Cambodia's untreatable strain of malaria is spreading.

Breaking news from Cambodia can be found here. CEO often finds Khmer news and translates it into English for our readers if it is interesting to expats, locals, Cambodians living abroad and anyone who wants to stay informed of the latest local and international news stories about Cambodia and our neighbors in South East Asia. There are many sources for Khmer news articles and they can all be found here in one place. Most of the media comes out of Phnom Penh, Siem Reap or Sihanoukville, but we cover national Cambodian news from all provinces.

Cambodia's untreatable strain of malaria is spreading.

Post by CEOCambodiaNews » Sat Sep 23, 2017 4:44 pm

22 September 2017
- 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 Oxford Tropical Medicine Research Unit in Bangkok said there was a real danger of malaria becoming untreatable.
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...

Lucky the anopheles mosquito is not widespread outside mountain districts.

TB can unfortunately added to the list of diseases that are developing an immunity to standard antibiotics.

Unfortunately, local clinics only give patients enough antibiotics that they can afford rather than the full course that they need. The resistance grows.

Entirely correct and then figure in the counterfeit drugs from China to create an unnecessary health problem of epidemic proportions.

This study says taking a full course of antibiotics longer than necessary actually increases the chance of resistance.

"However, the idea that stopping antibiotic treatment early encourages antibiotic resistance is not supported by evidence, while taking antibiotics for longer than necessary increases the risk of resistance."

Don't think that is right. Bacteria grow very quick. if you have too little antibiotics it doesn't kill them all and they develop resistance because the strongest survive and breed even more resistant ones

I'm not a doctor, so I'd defer to the researchers. Perhaps that's the very same problem with prolonged use - perhaps (I don't have the full text from the study) it allows the bacteria that aren't killed by the treatment in the short term begin to adapt and thus enabling further resistance.
