健康报道 - 抗药性肺结核病蔓延

This is the VOA Special English Health Report.


In December, doctors in Mumbai, India, reported about a group of patients with what they called "totally drug-resistant" tuberculosis. Indian health officials have been investigating these cases. But there have been reports of untreatable cases of TB in the past. Doctors reported fifteen patients in Iran in two thousand nine and two patients in Italy in two thousand seven.


Tuberculosis is a bacterial disease that usually targets the lungs. It causes an estimated five thousand deaths each day, or about two million a year.


TB can be spread through the air when an infected person coughs or sneezes or even speaks.


Some forms of TB bacteria no longer react to one or more of the antibiotics commonly used to cure the disease. These are known as drug-resistant strains. Some resist even more drugs. The World Health Organization says sixty-nine countries have reported cases of "extensively drug-resistant" tuberculosis. The WHO says at least twenty-five thousand such cases are reported worldwide every year.


The agency's director-general, Dr. Margaret Chan, is concerned about the spread of drug-resistant TB.

MARGARET CHAN: "Call it what you may, a time bomb or a powder keg. Any way you look at it, this is a potentially explosive situation."


Officials say drug-resistant TB has been a growing problem in countries like India and China. In many cases, doctors misdiagnose patients or give them the wrong treatment or not enough treatment. Misuse of these antibiotics increases the danger that the bacteria will develop resistance to them.


Neeraj Mistry is a public health doctor. He says surveys show that very few Indian doctors are treating TB patients with the right drugs for the right length of time. Another problem is that patients may not take all of their medicine.

Neeraj Mistry是一名公共卫生医生。他说,调查表明,很少有印度医生针对患病时间长短采用正确的药物来治疗结核病患者。另一个问题是,病人可能没有服用医生所开的全部药物。

NEERAJ MISTRY: "The emergence of totally-resistant TB is a result of failed public health intervention strategies. When we deliver ineffective treatment regimens and when we don't have full adherence and compliance to treatment, it enables the emergence of resistance within the individual."

NEERAJ MISTRY:“完全抗药性结核病的出现是公共卫生干预策略失败的结果。当我们提供无效的治疗方案,当我们没有完全遵守或配合治疗,就会使得个体抗药性的出现成为可能。”

The WHO says new, stronger TB drugs could be available by the end of this year or early twenty-thirteen.


Researchers are also working on vaccines to prevent the disease. Dr. Ann Ginsberg works at the Aeras Global TB Vaccine Foundation. She says the development process takes a long time, partly because people often do not get sick for years after getting infected with TB.

研究人员还致力于预防这种疾病的疫苗。Ann Ginsberg博士在AERAS肺结核疫苗基金会工作。她表示疫苗开发过程需要很长时间,部分原因是因为人们感染肺结核多年后才会发病。

ANN GINSBERG: "So when you do a vaccine trial, you have to vaccinate people and watch them for years."

ANN GINSBERG:“所以当你进行疫苗试验时,你必须对人们进行疫苗接种并观察多年。”

And that's the VOA Special English Health Report. I'm Bob Doughty.
