In the aftermath of Hurricane Katrina's devastation in the Gulf Coast region, it is important for physicians in the United States to consider the infectious disease risks for children who have been displaced or who are still living in affected areas. These risks include infections acquired through ingestion of waterborne organisms; wound infections; lack of immunization continuity; and overcrowding, which increases the risk of respiratory or GI infections. In addition, problems will arise from disruption of therapy for select populations of children, such as those who are HIV-infected; those receiving immunosuppressive treatment; and those in need of continuous antibiotic prophylaxis, such as those who have sickle cell disease.

ABSTRACT: Children are at greater risk than adults for many travel-related problems, such as barotitis and barotrauma associated with flying, cold and heat injury, drowning, and infection with geohelminths. Most of these problems can be avoided with appropriate measures. To prevent insect-borne diseases, advise parents to apply permethrin to their children's clothing before the trip and apply slow-release DEET (30% to 35% concentration) to their skin every 24 hours. Infection with ground-dwelling parasites can be avoided by wearing protective footwear. At high altitudes, infants and children may experience acute mountain sickness. Acetozolamide (5 mg/kg/d, divided bid or tid) is an effective prophylactic; however, it is contraindicated in patients with sulfa allergy. Some preventive measures that are effective in adults may not be appropriate for children; for example, several medications used to control motion sickness are ineffective and associated with significant side effects in children.
