It is important to know the ways exposure and transmission are most likely to occur in your particular situation, be it providing first aid to a student in the classroom, handling blood samples in the laboratory, or cleaning up blood from a hallway. Contact between broken or damaged skin and infected body fluids Contact between mucous membranes and infected body fluids Accidental puncture from contaminated needles and other sharps can result in transmission of bloodborne pathogens. For example, if someone infected with HBV cut their finger on a piece of glass, and then you cut yourself on the now infected piece of glass, it is possible that you could contract the disease.
Unbroken skin forms an impervious barrier against bloodborne pathogens.
Acne Any sort of damaged or broken skin such as sunburn or blisters Bloodborne pathogens may also be transmitted through the mucous membranes of the Eyes Nose Mouth For example, a splash of contaminated blood to your eye, nose, or mouth could result in transmission.
