RESUMEN

On 13 April 2011 the medical service of a French military parachuting unit reported an outbreak of acute gastroenteritis involving 147 persons among the military personnel. Meals suspected to have caused the outbreak (pasta and some raw vegetables) were tested for norovirus by PCR. The same norovirus (genogroup I) was found in some of the food items consumed by the cases and in a cook who prepared the meals.

RESUMEN

OBJECTIVE: Since the start of 2010 there has been a flare-up of measles in France, following on the resurgence observed in 2008. The aim of this study was to present results of the epidemiological surveillance of measles in the French armed forces in metropolitan France and to describe the outbreak that occurred in 2010 and 2011. METHODS: Criteria for report were those used for French national compulsory notification. The data, concerning active military personnel, were derived from epidemiological surveillance from 1992 to 2011 for the incidence rates and from notification forms completed in 2010 and 2011 by the military practitioners for the description of characteristics of cases. RESULTS: Between January 1992 and July 2010, 833 cases of measles were reported. Since 2002, the mean incidence rate had been 1 case p.100,000. A significant increase in incidence was observed in 2010 (10.1 p.100,000) and in 2011 (41.4 p.100,000). Clusters of cases accounted for 72.3% of cases. Rates were much higher among subjects under 30. Only 68.6% of cases had been previously vaccinated with at least one dose of MMR vaccine. The mean vaccine coverage among contacts of cases was approximated to 54.3%. CONCLUSIONS: The outbreak of measles observed in 2010 and 2011 in the French armed forces followed the same pattern as that observed nationally and at European level, and can be seen as the likely consequence of inadequate vaccination coverage.

RESUMEN

OBJECTIVE: Aim of this study was to describe the main characteristics of food-borne disease outbreaks (FBDOs) in the French armed forces from 1999 to 2009. METHODS: FBDOs are reported to the military epidemiological surveillance system, which concerns all active military personnel. Investigation reports published from 1999 to 2009 were reviewed. RESULTS: Among the 180 FBDOs reported, 48.3% occurred overseas. The mean reporting rate was 2.4 outbreaks p.100,000 in France and 26.7 p.100,000 overseas, reaching to 39.3 p.100,000 in Africa. Digestive symptoms were predominant among cases. Laboratory analyses on cases were positive in 29.4% of FBDOs. The most frequently isolated agents were shigella (15.4%). Laboratory analyses on food samples were positive in 18.9% of outbreaks, the most frequently isolated agent being Clostridium perfringens (15.7%). Only 7 FBDOs were documented by concordant analyses in both patients and food samples. CONCLUSIONS: The reporting rate was much higher among military deployed overseas, which can be the consequence of a lack of hygiene due to operational imperatives and the consumption of local food which does not meet safety standards. In operational settings, laboratory evidence may be difficult to obtain and a timely epidemiological investigation in some cases proves valuable to identify the likely vehicle of infection and to guide targeted intervention measures.
