How does the tuberculosis infection invade and attack the body?

Answer 1

TB is an ancient infectious disease that has been around for over 30, 000 years. It is Caused by infection from Mycobacterium tuberculosis and in most cases affects the lungs. It is found worldwide. The bacilli spores are transmitted through the air when an infected person coughs or sneezes, but you have to spend quite a long time with an infected person in order to catch TB. It cannot be transmitted by objects such as bed linen or clothes, although it is possible to contract TB by drinking unpasteurised milk products from an infected cow.

Answer 2

* Tuberculosis (TB) is a serious, re-emerging bacterial illness that usually affects the lungs. * TB bacteria are spread from person to person through the air. * There are two forms of TB: 1) TB infection, and 2) TB disease (active TB). Most people with TB have infection. People with TB infection have no symptoms and cannot spread TB to others. People with TB disease have symptoms and can spread TB to others. * People with TB infection can take medicine to keep them from getting TB disease. People with TB disease can usually be cured with anti-TB drugs. To be effective, the drugs must be taken exactly as prescribed. Some new strains of TB are resistant to many anti-TB drugs. * Preventing TB involves: 1) keeping people from becoming infected with TB, 2) keeping people with TB infection from getting TB disease, 3) treating people with TB disease, and 4) implementing precautions in institutional settings to reduce the risk of TB transmission.

Answer 3

A person can become infected with tuberculosis bacteria when he or she inhales minute particles of infected sputum from the air. The bacteria gets into the air when someone has tuberculosis lung infection coughs, sneezes, shouts or spits ( which is common in some culture).

Answer 4

It is a bacterial disease. TB is carried in airborne particles or droplet nuclei.
The TB organism is projected airborne when an individual with active TB sneezes, coughs, speaks or sings.
Transmission requires close, frequent and/or prolonged exposures.
These particles are very small and may “float†on air currents for long periods of time.
Infection occurs when these particles are inhaled into the lungs, where it settles and begins to grow.

Answer 5

TB spreads in the air as a person coughs. In general, you would have to be in close contact for 8 hours with someone infected with TB. There are other, more infectious, mutations out there.

Answer 6

It is an infectious disease. It is caused by the tuberculosis germ. The germ can be spread by coughing, sneezing or contact.
