Age-acquired malaria immunity detected in Sri Lanka

A recent study investigates the immune status of individuals residing in eight villages across the Moneragala district in Sri Lanka, and the relationship with demographic changes and selected host genetic markers.

The findings indicate that there is an age-acquired immunity in this population and that there might be host genetic variants that might have links with the generation and/or maintenance of anti malarial antibodies that are maintained at high levels in this population in spite of the low incidence of malaria reported. This could be either an individual or a combined effect of these variants since some of the markers were seen to be in linkage disequilibrium.

First author was MalariaGEN Data Fellow Rajika Dewasurendra working with primary investigator Professor Nadira Karunaweera and other researchers in collaboration with MalariaGEN.
