What is Tuberculosis:
Tuberculosis is a serious, contagious bacterial infection affecting lungs. It is generally caused by the bacteria called Mycobacterium tuberculosis. Other variants of Mycobacterium may also cause TB. This bacteria spreads from person to person through air.
Symptoms of tuberculosis vary according to the seriousness of the disease. There are two levels of TB: TB infection and TB disease.
In TB infection there are no prominent symptoms seen and it cannot spread to others as the bacteria is not yet grown. TB disease shows several symptoms such as:
- Severe cough that lasts for two weeks or more than two weeks
- Sharp pain in the chest region
- Cough with blood or sputum
- Loss of appetite
- Night Sweats
- Unexplained weight loss

These are the primary symptoms. Anyone observing these symptoms should rush to a health care professional immediately. Otherwise TB can spread to other parts of the body arising severe complications like lung failure, kidney failure and even death.
