What does tuberculosis do to you


What does tuberculosis do to you?
We were having a discussion in art lesson this afternoon, and our teacher showed us her scar from the needle she had against tuberculosis. When we asked her what tuberculosis was, she didn't know. She also said that you don't need the vaccination unless your someone in your family got tuberculosis. Is this true?

Tuberculosis (TB) is an infection caused by slow-growing bacteria that grow best in areas of the body that have lots of blood and oxygen. That’s why it is most often found in the lungs. This is called pulmonary TB. But TB can also spread to other parts of the body, which is called extrapulmonary TB. Treatment is often a success, but it is a long process. It takes about 6 to 9 months to treat TB. Tuberculosis is either latent or active. Latent TB means that you have the TB bacteria in your body, but your body’s defenses (immune system) fight the infection and try to keep it from turning into active TB. This means that you don't have any symptoms of TB right now and can't spread the disease to others. If you have latent TB, it can become active TB. Active TB means that the TB bacteria are growing and causing symptoms. If your lungs are infected with active TB, it is easy to spread the disease to others. Most of the time when people are first infected with TB, the disease is so mild that they don't even know they have it. People with latent TB don't have symptoms unless the disease becomes active. Symptoms of active TB may include: A cough that brings up thick, cloudy, and sometimes bloody mucus from the lungs (called sputum) for more than 2 weeks. Tiredness and weight loss. Night sweats and a fever. A rapid heartbeat. Swelling in the neck (when lymph nodes in the neck are infected). Shortness of breath and chest pain (in rare cases). Without treatment, active TB can cause serious complications, such as: Pockets or cavities that form in the lungs. These damaged areas may cause bleeding in the lungs or may become infected with other bacteria and form pockets of pus (abscesses). A hole that forms between nearby airways in the lungs (bronchopleural fistula). Difficulty breathing because of blocked airways. TB can be fatal if it is not treated. Active TB that occurs outside the lungs (extrapulmonary TB) is not spread easily to other people. You take the same medications that are used to treat pulmonary TB. You may need other treatments depending on where in your body the infection is growing and how severe it is.

Tuberculosis is spread through the air, when people who have the disease cough, sneeze, or spit. One third of the world's current population have been infected with M. tuberculosis, and new infections occur at a rate of one per second.[2] However, most of these cases will not develop the full-blown disease; asymptomatic, latent infection is most common. About one in ten of these latent infections will eventually progress to active disease, which, if left untreated, kills more than half of its victims. In 2004, mortality and morbidity statistics included 14.6 million chronic active cases, 8.9 million new cases, and 1.6 million deaths, mostly in developing countries.[2] In addition, a rising number of people in the developed world are contracting tuberculosis because their immune systems are compromised by immunosuppressive drugs, substance abuse, or AIDS. The distribution of tuberculosis is not uniform across the globe with about 80% of the population in many Asian and African countries testing positive in tuberculin tests, while only 5-10% of the US population testing positive.[1] It is estimated that the US has 25,000 new cases of tuberculosis each year, 40% of which occur in immigrants from countries where tuberculosis is endemic.[1]

Ask not what tuberculosis can do for you but what you can do for tuberculosis. My first suggestion is an immunization. My second suggestion is to enjoy the time you have left. I would probably go get some ice cream and watch a movie.

It's a nasty infection, and one that if not treated is extremely contagious and is fatal. it attacks most of your body's systems, gives you fever, chills, fatigue, night sweats, and the common symptom of coughing up blood. And as far as I know, you are required to have TB shots before attending any sort of public school, and definitely so if you are working with patients, or foods.

Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you have been exposed, you should go to your doctor for tests. You are more likely to get TB if you have a weak immune system. Symptoms of TB in the lungs may include A bad cough that lasts 3 weeks or longer Weight loss Coughing up blood or mucus Weakness or fatigue Fever and chills Night sweats If not treated properly, TB can be deadly. You can usually cure active TB by taking several medicines for a long period of time. People with latent TB can take medicine so that they do not develop active TB. When the inhaled tuberculosis bacteria enter the lungs, they can multiply and cause a local lung infection (pneumonia). The local lymph nodes associated with the lungs may also become involved with the infection and usually become enlarged. The hilar lymph nodes (the lymph nodes adjacent to the heart in the central part of the chest) are often involved. In addition, TB can spread to other parts of the body. The body's immune (defense) system, however, can fight off the infection and stop the bacteria from spreading. The immune system does so ultimately by forming scar tissue around the TB bacteria and isolating it from the rest of the body. Tuberculosis that occurs after initial exposure to the bacteria is often referred to as primary TB. If the body is able to form scar tissue (fibrosis) around the TB bacteria, then the infection is contained in an inactive state. Such an individual typically has no symptoms and cannot spread TB to other people. The scar tissue and lymph nodes may eventually harden, like stone, due to the process of calcification of the scars (deposition of calcium from the bloodstream in the scar tissue). These scars often appear on x-rays and imaging studies like round marbles and are referred to as a granuloma. If these scars do not show any evidence of calcium on x-ray, they can be difficult to distinguish from cancer. Sometimes, however, the body's immune system becomes weakened, and the TB bacteria break through the scar tissue and can cause active disease, referred to as reactivation tuberculosis or secondary TB. For example, the immune system can be weakened by old age, the development of another infection or a cancer, or certain medications such as cortisone, anticancer drugs, or certain medications used to treat arthritis or inflammatory bowel disease. The breakthrough of bacteria can result in a recurrence of the pneumonia and a spread of TB to other locations in the body. The kidneys, bone, and lining of the brain and spinal cord (meninges) are the most common sites affected by the spread of TB beyond the lungs.

I had a TB test done for my school when I was applying for the Nursing program. I found a link that explains what it is, what kind of vaccination you can get, etc.

it's bad. It's an infection that you can get by breathing infected air. Onc the germs get into your bloodstream, they set up shop where ever they can, throughout the body but most commonly in lungs. They eat up the normal tissue and make little pockets of infection. The cough is vey bad (I always avoid people with really deep, grumbly coughing just in case). There is not much of it in the US anymore, but heathcare workers are tested annually to see if they have been exposed to it. If the test is positive, they get a six-month course of antibiotics and frequent chest x-rays to be sure infection pockets ("tubercles") are not developing.

Kelly T, TB, or tuberculosis, is caused by a bacterium called Mycobacterium tuberculosis. The bacteria can attack any part of the body, but most frequently attacks the lungs. TB of the lungs and throat is infectious. When a person with TB of the lungs coughs or sneezes, TB bacteria spread into the air. People nearby may breathe in these bacteria and become infected. When a person breathes in TB bacteria, the bacteria settle in the lungs and begin to grow. From there, they may move through the blood to other parts of the body, such as the kidney, spine or brain. People who are infected with TB do not feel sick, do not have any symptoms, and cannot spread TB. But they could develop TB disease at some time in the future. Some people develop TB disease soon after becoming infected when TB bacteria begin to multiply rapidly, before their immune system can fight back. Other people may get sick later, when their immune system becomes weak for some reason. TB in other parts of the body, such as the kidney or spine, is usually not infectious. The most common symptoms of TB are – cough, fever, especially rising in the evening, night sweats, chest pain, weight loss, loss of appetite, coughing up of blood. BCG is a vaccine for TB. This vaccine is given to infants and small children. BCG (Bacille Calmette-Guérin) vaccine protects against the severe, life-threatening forms of TB such as TB meningitis and miliary TB in childhood. However, it does not protect people from TB later in their life. Mantoux test is an intracutaneous tuberculin test using either old tuberculin (OT) or purified protein derivative (PPD). A positive reaction read 24 and 48 hours after injection shows erythema and edema greater than 5 mm in diameter and indicates past or present tuberculosis. The vaccine is not usually offered unless a person is expected to come into contact with the disease. It used to be given in the armed forces to boys previous to the completion of their training. But I believe that this practice is no longer continued. ALL ANSWERS SHOULD BE THOROUGHLY RESEARCHED, IN ANY FORUM AND ESPECIALLY IN THIS ONE. MANY ANSWERS ARE FLAWED. The information provided here should not be used during any medical emergency or for the diagnosis or treatment of any medical condition. A licensed physician should be consulted for diagnosis and treatment of any and all medical conditions. Hope this helps matador 89

Tuberculosis – What is it? Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you think you have been exposed, you should go to your doctor for tests as soon as possible. You are more likely to get TB if you have a weak immune system. How Does TB Spread? All types of TB (see “Drug-resistant TB” below) are spread the same way. TB germs are put into the air when a person with TB disease of the lungs or throat coughs, sneezes, speaks, or sings. These germs can float in the air for several hours, depending on the environment. Persons who breathe in air containing these TB germs can become infected.TB is not spread by: Shaking someone's hand Sharing food or drink Touching bed linens or toilet seats Sharing tooth brushes Kissing Smoking or sharing cigarettes http://www.hhs.gov/tb
