Tuberculosis (TB): Symptoms, Diagnosis and Treatment



Tuberculosis is a deadly disease, it is one of the top ten causes of death. According to records, in 2017, 10 million people were affected by Tuberculosis and 1.6 million died. TB is a disease that affects your lungs. It has the potential to affect other parts of the body as well such as the brain, kidney, and spine, etc. It is caused by bacteria called Mycobacterium tuberculosis. The presence of bacteria does not always harm the person. These bacteria harm persons who have a weak immune system. Otherwise, the immune system protects from becoming sick. Once the immune system of the person is weakened then this bacteria can harm the person. A weak immune system can be due to HIV, Diabetes, Cancer Treatment (Chemotherapy) and Malnutrition, etc. It is also a contagious disease, which means it spread from person to person.

Types of Tuberculosis

There are two types of TB based on severity.

  • Inactive TB (Latent TB)
  • Active TB

Inactive TB

This type of TB is also known as Latent TB. This is the very first stage when the bacteria are found in your body. The bacteria remain ineffective and you cannot see symptoms in this type. The immune system of the person protects him. After some time, it changes into Active TB and shows its symptoms when the immune system becomes weak. Inactive TB can be cured, and it does not harm others. There is no danger from a person infected with Inactive TB. Since there are no symptoms, this type of TB is very hard to catch. It can be diagnosed by the Skin test and Blood test.

Active TB

This type of TB shows symptoms and it is contagious as well. When a person infected with this disease sneezes or coughs or talks, the air is polluted with the bacteria. The person who inhales such bacteria polluted air has a high risk of getting infected. If the person inhaling the air has a weak immune system, then he can be affected. The infected person should avoid meeting people and carry treatment in a hospital.

If the injection site is found with red bumps or swelling after 2-3 days, then the person is likely to be infected by Tuberculosis. It is not always 100% true. It can give false results as well.

TB blood test (IGRA test)

The blood test can indicate the presence of Tuberculosis bacteria. Its result is better than the skin test, it is not 100% correct as well. Although it is less likely to give a false result.

Chest X-ray

Tuberculosis mostly affects the lungs, so it can be diagnosed by Chest X-ray. The infected lungs can be seen in the X-ray result.
