Abstract

To analyze the malaria epidemiological characteristics in Tengchong City from 2010 to 2015, so as to provide the evidence for adjusting and formulating measures in the elimination stage. The malaria data were collected and analyzed by using Microsoft Excel 2010 in Tengchong City from 2010 to 2015. There were 1 408 malaria cases reported in Tengchong City from 2010 to 2015, including 1 091 cases of Plasmodium vivax infection, 256 cases of P. falciparum infection, 5 cases of P. malariae infection, 1 case of Plasmodium ovale infection, 1 case of mixed infections, and 54 unclassified cases. Totally 1 390 imported cases were recorded and 98.06% of them (1 363/1 390) were imported from Myanmar. Most of the patients (n = 908) were aged from 21 to 40 years, and the male to female ratio was 11.03∶1. The highest-risk populations were farmers and migrant workers. The most cases were observed in April and June, and at that time, most of the floating workers returned. Imported malaria is severe in Tengchong City, and there is a great challenge to malaria elimination.
