[Which are somatic diseases of migrant children ?].

WHICH ARE SOMATIC DISEASES OF MIGRANT CHILDREN? Migrant children form a vulnerable and heterogeneous population estimated at 70 000 in France. Their health is influenced by their living conditions in their home country, stress and exposure to pathogens, unsanitary housing and food insecurity during their migratory route and in their host country, as well as their parents psychological disorders. They present malnutrition, nutritional de¬ficiencies (iron and vitamin D), various dental, skin and intestinal infections, a significant prevalence of tuberculosis, and sometimes imported parasitic infections (malaria, schistosomiasis…) and lead poisoning.

[Autochthonous dengue].

Dengue is the arboviral disease that has massively spread in intertropical regions these past few years. The rise in imported cases of dengue and the rapid spread of the Aedes vector mosquitoes in continental France since 2004 explain the occurrence of indigenous dengue cases among the nonimmune population and points to an epidemic risk. Severe dengue cases are rare, but lethality is highest among children under 5 years of age.

[Fever in children returning from travel].

Child travelers are numerous, exposed to the risk of diseases, both infectious and noninfectious, for which practitioners often lack experience. The assessment of febrile returning child travelers is becoming more frequent and challenging. The question of previous travel should be foremost in the checklist of the interview of any febrile child traveler, because this implies a possible tropical disease such as malaria that may be life-threatening.
