A Suspected Person-to-person Transmission of Avian Influenza A (H7N9) Case in Ward

intRoduction Since throat swab specimens obtained from three adult Chinese patients were confirmed as an avian‐origin influenza A (H7N9) virus by local Centers for Disease Control and Prevention (CDC) in 2013,[1] many confirmed cases have been reported in Mainland of China. Although family and hospital clusters with confirmed or suspected avian H7N9 virus infection were previously reported and person‐to‐person transmission was put forward, human infection of H7N9 appears to be associated with exposure to infected live poultry or contaminated environments[2] and no clear evidence has proved that it could transmit from person to person. Here, we report a case confirmed with H7N9 after intimately contact with his H7N9 ward mate, it may be the first case infected between ward mates in a ward, so we report it here.
