This study highlights the high risk of malaria exposure in African urban settings and the high heterogeneity of child exposure to the Anopheles vector between neighbourhoods in the same city.
Insecticide-treated net (ITN)
The findings confirmed the importance of assessing various factors affecting ITN usage among groups of WOCBA.
These findings suggest that the ITN use patterns observed in this study may contribute to residual transmission.
Protection against infection with ITN use varies by age group and season.
Health improvements following malaria intervention scale-up vary with endemicity, seasonality, age and time.
Insecticide-treated net ownership is critical for malaria control.
This study reveals gender disparity in ITN use, with males less likely to use ITNs particularly among ages 15--25 years.
In all the transmission settings considered, achieving a minimal level of ITN coverage is a "best buy".
With declining malaria prevalence, few individual-level characteristics were correlated with RDT positivity.
This study examined ITN ownership and underlying factors for among-household variation in use, and malaria transmission in two highland regions of western Kenya.
