no sign of a flattening of the curve in the number of confirmed cases around the world.

When I first linked to this map on 23 January 2020, the map was reporting 555 total known cases and 17 deaths from Covid-19. A mere half a year later and the map reports over 10.5 million cases of Covid-19 and over half a million deaths.
