Final answer:
Healthcare workers are more at risk for developing nosocomial and opportunistic infections such as MRSA due to exposure to pathogens in healthcare environments and interactions with patients who have weakened immune systems.
Step-by-step explanation:
Healthcare workers are at increased risk for developing certain types of infections due to their exposure to pathogens and the nature of their work. These include nosocomial and opportunistic infections. Nosocomial, or hospital-acquired infections, occur in healthcare settings and can be transmitted through contaminated medical equipment or surfaces, or by healthcare providers themselves if hand hygiene and other infection control precautions are not adequately practiced. Opportunistic infections are those that occur more frequently or are more severe in individuals with weakened immune systems, as is often the case with hospital patients. Examples of such infections include those caused by methicillin-resistant Staphylococcus aureus (MRSA), which is highly resistant to many commonly used antibiotics, leading to challenging and potentially severe infections.
