Tuberculosis infection is a serious and deadly disease caused by bacteria. It spreads from person to person through air. TB mainly affects the lungs. It also affects other body parts like kidneys, bones and brain. There are two types of TB: Latent TB (Inactive) and TB disease (Active). Latent TB doesn’t spread but the person having latent TB should take medication to prevent it from becoming active. Active TB can spread and affect others. Here are some ways in which you can prevent tuberculosis (TB) from spreading from people who have active TB.

Stay at home

People who are suffering from active tuberculosis should not go outside during the first few weeks of treatment. They should not go to school or work or sleep with other people in the same room.

Ventilation of the room

The room where the person affected by TB is staying should be properly ventilated. This is because it is found that tuberculosis germs spread easily in closed space because there is no movement of air.

Finish the entire course of medication

Patients suffering from TB must always finish the entire medication course, which can last from six months to an entire year. Skipping doses or stopping the medication early would lead the TB bacteria to mutate due to which they can survive the most potent TB drugs. The mutated bacteria cause a more deadly TB which becomes difficult to treat.
