Timeline of COVID-19 policies, cases, and deaths in your state

A look at how social distancing measures may have influenced trends in COVID-19 cases and deaths

This page was last updated on Wednesday, July 8, 2020 at 05:59 AM EDT.

This timeline shows the major infection control measures and re-openings undertaken by states after the first COVID-19 cases appeared in the United States, alongside the number of new cases and deaths in each state over the same time period.

Dots on the timeline indicate key events in each state – closings (in red), openings (in green) and other policy changes and events (in grey). Clicking on a dot will display event details below the chart. Additionally, the PREVIOUS and NEXT buttons move users through key events by day, allowing them to be viewed in chronological order. The timeline can be viewed against either new cases or new deaths. To see current cumulative case and death counts and daily counts for days with no policy events, click here.
