In Ta Sanh, the Village MalariaWorkers or VMWs play a crucialrole in the early detection andtreatment of the killer falciparummalaria. In September 2010, theContainment Project partnered theUSAID-funded University ResearchCo., LLC (URC) to train these VMWsto prepare blood slides on DaysZero and 3, from those who testedpositive for falciparum malaria.

In the Access database, a script interfaces with Google Earth and maps out the locations of the Day 3 positives based on the village code.
