Resumen Objetivo. Determinar la tasa de prevalencia de la hepatitis A entre ciertos grupos de población de los condados

Objective. To determine the prevalence of Hepatitis A within subpopulations of southern California counties. Material and Methods. Age and race/ethnic-specific hepatitis A rates were derived from the California Department of Health Services Surveillance and Statistics Section for 1996-2001 and from demographic data of the California Department of Finance. Results. 2.3 million Latino children (aged 0-14 years) in five southern California counties had a rate of 31.1 cases per 100 000, five times higher than the non-Hispanic white rate. Conclusion. The CDC Advisory Committee on Immunization Practices recommends routine vaccination for children with “very high” rates of hepatitis A. The annual prevalence of hepatitis A in California, especially in southern California, met the CDC’s “very high” definition, therefore Latino children in these counties should be considered for routine childhood hepatitis A vaccination. As health has no borders, this issue should be addressed by the public health services of both, the United States’ and Mexico’s public health services.
