title: [Prevalence of HCV infection in infants - own clinical experience].
abstract: Hepatitis type C (HCV) infection is one of the most serious health problems in the child population. Due to the clinical course of infection the diagnosis is often incidentally diagnosed in infants. Prevalence of HCV infection in the infant population is not well reported.
  
  
  OBJECTIVE
  of the study was to estimate the prevalence of HCV infection in infants.
  
  
  METHODS
  retrospective analysis of medical records of 278 infants (138 girls and 140 boys) aged from 3 weeks to 12 months (medium age 7.6 months) hospitalized in our department between 2002 and 2005, was performed. Serum anti-HCV antibodies using the third generation ELISA test (ARCHITEKT Anti-HCV) were examined in all of the children. The majority of children (54%) have been hospitalized at least one time. 85 infants (30.6%) have been hospitalized once and 128 infants (46%) haven not been previously hospitalized.
  
  
  RESULTS
  among 278 children we found HCV antibodies only in one 6-months old infant, who was previously hospitalized twice. After 6 weeks a control study was done and no anti-HCV antibodies were detected.
  
  
  CONCLUSIONS
  1. In spite of a continuously increasing number of HCV infections in general population in Poland during the last few years, infection among infants is rather rare. 2. Epidemiological studies of prevalence of HCV infection in infants should be carried out.
