What is tuberculosis(TB)?
Tuberculosis (TB) is an airborne bacterial infection caused by the organism Mycobacterium tuberculosis, which affects many organs of the body, such as body tissues, and especially the lungs. Tuberculosis transmitted through the air from one person to another. When a person suffering from TB in the lungs or throat sneezes, laughs, sings or talks, the germs that cause TB can spread to other people through the air. If another person breathes air infected with these germs, then that person may also be infected with tuberculosis.
Key points… you should know
- No one can easily become infected with tuberculosis.
- Most infected people have latent TB, which means they have tuberculosis in their body. But their immune system protects them from getting sick and they are not contagious.
- If you take the medicine according to the correct prescription of the doctor, TB can be completely cured.
Types of Tuberculosis
There are mainly two types of TB. Latent TB infection and Active TB disease. It is important to understand that there is a difference between getting infected with TB (latent TB) and active TB disease.
Latent TB infection
When a person infected with TB has TB pesticide or bacteria in his body, but even after that, if he is not getting sick, then it is called latent TB. Because in such a situation the person’s immune system protects him from TB germs and prevents him from getting sick.
Active TB disease
A person with TB infection is getting sick and the disease is spreading to others. This means that the person is suffering from active TB disease. A person with TB disease should see a doctor as soon as possible and take the full prescription.
It is a very rare type of active TB when TB bacteria enter your body’s bloodstream. In this form of TB, bacteria spread very quickly throughout the body and affect one or more organs at the time.
Can anyone get infected with TB?
No person can easily become infected with tuberculosis. Generally, a person has to stay close to a person with TB disease for a long time. TB is usually spread among family members, close friends, and people who work together or live together. Chances of TB outbreak are high in closed places and most easily spread in closed places.
People with a weakened immune system (for example, people with HIV / AIDS who receive chemotherapy, or children under 5), are at greater risk for developing TB disease. When they breathe air infected with TB bacteria, the bacteria settle in their lungs and begin to grow because their immune system cannot fight the bacteria. In these people, TB disease can develop within a few days or weeks of infection.
Other people who have latent TB infection in their body may not develop for months or years if they become healthy and their immune system can fight the infection. But with time if their immune system is weakened due to any other reason then they will not be able to fight TB germs (Mycobacteria) and can become infected with active TB.
How Tuberculosis (TB) Affects Your Body?
When a person has tuberculosis (TB) disease. So this means that TB bacteria is spreading and attacking the lungs (body) or other parts of the body, such as lymph nodes, bones, kidneys, brain, spine, and even the skin. From the lungs, TB bacteria spread to different parts of the body through the blood or lymphatic system. Symptoms of active TB disease include cough, loss of weight, loss of appetite, fever, chills and night sweats, as well as the failure of a specific organ or system to function properly. For example, if tuberculosis bacteria attack the bones, you may experience the following symptoms such as cough due to tuberculosis, coughing in the lungs or bone pain.
How severe is tuberculosis (TB)?
In some people, tuberculosis can cause coughing, chest pain, and bloody mucus. If it is not treated properly in time, it can increase and even be fatal.
Despite the popular misconception that tuberculosis (TB) is a disease of the past, it remains a significant threat to global public health. About one-fourth of the world’s population, are infected with tuberculosis. Most infected people have latent TB, which means they have tuberculosis in their body, but their immune system has kept them from getting sick. However, around 10 million people worldwide have TB disease. In the United States, TB is very less common, however, it causes uneven illness in some populations.
