Malaria knowledge, attitudes and practices among migrants from malaria-endemic countries in Evrotas, Laconia, Greece, 2013

Following re-emergence of malaria in Evrotas, Laconia, in 2009-12, a malaria-control programme was implemented in 2011-12 targeting migrants from malaria-endemic countries, including house-to-house active case detection, health education and distribution of mosquito protection items. In June 2013, we surveyed migrants in Evrotas to assess their malaria knowledge, attitudes and practices to guide prevention activities. We selected participants using simple random sampling and interviewed them, using structured questionnaires. We defined mosquito protection practices (MPPs) as the use of full-length clothes/topical repellent, mosquito screens, fans or air-conditioning, and insecticides. We calculated prevalence ratios (PRs) using Poisson regression and we allowed for clustering of participants in a residence. Of 654 migrants, we invited 132 and 130 participated (all men; 120 (92%) from Pakistan). Of the 130, 56 (43%) identified fever as a malaria symptom; those who were aware of this had higher level of education (PR: 3.2; 95% confidence interval (CI): 1.2-9.0). A total of 111 (85%) used insecticide-treated bednets and 95 (73%) used more than two MPPs. Poor housing conditions (warehouses/shacks: PR: 0.8; 95% CI: 0.6-0.9), were associated with use of up to two MPPs. Despite extensive interventions in Evrotas, the level of malaria awareness among migrants remained suboptimal and poor housing conditions hindered effective mosquito protection. We recommend culturally adapted health education and improvement of housing conditions to minimise the risk of new cases and re-establishment of malaria in Greece.
