What is the difference between latent TB infection and TB disease? People who are infected, but are not sick, have what is called latent TB infection. People with latent TB infection have TB germs in their body, but they are not sick because the germs lie dormant sleeping in their body. People with latent TB infection do not have symptoms and cannot spread the germs to others. To prevent developing TB disease, people with latent TB infection can take medicine. They usually have one or more of the symptoms of TB disease.
People with TB disease often feel weak or sick, lose weight, have fever, and have night sweats. If TB disease is in their lungs, they may also cough and have chest pain, and they might cough up blood. Other symptoms depend on what part of the body is affected by the TB germs.
People with TB disease may spread TB germs to others.
TB disease needs to be treated with medicine. The good news is that latent TB infection and TB disease can be treated.
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.

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.
Tuberculosis: The Connection between TB and HIV
Can TB be prevented? 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. When it does provide protection, this generally only lasts for around 15 years. This is often fatal.
A drug called isoniazid INH can be used as a preventative therapy for those who are at high risk of becoming infected with TB or for those who have inactive TB. People who have inactive TB but are not yet sick can take a course of isoniazid for several months to stop them developing active TB. This will cure them and prevent transmission to others. It is important that the TB treatment is taken regularly and exactly as the health care provider has advised.
If the drugs are not taken regularly, the bacteria can become resistant to the drugs and this can be dangerous. This is why access to antiretroviral treatment is also vitally important. Drug resistance usually arises when TB patients do not or cannot take their medicine as prescribed, and drug-resistant mutations of the TB bacteria are allowed to replicate. MDR-TB is a serious problem and is very difficult to treat.
In normal first-line treatment, patients take the drugs isoniazid and rifampicin the most effective TB drug available plus two or three other first-line drugs for around six to eight months. If a person is resistant to isoniazid and rifampicin however, they are said to have MDR- TB, and will need to change to a regime containing newer and often less widely-available "second-line" drugs.
