HBV, HCV, or HIV infection examples of which type of disease?

• A. Blood-Borne Disease
• B. Chronic Infection
• C. Communicable Disease
• D. Direct Contact

Answer: (A)

These infections are defined by how they spread: through blood. Hepatitis B and C, and HIV are primarily transmitted when infected blood or certain bodily fluids come into contact with another person, such as through sharing needles, unsafe injections, contaminated blood products, or needlestick injuries in healthcare settings. Because the question focuses on the route of transmission, categorizing them as blood-borne diseases highlights the main way they’re spread and the precautions needed to prevent transmission (like safe needle practices and proper handling of blood). They can be chronic and are certainly communicable, but those traits don’t specify the transmission route as clearly as the blood-borne aspect does. Direct contact covers a broader range of transmission modes that aren’t specific to blood exposure, so it doesn’t pinpoint the characteristic feature these infections share.
