Influenza B dominating end of flu season

Flu activity decreased for the sixth consecutive week, but rates remain above the national baseline


Flu activity has decreased for the sixth consecutive week, but rates of influenza-like illness in the outpatient setting are still above the national baseline, according to an article on the Becker's Clinical Leadership and Infection Control website.

Since early March, influenza B infections have been outpacing influenza A. The Centers for Disease Control and Prevention (CDC) agency reports 2,028 positive specimens for influenza B in the week ending March 31, compared to just 1,329 positive specimens for influenza A.

The percentage of outpatient visits for influenza-like illness was 2.4 percent for the week ending March 31, marking a 0.1 percent decline from the week prior.

This figure remains above the 2.2 percent national baseline. Additionally, 7 of 10 U.S. regions reported outpatient flu activity above region-specific baselines for the week.
