Separately, here’s the cumulative count for the three Vienna zip codes, as of data reported 5/13/2020. I missed the 5/12/2020 update, so that data point is interpolated between 5/11 and 5/13. In the Town of Vienna ZIP (22180), we’re now up to 88 cases, with a steady 16% of those tested so far showing positive for COVID-19.
