tuberculosis

Tuberculosis (TB) is a disease caused by a germ that is spread from person to person through the air. TB usually affects the lungs, but can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with active TB can die if they do not get treatment. The general symptoms include feelings of sickness or weakness, weight loss, fever, night sweats, coughing, chest pain and coughing of blood. It should be noted that symptoms of TB disease in other parts of the body depend on the affected area. TB germs are put into the air when a person with the disease coughs, sneezes, speaks or sings. These germs can stay in the air for several hours, depending on the environment. People who breathe in the air containing these TB germs can become infected. Those with the infection, but who have no symptoms, are considered to have "latent TB."

They may develop TB disease later in life if they do not receive treatment for latent TB infection. People cannot be infected by the TB germ through handshakes, sitting on toilet seats, or sharing dishes or utensils with someone who has TB.

Usually treatment with isoniazid for about nine months or rifampin for six months can prevent a latent TB infection from developing to active TB. Treatment is recommended for anyone who has a positive skin reaction and is especially important for people who:

Active tuberculosis is an infection that is spreading in a person's body and is very contagious. The World Health Organization estimates that one third of the world's population is infected with bacteria that cause TB.
