Which is true about HIV?

• A. It can be in a person's blood before it causes health problems
• B. It can be cured with antibiotics
• C. It is transmitted only through blood transfusions
• D. It cannot be detected in blood

Answer: (A)

HIV can be present in the blood long before health problems appear. The virus may replicate and gradually weaken the immune system while a person feels fine, so someone can test positive before any symptoms show. Modern testing can detect HIV early, using methods that look for the virus itself or for the body's immune response after seroconversion. This is why presence in blood does not always coincide with illness yet. Antibiotics don’t cure HIV because they target bacteria, not viruses; HIV is managed with antiretroviral therapy to control the virus, but it isn’t curable with antibiotics. HIV isn’t transmitted only through blood transfusions; it can spread through unprotected sex, sharing needles, and from mother to child, among other routes, although blood screening has reduced transfusion-related risk. And yes, HIV can be detected in blood with the appropriate tests.
