Malaria prophylaxis amongst British residents of Lilongwe and Kasungu districts; Malawi

ABSTRACT

Questionnaires on various aspects of malaria prophylaxis were distributed to all British residents (adults and children) of Lilongwe and Kasungu districts; Malawi; and were completed and returned by 293 (response rate 89 percent ). Almost all residents used some measures to reduce mosquito contact; and 96 percent used chemoprophylaxis. Eight different chemoprophylactic regimens were used. Proguanil; alone or with chloroquine; was the most popular agent despite being associated with mouth ulcers in 25 percent of residents. Residents on this regimen had in general obtained their advice from a British source; and 75 percent considered they were adequately informed on the subject. This regimen was the most effective in preventing malaria attacks in the previous 12 months; even though over half those on proguanil alone were taking an inadequate dose. Residents on other chemoprophylactic regimens in general obtained their advice elsewhere; considered they were inadequately informed; and had a higher incidence of malaria. Whatever the regimen; 27 percent of adult residents would discontinue prophylaxis prematurely on return to the United Kingdom. Results suggest that more needs to be done to provide regular; precise and up-to-date information on malaria prophylaxis to British residents in malaria endemic areas
