When can a person be infected with a bloodborne pathogen based on the modes of transmission?

A person can be infected with a bloodborne pathogen through exposure to mucous membranes because these membranes, which include the lining of the mouth, nose, and eyes, are highly permeable and can allow pathogens to enter the bloodstream. Bloodborne pathogens, such as HIV, Hepatitis B, and Hepatitis C, can easily infect individuals if they come into contact with infected blood or bodily fluids and then enter the body through mucous membranes.

While sexual contact and needle sticks are specific transmission routes, they do not encompass all the ways in which bloodborne pathogens can be transmitted. In addition, exposure to air is not a mode of transmission for these pathogens, as they typically require direct contact with infected blood or fluid for transmission to occur. This emphasizes the importance of practicing safety measures to protect mucous membranes, alongside other precautions, in environments where exposure could occur.
