In India, it's quite common to be misdiagnosed with tuberculosis by unreliable health care workers at community clinics using less-than-accurate blood tests, says The New Yorker's Michael Specter. When these misdiagnosed patients take the antibiotics they're required to take for six months, they actually end up waking up any latent TB infection, only they've also made the TB drug resistant, and have a higher chance of passing it on to others and dying from it.
