Abstract:

This paper analzyed the characteristics of malaria cases in Baoshan in 2017. Data of malaria situation in Baoshan in 2017 were collected, and analyzed by regions, sex, age, occupation, months, countries of infection source, and hospital visit time using SPSS 20.0 software. Results showed that there were 54 cases of malaria reported in 2017 in Baoshan, and all imported from other countries, consisting of 53 cases of tertian malaria and 1 falciparum malaria. Among regions, Tengchong ranked top in the number of imported cases (35, 64.8%), followed by Longyang County (9, 16.6%), Longling County (8, 14.8%), Shidian County (1, 1.8%) and Changning County (1, 1.8%). Most of the cases were males (74.1%, 40/54). The ages ranged 4-52 years, mostly concentrated between 40-44 (13, 24.1%), then between 35-39 (10, 18.5%). Most of the cases were farmers (77.8%, 42/54), then labor workers (14.8%,8/54), students (3.7%, 2/54), children (1.9%, 1/54) and drivers (1.9%, 1/54). The number of cases peaked in February (12, 22.2%), with other months having distributions of cases except December. The country sources of imported cases were Myanmar (46, 85.2%), Laos (7, 13.0%), and Republic of Guinea (1, 1.9%). The shortest interval from onset to hospital visit was 0 day (4, 7.4%), and the longest was 22 days (1, 1.8%). More cases visited hospitals on days 3 and 4 (10, 18.5% for each day). These results suggested that the monitoring and management of imported malaria should be strengthened on males, 40-44 age population, and farmers in Tengchong city.
