In 2001, WNV activity was reported to CDC from 359 counties in 27 states and the District of Columbia (D.C.). This was a marked increase from 2000 when WNV activity was reported from 138 counties in 12 states and D.C. In 2001, fifteen states without any prior reports of WNV activity in animals detected infected birds, horses, or mosquitoes. Human cases of WNV disease were reported from 10 states; seven states reported human cases for the first time. Horses were the only non-human mammals reported to CDC with WNV infection in 2001. The apparent geographic limits of WNV activity in 2001 were marked by reports of dead WNV-infected birds from western Arkansas, southern Maine, and southern Florida.

The 2001-02 influenza season was mild to moderate in the United States. Influenza A (H3N2) viruses predominated, but influenza B viruses were identified more frequently toward the end of the season. Outbreaks of influenza B continue to be reported, especially among school-aged children. An influenza B strain that had not been detected in the United States since 1990, began to circulate again during the past season. Therefore, the influenza B component of the influenza vaccine will be updated for the 2002-03 season. The Advisory Committee on Immunization Practices has made important changes in the recommendations for the 2002-03 season. Vaccination of healthy children aged 6-23 months and close contact of children aged 0-23 months is encouraged because young, healthy children are at increased risk for influenza-related hospitalization. As in previous years, vaccination of children 魯 6 months who have certain high-risk medical conditions including asthma, lung or heart disease, diabetes, kidney disease, immunosuppressive diseases, or are on chronic aspirin therapy is strongly recommended.
