Which virus can be present for many years without symptoms, according to the CDC?

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

Answer: (A)

HIV infection often remains asymptomatic for many years, which is why it can be present in the body without symptoms for a long time. This long asymptomatic period means someone can be infected and still feel healthy, yet still potentially transmit the virus through blood or other bodily fluids if precautions aren’t taken. In salon safety, this highlights why universal precautions are essential: treat all blood and fluids as potentially infectious, wear gloves, and properly sterilize implements to prevent transmission.

AIDS is not a virus itself; it’s the advanced stage of HIV infection. Hepatitis A typically causes an acute illness that doesn’t become chronic, and Hepatitis B can become chronic but is not the classic example of long asymptomatic carriage highlighted by the CDC.
