A person can be infected with ______ for many years without having symptoms, according to the Centers for Disease Control and Prevention.

• A. AIDS
• B. Hepatitis A
• C. HIV
• D. Hepatitis B

Answer: (C)

HIV is able to remain in the body for many years without producing noticeable symptoms, which is why you may hear that someone can be infected for a long time before any signs appear. The CDC emphasizes that many people don’t know they’re infected because symptoms can be absent for years, even though the virus can still be transmitted during this time. This distinction matters because HIV is a virus that can persist in the body for a long period before progressing to more serious illness if untreated.

AIDS, by contrast, is the advanced stage of HIV infection, not a separate infection people carry for years without symptoms. It represents a level of immune system damage rather than a standalone infectious state. Hepatitis A is typically an acute infection with a finite course and doesn’t usually linger asymptomatically for years. Hepatitis B can become chronic, but the scenario described—years of infection without symptoms—fits HIV best, since it is renowned for a long asymptomatic period.

In practical terms for salon safety, this underscores why universal precautions matter: treat all blood and body fluids as potentially infectious and follow proper infection-control practices, since someone may be HIV-positive without knowing it.
