An estimated 700 million people suffer from mosquito-borne diseases worldwide. Various types of mosquito repellents are widely used to prevent mosquito bites. The objectives of this study were (1) to measure the indoor levels of particulate matter < 2.5 μm in mean aerodynamic diameter (PM2.5) and carbon monoxide (CO) during the burning of mosquito coils (MCs) and study the impact of indoor ventilation patterns; and (2) to study and compare the prevalence of respiratory ailments in homes using different types of mosquito repellents. ⋯ Burning of MCs produces indoor levels of PM2.5 and CO that are higher than those reported during the burning of biomass fuels for cooking purposes and may be associated with respiratory morbidity.
