This week the “top 10 “ counties we are tracking for a rapidly expanding challenge from the spread of COVID-19 has shifted to include two Ohio counties, as well as counties in Colorado, California, Maryland, Michigan, California, Wisconsin, Pennsylvania and Oklahoma. 

Top 10 Counties with the Largest Magnitude of Change determined by LRI x ‘7vs7’ rate for August 10, 2020

The “top 10” counties we have identified have a population >100,000, more than 100 COVID-19 viral tests performed in the past week, an hc1 Local Risk Index™ (LRI) >7, and an acceleration factor of LRI equal to or greater than 1.5 (see this earlier post for a full explanation of LRI). 

The CV19 Lab Testing Dashboard™ powered by hc1 provides hyperlocal insights for all 3,007 counties in the United States including index factors that can indicate a rapid increase in the percent positivity [% (+)] of SARS-CoV-2 viral tests.  

For a community of 100,000, a rapid rise in the presence of positive COVID-19 viral testing is the earliest indicator that ER, hospital, ICU, ventilators, and other medical resources (clinical providers, PPE, facilities, etc.) will be heavily taxed in the next 10 to 21 days. The community that has the largest acceleration in positive tests week-over-week will see the fastest rise in the magnitude of COVID-19 cases.
