How is pulmonary tb spread?

Pulmonary TB is spread through the air when an infected person coughs, sneezes, or speaks, releasing tiny droplets. It is highly contagious, so if someone has a persistent cough, it is best to consult a doctor for a sputum test.

TB spreads very easily through coughing in closed spaces. Please, if you or anyone in your house has had a cough for more than two weeks, go to a government health center or doctor and get a chest X-ray done immediately.

I didn't know it spreads through the air when people talk. Does this mean we should keep windows open at home if someone has a chronic cough, or will that make it worse?

When my sister had TB, we were so scared of it spreading to the whole family. It spreads through the air when the patient coughs, but keeping her in a well-ventilated room and making her wear a mask saved us all. It's a stressful time, but you will get through it.

It spreads simply through the air when people cough without covering their mouths, which is classic in our crowded buses. Best is to wear a mask and keep some distance. No need to stop talking to people, just keep some hygiene!

Don't panic, pulmonary TB only spreads when you breathe in the droplets from an infected person's cough. It does not spread by sharing utensils or shaking hands. Just ensure the patient wears a mask and completes their DOTS therapy.
