ABSTRACT

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.
