Larval vomiting during a mission in Haïti.

Following an original case report of massive regurgitation of maggots and the difficulty of medical management, we return to the fecal contamination problem for troops in the field. The survey of maggots has allowed for the diagnosis of contamination by ingestion of house fly eggs as a major infection vector. The successive ingestion of anti-acid and gastric dressing can induce an important diminution of gastric acidity that can allow for the proliferation of germs. In an operational context or natural catastrophe andin addition to field hygiene rules that are very important, it can also be useful to propose exclusive field rationsfor few daysin order to limit the interhuman contamination.
