MULTIDRUG RESISTANT TUBERCULOSIS IS SOMETHING WE SHOULD ALL BE THINKING ABOUT, ELIZABETH TRACEY REPORTS
Tuberculosis may be poised to regain its killer status worldwide as multidrug resistant forms develop and are easily spread via air travel. David Bishai, a TB expert at Johns Hopkins, and colleagues, have developed a model to predict spread of the disease.
BISHAI: Our model is focusing on one of what we think has been a traditional protective factor, which is that people in most countries have always had some exposure to the ordinary wild type tuberculosis, and that creates some immunity. Historically, Americans, and today all the people in India and China, have gone through childhood with a high likelihood of being exposed to ordinary tuberculosis, which gives them some resistance to any multidrug resistant that comes along. Now in the US that’s no longer true. :31
Bishai says multidrug resistant TB fails to respond to at least two of the primary antibiotics used to treat the disease, while extreme drug resistant TB doesn’t respond to any. At Johns Hopkins, I’m Elizabeth Tracey.
