Occupational infection with human immunodeficiency virus (HIV). Risks and risk reduction

Area of Science:

• Occupational health
• Infectious disease epidemiology
• Public health

Background:

• The expanding acquired immunodeficiency syndrome (AIDS) epidemic increases the prevalence of human immunodeficiency virus (HIV) in healthcare settings.
• Healthcare workers (HCWs) face potential occupational exposure to HIV.

Purpose of the Study:

• To address occupational HIV infection among healthcare workers.
• To evaluate risks and prevention strategies for HIV exposure in healthcare environments.

Main Methods:

• Discussion and consensus-building among symposium participants at the Fifth Annual Advances in Occupational Cancer Conference.
• Review of current standards for blood/body fluid precautions and hospital waste disposal.

Main Results:

• The risk of occupational HIV infection for HCWs is considered low, though not zero.
• Universal blood and body fluid precautions are effective in preventing HIV exposure, particularly needlestick injuries.
• Existing hospital waste disposal standards are adequate for preventing HIV transmission.

Conclusions:

• Universal precautions are essential for preventing occupational HIV exposure in healthcare settings.
• Confidential HIV antibody testing and counseling are recommended for HCWs when indicated.
• Occupational risk does not negate HCWs' responsibility to care for patients with HIV.
