From 1997 to 2003, a population of 1800 individuals, potentially exposed to biological risk, was investigated to define the immunological status for Hepatitis B virus (HBV) and the degree of awareness of HBV vaccination. The results showed that 25 workers were positive to HBsAg, that is 1.3% (CI 1.01-1.40) of the total population examined; 6.4% (CI 4.2-8.6) showed positive markers of previous infection. Only 25% of the entire study population in the year 1997 and 44.4% in the year 2003 were vaccinated. The prevalence of vaccination was found among professional nurses and auxiliaries. No evidence of new infected cases was observed during the period of the study.

Abstract
From 1997 to 2003, a population of 1800 individuals, potentially exposed to biological risk, was investigated to define the immunological status for Hepatitis B virus (HBV) and the degree of awareness of HBV vaccination. The results showed that 25 workers were positive to HBsAg, that is 1.3% (CI 1.01-1.40) of the total population examined; 6.4% (CI 4.2-8.6) showed positive markers of previous infection. Only 25% of the entire study population in the year 1997 and 44.4% in the year 2003 were vaccinated. The prevalence of vaccination was found among professional nurses and auxiliaries. No evidence of new infected cases was observed during the period of the study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
