The prevalence of hepatitis B viral markers in Bloemfontein anaesthetists.

ABSTRACT

A study was undertaken to determine whether the 48 anaesthetists in Bloemfontein have a higher rate of exposure to hepatitis B virus than comparable groups and whether active immunisation with hepatitis B surface antigen is necessary. Hepatitis B markers were detected by radio-immunoassay and the results analysed statistically. Hepatitis B markers were found in the sera of 36.17% of the anaesthetists and they had an 8-9 times greater prevalence of markers than employees of the local hospitals. Hence anaesthetists run a larger risk of contracting hepatitis B and its complications. It is recommended that non-immune anaesthetists be immunised.
