Understanding the magnitude of occupational exposure to human immunodeficiency virus (HIV) and uptake of HIV post-exposure prophylaxis among healthcare workers in a rural district in Tanzania

摘要

Background: Occupational exposure to blood or other body fluids in healthcare settings puts healthcare workers (HCWs) at risk of acquiring human immunodeficiency virus (HIV) infection. It is estimated that between 200 and 5000 HIV infections are transmitted annually to HCWs worldwide. Use of post-exposure prophylaxis (PEP) has been documented to reduce the rate of HIV infection from workplace exposures by 81%.
