[Abstract]:Objective to investigate the distribution of H7N9 avian influenza virus in Shaoxing city from 2013 to 2016, and to provide reference for prevention and control. Methods the samples of different types of external environment in different wading places were collected, and real-time fluorescence quantitative PCR was used to detect the samples. The monitoring data were analyzed by Excel2003 and SPSS19.0 software. Results from 2013 to 2016, a total of 3 295 samples were collected from Shaoxing city, 247 positive samples were detected, the positive rate was 7.50%. In different places, the positive rate of live poultry market was 12.09 in urban and rural areas, the positive rate of other places was 8.56, the positive rate of poultry slaughtering and processing factory was 2.22, the positive rate of poultry scale farm was 1.18, the positive rate of poultry was 0.38, the positive rate of wild migratory bird habitat was not detected. Among the different types of specimens, the positive rate of cleaning poultry sewage specimens was 12.84, the positive rate of wiping specimens on the surface of slaughtered or placed poultry table was 9.65, the positive rate of wiping specimens was 7.50 on the surface of cage utensils, and the positive rate of other specimens was 7.50. The positive rate of pharynx and visceral smear was 7.24%, the positive rate of fecal specimen was 5.59 and the positive rate of poultry drinking water was 5.56. Conclusion H7N9 avian influenza virus is prevalent in the environment outside Shaoxing, and the positive rate of H7N9 avian influenza virus is the highest in urban and rural live poultry market. It is a high risk place for human infection with H7N9 avian influenza virus.
