Epidemiology of Avian Influenza Virus in Wild Birds in Switzerland Between 2006 and 2009.

The article presents a study on the epidemiology of avian influenza virus found in wild birds in Switzerland from 2006 to 2009. Under the Swiss national avian influenza virus (AIV) surveillance scheme, researchers examined more than 2,000 samples from 41 bird species between September 2006 and December 2008. Using quantitative reverse transcriptase-polymerase chain reaction (PCR), they found that approximately 4 percent were AIV positive. They concluded that various AIV subtypes are capable of cocirculating aming the waterfowl population in wild bird habitats.
