A new strain of malaria resistant to artemisinin-based drugs is appearing in parts of central Burma and Vietnam, according to researchers. This follows reports last spring that drug-resistant malaria had been discovered in western Cambodia and along the Thai-Burmese border, according to US-based National Public Radio. “Showing that resistance is emerging outside of western Cambodia is a game changer,” said Dr. Rick Fairhurst, who presented a report on his latest findings the annual meeting of the American Society of Tropical Medicine and Hygiene in Atlanta on Tuesday.
