HIV/AIDS: What You Need to Know Right Now

More than 38 million people live with HIV worldwide, and treatment has changed the game: people on effective medicine can live long, healthy lives and won’t sexually transmit the virus. If you’re worried about exposure, testing, or meds, here’s practical, no-nonsense info you can use today.

Fast steps: testing, prevention, and immediate actions

Worrying about a possible exposure? Get tested. Quick options include rapid antibody tests (results in 20–30 minutes) and lab-based tests that check viral RNA. If the exposure was recent — within 72 hours — ask a clinician about PEP (post-exposure prophylaxis). PEP is a short course of medicines that can prevent infection if started fast.

For ongoing prevention, PrEP (pre-exposure prophylaxis) is a daily pill or newer injectable options that can cut sexual transmission risk by roughly 99% when used as directed. PrEP is for people at higher risk or those in serodiscordant relationships. Talk to a provider about which form fits your life.

Living with HIV: treatment, adherence, and what “undetectable” means

Antiretroviral therapy (ART) suppresses the virus. Most modern regimens are one pill a day or a periodic injection. The goal is an undetectable viral load. Undetectable means the virus is so low it can’t be measured — and that equals untransmittable sexually (U=U). That’s huge for relationships and mental health.

Side effects happen but are usually manageable: nausea, fatigue, or changes in sleep or appetite at first. Consistent dosing matters more than anything — skipping doses raises the chance of resistance. If cost or access is an issue, local clinics, government programs, and some online pharmacies offer discounts or patient assistance. Always use a legitimate pharmacy and keep prescriptions from a licensed provider.

Drug interactions matter. Tell your clinician about other meds and supplements you take — some antacids, herbal supplements, or seizure drugs can change how well ART works. If you're ordering meds online, verify the pharmacy’s credentials, require a prescription, and check reviews. Avoid sites that sell controlled meds without asking for a prescription.

Living with HIV isn’t just medical. Mental health support, peer groups, and practical help with housing or work make a big difference. Many clinics pair medical care with counseling and social services. If you’re newly diagnosed, ask about a case manager — they help arrange tests, meds, and follow-up.

If you want specific next steps: get tested at a local clinic or with an approved home test; if exposure was recent, seek PEP now; if you’re at ongoing risk, ask about PrEP; and if you’re living with HIV, stick with ART and stay in care.
