4 unusual facts about Mass drug administration


Mass drug administration

Only one project, conducted on Aneityum, a small isolated island in the Pacific, succeeded in permanently interrupting transmission using MDA as one of several malaria-control strategies.

In Southeast Asia, the medicated salt project at Pailin, on the Kampuchea-Thai border, demonstrated how drug resistance can develop when a large population of P. falciparum undergoing high transmission rates is exposed to intense drug pressure.

In 1984, MDA was added to the distribution of insecticide-impregnated bed nets (ITNs) in Sabah (Malaysia), but this failed to interrupt malaria transmission.

The only reported project with an MDA component which succeeded in permanently interrupting malaria transmission took place on the island of Aneityum, Vanuatu.
