Hepatitis A among schoolchildren in a US-Mexico border community

Am J Public Health. 1997 Oct;87(10):1715-7. doi: 10.2105/ajph.87.10.1715.


Objectives: A cross-sectional study investigated the association of hepatitis A seropositivity with environmental and personal risk factors among children in a United States-Mexico border community.

Methods: Hepatitis A serological markers and a questionnaire identifying risk factors were evaluated for 523 primary school children.

Results: Of the children studied, 16.9% tested positive for total antihepatitis A virus. Risk factors included being in the first grade, low maternal educational attainment, living in Mexico for more than 6 months, household crowding, and inadequate excreta disposal systems.

Conclusions: To decrease enteric disease, improvements in excreta disposal infrastructures and educational programs are needed. Hepatitis A vaccine should be administered before school age.
