What is Tuberculosis?

Tuberculosis (TB) is a contagious infectious disease. It is transferable from one person to another by air, direct contact like kissing and drinking from a glass with infected saliva.  Although TB is contagious, it may take a while for the infection to begin, depending on the strength of the immune system.

The bacteria called Mycobacterium tuberculosis usually causes the disease, which is either latent or active. Latent tuberculosis is inactive and not contagious. This means the infection is present and the bacteria remain in the system. But symptoms do not occur and the infection may not spread. Although latent tuberculosis is inactive it has a 10 percent chance of becoming active due to lifestyle, environmental factors and immune system failure

Active tuberculosis, meanwhile, makes a person sick, with obvious symptoms. It may occur a few weeks after the infection or many years later. It is transferable to another person.

Diagnosis and Tests

1. Acid-fast Bacillus Stain 

This test helps in identifying the presence of Mycobacterium tuberculosis and other bacterial infection.

2. Chest X-Ray

This test may aid in diagnosing if the patient has tuberculosis, heart disease, and pneumonia. Further testing is advisable if x-ray results show opacity or very light areas around the lung area.

3. TB Skin-Test

This screens people who are at risk of TB due to a very weak immune system or prolonged exposure. A type of protein is injected on the first layer of the skin to identify TB presence.
