Quick Answer
HIV is not curable today, but it is treatable. The virus writes its genetic code into the DNA of long-lived immune cells, creating hidden reservoirs that current drugs cannot reach and the immune system cannot clear. Daily antiretroviral therapy instead suppresses the virus, often to an undetectable level, so the infection becomes a manageable chronic condition rather than a fatal one.
- Modern antiretroviral therapy can drive HIV to undetectable levels, protecting the immune system.
- Sustained undetectable viral load means HIV is not passed through sex, known as U=U.
- HIV is a retrovirus; AIDS describes an advanced stage of untreated infection, not the virus itself.
- A cure is hard because dormant virus hides inside long-lived cells for decades.
- Stopping treatment usually lets the virus rebound within weeks, so therapy is lifelong for most people.
- Periodic viral load and resistance testing show whether a regimen is still working.
The Landscape
The word untreatable gets attached to HIV for a simple reason: no regimen clears it. HIV is a retrovirus, meaning it copies its RNA into DNA and then inserts that DNA into the chromosomes of the cells it infects - mostly CD4 T cells, which coordinate the immune response. Once inserted, the viral code can sit silent for years. Antiretroviral drugs block steps in the viral life cycle, but they cannot delete DNA already woven into a human chromosome, and they cannot kill the resting cells that harbor it. That hidden reservoir, not drug failure, is why HIV is manageable but not yet curable.
Treatment Windows by Infection
Bacterial infections clear with antibiotics measured in days: a single 500 mg intramuscular ceftriaxone dose for gonorrhea (doxycycline is added only if chlamydia has not been ruled out), seven days of doxycycline for chlamydia, penicillin injections for syphilis staged by duration. Viral infections play a longer game — suppressive antivirals for herpes, daily ART driving HIV to undetectable, and 8–12-week antiviral courses curing over 95% of hepatitis C cases.
