Tuberculosis is a contagious infection that usually attacks the human respiratory system especially the lungs.
Overview of Tuberculosis
Tuberculosis, also referred to as TB, is a contagious disease, but it cannot be spread easily as the bacteria cannot survive on exposed external surfaces. Any person who is in constant contact with an infected person has a high risk of contracting the disease. Therefore, co-workers, close family members, friends and anybody who is in proximity to the infected person is at a higher risk of being infected.
Tuberculosis is a disease caused by the bacteria Mycobacterium tuberculosis- can appear as either gram-negative or Gram-positive bacteria of the genus of Actinobacteria. Apart from the lungs, these bacteria can attack and spread to other parts of the body, including the brain, spine and the kidney.

Symptoms of Tuberculosis
Tuberculosis symptoms (TB symptoms) may not be immediately visible. This is because there are two forms of the disease-
- Latent Tuberculosis.
- Active Tuberculosis.
As the name suggests, latent tuberculosis doesn’t make the person sick or contagious. Though the causative microbe is present within them, the infected individual does not show any symptoms. This is because their immune system stops the microbes from spreading, but doesn’t completely kill it. This creates a window of opportunity for the microbes to become active one day.
Active TB can make the infected person sick and contagious. Most cases of adult TB stem from old latent TB infections.
Characteristic symptoms of TB symptoms include
- Chest pain
- Weight loss.
- Night Sweats.
- Loss of appetite.
- Excessive fatigue.
- Coughing up mucus streaked with blood.
- A persistent cough that lasts over 20-25 days.
