New Test Set to Be Game Changer in Eradicating 1 Malaria 2 新测试将颠覆的改变根除疟疾方式

NAIROBI, KENYA—

The World Health Organization estimates 3.4 billion people are at risk of malaria, with children under the age of five and pregnant women being the most vulnerable.

As World Malaria Day approaches (April 25), mortality rates are falling and a new test - well into the last stage of trials - is having positive results in Kenya.

Fatuma Chaunga, a mother of two, lives in the coastal 3 region of Likoni in Mombasa. Two years ago, most of Chaunga’s income from selling french fries and deep-fried buns was spent on hospital bills to treat malaria.

Mombasa is a malaria-prone region. More than 60 percent of the population is at risk of malaria in Kenya, where almost 36,000 children die from the disease each year.

Bed nets

A non-governmental organization called "Population Services Kenya" distributes insecticide-treated bed nets to pregnant mothers and mothers with children under one year old. Chaunga was one of the beneficiaries.

“If I do not use the net, my children will get malaria, and I will have to go to hospital or use herbal medicine," said Chaunga. "That is before I knew of MRDT. Now that I know of it, I see the importance of using the net so as to save on costs of going for treatment and use the little money I have to sustain my family.”

The MRDT that Chaunga mentions is the Malaria Rapid Diagnostic Test. In 2010, the World Health Organization recommended every suspected malaria case be confirmed by parasitological testing. PS Kenya provides the test to more than 4,000 public health facilities.

The MRDT gives results in 20 minutes and costs $1, which is affordable 4 even in rural communities.  

Dr. Dismas Osoro said it has helped reduce the abuse of antibiotics 5.

“Because earlier people were just taking anti-malarials without a test. This time we have got the importance of it. We test and dispense 6 anti-malarials, so the reckless use of anti-malarial drugs has been controlled,” said Osoro.

The World Health Organization estimates there were 198 million cases of malaria in 2013, which led to 584,000 deaths world-wide -- most of them in Africa among children under the age of five.

That makes mosquito-net distribution in malaria-endemic regions crucial.

Behavioral changes

But, according to PS Kenya regional programs coordinator 7 James Makiri, the biggest challenge is changing mindsets.

“People tend to sleep under the net during the rainy season. But during the dry season, when it is hot, they do not sleep under [the] net because it is too hot. So what we are trying to do is encourage people to sleep under [the] net every time of the year.”

For 30 years, the U.S. Centers for Disease Control and Prevention has collaborated 8 with the Kenya Medical Research Institute to fight malaria.  This collaboration 9 is developing a vaccine 10 being tested on 16,000 children.  

Professor Francis Kimani said the results have been promising 11 - but it's only part of a multi-pronged effort.

“We are coming up with newer vector control methods. We are coming up with new drugs. We are monitoring the drugs that are in use to make sure that they work well and users use them well," said Kimani. "And also, we are coming up with newer strategies to protect the host. And when you do all those things in an integrated fashion we are hoping that at the end of the day we will win against Malaria.”

Chaunga said she hopes that more and more people will embrace mosquito nets and embrace modern methods of testing for malaria - further bringing down mortality rates that WHO says are at 47 percent globally and 54 percent in Africa.
