Avian influenza A (H7N9) is an influenza (flu) virus found in birds that does not normally infect humans. However, in spring of 2013, China began reporting infections with the virus in people. Most of these infections have been associated with contact with infected poultry or contaminated environments (such as poultry markets) in China. Early symptoms are consistent with seasonal flu and may include fever, cough, sore throat, muscle aches and fatigue, loss of appetite, and runny or stuffy nose. However, infection with this virus often causes severe respiratory illness and, in some cases, death.
