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.

How to stop losing the fight against malaria
Jan 13,2019 - Last updated at Jan 13,2019

By Andrea Boggio and Colin Ohrt

SMITHFIELD, RHODE ISLAND/HANOI — When it comes to fighting infectious diseases, progress cannot be gauged by the availability of resources; the most important metric is the number of lives saved. By this measure, the world is on the verge of losing its battle with malaria.

After years of impressive gains, global efforts to combat the mosquito-borne illness have stalled. According to the World Health Organisation’s (WHO) most recent malaria report card, 219 million cases were reported in 2017, an increase of 3 million from the previous year. Moreover, while total annual deaths remained steady at about 435,000, declines in some regions reversed.

More alarming, the death toll could climb far higher. Data from the Consortium for Health Action, a not-for-profit group committed to eliminating incurable malaria in southeast Asia, shows a high risk of drug-resistant malaria spreading from Asia to Sub-Saharan Africa, the world’s most malaria-affected region. This is not an unprecedented concern. In the late 1950s, resistance to the anti-malarial drug chloroquine emerged in Cambodia and spread to, and throughout, Africa during the 1980s, resulting in a two- to sixfold increase in malaria-related mortality. Without urgent and coordinated interventions, it could happen again, but much faster this time.

Fortunately, there are ways to reduce this likelihood; one of the most important is to expand prevention, screening and treatment programmes for those at high risk. These include regional peacekeepers, a common if often-overlooked source of transmission of malaria parasites between Asia and Africa.

Security personnel in southeast Asia are infected at high rates with plasmodium falciparum, a parasite that causes a deadly form of the disease. In 2016, for example, research led by the US Armed Forces Research Institute of Medical Sciences in Bangkok found that 10 per cent of military personnel in northwest Cambodia were carriers. When infected Cambodian soldiers were deployed to Africa, as many may have been between 2010 and 2016, virulent strains of malaria were at risk of being spread.

From Cambodia, the malaria parasite strains may move across Myanmar to India and Bangladesh, which account for about 15 per cent of the current United Nations peacekeeping force. When Indian and Bangladeshi soldiers are stationed in Africa without malaria screening, the risk of deadly disease transmission may increase dramatically.

With pre-deployment testing, medication and widespread use of insecticide-treated uniforms, this source of malaria migration could be contained. At the moment, however, most governments and aid organisations are maintaining a status quo that largely excludes these high-risk groups. For example, we have observed that treated mosquito netting, which is an effective means of disease prevention, is not distributed in high-transmission areas, and there the use of available netting is extremely low.

In 2015, the WHO set 2020 as a deadline for halting the transmission of plasmodium falciparum in Cambodia, and called for total elimination of malaria from southeast Asia’s Greater Mekong Subregion by 2030. These ambitious targets are still achievable, but only if three key challenges are addressed.

First, a coordinated strategy is needed to target the disease in areas where transmission rates are highest, the so-called malaria islands. While many of the resources to accomplish this are already available, flexible funding and new partnerships will be essential to reduce infection rates among military, forestry and police personnel, as well as other at-risk populations.

Second, the international donors must recognise the urgency of the looming malaria pandemic. At the moment, their commitment is still insufficient. For example, The Global Fund, one of the world’s most important anti-malaria supporters, suffers from a lack of funding effectiveness. Aid recipients in the region complain that the fund’s money cannot be used for several unmet needs, including pay-for-performance incentives to motivate staff. The Global Fund justifies its approach as necessary to ensure long-term programme sustainability and host-country participation. But, faced with a public-health emergency in southeast Asia, and by extension, Africa, insisting on rigid adherence to the standard funding rules may be penny wise but pound foolish.

And, finally, we need new sources of money. A natural place to look is the United States military, for whom malaria is the number one infectious disease threat in the region. Unfortunately, the US Department of Defence has declined to offer anything more than research support, which may lead to a few extra publications, but will not help eliminate this malaria threat. Barring a change of heart, philanthropic organisations, especially the Bill & Melinda Gates Foundation, will be essential to filling the effective funding void, especially by offering financial incentives for implementing effective elimination operations.

With the right level of support and coordination, we can eliminate multidrug-resistant falciparum malaria in southeast Asia. The alternative, poor implementation, ineffective spending and misdirected research, will mean that still-evolving malaria parasites will eventually reach Africa, a deadly scenario that would turn back the clock on decades of progress.

Andrea Boggio is a professor of legal studies at Bryant University, where he researches the intersection of health and science policy. Colin Ohrt, founding director of the Consortium for Health Action, is a physician who works on eliminating drug-resistant malaria.
