Malaria, drug-resistant TB flourish in Myanmar

MAE SOT, Thailand, May 30 (Reuters) Simmering civil war, fake drugs and a non-existent health service in Myanmar are creating the perfect breeding ground for new, drug-resistant strains of killer diseases such as malaria and tuberculosis.

While the most immediate threat beyond Myanmar's borders is to Thailand, home to a large migrant and refugee population from the military-ruled former Burma, the long-term implications of neglect could be felt right across the globe, experts say.

At stake is a Chinese drug called artemisinin, the world's most powerful weapon against malaria, a disease that kills more than a million people a year, most of them children in sub-Saharan Africa.

The drug is most effective when used with other treatments in what are called artemisinin-based combination therapies (ACTs).

But doctors say taking ACTs incorrectly or in doses that include fake pills is one of the easiest ways of allowing the mosquito-borne parasite which causes malaria to build up immunity.

Such behaviour appears to be commonplace, Thai health officials say, in Myanmar, where health spending is only a few dollars a year for each of the country's 53 million people.

Decades of civil war against ethnic militias in eastern Myanmar have worsened the situation; A study by the Thailand-based Backpack Health Worker Team showed the region's 500,000 internal refugees have malaria infection rates as high as 12 per cent.

''So far, the malaria parasite has started to develop resistance to all drugs apart from those in the artemisinin family,'' said Francois Nosten, a French malaria expert in the northwestern Thai border town of Mae Sot.

''If this starts to happen, there is cause for real concern.'' One drug-resistant strain born in southeast Asia has already made it to Africa, Nosten said. If an artemisinin-resistant variety reached the continent, the effects would be devastating.

''If we find evidence that it has changed to become resistant to artemisinin, we would have to contain it here -- but how you would do that, I just don't know,'' said Nosten, director of the Shoklo Malaria Research Unit, a field station attached to Bangkok's Mahidol University.
