The epidemiology of viral hepatitis in children in South Texas : Increased prevalence of hepatitis A along the Texas-Mexico border.
An initial retrospective study of 194 children demonstrated a high prevalence of hepatitis A but not hepatitis B or C infection among children living along the Texas-Mexico border.
A larger prospective study of hepatitis A was conducted with 285 children (aged 6 months to 13 years) living in 3 sociodemographically dissimilar areas of South Texas.
Children living in colonias along the border had a significantly higher prevalence of hepatitis A virus infection (37%) than children living in urban border communities (17%) or in a large metropolitan area (San Antonio [6% ]). Independent risk factors for hepatitis A infection included increased age, colonia residence, and history of residence in a developing country.
Use of bottled water (vs. municipal or spring/well water) and years of maternal secondary education were protective.
Improved sanitation or routine hepatitis A vaccination in early childhood may reduce the prevalence of hepatitis A in these areas.
