Two rounds (month 0 and month 6) of serological screening for antibodies against P. vivax in the blood of all eligible cluster inhabitants. In the clusters in the PvSeroTAT arm, participants with a positive P. vivax serology at baseline or month 6 will be treated with 7 days of primaquine 0.5mg/kg/day and a three-day course of either chloroquine (Ethiopia) or artesunate-amodiaquine (Madagascar).

Two rounds (month 0 and month 6) of serological screening for antibodies against P. vivax in the blood of a subset of eligible cluster inhabitants. Serological status will be assessed at a later stage (months later) and will not lead to treatment of sero-positive individuals.
