I'm really worried because I've been diagnosed with what they're calling infective etiology Koch's. Is this a really serious condition? Also, is there a treatment available for it?

Koch's disease, commonly known as tuberculosis (TB), is a serious infectious disease, but it is treatable with a course of antibiotics, typically lasting 6-9 months. Early diagnosis and consistent treatment are key to a full recovery, so it's important to follow your doctor's advice closely.
