what is Tuberculosis?


Tuberculosis is a disease caused by bacteria that attack the lungs. It is a serious health problem, especially in developing countries. Tuberculosis is spread through the air, and can be fatal if not treated properly. Early diagnosis and treatment are essential to prevent the spread of tuberculosis.

How does tuberculosis spread?

Tuberculosis is spread through the air from person to person. When a person with TB or throat coughs, talks or sings, they push TB germs into the air. A person only needs to inhale a few of these to become infected.

How can I prevent myself from contracting tuberculosis?

There are several things you can do to prevent tuberculosis:

Get the tuberculosis vaccine. This is only recommended for people at high risk of coming into contact with bacteria, such as health care workers.

Avoid close contact with people with active tuberculosis.

If you have to be around someone with tuberculosis, make sure they wear a mask and stay in a well-ventilated area.

Practice good hygiene, such as washing your hands frequently and coughing into your sleeve.

What are the symptoms of tuberculosis?

Tuberculosis (TB) is an infection caused by bacteria called Mycobacterium tuberculosis.. The symptoms of tuberculosis depend on the location of the infection in the body.

If TB bacteria are in the lungs, they may cause:

Cough and cough that may last for three weeks.

  • pain in chest
    Weakness or tiredness
  • Weight loss
  • lack of appetite
    Chills and fever
    Night sweats
  • If TB bacteria are present in other parts of the body, such as the kidneys, spine, or brain, they may cause:
  • Back ache
  • Headache
  • Weakness or numbness in the legs
  • seizures
  • vision problems
  • Memory problems
  • Changes in behavior

How is tuberculosis treated?

Treatment for tuberculosis (TB) must be carefully monitored because the bacteria that cause tuberculosis can develop resistance to the drugs used to treat it. This resistance can make tuberculosis more difficult to treat.

The standard treatment for tuberculosis is a combination of four drugs given for six months. These drugs are isoniazid, rifampin, pyrazinamide, and ethambutol. Your doctor will likely prescribe other medications as well, such as pain relievers, to reduce the side effects of TB medications.

Even if you start to feel better, you will need to take your TB medicines exactly as prescribed and complete the full course of treatment. If you stop taking your medications too soon, the TB bacteria can become resistant to the drugs and become more difficult to treat.

What are the treatments for tuberculosis?

The most common treatment for tuberculosis is a combination of four drugs: isoniazid, rifampicin, pyrazinamide and ethambutol. These medications are usually taken for six to nine months. If the TB bacteria are resistant to one or more of these medicines, other medicines may be used instead.

In some cases, it may be possible to take only two drugs (isoniazid and rifampicin) for six months. This is called a short-term treatment and is only an option if you have a very low risk of TB bacteria becoming drug-resistant.

If you have tuberculosis, you will need to take the medications for at least six months. If you have latent tuberculosis infection, you will need to take the medications for at least three months.

What do I do if I think I have tuberculosis?

If you think you have tuberculosis (TB), it is important to see a doctor as soon as possible. Tuberculosis is a serious infection that can be fatal if not treated properly.

Your doctor will likely ask you about your symptoms and medical history, and may order one or more tests to confirm the diagnosis. This may include a chest X-ray, skin test, and/or a blood test.

If you are diagnosed with tuberculosis, you will need to take medications for several months to kill the bacteria and prevent the infection from spreading. You will also need to avoid close contact with other people during this time to prevent them from getting infected.
