BACKGROUND: Infectious diseases represent a major component of biological hazards encountered by healthcare workers. Occupational exposure may occur through multiple transmission pathways including airborne particles, direct contact, contaminated environments, or blood exposure accidents. Understanding these mechanisms is essential to guide effective prevention strategies in healthcare settings.
METHODS: This narrative review synthesises current epidemiological data and preventive recommendations regarding occupational infectious risks in healthcare and related professional environments. Major pathogens and transmission mechanisms were analysed using recent literature and public health guidance.
RESULTS: Healthcare workers may be exposed to a wide spectrum of infectious agents including respiratory viruses (influenza, measles, tuberculosis), contact transmitted pathogens (scabies, cytomegalovirus), enteric infections (hepatitis A), and blood borne viruses such as hepatitis B, hepatitis C, and human immunodeficiency virus. Transmission risk depends on the interaction between an infectious source, transmission route, and host susceptibility. Occupational exposure varies according to professional activities, patient populations, and environmental conditions. Although some infections such as measles or influenza show increased incidence among healthcare workers, improved infection control measures have substantially reduced risks associated with blood exposure accidents and other occupational exposures. Preventive strategies rely on a combination of measures including vaccination, standard precautions, hand hygiene, appropriate use of personal protective equipment, environmental control, and rapid management of exposure incidents.
CONCLUSION: Infectious risks remain a significant occupational concern for healthcare workers. However, adherence to comprehensive prevention strategies-particularly vaccination, hygiene measures, and appropriate protective equipment-substantially reduces transmission risk in healthcare environments.
