Abstract：To analyze the epidemiological characteristics of human infection with avian influenza A (H7N9) and provide evidence for the prevention and control in Fujian province,the data of human infection with H7N9 virus in Fujian province from April 2013 to July 2018 were collected and the descriptive epidemiological methods were used to analyze the epidemiological feature. The results showed that a total of 108 laboratory confirmed cases were reported and 84.26% (91/108) of the cases were discovered and confirmed from pneumonia cases of unknown cause. The proportion of the cases whose onset time were between December and April the next year was 95.37% (103/108). The locations of the cases had a certain degree of regional concentration. For the cases discovered and confirmed from pneumonia cases of unknown cause, male cases accounted for 81.32% (74/91), the onset ages were 54.9±17.1 years, the cases who had a history of avian contact before onset accounted for 91.21% (83/91). The prognoses of the cases had a significant association with the ways how the cases were discovered and confirmed, but had no significant association with the time of onset, location of onset, age of onset, and the time interval of diagnosis and treatment. In conclusion, to strengthen the prevention and control of human infection of H7N9 virus in Fujian Province, the emphasis should be placed on monitoring and testing cases of unknown virus pneumonia, combined with its epidemiological characteristics.
