The study revealed the occurrence of different patterns of hepatitis A endemicity in each city. The circulating strains characterized, whether in Cairo or Barcelona, were genotype IB. The effects of a child vaccination programme and the increase in the immigrant population on the overall hepatitis A occurrence in Barcelona were evaluated. While vaccination contributed to a significant decrease in the number of clinical cases, the huge recent immigration flow has probably been responsible for the re-emergence of the disease in the last year of study, in the form of small outbreaks among the non-vaccinated population.4 p.application/pdfeng(c) Cambridge University Press, 2007Hepatitis AVirus de l'hepatitis AHepatitis AHepatitis A virusinfo:eu-repo/semantics/article5481202023-02-21info:eu-repo/semantics/openAccess
