title: Hepatitis A Virus Infection, Vaccination and Iranian Healthcare Workers.
abstract: BACKGROUND
  Hepatitis A virus (HAV) infection is an important public health problem. It is estimated that about 1.4 million cases of HAV infection occur every year worldwide. Non-immune healthcare workers (HCWs) can be at higher risk of HAV infection in comparison to general population and an appropriate preventive method should be considered for them.
  
  
  METHODS
  For finding related articles, a comprehensive search was performed in Scopus, PubMed and Google Scholar and all appropriate combinations of following keywords were considered; "healthcare provider", "healthcare personnel", "healthcare worker", "nurse" "medical students", "Iran", "Hepatitis A" and "vaccination". Also we did a search in Persian language in Google scholar and scientific information database (SID) to find related Persian literature.
  
  
  RESULTS
  A gradual shift in age of HAV infection has been seen from childhood toward adulthood. Data about HAV seropositivity among Iranian HCWs are very limited. However based on the recent studies, it seems that HAV seropositivity has been reduced among HCWs in comparison with the past. All recent studies have suggested HAV vaccination for HCWs.
  
  
  CONCLUSIONS
  Available limited studies show that Iranian healthcare personnel need HAV vaccination. However, for selecting an appropriate preventive method for this high risk group, more original studies are still needed.
