HIV and Pulmonary Tuberculosis: Risks, Symptoms, and What to Do

People with HIV have a much higher risk of developing active pulmonary tuberculosis (TB). When HIV lowers immunity, the body can’t keep TB bacteria in check, so a latent TB infection can become active. If you or someone you care for has HIV, knowing the signs and steps to take can make a big difference.

How does HIV change TB risk? HIV attacks CD4 cells, and fewer CD4 cells mean weaker defenses in the lungs. This raises the chance that exposure to TB will lead to disease and increases the risk that a dormant TB infection will reactivate. Treatment for HIV helps, but TB screening and prevention remain crucial.

Common symptoms to watch for

Persistent cough lasting more than two weeks, often with sputum or blood, is a key red flag. Other common signs include fever, night sweats, unintentional weight loss, and feeling tired all the time. People with HIV may show less obvious lung signs, so general symptoms like fever or weight loss should prompt testing if TB exposure is possible.

What to do if you suspect TB

Get tested quickly. Tests include a chest X-ray, sputum tests, and molecular tests that detect TB bacteria fast. For people with HIV, doctors often order both TB and HIV tests at the same time, because knowing both infections helps guide treatment safely and effectively.

Treatment usually involves a combination of antibiotics taken for several months. For someone with HIV, doctors coordinate TB drugs and antiretroviral therapy to reduce interactions and side effects. Taking all medicines exactly as prescribed is vital to prevent resistance and improve recovery.

Prevention matters. If you have HIV, ask your provider about preventive TB therapy if you test positive for latent TB. Vaccination with BCG is not usually helpful for adults with HIV in places where TB risk is high, so follow local health advice. Simple steps like avoiding crowded, poorly ventilated places when TB is known in the community also help.

Support and follow-up are part of care. TB treatment can be hard on the body and mind, so check in with healthcare teams about side effects, drug interactions, and adherence help. Community programs and support groups often provide practical advice, reminders, and emotional support during treatment.

Published research shows that integrating HIV and TB services increases diagnosis and improves outcomes. Programs that test, treat, and follow patients for both infections reduce deaths and stop more spread of TB.

Routine screening is wise: get tested at diagnosis, before starting ART, and periodically if you live or work where TB is common. Tell close contacts if youre diagnosed so they can be tested. Health workers can help arrange contact tracing, which speeds care and reduces further spread. Ask your clinic for resources.

If you have questions about testing, treatment options, or local services for HIV and TB, contact your healthcare provider or local public health clinic. Quick action saves lives and helps protect those around you.
