Someone infected with both HIV and TB is at least 10 times more likely to develop both infections also means you have AIDS, the advanced stage of HIV. Cases of TB have tripled in African countries with a high HIV prevalence since , according to a report released by the World Health.

HIV attacks the body's immune system. This means HIV has entered your bloodstream. How is HIV transmitted? HIV is found in body fluids such as blood, semen and vaginal fluids, and breast milk. HIV infection can only occur when one or more of these body fluids from an infected person enters the bloodstream of another person. HIV is only transmitted in the following ways: What are the symptoms of HIV?

You can't tell just by looking if someone has HIV.

Most people who have HIV look healthy and have no symptoms. It may take several years before any symptoms begin to show and many people who have HIV don't know it themselves.

If it is not treated, HIV damages the immune system so that it is no longer able to fight off common infections and the person is at risk of illness and even death.

If you have HIV it means you: If these two infections are not treated, they can work together to cause very serious illness. What tests do I need to do for TB? The decision about which tests are needed will be made by the chest clinic. What tests do I need to do for HIV? What is the cost? You may need an appointment to attend a chest clinic but you do not need a Medicare card. It is also available at your local doctor but you need a Medicare card. TB can be diagnosed by injecting a protein found in TB bacteria into the skin of an arm.

If the skin reacts by swelling then the person is probably infected with TB.

However, this method is not wholly reliable at detecting TB infections among HIV-infected people because their weakened immune systems often cannot mount a strong enough defence against the injected proteins to cause swelling.

It also detects both active and latent TB, meaning the test is not very accurate at diagnosing active TB disease in people who live in areas where TB and thus latent TB infection is very common. In cases of extra-pulmonary TB where the disease is affecting organs other than the lungsfluid or tissue samples may be tested. If there is doubt about the diagnosis of TB, a culture of TB bacteria can also be grown in a laboratory. However, this requires specialised and costly equipment and can take six to eight weeks to produce a result.

If the necessary facilities are not available then the TB diagnosis is often based on symptoms. How is TB treated? Active TB disease can almost always be cured with a combination of antibiotics. The variety of treatments and drug options depend on the country you are in. A proper combination of anti-TB drugs provides both prevention and cure. Effective treatment quickly makes the person with TB non-contagious and therefore prevents further spread of TB.

Achieving a cure takes about six to eight months of daily treatment. Several drugs are needed to treat active TB. Taking several drugs does a better job of killing all of the bacteria and is more likely to prevent them from becoming resistant to the drugs.

To ensure thorough treatment, it is often recommended that the patient takes his or her pills in the presence of someone who can supervise the therapy. This approach is called DOTS directly observed treatment, short course. Can TB be prevented?

HIV/TB Co-infection

There is a vaccine against TB called BCG, but the vaccine is now very old it was first used in the sand tests have found it to be very variable in its ability to protect people from infection in modern settings. If there is a reaction, the size of the reaction is measured to determine if you have a positive result.

If you receive the TB blood test, a sample of your blood will be taken to do the test. Your health care worker will tell you how to get the results of your test. What if my TB test is negative? A negative test usually means you are not infected with TB germs. However, the tests may be falsely negative if you have a weakened immune system or if you were infected recently.

This is because it usually takes 2 to 8 weeks after exposure to a person with TB disease for your immune system to produce a response to the test. If you have a negative result and it has been less than 8 weeks since you were last exposed to TB disease, you may need to get a second test. Your health care worker will let you know if you need another test. Some people with HIV infection will have a negative test result even if they are infected with TB germs.

This is because the immune system, which causes the reaction to the tests, is not working properly. What if my TB test is positive?

It does not mean that you have TB disease. Other tests, such as a chest x-ray or sputum phlegm sample, are needed to see if you have developed TB disease. You will need treatment for latent TB infection as soon as possible to prevent TB disease.
