Abstract：Objective To study the epidemiological characteristics of a family cluster of human infection with avian influenza A (H7N9) virus so as to provide scientific evidence for formulating prevention and control countermeasures of human infection with the H7N9 avian influenza. Methods Field epidemiological method was used to survey the cases, close contacts and the related poultry market of a family cluster of human infection with avian influenza A (H7N9) virus in 2014. Respiratory tract specimens and environmental samples were collected, and nucleic acid of the H7N9 virus was detected by RT-PCR. Results The male patient Yang in the case A was sick on January 24th, 2014. He was diagnosed on January 30th, 2014, and his condition was critical. Yang was a butcher working in a farmer’s market, and had an exposure history of live poultry market. The patient in the case B was Yang’s daughter. The father and the daughter shared the same bed, and lived in close contact with each other. Yang’s daughter often played in the farmer’s market after school, and also had an exposure history of live poultry market. She was sick on January 30th, 2014, but her condition was not serious. Conclusions This epidemic is a family cluster of human infection with avian influenza A (H7N9) virus. The two cases may be infected by the common exposure history of the live poultry market, or there may be a possibility that the infection passes on from the father to the daughter.
