[BDSP. Notice produite par INIST tYWY5R0x. Diffusion soumise à autorisation]. The recent licensing of active hepatitis A vaccines raises the question of vaccine candidates. Although various groups of workers are at theoretical occupational risk of hepatitis A infection, no comprehensive quantitative data exist to determine which occupational groups should receive active vaccination. Therefore, the aims of this study were to identify occupations at risk for hepatitis A infection and to determine their relative risk. In this nationwide historical prospective study, the relative risk of hepatitis A among different occupations in Israel was determined according to the incidence of hepatitis A in different occupations during 1993 and 1994 compared with the incidence of hepatitis A in two standard populations. After age, gender, ethnicity, and time of immigration to Israel were controlled for, certain occupations showed a significant increased risk of hepatitis A : yeshiva students (standardized incidence ratio (SIR)=9.98,99% confidence interval : 7.55,13.18), day care center and kindergarten staff (SIR=5.47,99% confidence interval : 3.50,8.57), food industry workers (SIR=5.41,99% confidence interval : 1.92,15.25), teachers (SIR=4.02,99% confidence interval : 2.92,5.48), physicians and dentists (SIR=3.77,99% confidence interval : 1.78,8.14), and therapists and medical technicians (SIR=3.75,99% confidence interval : 1.75,8.14). Sewage workers and nurses did not show any significantly increased risk. (...)
