This study evaluates an experimental serological diagnostic technique intended to identify people at high risk of having dormant malaria parasites in their liver.
800 children living in eastern Indonesia will be individually randomised to the experimental serologic test or routine care.
Children in the serological diagnosis arm will be screened for the presence of antibodies to a previously validated panel of malaria antigens optimized for sensitivity to infection during the prior 9 months. Furthermore, they also will be screened by microscopy. If positive by either test, they will be treated for that malaria infection.
Children assigned to routine care will be screened by microscopic examination and treated when they show or have history of symptoms in the last 3 days.
After initial screening and treating according to diagnostic technique, all children will be actively followed for 9 months with PCR detection every 4 weeks.
