Likewise, is it safe to be around someone with TB?

It is very important to remember that only someone with active TB disease in the lungs can spread the germ. People with TB infection are not contagious, do not have any symptoms, and do not put their family, friends and co-workers at risk.

how can family members protect themselves from TB? Here are some very important things you should do to prevent spreading your TB germs to other people: Always cover your mouth and nose when you cough or sneeze. Some people cough less when they drink warm liquids. While at home, spend only a short time in rooms that other people use like the bathroom or kitchen.

It is important to know that a person who is exposed to TB bacteria is not able to spread the bacteria to other people right away. Only persons with active TB disease can spread TB bacteria to others. Before you would be able to spread TB to others, you would have to breathe in TB bacteria and become infected.

How long do you have to be around someone to get TB?

Most people with active TB who've had appropriate drug treatment for at least two weeks are no longer contagious.

TB is not a genetic disease, but if a member of the family has it, and there is overcrowding in a home among other risk factors, another family member is more likely to get it.

Can you get TB by sharing a drink?

The TB germs enter the air when a person with active TB disease of the lungs or throat coughs, sneezes, speaks, or sings. TB is NOT spread by shaking someone's hand, sharing food or drink, touching bed linens or toilet seats, sharing toothbrushes or kissing. Not everyone who has the TB germ in their body becomes sick.

How do you know if you have been exposed to TB?

A positive skin or blood test means you have been infected with the germs—Latent (inactive) Infection. If you have a positive test, you will need a chest x-ray to find out if the germs have caused any damage in your lungs—Active Disease. You may be asked to cough up sputum (mucus) from your lungs to check for TB germs.

How long until TB is no longer contagious?

Even before a TB diagnosis, people can unwittingly transmit tuberculosis to others. People with symptomatic TB are contagious until they have taken their TB medications for at least two weeks. After that point, treatment must continue for months, but the infection is no longer contagious.

Is TB infectious or contagious?

Yes, TB is highly contagious and can be transmitted from an infected person to an uninfected person, mainly when a person with TB coughs, sneezes, speaks, or even sings (known as airborne transmission or airborne disease). Other people who breathe in the aerosolized bacteria can become infected.

What happens if I test positive for TB?

A positive test result means only that TB bacteria has been detected. It does not indicate whether the person has active TB or a latent infection. This requires additional testing, such as a chest X-ray and sputum sample, which tests the thick mucus from the lower respiratory tract.

How does tuberculosis enter the body?

When a person gets active TB disease, it means TB bacteria are multiplying and attacking the lung(s) or other parts of the body, such as the lymph nodes, bones, kidney, brain, spine, and even the skin. From the lungs, TB bacteria move through the blood or lymphatic system to different parts of the body.

Genevie Heiden


What is considered a positive TB test?

A tuberculin reaction is classified as positive based on the diameter of the induration in conjunction with certain patient-specific risk factors. In a healthy person whose immune system is normal, induration greater than or equal to 15 mm is considered a positive skin test.
