Dogs and sweets pose special risks when traveling with young children who love both. Along with the usual dietary precautions, Dr. Parker warned that frozen desserts may not be pasteurized. Parents should be told to seek care early if a child gets diarrhea. Much of the world has dog rabies, she added, so teaching children not to pet animals is important, albeit difficult. She recommended vaccinating children against rabies before travel to highly endemic areas. But she warned that a vaccinated child would have to be revaccinated if bitten.
“Vaccination is not enough. It just buys time,” Dr. Parker said, noting that postexposure prophylaxis is not available in some countries.
Visits to Families Abroad Pose Risks
Foreign-born families taking young children to meet relatives in their home countries face significantly greater health risks, compared with other travelers, according to Dr. Parker.
The youngsters are often very young; mothers may travel while pregnant; and, sometimes, family members are ill even before they leave on trips timed to family occasions, she said.
These families also stay longer, use less safe local transportation, and have difficulty refusing unsafe food or water in the homes of friends and relatives, Dr. Parker observed. As a result, visitors of friends and relatives are 10 times as likely to get malaria or typhoid as tourists.
Yet, foreign-born parents often do not seek medical advice before these journeys, according to Dr. Parker. Even if they have concerns, many don't seek pretravel advice because of the expense.
Some do not believe their families have to worry about organisms in the communities where they grew up. These travelers often see themselves and their children as “already immune,” which in large part is a myth, especially for their children, she said.
Even if they see a physician, travelers going back home are less likely to follow medical advice than are ecotourists, adventurers, missionaries, or relief workers traveling to developing countries.
