目的为了科学地预防和控制狂犬病,对保山市狂犬病疫情进行分析并对2014年保山市狂犬病进行风险评估。方法调查云南省保山市狂犬病疫情资料、流行病学资料、狂犬病疫苗使用情况、犬存栏数和相关的狂犬病防治措施。结果 2004年1月1日至2014年9月10日,保山市共发生人间狂犬病13例,其中2014年施甸县5例,这5例狂犬病潜伏期41~167 d,中位数113 d;地理分布由南向北主要分布在旧城乡至水长乡的公路两旁的乡村。保山市合计犬伤人率为2.75/10万,其中施甸县为19.51/10万,龙陵县为1.19/10万,昌宁县为0.38/10万,腾冲县为0.33/10万和隆阳区为0.29/10万。以犬伤人率最低的隆阳区为参考,施甸县为隆阳区的61.49倍(χ^2=169.990,P〈0.05),其他县与隆阳区比较差异无统计学意义。施甸县、龙陵县和隆阳区3县(区)兽用狂犬病疫苗免疫率比较,差异有统计学意义(χ^2=32 415.930,P〈0.05),施甸县的兽用狂犬病疫苗免疫率高。结论近期在保山市发生人间狂犬病数≥5例可能性风险较低;3~4例可能性风险中等;1~2例可能性风险较高。发生的地区为施甸、龙陵县和隆阳区3县(区)风险很高;发生在昌宁县和腾冲县2县风险中等。
Objective To understand the incidence and public health risk of rabies in Baoshan, Yunnan province, and provide evidence for the prevention and control of rabies. Methods The analyses were conducted on the data of rabies incidence, epidemiological characteristics, vaccination and prevention/control. Results From 2004 to 10 September, 2014, a total of 13 rabies cases were reported in Baoshan, in which 5 were reported in Shidian in 2014. The incubation period of the 5 cases ranged from 41 days to 167 days with the median of 113 days. The cases were mainly distributed in the villages on the both sides of the road from Jiucheng (south) to Suichang (north). The overall incidence of dog bite was 2.75/lakh, and it was 19.51/lakh in Shidian, 1.19/lakh in Longling, 0. 38/lakh in Changning, 0. 33/lakh in Tenchong and 0. 29/lakh in Longyang. The incidence of dog bite in Shidian was 61.49 times higher than that in Longyang(x^2 = 169. 990, P 〈 0.05), compared with other counties the differences were not statistical significant. There were significant differences in dog vaccination rate among Shidian, Longling and Longyong(x^2 = 32 415. 930, P 〈 0. 05 ). The rate was highest in Shidian. Conclusion The risk of 〉 5 cases occurring was low, the risk of 3 - 4 cases occurring was moderate and the risk of 1 -2 cases occurring was high in Baoshan, The risk in Shidian, Longling and Longyang was high and the risk in Changning and Tenchong was moderate.
