Comparison of trip characteristics of children and adults with travel-acquired hepatitis A infection.

We compared the trip characteristics of 84 child and 99 adult cases with travel-acquired hepatitis A (HA). Most pediatric cases had traveled in Asia for more than 30 days and had stayed and eaten most of their meals in the homes of friends and relatives in a country where they had not been born. In contrast, the adults with travel-acquired HA had visited Latin America or the Caribbean for 14 days or less and had stayed primarily in hotels. Specific public health interventions should be undertaken to prevent HA in traveling children.
