A detailed understanding of the human infectious reservoir is essential
for improving malaria transmission-reducing interventions. Here we report
a multi-regional assessment of population-wide malaria transmission
potential based on 1209 mosquito feeding assays in endemic areas of
Burkina Faso and Kenya. Across both sites, we identified 39 infectious
individuals. In high endemicity settings, infectious individuals were
identifiable by research-grade microscopy (92.6%; 25/27), whilst one of
three infectious individuals in the lowest endemicity setting was detected
by molecular techniques alone. The percentages of infected mosquitoes in
the different surveys ranged from 0.05 (4/7716) to 1.6% (121/7749), and
correlate positively with transmission intensity. We also estimated
exposure to malaria vectors through genetic matching of blood from 1094
wild-caught bloodfed mosquitoes with that of humans resident in the same
houses. Although adults transmitted fewer parasites to mosquitoes than
children, they received more mosquito bites, thus balancing their
contribution to the infectious reservoir. Membrane feeding
assaysThe results of the
membrane feeding experiments performed during the different infectivity
surveys are included in this dataset. In addition to data on the feeding
experiments, information on the age of study participants is
included.
