Which of the following statements about HIV transmission is correct?

HIV can indeed be transmitted through blood, which is a key transmission route for the virus. This includes exposure to infected blood via various means, such as sharing needles, needle-stick injuries in healthcare settings, or blood transfusions (although the latter is rare in places where blood screening is practiced). Blood is one of the primary bodily fluids through which HIV spreads, alongside others like semen, vaginal fluids, and breast milk.

The fact that HIV can be present in blood is crucial for understanding how the virus is transmitted and the necessary precautions that should be taken to prevent its spread, especially in settings where blood exposure is possible. Recognizing these modes of transmission is vital for both educational and practical purposes in healthcare and community settings.
