Which of the following diseases is classified under Bloodborne pathogens?

The disease classified under Bloodborne pathogens is HIV. Bloodborne pathogens are infectious microorganisms present in blood that can lead to diseases in humans. HIV (Human Immunodeficiency Virus) is specifically transmitted through blood, semen, vaginal fluids, and breast milk, making it a prime example of a bloodborne pathogen.

In contrast, diseases like measles, tuberculosis, and chickenpox are spread through different routes, primarily respiratory droplets or airborne transmission, rather than through exposure to infected blood. Therefore, understanding the transmission methods is crucial in identifying bloodborne pathogens accurately, highlighting why HIV is the correct choice in this context.
