The Anti-Malaria Campaign (AMC) in Sri Lanka, under the Ministry of Health, has successfully controlled malaria, achieving a malaria-free certification from the World Health Organization in September 2016. Since October 2012, there have been no indigenous malaria cases, but AMC now emphasizes preventing reintroduction due to the presence of abundant vectors. To monitor imported malaria cases and vector densities, AMC utilizes a DHIS2-based health management information system that allows for the online collection and presentation of case-based, entomological, and parasitological data. This approach ensures early detection and prevention of any potential resurgence of malaria, focusing on communicable diseases.
