About HIV
Comprehensive information about HIV, including what it is, how it spreads, who is at risk, symptoms, stages, and the latest treatment options.
KEY POINTS
- •HIV is a virus that attacks the immune system; without treatment, it can lead to AIDS.
- •Modern antiretroviral therapy (ART) allows people with HIV to live long, healthy lives.
- •An undetectable viral load means HIV cannot be transmitted through sex (U=U).
- •Early diagnosis and treatment are critical for health and prevention.
- •Regular testing is the only way to know your HIV status.
Understanding HIV
HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system. It targets CD4 cells (T cells), which are crucial for fighting infections and diseases. Without treatment, HIV can progressively weaken the immune system, eventually leading to AIDS (Acquired Immunodeficiency Syndrome).
However, with modern antiretroviral therapy (ART), people with HIV can achieve an undetectable viral load, allowing them to live long, healthy lives and prevent transmission to others. This breakthrough is known as U=U (Undetectable = Untransmittable).
