目的分析2015—2016年韶关市疟疾疫情监测情况,评价疟疾防控效果,为制定巩固消除疟疾成果的防治策略和措施提供科学依据。方法收集韶关市2015—2016年“三热”病人监测、蚊媒监测及病例治疗处置资料,采用Excel2003统计软件进行数据处理。结果 2015—2016年,韶关市共监测检查“三热”病人5 033例,发现疟疾病例4例,平均阳性率0.08%,均为境外输入病例。2015—2016年的血检效率1 258.25∶1。临床初诊为疟疾和疑似疟疾病人的血检效率25.75∶1,而临床初诊为感冒和不明原因发热病人血检效率为0,工作量却是临床初诊为疟疾和疑似疟疾病人的48倍。随着疟疾发病率的下降,发热病人血检阳性率也在下降,导致血检效率的低下,如何提高血检效率是消除疟疾后阶段需要解决的关键问题。对病例正规治疗及对疫点规范处置,未出现本地感染二代病例。蚊媒监测均为中华按蚊。结论在消除疟疾后阶段,由于仍有个别输入性病例,应加强诊治及疫情处置能力的建设,简化血检对象开展有效监测,建议血检对象为流动人口中的疟疾和疑似疟疾病例。
Objective To analyze the monitoring status of malaria in Shaoguan City from 2015 to 2016, evaluate the effect of malaria control and provide a scientific basis for the prevention and control measures and measures to consolidate and eliminate malaria. Methods The data of patient monitoring, mosquito vector monitoring and case treatment in 2015-2016 in Shaoguan City were collected and processed by Excel2003 statistical software. Results From 2015 to 2016, Shaoguan City monitored a total of 5 033 cases of “three fever” patients and found 4 cases of malaria with an average positive rate of 0.08%. All of them were imported cases. Blood test results for 2015-2016 1 258.25: 1. The initial clinical examination for malaria and suspected malaria patients blood test efficiency of 25.75: 1, and clinical initial diagnosis of influenza and unexplained fever in patients with blood test efficiency of 0, workload is the first clinical diagnosis of malaria and suspected malaria patients 48 times. With the decline of the incidence of malaria, the positive rate of blood tests in febrile patients is also declining, resulting in the low efficiency of blood tests. How to improve the blood test efficiency is the key issue to be solved in the post-malaria stage. On the case of regular treatment and the standardized treatment of the epidemic, did not appear second-generation case of local infection. Mosquito vector monitoring are Anopheles sinensis. Conclusion In the post-malaria phase, as there are still some cases of imported cases, the construction of diagnosis and treatment and epidemic situation disposal should be strengthened to simplify the monitoring of blood tests. It is suggested that the target of blood test be malaria and suspected malaria in floating population.
