Tuberculosis

Tuberculosis (TB) is often thought of a disease from the past. However, it remains one of the three main killer infectious diseases, particularly in developing countries.
Most people never develop symptoms, however those with a weakened immune system are particularly vulnerable, including the elderly, malnourished and people living with HIV.
The disease is spread through the air when infected people cough or sneeze. Symptoms include a persistent cough, fever, weight loss, chest pain and breathlessness in the lead up to death.
Treatment can take a minimum of six months, however for patients who develop drug-resistant TB, treatment can be tough, taking up to two years, with many side-effects.
