What is Tuberculosis?
Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis and is often shortened to TB. It can affect other body parts, but it most commonly attacks the lungs, where it is known as pulmonary tuberculosis. The infection spreads from person to person when tiny droplets are released into the air when someone with active TB coughs, sneezes or speaks.
Not everyone infected with the bacteria becomes unwell. Many people have what is called latent tuberculosis. This is when the bacteria remain dormant in the body and cause no symptoms and this form is not contagious. Latent infection can, however, progress to active disease when the immune system cannot keep the bacteria under control.
It has been around for centuries, but tuberculosis still remains a significant global health concern. Tuberculosis treatment, when managed correctly by experienced specialists, is highly effective.
