In Zambia’s Southern Province, the fight to end malaria begins with a knock on the door. An army of community health workers, dedicated volunteers chosen by their communities, are trained and equipped to test and treat their neighbors for malaria.
A positive malaria cases triggers a targeted response: the community health worker visits the home of the patient and tests everyone there. If anyone tests positive for malaria they are given treatment. Then she expands the search for the malaria parasite out to 140 meters—about the length of a football field.
Zambia is using this community surveillance approach because malaria infection tends to cluster. It’s the latest step in the country’s long fight to end malaria for good.
