Summary

A seroepidemiological study was carried out in order to determine the prevalence of markers of viral hepatitis infection in employees of five health-care companies and their cohabiting family members. Each participating family unit was required to fill out a questionnaire, in which, among other data, the employee was requested to indicate his or her job category. Markers of hepatitis B infection (anti-HBs, anti-HBc or HBsAg) were observed in 11.7% (58/497) of all subjects. When employees and family members were analysed according to the employee's job category, significant differences were found between “staff” (3%) and “administrative personnel” (13.3%; p<0.01) or “factory workers” (16.9%; p<0.01). Of 489 individuals tested for the presence of anti-HAV and anti- HCV, 59.1% and 0.6% respectively, were positive. There was a correlation between the prevalence of anti-HAV and age; a large proportion of the subjects under the age of 30 years had no evidence of prior HAV infection.

Zusammenfassung

Um die Prävalenz von Virus-Hepatitis-Markern zu ermitteln, wurde eine seroepidemiologische Studie durchgeführt, in die Beschäftigte von fünf pharmazeutischen Firmen und Familienmitglieder der Wohngemeinschaft aufgenommen wurden. Fragebogen, die alle teilnehmenden Familien auszufüllen hatten, enthielten unter anderem Daten zur Berufsbezeichnung. 58 von 497 untersuchten Seren (11,7%) wiesen Marker einer Hepatitis B Virus-Infektion auf (anti-HBs, anti-HBc oder HBsAg). Nach Berufskategorie aufgeschlüsselt, fanden sich zwischen Beschäftigten und Familienmitgliedern signifikante Unterschiede: Personen, die zum Staff gehörten, waren in 3% der Fälle positiv, Verwaltungspersonal in 13,3% (p<0,01), Fabrikarbeiter in 16,9% (p<0,01). Von den 489 auf anti- HAV getesteten Personen waren 59,1 % positiv, anti-HCV-Antikörper wiesen in derselben Gruppe 0,6% der Getesteten auf. Die Prävalenz von anti-HAV zeigte eine Altersabhängigkeit; ein großer Anteil der unter 30jährigen hatte keine Marker für eine durchgemachte HAV-Infektion.
