The risk of infection with hepatitis B virus in relation to length of hospital employment.
A sero-epidemiological study was carried out on a representative sample of employees of the Hospital Clinico 'San Cecilio' in an attempt to quantify the influence of the time spent working in the hospital on the risk of becoming infected by hepatitis B virus. The results show that the rate of infection by HBV is directly proportional to the length of employment in the hospital, with a probability of infection between 0.6% and 1.4% for each working year.
