Definition
MQUSEFAN indicates whether the household uses an (electric) fan to avoid mosquitoes.
Studies have shown [URL omitted from DDI.] that using an electric fan to repel mosquitoes is somewhat effective. The breeze from an electric fan deters mosquitoes, which are slow fliers, and disperses the exhaled carbon dioxide, body heat, and body odors from humans that attract female mosquitoes to their prey.
The information in MQUSEFAN is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
