CDC issues advisory on avian flu

The U.S. Centers for Disease Control and Prevention (CDC) recently issued a Health Alert Network (HAN) advisory regarding the highly pathogenic avian influenza A H5 virus.

The CDC issued the advisory June 2 to remind public health workers and providers that the potential of human infection exists and to make known the CDC's recommendations for patient evaluation and testing and infection control.

Between Dec. 15, 2014, and May 29, 2015, the U.S. Department of Agriculture (USDA) confirmed more than 200 instances were found of birds carrying avian influenza A H5N2, H5N8 or H5N1 viruses. The majority of these infections involved poultry, including backyard and commercial farm flocks.

USDA research has found more than 40 million birds in 20 states are either infected with or have been exposed to the virus.

No human cases of avian flu have been reported. However, the appearance of the virus in North American birds may increase the chances of that happening.
Human infections with avian viruses can occur after unprotected direct physical contact with infected birds or surfaces contaminated by avian influenza viruses, being in close proximity to infected birds or visiting a live poultry market. Human infection has not been the result of eating poultry or poultry products.
