During October 1999 to May 2000, influenza A(H3N2), A(H1N1), and B viruses were identified in the Northern Hemisphere. Influenza A(H3N2) predominated, but the number of influenza A(H1N1) viruses increased toward the end of the influenza season in the Northern Hemisphere. Since April, influenza A viruses have predominated in the Southern Hemisphere and tropical regions, but influenza B viruses also have been identified. This report summarizes influenza activity in the United States and worldwide from April 2000 through October 2000.
More than 50 million Pap tests are performed each year; however, guidelines about the frequency of testing in women with a history of normal test results are inconsistent. To determine the incidence of cervical cytologic abnormalities following a normal Pap test, data from the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) were analyzed. The findings indicated that within 3 years of a normal Pap test result, severe cytologic abnormalities were uncommon, and incidence rates were similar among women screened 1, 2, and 3 years following a normal Pap test.
