Abstract

BackgroundMalaria is a major public health problem in Myanmar. Migrant populations are at high risk of contracting malaria and its control is more difficult than for settled population. Studies on malaria and migration are rare in Myanmar. This study was undertaken with the main objective of identifying socioeconomic and behavioural determinants of malaria among the migrant workers involved in gold mining, rubber and oil palm plantations.MethodsA cross-sectional analytic study was conducted using pretested interview-administered questionnaires among internal migrants (n = 406) in the malaria endemic townships of Shwegyin, Bago Region, Thanbyuzayat, Mon State and Kawthaung, Taninthayi Region from August to November, 2015. Data were collected by well-trained Basic Health Staff members in study areas, and then analysed by SPSS version 16.0 using Chi-square tests with significant level at 0.05.ResultsMajority of participants were male, Bahmar nationals, married and with primary basic education level and below. The mean duration of migratory work was 4.51 years. 43.1% of them gave definite previous history of malaria within last two years during migration. 92.9% (377/406) of them always used bed nets. Malaria determinants found were male gender (OR = 1.84, 95% CI: 1.22–2.77; P = 0.0040), habit of going out at dawn (OR = 2.36, 95% CI: 1.58–3.52; P < 0.001), usual sleeping indoors (OR = 2.14, 95% CI: 1.04–4.42; P = 0.036), torn bed net or net with large hole(s) (OR = 2.0, 95% CI: 1.21–3.3; P = 0.006), habit of not always sleeping under a bed net at night (OR = 2.02, 95% CI: 1.15–3.52; P = 0.014), alcohol drinking (OR = 2.71, 95% CI: 1.73–4.26; P < 0.001) and failure to attend malaria health talk (OR = 1.78, 95% CI: 1.2–2.65; P = 0.004).ConclusionsThe present study highlighted that it is warranted to launch an effective health education programme for malaria, and to encourage the proper use of insecticide-treated bed nets, blankets and/or mufflers and mosquito repellents to reduce the occurrence of malaria among the migrants.

Summary

Introduction

Malaria is a major public health problem in Myanmar. When travelling from low to high malaria transmission areas, they are more susceptible than the resident population. On the other hand migration from high to low transmission area will expose the previously malaria-free vectors to the infection. Migrants infected with malaria can serve as a reservoir and seed local outbreaks. This makes it difficult for countries that are linked by human mobility patterns to eliminate malaria. Malaria is a major public health problem in Myanmar adding to people economic burden and reduced productivity. If a malaria outbreak occurs in that population it is difficult to control the infection due to lack of relevant health facilities in their workplaces. The Myanmar Artemisinin Resistance Containment (MARC) Project was endorsed in 2011
