Posttraumatic stress disorder after occupational HIV exposure: two cases and a literature review.

Two healthcare workers developed disabling chronic posttraumatic stress disorder after needlestick exposures to blood from a patient infected with human immunodeficiency virus (HIV), even though both continue to test negative for HIV antibody more than 22 months after their exposures. We describe these 2 cases and review the relevant literature. Prospective studies of psychological morbidity after occupational needlestick injuries are required to determine the role of long-term psychological follow-up, counseling, and support.
