Do microsatellite markers reveal low levels of population sub-structuring of Plasmodium falciparum in southwestern Nigeria?
The absence of detectable population structure of P. falciparum in southwestern Nigeria is evident in the lack of significant differentiation between populations separated by about 200 km. This implies that a fairly uniform malaria control strategy may be effective over a wide geographic range in this highly endemic region. However, more wide-scale survey across the country will be required to inform malaria control in this large and densely populated endemic region.
SNAP serves a vital role in improving the health and well-being of households by increasing food security. Given recent legislation to reduce program size and limit program eligibility, this study underscores SNAP's continued importance in affecting households' well-being. Future research is needed to determine whether specific groups of households experience differential improvements in food security.
