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 on Monday (Jul 22).
Malaria parasites resistant to key drugs have spread rapidly in South East Asia, researchers from the UK and Thailand say.
The parasites have moved from Cambodia to Laos, Thailand and Vietnam, where half of patients are not being cured by first-choice drugs.
Researchers say the findings raise the "terrifying prospect" drug-resistance could spread to Africa.
However, experts said the implications may not be as severe as first thought.
