Infectious diseases related aeromedical evacuation of French soldiers in a level 4 military treatment facility: a ten year retrospective analysis.

BACKGROUND: Infectious diseases are a frequent cause of morbidity in French troops deployed abroad. They are usually minor in severity and managed by field practitioners. We aimed to describe the etiological spectrum of travel-related infections in French soldiers evacuated to a level 4 military treatment facility. METHODS: We evaluated the diagnoses of all service members who were medically evacuated from abroad to our infectious diseases department from January 1, 2004 to October 30, 2013. RESULTS: One hundred and twenty five cases, median age 32 years were referred, 117 (94%) were male and 78 (62%) were from the Army. Main areas of deployment were Africa in 80 cases (64%), Afghanistan in 15 cases (12%), and French Guiana in 10 cases (8%). Median time between initial consultation and hospitalization in the reference center was 5 days (IQ 2-7 d). Thirty (24%) immediate aeromedical evacuations were carried out. The top five diagnoses were Plasmodium falciparum malaria (30), fever of unknown origin (15), cerebro-meningeal infections (10), invasive amebiasis (9), and HIV primary infections (9). Thirteen individuals were admitted in ICU. No death was recorded. CONCLUSIONS: Infectious diseases were a rare of cause of medevac. Most of them were preventable. Lethal etiologies were represented by malaria and cerebro-meningeal infections.
