Which of the following is a common bloodborne disease?

Hepatitis B is a common bloodborne disease because it is primarily transmitted through contact with infectious body fluids, particularly blood. This virus can lead to chronic liver disease, liver cancer, and other serious health complications. The significance of Hepatitis B in the context of first aid and criminal justice work is substantial, as officers may encounter situations where they could be exposed to blood or bodily fluids, increasing the risk of transmission.

In contrast, Hepatitis A is primarily transmitted via the fecal-oral route, through contaminated food or water, and does not typically involve blood exposure. Influenza is a viral infection spread mainly through respiratory droplets, rather than blood. Pneumonia, while it can be serious, is a lung infection often caused by bacteria or viruses and is not classified as a bloodborne disease. Understanding the transmission routes of these diseases is crucial for providing effective first aid and for ensuring the safety of those who may come into contact with blood or bodily fluids in their line of work.
