title: Lack of transmission of hepatitis B after surgical exposure.
abstract: An orthopedic surgeon in whom hepatitis B subsequently developed participated in operations on 49 patients in the two months preceding his illness. Thirty of these patients were available for subsequent clinical and serologic follow-up: five had positive reactions for antibody to hepatitis B surface antigen (anti-HBs) and one had a positive reaction for hepatitis B surface antigen (HBsAg) at the initial examination an average of 77 days after surgery. No new patients had either clinical or serologic evidence of hepatitis B during four months of subsequent follow-up (mean of 6.7 months after surgery). A control group of 56 orthopedic patients had a 25% prevalence of positive reactions for anti-HBs and negative reactions for HBsAg- this was not significantly different from the exposed group. The risk to patients of acquiring hepatitis B after surgical exposure in this setting from a surgeon is low.
