Tuberculosis may survive in the air for up to six hours, during which time it can be inhaled by another person. M. tuberculosis does not discriminate against those who are infected with it. Every second, a new individual is infected with tuberculosis.
The bacteria that cause tuberculosis are found everywhere in the world, but they don't live outside of the human body for more than 24 hours. This means that someone who is not infected with the disease cannot get it from an aerosolized source such as a cough. However, if someone is already infected, the disease is able to spread through the air.
When an infected person breathes out vapor or mist droplets containing the bacteria, this is called "exhaling into lung secretions" or "exhaling into bronchial fluids." The virus can remain active even after being frozen or dried out. This is why it's important to keep infected tissue specimens on hand for research purposes. These samples can be stored indefinitely in a laboratory freezer if needed later for testing.
People who know they have been exposed to M. tuberculosis but do not show signs and symptoms of the disease can be treated with antibiotics. This is usually done when there is a high risk of exposure to the bacteria. For example, health care workers who handle tuberculosis patients in hospitals often receive preventive treatment while patients are still infectious.
Although TB is infectious, it is difficult to contract. You are significantly more likely to contract TB from someone with whom you live or work than from a stranger. Most persons with active tuberculosis who have had adequate medication therapy for at least two weeks are no longer infectious. /span>
The only way to catch TB is through the air you breathe or the liquid in your lungs. Someone who has been diagnosed with TB may be treated with antibiotics to kill any bacteria they may be breathing out and to prevent the development of more severe symptoms. This does not protect others against contracting the disease.
TB is a bacterial infection that can affect the lungs or the brain. It can be deadly if not treated. The only way to avoid TB is by avoiding exposure to people who are infected with the virus. Children under five years old, pregnant women, and people with compromised immune systems are at highest risk for developing TB. Those people should take special precautions to avoid contact with others.
The best defense against TB is a strong immune system. If you have HIV/AIDS or another condition that weakens the immune system, you are at increased risk for developing TB. People with weakened immune systems also are at higher risk for other infections, such as pneumonia. They need to be monitored regularly by a health care provider who can identify signs of TB infection or disease early on.
Tuberculosis is both treatable and avoidable. Tuberculosis spreads through the air from person to person. When persons with lung tuberculosis cough, sneeze, or spit, the TB germs are released into the air. Only a few of these germs must be inhaled for a person to get sick.
However, there are many drugs available that can cure people of TB. These drugs work by killing the bacteria that cause the disease. In addition, there are vaccines available that protect people against TB. This article will discuss what causes TB, how it is treated, and what causes some people to be more susceptible to the disease.
TB is a chronic disease that can re-occur if treatment is not continued for long enough. Some people are at risk of developing drug resistance when taking antibiotics. This is because certain types of bacteria can change themselves into forms that are less likely to be killed by antibiotics. These resistant bacteria can then spread to other people who are infected with them. Research is ongoing into identifying new classes of drugs that are more effective against TB than those currently on market.
The only way to prevent TB is by being vaccinated and/or by not exposing others to your contagious droplets. The vaccine is administered in two doses, six months apart. The first dose is given as an injection, while the second dose is delivered via a nasal spray. Children under the age of five years old may also receive a third dose of the vaccine.
Tuberculosis (TB) is virtually always cured with the right therapy. Antibiotics are prescribed by doctors to destroy the bacterium that causes it. You must take these for 6 to 9 months. After finishing a course of antibiotics, you should not get re-infected with TB. If you do get re-infected with TB, then more than likely your treatment failed.
Antibiotics can have an effect on TB that is called "antitubercular activity". This means that they may slow down the growth of TB bacteria or help cure people of TB. However, antibiotics cannot kill TB bacteria. They only kill the bacteria that cause infection. If you are taking antibiotics for another reason, ask your doctor if there are any changes you should make during your treatment for TB.
People who are infected with HIV and also have tuberculosis usually die from something else first. In this case, tuberculosis itself is not what kills them, but other problems such as AIDS itself. People who are not infected with HIV can still be cured of tuberculosis. The same thing can happen to people who are already sick with HIV. Their immune systems can be strong enough to beat back the tuberculosis bacteria and they can be cured.
People who are infected with HIV and also have tuberculosis often do not respond well to drug treatments.
