Results: Among the 383 HCWs interviewed nurses were 72% (277) and Lab workers were 27.5 %( 106) .There age ranged from17-59 years with mean age of 34.38 years. 41% of health care workers had service length between 1-5 years. 57.6 %( 221) were completely vaccinated, 18.3 %( 70) partially vaccinated and 24 %( 92) were not vaccinated at all. Awareness and attitude problem was identified as the main factor responsible for lack of vaccination. 53.5% (206) had been exposed to needle stick injury at least 1-5 times in their whole professional life. 48.1% (99) of the needle stick injury exposed personnel were aware of post exposure prophylaxis whereas 51.9 %( 107) of them were ignorant of standard prophylaxis.
Most of the individuals knew their Hepatitis B and C status i.e. 93.7% (359) while 6.3 %( 24) had never got themselves tested for hepatitis B& C. Hepatitis B positive were 0.5 %( 2), while 1.6 %( 6) were Hepatitis C positive among 359 HCWs.
Conclusion: Percentage of HCWs vaccinated was low and the main factor responsible was awareness and
attitude problem. At the same time non- availability of vaccine by the employer had been identified as the second
most important reason for non vaccination.
Half of the studied group was not aware of the precise post exposure prophylaxis .The prevalence of Hepatitis B
and C was low in this high risk group as compared to general population of the area.
