Hospital workers are exposed to various infectious diseases, including viruses, bacteria, and fungi. Working closely with sick patients puts them at risk of contracting these illnesses. Common exposure scenarios include:nBloodborne pathogens: Hospital workers who come into contact with blood or bodily fluids are more vulnerable to contracting diseases like HIV, hepatitis B, and hepatitis C.nnAirborne infections: Respiratory illnesses like influenza, tuberculosis, and COVID-19 can spread through the air, putting healthcare workers at risk. This is more likely in high-traffic areas like emergency departments and intensive care units.nnContact transmission: Skin-to-skin contact or touching contaminated surfaces can transmit infections like methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile (C. diff).
