Tuberculosis (TB) is a bacterial infection that most commonly affects the lungs, but can also affect the lymph nodes, bones, joints and kidneys. It can cause meningitis.

Symptoms

People with tuberculosis don’t always show symptoms.

The most common symptoms are: a cough lasting 3 weeks or more, often with thick phlegm, tiredness, night sweats, weight loss, swollen glands (usually in your neck).

How it is spread?

Tuberculosis is spread through coughing, sneezing or spitting. The bacteria are carried into the air and people nearby can breathe them in through their mouths and noses.

Prevention

Immunisation is available for people at high risk.
