TB is a disease caused by bacteria called Mycobacterium tuberculosis. These germs can be spread from one person to others. These germs can be spread through the air when a person with TB disease coughs, sneezes, yells, or sings. Children, although they may be infectious, usually are not as likely as adults to transmit TB to others. (TB is not spread by objects such as clothes, toys, dishes, walls, floors, and furniture.) When a person is sick from the TB germ, the person has TB disease. TB can be serious for anyone, but is especially dangerous for children younger than 5 years old and for any persons who have weak immune systems, such as those with HIV or AIDS.
Tuberculosis kills 3,000,000 people in the world every year, more than AIDS, malaria, and other tropical disease combined. One third of the world's population is infected with tuberculosis. Tuberculosis is the leading infectious disease cause of death and represents more than a quarter of the world's preventable deaths.
Generally, return of dormant tuberculosis infection occurs in the upper lungs. Symptoms include
- common cough with a progressive increase in production of mucus and
- coughing up blood.
- Other symptoms include the following:
- loss of appetite,
- weight loss, and
- night sweats.
When complicated is also known as miliary TB, and often occurs in immunocompromised patients (such as HIV patients) or after extensive pulmonary disease leads to the spread of TB via the bloodstream. It can affect any organ, but most commonly attacks the liver, bone marrow, kidneys, adrenal glands and spleen. Symptoms can vary depending on the organ involved, from decreased oxygenation of the blood to a widespread bacterial infection of the blood (sepsis), and can be fatal much of the time.
