Definition
SPRAYEDDK (HV253Z) indicates whether the interior walls of the household dwelling were sprayed against mosquitoes by an unknown individual or organization in the past 12 months (or some other recent reference period; see Comparability).
The information in SPRAYEDDK 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 when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
