On Thailand's border with Myanmar, also known as Burma, a malaria research and treatment center is increasing efforts to kill, or eliminate, a drug-resistant form of the parasite before it spreads abroad. VOA correspondent Steve Sandford reports from Thailand.
A health center near a busy border crossing in Thailand has had great success over the last 20 years in reducing the effect of malaria.
Cases of the disease have greatly decreased. But doctors like Cindy Chu remain worried.
"We used to see a lot of malaria at the Wangpha clinic but now with efforts of elimination and active surveillance and even the setting up of malaria posts on the other side of the border, the malaria rates have really gone down. So we don't see as much malaria as we used to. On the other hand, the malaria that we do see is more complicated. And because of artemisinin resistance, the cases we see here require additional therapy."
Medicines called Artemisinin have been highly effective against malaria when used in combination with other drugs. Using a combination of drugs is called a "cocktail."
But in five countries in Southeast Asia -- Cambodia, Vietnam, Thailand, Myanmar and Laos -- the malaria organism, or parasite, has developed a resistance to the treatment. Drug-resistant means that the drug no longer treats the disease.
Doctors can still treat infected patients with stronger drug cocktails. But they worry that it is just a matter of time before those medicines also become ineffective.
Dr. Francois Nosten has been leading research on the Thai - Myanmar border for the past 30 years. He says that the clock is ticking, meaning time is running out.
"This is a global public health emergency because we could see in our studies that the progression of resistance is quite fast. For example in 2007 none of the patients were infected with a resistant parasite. In 2012, 80% of the patients are infected with the resistant parasite, so in just a few years the majority of the infections are caused by the resistant parasite."
Dr. Nosten wants a stronger method of dealing with resistant malaria to control its spread. He wants to give medicine to whole villages where the parasite can lie inactive and unseen in many people.
"What we predict is in order to stop the progression of artemisinin resistance, we need to eliminate malaria. It's not good to just reduce the number of cases, reduce the transmission of the disease, we need to eliminate the parasite."
Medical teams are making plans to give anti-malarial drugs in villages where many cases of malaria have been reported. Many are hoping that this effort will stop the spread of an increasingly dangerous parasite.

在泰国与缅甸边境，一个疟疾研究和治疗中心正在努力消灭或根除一种抗药型寄生虫，防止其传播至国外。VOA通讯员Steve Sandford在泰国报道 。
疟疾病例大量减少。但是Cindy Chu等医生仍然比较担忧 。
“过去，我们在Wangpha诊所经常看到许多疟疾病例，但是现在，由于根除疟疾的不懈努力，积极的监控，甚至边境另外一边设立了疟疾岗哨，疟疾患病率已大幅下降。所以，我们不像过去那样见到那么多疟疾 。另一方面，我们看到的疟疾更加复杂 。由于青蒿素抗药性，我们看到的病例需要额外的治疗 。”
过去30年，Francois Nosten医生领导在泰国缅甸边境的研究。他表示，倒计时已经开始，时间已经不多了 。
“这是全球性的公共健康紧急问题，因为我们在研究中可以看到，抗药性的发展非常快。例如，2007年，没有任何病人感染抗药性的疟疾 。2012年，80%的病患感染的是抗药性的疟疾，所以在几年的时间内，大部分病例都是由抗药性疟疾寄生虫造成的 。”
