Prophylactic treatment for tb if what?

Diet/Exercise: Tb was common many years ago until hygiene, diet and housing became better. Prophylactic treatment is appropriate diet using "god-made" food, open air exercise and adequate rest. Notice that TB is returning because of a lapse in good health tactics including becoming "couch potatoes" and our extremely poor diet filled with empty calories.

INH: If you have a positive skin test and normal chest radiograph, then INH is used to prevent TB disease.

Easy: Appropriate diet, exercise, good hygiene, happiness--- in fact what we all should bedoing.
