|Abstract: ||Background: The use of mosquito coils has gained widespread patronage in malaria-endemic countries, even
though it is not a recommended preventive measure for avoiding mosquitoes. Mosquito coils contain insecticides,
which are expected to vaporize slowly once the coil is lit, to provide protection against the mosquito. The mosquito
coil base material contains a variety of compounds capable of burning slowly to gradually release the insecticide. The
mosquito coil smoke, however, is potentially a source of indoor air pollution with implications for acute respiratory
infections (ARI) and other illnesses. The present study investigated the application of mosquito coils and associated
self-reported health issues in Ghana.
Methods: A cross-sectional study was undertaken in which questionnaires were randomly administered to 480
households across four districts in Ghana. Respondents who exclusively applied mosquito coils were grouped as test
cohort, while those who did not apply any mosquito repellency method constituted a control cohort.
Results: The test group that applied mosquito coils reported malaria incidence rate of 86.3 %. The control group that
did not apply any mosquito repellency method reported an incidence rate of malaria at 72.4 %. Chi square analysis
suggested that the observed difference was statistically significant (x2 = 4.25; p = 0.04). The number of respondents
who reported symptoms of cough from mosquito coil application (52.6 % incidence rate) was marginally greater than
their counterparts who did not apply coils (46.1 % incidence rate). It was also found that respondents with shortage of
breath, which was used as a proxy for ARI, were more likely to have applied mosquito coil.
Conclusions: The application of mosquito coils did not necessarily reduce the incidence of malaria in the study communities.
It however presented a potential respiratory risk factor, which should be further investigated by critically
examining exposure to particulate matter emissions from burning coils.|
