Influenza activity is winding down, new data from the Centers for Disease Control and Prevention indicate.
Of the 57,669 specimens tested in clinical laboratories during the week ending March 28, 9.8 percent came back positive, below the 14.3 percent rate recorded overall since Sept. 28, 2025, the CDC said in an update on April 3. Decreases were recorded in seven of 10 regions of the country, including the West and Midwest. The only regions that recorded increases were the states in or near the Northeast.
