Dear friends and colleagues,

Super malaria spreads in South East Asia

The following article is a BBC report sent out by the South Centre on the spread of artemisinin-resistant malaria in South East Asia.

Alarm as ‘super malaria’ spreads in South East Asia

By James Gallagher
Health and science reporter, BBC News website

A recent report by the BBC shows a dangerous increase of resistance to the drug artemisinin. The World Health Organization (WHO) has recommended artemisinin-based combination therapies (ACTs) for the treatment of malaria and the spread of resistance to this drug, in the South East Asian region, is threatening the ability to provide treatment for this disease and can eventually mean that malaria becomes once again untreatable.

More worrisome, as the report explains, is that as the resistance continues to spread it can eventually move to other areas of the world such as Africa where the majority of malaria cases are found today. The report notes that about 212 million people are infected with malaria each year and that in areas of Vietnam and Cambodia failure rates of the treatment are close to 60%. Therefore, it is urgent to step up efforts to eliminate it before it is no longer possible to treat it.

The BBC report cites a letter in the Lancet Infectious Diseases journal written by scientists in the Mahidol-Oxford Tropical Medical Research Unit in Bangkok for the information in its report.

Alarm as ‘super malaria’ spreads in South East Asia

By James Gallagher
Health and science reporter, BBC News website

The rapid spread of “super malaria” in South East Asia is an alarming global threat, scientists are warning.

This dangerous form of the malaria parasite cannot be killed with the main anti-malaria drugs.

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

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

Prof Arjen Dondorp, the head of the malaria unit, told the BBC News website: “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.”

Failing treatments

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

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

The first choice treatment for malaria 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 says.

Prof 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%.

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

‘Against the clock’

There is a push to eliminate malaria in the Greater Mekong sub-region before it is too late.

Prof Dondorp added: “It’s a race against the clock – we have to eliminate it before malaria becomes untreatable again and we see a lot of deaths.

“If I’m honest, I’m quite worried.”

Michael Chew, from the Wellcome Trust medical research charity, said: “The spread of this malaria ‘superbug’ strain, resistant to the most effective drug we have, is alarming and has major implications for public health globally.

“Around 700,000 people a year die from drug-resistant infections, including malaria.

“If nothing is done, this could increase to millions of people every year by 2050.”
