Abstract:We analyzed the epidemiological characteristics of an outbreak of anthrax in Ganquan County of Shaanxi Province and provided recommendations to put forward to control it. Epidemiological and laboratory investigation were initiated in the anthrax outbreak area of Ganquan County to trace the source of infection and identify the risk factors of the outbreak. The distribution of anthrax cases was described and the natural and social factors of epidemic outbreaks were illustrated. Results showed that the anthrax outbreak,originated from a homologous infection of B. anthracis,occurred in Ganquan County in Shaanxi Province,2015,with a total of 19 human anthrax cases reported. The genotype of outbreak-related isolates was MLVA15-31. Results indicated that the key measures to contain outbreaks in prompt and effective way were identifying epidemics timely,culling sick animals,isolating pathogen,treating patients,and disinfecting the environment.
