Tuberculosis (TB)

Tuberculosis (TB) is a lung disease caused by a bacterium named Mycobacterium Tuberculosis. Most of the population, if not all, have latent TB. This means that they have been infected by the bacteria but are not ill with the disease and cannot spread it.
Those who are immunocompromised such as people who are living with HIV, have malnutrition, severe kidney disease, cancer, diabetes or those who use tobacco have a greater probability of falling ill with the disease. 1
TB is curable and preventable. 1
