目的了解2005-2015年泰兴市疟疾疫情的流行病学特征,为制订符合本市的疟疾防治措施提供依据。方法收集2005-2015年泰兴市网报疟疾病例资料和流行病学个案调查报告,对数据进行描述性分析和相关分析。结果2005-2015年,全市共报告疟疾病例61例。其中本地病例4例,输入病例57例;间日疟9例,恶性疟47例,三日疟2例,卵形疟3例。输入性疟疾病例发病无明显季节性。虽然疟疾发作次数与外出时长无相关性(r=0.154,P=0.253),但与病例就诊及时性存在负相关关系(r=-0.312,P=0.014)。结论泰兴市疟疾病例以输入性为主,感染虫种多样。境外输入性疟疾仍是本市疟疾防控工作的重点。
Objective To understand the epidemiological characteristics of malaria epidemics in Taixing City from 2005 to 2015 and provide the basis for formulating malaria control measures in line with the city. Methods The data of malaria cases and epidemiological investigation from 2005 to 2015 in Taixing City were collected, and the data were analyzed descriptively and correlatedly. Results From 2005 to 2015, a total of 61 malaria cases were reported in the city. Among them, 4 were local cases and 57 were imported cases; 9 were Plasmodium vivax, 47 were Plasmodium falciparum, 2 were Plasmodium malaria and 3 were ovoid. The incidence of imported malaria cases no obvious seasonal. Although there was no correlation between the number of malaria episodes and the length of stay (r = 0.154, P = 0.253), there was a negative correlation with the timeliness of the cases (r = -0.312, P = 0.014). Conclusion The incidence of malaria cases in Taixing is mainly imported, with various insect species. Imported malaria abroad is still the focus of malaria prevention and control in this Municipality.
