Tuberculosis

4-minute read

Tuberculosis (TB) is an infectious disease that damages people’s lungs or other parts of the body and can cause serious illness and death. TB is caused by the bacterium (germ) Mycobacterium tuberculosis.

The difference between active and latent TB disease

People infected with TB bacteria may not get sick because their bodies are able to fight off the infection. This is called latent or inactive TB, and is not infectious.

People who are infected with the TB bacteria that multiplies and grows and the immune system is not able to fight off the bacteria are said to have active TB. These people will have symptoms and are infectious.

How tuberculosis is spread

TB is spread through the air when a person with active TB disease spreads the bacteria by coughing, sneezing, shouting, speaking or singing and other people nearby breathe in the bacteria.

High-risk groups of tuberculosis

You are most at risk if you:

  • have been recently infected with TB bacteria, including people who work close to someone with active TB, who live in countries where there is a lot of TB, and young children
  • have a medical condition that weakens your immune system, like HIV or AIDS, diabetes and some cancers

Tuberculosis symptoms

People with TB can:

  • feel tired and unwell
  • have a bad cough that lasts at least 3 weeks
  • lose weight
  • have a fever and sweat in bed at night
  • cough up blood in the sputum (phlegm)
  • have chest pains
  • have swollen lymph glands

Tuberculosis diagnosis

Your doctor may order TB skin and blood tests, sputum tests and chest x-rays.

The results of the tests can take a long time — 6 weeks or more — to come back.

Tuberculosis treatment

For latent TB your doctor can prescribe tablets to reduce the risk of you developing active TB.

For active TB, you will be prescribed a combination of special antibiotics, which you must take for at least 6 months.

You may need initial treatment in hospital. If you complete the full treatment, you can be cured of TB disease.

Because TB is a notifiable disease, doctors must report all cases to the health authorities.

Precautions for tuberculosis patients

  • Finish the full course of all TB medicines or you could become seriously ill or die.
  • Cover your mouth when coughing or sneezing.
  • Ask family and close contacts to visit their doctor or clinic for TB tests.

Tuberculosis prevention

There is a vaccination against tuberculosis, but it’s not recommended for everyone. The vaccine registered for use in Australia has not been available for some time. Alternative unregistered vaccines may be available through special prescribing arrangements.

It is recommended for Aboriginal and Torres Strait Islander babies living in some parts of Australia, children who are travelling to parts of the world where there is tuberculosis, and young children who are exposed to leprosy at home. Everybody is recommended to have a skin test before they are vaccinated.

Tuberculosis vaccine

Vaccination is your best protection against tuberculosis. This table explains how the vaccine is given, who should get it, and whether it is on the National Immunisation Program Schedule. Some diseases can be prevented with different vaccines, so talk to your doctor about which one is appropriate for you.

What age is it recommended? Babies under 12 months.
When to get vaccinated? Vaccination should be given 3 months before travel to an area with tuberculosis.
How many doses are required? One
How is it administered? Injection
Is it free?

Find out more on the Department of Health website and the National Immunisation Program Schedule, and ask your doctor if you are eligible for additional free vaccines based on your situation or location.

Common side effects The vaccine is safe. After the vaccination, a small, red sore forms and then ulcerates and heals. There can be a scar. Lymph nodes can get swollen.
