: [摘要] 目的 了解2017年山东省疟疾疫情特征, 为进一步制定有针对性的防治策略和措施提供科学依据。方法 收 集2017年山东省疟疾疫情资料及疟疾病例个案调查资料, 对2017年疟疾疫情流行病学特征及疟疾病例诊治情况进行统 计分析。结果 2017年山东省共报告疟疾病例209例, 均为境外输入性病例; 其中恶性疟155例, 占74.16%; 由非洲输入 205例, 占98.09%。全省16个地级市有疟疾病例报告, 其中烟台、济宁、威海、德州、青岛、泰安6市共报告154例, 占全省 疟疾病例总数的73.68%。全省17个地级市均有病例分布, 其中烟台、泰安、威海、青岛4市共有疟疾病例110例, 占全省 病例总数的56.41%。病例从发病到就诊中位时间为1 d, 7 d以上就诊者27例 (12.92%) ; 从就诊到确诊中位时间为1 d, 7 d以上确诊者22例 (10.53%)。结论 防控境外输入性疟疾仍是当前山东省疟疾防控工作的重点, 针对疟疾疫情呈现 的集中趋势应加强重点输入地区医务人员的疟疾诊治培训和高危人群健康宣教, 防范既往疟疾流行区再次出现本地病 例的风险, 确保山东省如期实现消除疟疾目标。. METHODS: The data of malaria cases of Shandong Province in 2017 were collected from the Information Management System for Infectious Diseases Report and Information Management System for Parasitic Diseases Control and Prevention. The epidemiological characteristics of malaria situation and the diagnosis and treatment of malaria cases were analyzed. RESULTS: There were 209 malaria cases reported in 2017, all of them were imported cases, and 205 cases (98.09%) were imported from African countries. Among them, 155 cases (74.16%) were falciparum malaria cases. Totally 16 cities had cases reported in 2017, and 154 cases (73.68%) were reported in 6 cities (Yantai, Jining, Weihai, Dezhou, Qingdao, and Tai'an). The malaria cases distributed in 17 cities, and there were 110 cases distributed in 4 cities, namely Yantai, Tai'an, Weihai, and Qingdao, which accounted for 56.41% of the total cases in Shandong Province. Both the median time from onset to seeing a doctor and the median time from seeing a doctor to being diagnosed were one day. Totally 12.92% of the cases went to visit a doctor 7 days later after they had symptoms and 10.53% of the cases were diagnosed 7 days later after the first visit to a doctor. CONCLUSIONS: At present, the prevention and control of the imported malaria is the focus of malaria control in Shandong Province. According to the central tendency of the malaria situation, the health education and propaganda among the high risk groups and the training on the diagnosis and treatment among medical workers should be strengthened, so as to prevent the risk of reappearance of local cases in the past malaria endemic regions, and to ensure the goal of malaria elimination been achieved on schedule.
