The risk of occupational exposure and infection with infectious disease
1Consultant in Clinical Epidemiology, Microbiology, and Infection Control, Charleston, South Carolina, USA.
Abstract:
The diversity of potentially infectious agents that frequent the health care environment continues to increase. As a result, healthcare workers are at some degree of risk, for exposure to, and infection by, a variety of infectious diseases or conditions. This article is devoted to the epidemiology of major infectious diseases and conditions known to be transmitted in health care settings. In addition, the relative risk of occupational exposure to and infection by these diseases is also discussed as are general preventive measures associated with Standard and Transmission-based Precautions.

Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Standard Precaution
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
