MDA In the GMS—A Big Solution for a Big Problem

Mass drug administration is helping to quell infection rates of Plasmodium falciparum in the Greater Mekong Subregion.

The parasite is to blame for nearly 63% of malaria deaths in South-East Asia. Andin the GMS, which includes Cambodia, Laos, Myanmar and Vietnam, it’s become resistant to artemisinin, the standard anti-malaria drug.

But MDA to more than 8,000 people using a combo of antimalaria drugs was found to decrease infections by 92% within 3 months. 9 months later, although some infections had returned, overall prevalence remained far below baseline levels.

MDA is not a new strategy, but it’s costly and requires substantial community engagement to deploy.
