The agency’s data as of March 1 shows that flu and COVID-19 test positivity rates have declined, while RSV levels remain steady. 

Three states reported “high” respiratory virus activity: Wisconsin, Ohio and New Hampshire. 

Here are three more updates: 

  1. Influenza cases are declining, with 18.9% of tests returning as positive this week. The virus remains the primary driver of respiratory illness, however, flu-related emergency department visits are expected to continue decreasing in the coming weeks, according to the CDC. 
  2. COVID-19 activity remained low, with a 3.9% test positivity rate and low emergency department visits. Wastewater surveillance suggests COVID-19 cases will remain at low to very low levels over the next two weeks, the agency said. 
  3. RSV levels remained steady, with 6.5% of tests coming back positive. ED visits and hospitalizations did not significantly change from the previous week.
