Public Health Wales says tuberculosis (TB) is a curable infectious disease.
TB is potentially very serious and can be fatal.
It causes more deaths worldwide than any other single infectious disease, but declined rapidly in the twentieth century in Wales and other industrialised nations.
Public health officials are notified of around 200 cases of TB each year in Wales.
- The infection is usually found in the lungs, but any part of the body can be affected
- Anyone can catch TB by breathing in the bacteria in tiny droplets sneezed or coughed out by someone who has TB in their lungs
- The most common symptom is a persistent cough for more than three weeks, with spit which can sometimes be blood-stained
- Other symptoms can include weight loss, a high temperature, and sweating, particularly at night
- TB is curable with a full course of treatment
Anyone who is concerned about their health should speak to their GP or contact NHS Direct Wales on 0845 46 47.
