Objective:
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.
Methods:
The malaria data were collected and analyzed by using Microsoft Excel 2010 in Tengchong City from 2010 to 2015.
Results:
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.
Conclusions:
Imported malaria is severe in Tengchong City, and there is a great challenge to malaria elimination.
