Which of the following is NOT one of the main ways to become infected with a bloodborne pathogen?

Becoming infected with a bloodborne pathogen typically occurs through direct exposure to infected blood or certain body fluids. The primary modes of transmission include methods such as injection, which involves introducing pathogens directly into the bloodstream, and skin abrasions, where breaks in the skin can allow for pathogen entry. Additionally, exposure to mucous membranes, such as the eyes, nose, or mouth, can occur if these membranes come into contact with infectious materials.

Contaminated air does not serve as a pathway for bloodborne pathogens; these pathogens primarily require direct blood-to-blood contact or fluid exchange to transmit diseases like hepatitis or HIV. The pathogens are not transmitted through the air in the same manner as some airborne viruses such as influenza or COVID-19. Thus, the correct answer highlights that exposure to contaminated air is not a recognized route for infection with bloodborne pathogens.
