Which of the following is NOT considered a bloodborne pathogen?

The choice that is not considered a bloodborne pathogen is indeed Streptococcus. Bloodborne pathogens are generally defined as infectious microorganisms in human blood that can cause disease in humans. This includes viruses and certain bacteria that are transmitted through blood or other potentially infectious materials.

Hepatitis B Virus, HIV, and Hepatitis C Virus are all classified as bloodborne pathogens because they can be transmitted through contact with infected blood. They pose significant health risks, including the potential for chronic infections and serious diseases, such as liver disease and AIDS.

Streptococcus, while it can cause various infections (such as strep throat, pneumonia, and skin infections), is primarily known for being transmitted through respiratory droplets and contact with infected surfaces or individuals rather than through blood. Therefore, it does not fit the definition of a bloodborne pathogen.
