tuberculosis can exist in the air for up to six hours, during which time another person may inhale it. M. tuberculosis does not discriminate against the people whom it meets. It is estimated that every second, a new person is infected with TB.
Does Tuberculosis stay in your system forever?
Many people who have latent TB infection never develop TB disease . In these people, the TB bacteria remain inactive for a lifetime without causing disease . But in other people, especially people who have weak immune systems, the bacteria become active, multiply, and cause TB disease .
Is TB airborne or droplet?
M. tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.
Is the common cold airborne?
The common cold is very easily spread to others. It’s often spread through airborne droplets that are coughed or sneezed into the air by the sick person. The droplets are then inhaled by another person. Symptoms may include a stuffy, runny nose, scratchy, tickly throat, sneezing, watery eyes and a low-grade fever.

Chlorine bleach is often used to disinfect TB cultures and clinical samples, but bleach is toxic and corrosive. Other effective commercial disinfectants can be too expensive for TB labs in the resource-poor countries where the majority of TB occurs.
What are the chances of getting TB if exposed?
Active tuberculosis was diagnosed in 9.5% of contacts with evidence of infection, but most cases involved “coprevalent” disease detected during the first 6 months.
How long can TB bacteria live on surfaces?
Besides the direct transmission from an infected person to an uninfected person, the TB bacilli can also be transmitted by dust. Once coughed out by a person with TB, the bacilli can survive up to six months outside the body if they are protected from direct sunlight. Often they settle in dusty, dark areas.
How do I disinfect my house after TB?

How easy is it to get TB from a patient?
Although tuberculosis is contagious, it’s not easy to catch. You’re much more likely to get tuberculosis from someone you live with or work with than from a stranger. Most people with active TB who’ve had appropriate drug treatment for at least two weeks are no longer contagious.
What are the isolation precautions for tuberculosis?
Persons who have or are suspected of having infectious TB disease should be placed in an area away from other patients, preferably in an airborne infection isolation (AII) room.
