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.

However, experts said the implications may not be as severe as first thought.
