Tracking COVID-19 in Ohio's Counties

The New York Times is releasing a series of data files with cumulative counts of coronavirus cases in the United States, at the state and county level, over time. They are compiling this time series data from state and local governments and health departments in an attempt to provide a complete record of the ongoing outbreak. This is a map built with their data and updated (almost) daily to track progress in Ohio’s counties. The values displayed in the first heatmap are the weekly cumulative number of cases per 10,000 persons (the population estimates are from the 2014-2018 American Community Survey).

The second heatmap posts the cumulative weekly total number of cases per se.
