"Stay Informed: Tracking COVID, RSV, and Flu in Massachusetts Made Easy with Online Tools"

The Massachusetts Department of Public Health publishes weekly data on emergency room visits and hospitalizations for respiratory illnesses, including COVID, RSV, and the flu. The data provide insights into the levels of illness circulating in the state, with breakdowns by type of illness, age, race, sex, and county. The information is collected as part of the CDC's National Syndromic Surveillance Program and is updated every Thursday. However, data for demographic groups with fewer than 50,000 members or unknown population totals are suppressed.
