How is TB spread?
TB spreads when someone who has pulmonary TB coughs. TB bacteria from that person's lungs are then expelled into the air, and may be inhaled into the lungs of another person. TB is not very infectious; it's much harder to catch than the common cold. Usually a lot of time needs to be spent with a person with pulmonary TB for someone to catch TB. It's not possible to get TB from sharing a glass with a person with TB or touching a doorknob after someone with TB has used it. Also, once a person with TB is on medication he or she quickly becomes non-contagious. People on medication can quickly resume their normal patterns of life without fear of spreading TB to others.
