Indian doctors have reported the country’s first cases of “totally drug-resistant tuberculosis,” a long-feared and virtually untreatable form of the killer lung disease.
It’s not the first time highly resistant cases like this have been seen. Since 2003, patients have been documented in Italy and Iran. It has mostly been limited to impoverished areas, and has not spread widely. But experts believe there could be many undocumented cases.
No one expects the Indian TB strains to rapidly spread elsewhere. The airborne disease is mainly transmitted through close personal contact and isn’t nearly as contagious as the flu. Indeed, most of the cases of this kind of TB were not from person-to-person infection but were mutations that occurred in poorly treated patients.
What’s more, there’s a debate within the public health community about whether to even label TB infections as totally drug resistant. The World Health Organization hasn’t accepted the term and still considers the cases to be what’s now called extensively drug-resistant TB, or XDR. However, Dr. Paul Nunn, a coordinator at the WHO’s Stop TB Department in Geneva, said there is ample proof that these virtually untreatable cases do exist.
