Quick Answer
AIDS, the most advanced stage of HIV infection, began after the simian immunodeficiency virus (SIV) jumped from chimpanzees to humans in Central Africa, likely in the early 1900s. HIV gradually spread worldwide, and without treatment it destroys immune cells, leading to AIDS. Today, modern antiretroviral therapy allows people to reach undetectable viral loads, preventing progression to AIDS.
- HIV likely originated from SIV in chimpanzees in Central Africa.
- The virus crossed to humans through hunting or handling infected meat.
- HIV destroys CD4 immune cells; AIDS is the final stage of infection.
- Weight loss in HIV can begin during acute infection or later stages.
- Modern treatment can lower viral load to undetectable levels.
- Undetectable viral load means the virus cannot be transmitted to others.

Understanding how AIDS began requires looking at the origins of HIV, the virus that causes it. HIV is a retrovirus that primarily targets the immune system. Without treatment, the infection gradually weakens the body’s defenses until it reaches the stage called AIDS. Many people also ask about weight loss linked to HIV, which can occur at different points. This guide explains the origins, the distinction between HIV and AIDS, and what modern treatment means for people living with HIV.
Frequently Asked Questions
When does hiv weight loss begin?
Timelines vary by infection. Bacterial STIs like chlamydia and gonorrhea show up on NAAT tests within 1–2 weeks, syphilis needs 3–6 weeks, HIV appears on modern lab tests within 18–45 days, and reliable herpes blood tests wait 12–16 weeks.

How much weight loss in hiv?
Public clinics often charge $0–$50, direct-to-lab panels run roughly $75–$250, urgent care adds a visit fee, at-home kits cost $50–$200, and ER visits can exceed $500–$3,000. Sliding-scale clinics keep costs low if money is tight.
