dc.description.abstract | Malaria is a leading cause of morbidity and mortality especially in children under 5 years and
pregnant women in Zambia. Environmental factors and behavioral patterns of vectors and human
populations combine to provide favorable conditions for malaria transmission. Focal-Indoor
Residual Spraying (IRS) was first conducted in Zambia’s Luapula Province in 2014 in areas with
high burden of malaria.
A quasi experimental study design comparing incidence of malaria pre and post-IRS intervention
was used. Malaria is diagnosed by use of rapid diagnostic test or microscopically. Malaria
incidence was calculated based on extrapolated census data for health centres. We extracted
malaria morbidity data from the Health Management Information System from 2013 to 2015.
There was no physical contact with participants as only secondary data were used. Epi-Info
version 7 was used to analyze the data. Associations between variables were tested using a Chisquare
with the level of statistical significance set at desired accuracy of 5% and 95% confidence
interval.
A total of 11 of 25 (44%) health facility catchment areas conducted focal-IRS in 2014 in addition
to Insecticide Treated bed Nets (ITNs) use. Six of 11 (55%) IRS health facility catchment areas
recorded spray coverage of above 85%. Of the 11 IRS health facility catchment areas, 5 (45%)
recorded decrease in incidence of total malaria (clinical and confirmed) in 2015 compared to 2013
whilst 6 (55%) recorded increased incidence post spraying. About 5 of 14 (36%) ITN only health
facility catchment areas recorded decrease in incidence of total malaria in 2015 compared to 2013.
Only 1 of 11(9%) IRS-health facility catchment areas (Muwanguni RHC) recorded decrease in
incidence of lab-confirmed malaria while 91% recorded increase in 2015 compared to 2013.
Use of focal IRS strategy in addition to ITNs in Mansa district did not yield additional effect
compared to use of ITNs only. This strategy needs to be redesigned to ensure that questions of its
efficacy and operationalization are well understood before scale-up of the concept is enhanced.
