These cases were distributed in 14 towns, and mainly in 4 towns namely Niushan, Tuofeng, Shiliu, and Huangchuan, and the cases in the 4 towns accounted for 63.49% of the total cases. The cases occurred in the whole year, but the peak period of the disease was in April, which was related to the returned time of these patients from foreign countries. All the patients were male and aged from 20 to 55 years, and those aged from 20 to 50 years accounted for 90.70%.

CONCLUSIONS

The epidemic situation of imported malaria presents a rising trend in Donghai County in recent 10 years. To control imported malaria, the above-mentioned 4 towns with more migrant construction workers and businessmen should be treated as key areas. Meanwhile, the floating population management, disposal of the malaria epidemic spots, mosquito vector monitoring as well as health education should be strengthened.
