A person with HIV may be more at risk of developing tuberculosis (TB). This is due to the weakening of the immune system that occurs in someone who has HIV.
Tuberculosis (TB) is a bacterial infection that can spread through the air. TB typically affects the lungs, but it can spread to other parts of the body.
HIV is a virus that can spread from person to person through bodily fluids, causing a weakening of the immune system. A weakened immune system may increase the risk of TB infection.
Read on to learn about the link between HIV and TB. This article also looks at symptoms of TB, when an individual with HIV should get a TB test, TB treatments for someone with HIV, and more.
A person
When an individual has HIV, the immune system becomes weaker. This can make the body less able to fight off infections and bacteria such as TB.
According to the National Institutes of Health (NIH), TB is an opportunistic infection (OI). This means that it is more common and more severe in people with weakened immune systems.
Therefore, a person with HIV may be more likely to develop TB and have more severe symptoms than a someone without HIV.
According to the World Health Organisation (WHO), an individual with HIV may be

Medications for TB in a person with HIV is
However, there may be factors a healthcare professional has to consider when prescribing TB medication to a person with HIV, as it is possible the two treatments can interact and cause further issues.
TB treatment may also require adjustment depending on whether an individual has already started HIV treatment or has developed any resistance to medications.
The type of medication and the duration of treatment can depend on whether a person has latent TB or active TB, as well as whether they experience medication resistance.
Examples of medications for HIV include:
- isoniazid
- rifampin
- pyrazinamide
- ethambutol
