Extensively Drug-Resistant Tuberculosis

Extensively Drug-Resistant Tuberculosis (XDR-TB) is a form of tuberculosis that is resistant to at least four of the most commonly used anti-TB drugs. It is a serious concern for public health, as it is more difficult to treat and has a much higher risk of recurrence than regular TB infection. XDR-TB is most commonly found in areas with a high prevalence of regular TB, but can also occur in low prevalence areas. Treatment is often prolonged and expensive, and there is no vaccine available. As such, early detection and prevention are key in effectively combating this deadly disease.
