Multidrug-Resistant Malaria Spreading in Southeast Asia, Study Shows

Malaria is caused by Plasmodium parasites which are carried by mosquitoes and spread through their blood-sucking bites.

Strains of malaria resistant to two key anti-malarial medicines are becoming more dominant in Vietnam, Laos and northern Thailand after spreading rapidly from Cambodia, scientists warned Monday.

Using genomic surveillance to track the spread of drug-resistant malaria, the scientists found that the strain, known as KEL1/PLA1, has also evolved and picked up new genetic mutations which may make it yet more resistant to drugs.

“We discovered [it] had spread aggressively, replacing local malaria parasites, and had become the dominant strain in Vietnam, Laos and northeastern Thailand,” said Roberto Amato, who worked with a team from Britain’s Wellcome Sanger Institute and Oxford University and Thailand’s Mahidol University.
