Seasonal Influenza
Weekly Report: Influenza Summary Update - Nov. 16
During week 45 (November 4-10, 2007), a low level of influenza activity was reported in the United States. Forty-eight (2.7%) specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories were positive for influenza. The proportion of deaths attributed to pneumonia and influenza was below the epidemic threshold. The proportion of outpatient visits for influenza-like illness (ILI) and acute respiratory illness (ARI) was below national baseline levels. The Mountain and New England regions reported ILI slightly above their region-specific baselines. Three states reported local activity; 21 states and the District of Columbia reported sporadic influenza activity; and 26 states reported no influenza activity.

Avian Influenza
Study says wild birds unlikely to bring H5N1 to Americas - CIDRAP - Nov. 17
An analysis of influenza viruses collected from North American migratory birds over a 6-year period suggests that wild birds rarely carry avian flu viruses between Eurasia and North America, implying that the risk of the deadly H5N1 virus reaching the Americas by that route is probably low. The researchers say the highly pathogenic (HP) H5N1 virus has a better chance of reaching the western hemisphere via birds moved by humans than via wild birds.

Poliomyelitis Eradication
Progress Toward Poliomyelitis Eradication - India, January 2006-September 2007 - MMWR Weekly - Nov. 16
India is one of four countries where wild poliovirus (WPV) transmission has never been interrupted (the others are Afghanistan, Nigeria, and Pakistan). An outbreak of poliomyelitis cases caused by WPV type 1 (WPV1) occurred in India in 2006, primarily in the northern states of Uttar Pradesh and Bihar, where polio remains endemic. In response, the Government of India and its partners implemented additional vaccination measures based on recommendations from the India Expert Advisory Group on Polio Eradication. These measures focused predominantly on use of monovalent oral poliovirus vaccine type 1 (mOPV1),* which has higher efficacy against WPV1 than trivalent OPV (tOPV) (2,3). As a result, WPV1 cases in India decreased approximately 84% to 66 cases during January--September 2007, compared with 405 cases during the corresponding period in 2006.

Acute Respiratory Disease
Acute Respiratory Disease Associated with Adenovirus Serotype 14 - Four States, 2006-2007 - MMRW Weekly - Nov. 16
Adenovirus serotype 14 (Ad14) is a rarely reported but emerging serotype of adenovirus that can cause severe and sometimes fatal respiratory illness in patients of all ages, including healthy young adults. In May 2006, an infant in New York aged 12 days died from respiratory illness caused by Ad14. During March--June 2007, a total of 140 additional cases of confirmed Ad14 respiratory illness were identified in clusters of patients in Oregon, Washington, and Texas. Fifty-three (38%) of these patients were hospitalized, including 24 (17%) who were admitted to intensive care units (ICUs); nine (5%) patients died.
