Abstract excerpt

BACKGROUND: In spite of annual vaccination campaigns, hepatitis A cases increased in Catalonia (North-East Spain) in the period 2002-2005 calling for the elucidation of the underlying mechanisms associated to the epidemiological shifts. OBJECTIVE: The molecular characterization of the circulating strains to trace their origin and the study of the effects of vaccination on the incidence of sporadic and...
