Objective: To explore the epidemic situation and epidemiological characteristics of imported malaria in Beijing City in 2017, so as to provide the evidence for developing malaria control interventions.
Methods: The data of registered malaria cases were collected and analyzed by using descriptive epidemiological methods.
Results: A total of 90 malaria cases were reported in Beijing in 2017, and all the cases were imported. The 90 cases included 74 cases of falciparum malaria (82.22%), 10 cases of vivax malaria (11.11%), 4 cases of ovale malaria (4.45%) and 2 cases of malariae malaria (2.22%), and 97.78% of the malaria patients were at ages of 19 to 61 years. Eighty-one cases (90.00%) came back from Africa and 44 cases (48.89%) suffered two or more courses of malaria. Among the 66 patients with disease onset after returning from abroad, 53 cases (80.30%) of falciparum malaria had an onset within two weeks. The patients went to the malaria-endemic areas were mainly because of working (46.34%) or business (41.46%). Eighty-nine cases used mosquito nets while living in malaria-endemic areas and 59 cases used mosquito repellents in addition.
Conclusions: The prevention and control for imported malaria is still the major target for the surveillance in Beijing City. The highly efficient surveillance system for malaria should be sustained, and the awareness of the disease among migrant workers should be enhanced.
[摘要] 目的 对2017年北京市输入性疟疾疫情和流行特征进行分析, 为制定疟疾防控措施提供参考依据。方法 收 集2017年北京市疟疾病例个案调查信息, 采用描述性流行病学方法进行统计分析。结果 2017年北京市共报告疟疾 病例90 例, 均为输入性病例, 其中恶性疟74 例 (82.22%) 、间日疟10 例 (11.11%) 、卵形疟4 例 (4.45%) 、三日疟2 例 (2.22%) ; 81例 (90.00%) 来自非洲地区, 年龄在19～61岁的病例占全部病例的97.78%, 44例 (48.89%) 有2次及以上的患 病史。66例回国后发病的病例中, 53例恶性疟病例在2周内发病 (80.30%)。发病人群出境事由主要为务工 (46.34%) 和 商务 (41.46%)。81例在境外居住时使用了蚊帐, 59例同时使用了蚊帐和蚊虫驱避剂。结论 输入性疟疾防控仍是北京 市疟疾监测工作的重点, 应持续保持高效的疟疾监测体系并提高境外务工人员的防疟意识。.
