The rapid spread of "super malaria" in Southeast Asia is an alarming global threat, scientists have warned.

This dangerous form of the parasite cannot be killed with existing anti-drugs, the BBC reported on Saturday.

It emerged in Cambodia but has since spread through parts of Thailand, Laos and has arrived in southern Vietnam.

The team at the Oxford Tropical Medicine Research Unit in Bangkok said there was a real danger of becoming untreatable.

Proffesor Arjen Dondorp, the head of the unit, told the BBC: "We think it is a serious threat.

"It is alarming that this strain is spreading so quickly through the whole region and we fear it can spread further (and eventually) jump to Africa."

In a letter, published in The Lancet Infectious Diseases, the researchers detailed the "recent sinister development" that has seen resistance to the drug artemisinin emerge.

About 212 million people are infected with each year. It is caused by a parasite that is spread by blood-sucking mosquitoes and is a major killer of children, the BBC reported.

The first choice treatment for is artemisinin in combination with piperaquine.

But as artemisinin has become less effective, the parasite has now evolved to resist piperaquine too.

There have now been "alarming rates of failure", the letter said.

Dondorp said the treatment was failing around a third of the time in Vietnam while in some regions of Cambodia the failure rate was closer to 60 per cent.

Resistance to the drugs would be catastrophic in Africa, where 92 per cent of all cases happen.
