How+does+Tuberculosis+work?

Tuberculosis is an [|infectious disease] caused by [|microbacteri]a. Mycobacteria is a large family of bacteria that creates waxy cell walls that are resistant to digestion. Tuberculosis is mainly caused by the bacteria known as Mycobacterium Tuberculosis, but it can also be caused by other mycobacteria's like Mycobacterium bovis, Mycobacterium africanum, Mycobacterium canetti, and Mycobacterium microti though it dont always effect healthy adults. Tuberculosis can effect other areas besides your lungs.Like your [|central nervous system], your [|lymphatic system], your [|circulatory system], your [|genitourinary system], your bones,your joints, even your skin.The central nervous system (CNS) is a apart of the nervous system which is made up by the brain and the spinal cord. The lymphatic system is the system that is made up of organs and tissues that stores and produces white cells( which are cells that are produced by your body to fight off diseases and infection). The circulatory system is the system that moves the blood around your body, it is composed by the heart, the arteries, the capillaries, and the veins. The genitourinary system is the system in charge of reproduction and getting rid of the waste in our body.

When Tuberculosis first develops you don't actually feel anything so you don't actually know you have TB, thats why if you have any family members or people you know who has TB you should contact your doctor and make an appointment as soon as possible. When Tuberculosis becomes active in most of the cases are pulmonary Tuberculosis but in other cases the infection starts in the lungs and move into extrapulmonary infectious places. There are symptoms that can help know if you have an active pulmonary TB like coughing out blood, chest pain, an active coughing for weeks. The systemic( affecting the whole body) symptoms are fever, night sweats, loss of appetite, weight, loss, easy exhaustion, chills, extremely pale. Extrapulmonary TB is not contagious it might co-exist with pulmonary TB, and pulmonary TB is contagious. Pulmonary TB is contagious because when someone who has an active pulmonary TB cough, speak, sneeze, or spit they discharge contagious [|aerosol] droplets. Aerosol is a fine mist that contain small particles. For example, one sneeze can release 40,000 droplets. With a single droplet inhaled it can developed a new infection.

There are different stages to Tuberculosis. The first stage is Exposure, when person has been in contact or exposed with someone who has or had TB. When tested, this person has a negative TB, no symptoms of TB, and a normal chest x-ray. The second stage is TB infection, when a person already has the bacteria in her body but doesn't have the symptoms. This person will have a normal x-ray but a positive TB skin test. The third stage is TB disease, when a person already has the symptoms and signs. This person has a positive TB skin test, and a positive chest x-ray.
