Abstract:To investigate the epidemiological characteristics and provide advices for developing control strategy, we analyzed all of the anthrax cases reported in Shufu of Xinjiang Uyghur Autonomous Region from 2005 to 2012 with descriptive epidemiological methods. In this analysis, a total of 137 anthrax cases were reported and the annual average incidence was 5.34/100 000. The proportion of anthrax cases in Shufu to national cases was 5.09%. All of the reported cases were cutaneous anthrax, and most of them were sporadic cases. Most anthrax cases occurred in summer and autumn, especially in July. The gender ratio of male to female was 1.36∶1, and the incidence of male was higher than female. Over 54% cases occurred in children and young adults aged <20, and the highest risk group was 10-14 years old. Almost all of the anthrax cases occurred in the race of Uyghur, while there was only one case occurred in Han. The occupation of the most anthrax cases were farmers, herdsmen and students. These results show that the incidence of anthrax in Shufu is extremely high, and it is significant that cases occurred in the age group of young. It is suggested that measures should be taken to strengthen the control of anthrax.
