How can someone get tuberculosis?

Tuberculosis (TB) is a bacterial infection that is caused by the bacterium *Mycobacterium tuberculosis*. It can be spread through the air when an infected person coughs, sneezes, or speaks. TB can also be spread through contact with infected bodily fluids, such as blood or saliva.

The most common way to get TB is through close contact with someone who is already infected with the bacteria. This is why it is important to avoid contact with people who are known to have TB. You can also get TB from animals, such as cattle or deer, but this is less common.

TB can be a serious disease, but it can be treated if it is caught early. If you have any of the symptoms of TB, such as a persistent cough, shortness of breath, or chest pain, it is important to see a doctor right away.

Here are some tips to help you prevent TB:

* Get vaccinated against TB. The TB vaccine is available to people who are at high risk of getting the disease, such as children who live in high-risk areas or people who have HIV.

* Avoid contact with people who are known to have TB.

* If you are in close contact with someone who has TB, wear a face mask and wash your hands frequently.

* Keep your immune system strong by eating a healthy diet and exercising regularly.

* Get regular checkups with your doctor.
