Tb how is it contracted

TB disease in the lungs or throat can be infectious. This means that the bacteria can be spread to other people. TB in other parts of the body, such as the kidney or spine, is usually not infectious. People with TB disease are most likely to spread it to people they spend time with every day. This includes family members, friends, and coworkers or schoolmates. Learn about latent TB infection and TB disease.

Back to Tuberculosis TB. Tuberculosis TB is caused by a type of bacterium called Mycobacterium tuberculosis. It's spread when a person with active TB disease in their lungs coughs or sneezes and someone else inhales the expelled droplets, which contain TB bacteria.

Being around a person infected with TB, or even breathing in the air contaminated with tuberculosis germs, doesn't mean that you'll definitely get TB. However, certain people are more susceptible to the disease than others. People with healthy immune systems are better able to defend themselves against the progression of tuberculosis infection into active TB disease, while those with weakened immune systems — for instance, people with HIV — are much more susceptible to actually developing active tuberculosis disease.

The longer you spend with someone who has contagious TB, the greater the likelihood that you'll catch the illness. But even if you are infected with tuberculosis, you may still never get sick. Less than 10 percent of people who have been infected with the tuberculosis bacteria go on to develop active tuberculosis disease.

If you have tuberculosis, it's very important to take all medications exactly as prescribed and avoid contact with others until you are no longer contagious.

This confused me and really upset the man. We said nothing about it, but when we left my sister told me that people suspected he had TB, and touching the glass might have given me TB. There are also myths about how TB can be cured. In the Chief Minister of Uttarakhand in India, said that living in close proximity to a cow could cure a person of TB , which of course it can't.

This is done by firstly finding the adults who have TB. Particularly in countries with a high burden of TB , awareness of TB must be raised so that people with symptoms of TB know they should get help.

People with TB disease must then be provided with effective TB treatment which means that they will no longer be infectious and can no longer spread TB to other people. They will also usually then recover from being sick although the treatment for TB takes a long time. This page was last updated in December
