Objective: To understand the malaria prevalence and epidemic characteristics in Taixing City from 2005 to 2015, so as to provide the evidences for formulating the prevention and control strategy.
Methods: The malaria data of Internet reported cases as well as the reports on epidemiological survey of malaria cases in Taixing City from 2005 to 2015 were collected and analyzed with the methods of descriptive statistics and correlation analysis.
Results: A total of 61 malaria cases were reported in Taixing City from 2005 to 2015, including 4 local cases and 57 imported cases. There were 9 cases of vivax malaria, 47 cases of falciparum malaria, 2 cases of malariae malaria, and 3 cases of ovale malaria. There was no seasonality in the occurrence of imported malaria. Though there was no correlation between the times of malaria attack and the duration for going out (r = 0.154, P = 0.253), there was a negative correlation between the former and the timeliness for visiting a doctor (r = -0.312, P = 0.014).
Conclusions: The malaria cases are mainly imported ones in Taixing City, and the Plasmodium species of infection are diverse. Imported malaria overseas remains the key point for malaria control in Taixing City.
[摘要]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。.
