COVID-19 Activity Level Index (CALI) Weekly Reports

The COVID-19 Weekly Activity Report provides data on COVID-19 transmission risk by six regions. This report is posted on Thursdays and uses Morbidity and Mortality Weekly Report (MMWR) dates, which are from Sunday to Saturday. MMWR dates are commonly used by the Centers for Disease Control and Prevention (CDC) to standardize weekly reporting across years.
