Update: Influenza Activity -- United States

Influenza activity in the United States continues to decline (Figure 3). Almost all influenza virus isolates this season have been type B (76.1%) or type A(H3N2) (23.8%). However, from February 17 to February 24, type A(H1N1) viruses were isolated from three persons, aged 3, 4, and 31 years, with influenza-like illness who lived in the same neighborhood in west Houston, Texas. Despite continued surveillance, no further type A(H1N1) isolates have been identified in Houston. In Hawaii, one type A(H1N1) virus isolate was reported this season.

In Birmingham, Alabama, recent laboratory results have shown that an outbreak of influenza among college students reportedly caused by influenza type A(H3N2) virus (1) was primarily associated with type B influenza virus. Reported by Influenza Research Center, Baylor College of Medicine, Houston, Texas; State and Territorial Epidemiologists; State Laboratory Directors; Statistical Svcs Br, Div of Surveillance and Epidemiologic Studies, Epidemiology Program Office, WHO Collaborating Center for Influenza, Influenza Br, Div of Viral Diseases, Center for Infectious Diseases, CDC.
