Early-season rise in US flu activity continues

(CIDRAP News) – Influenza is widespread in eight US states, and some other indicators of an early flu season continue to rise, the Centers for Disease Control and Prevention (CDC) said today.

The percentage of patients' respiratory samples testing positive for flu grew to 20.7% in the week ending Dec 1, up from 15.2% the week before. And, as before, the H3N2 strain continues to dominate, which can be a sign of a more severe flu season.
