“…The data on AD incidences vary from country to country because of differences in case definition, surveillance systems, and/or the period of study. In France, a telephone survey estimated the incidence rate of acute gastroenteritis at 0.33 cases/person-year [14]. In the Netherlands, a population-based study conducted in 1998/1999 estimated that the gastroenteritis incidence was 283 per 1,000 person-years [15].…”

BackgroundData describing the epidemiology and management of viral acute diarrhea (AD) in adults are scant. The objective of this study was to identify the incidence, clinical characteristics, management and risk factors of winter viral AD in adults.MethodsThe incidence of AD in adults during two consecutive winters (from December 2010 to April 2011 and from December 2011 to April 2012) was estimated from the French Sentinelles network. During these two winters, a subset of Sentinelles general practitioners (GPs) identified and included adult patients who presented with AD and who filled out a questionnaire and returned a stool specimen for virological examination. All stool specimens were tested for astrovirus, group A rotavirus, human enteric adenovirus, and norovirus of genogroup I and genogroup II. Age- and sex-matched controls were included to permit a case–control analysis with the aim of identifying risk factors for viral AD.ResultsDuring the studied winters, the average incidence of AD in adults was estimated to be 3,158 per 100,000 French adults (95% CI [2,321 – 3,997]). The most reported clinical signs were abdominal pain (91.1%), watery diarrhea (88.5%), and nausea (83.3%). GPs prescribed a treatment in 95% of the patients with AD, and 80% of the working patients with AD could not go to work. Stool examinations were positive for at least one enteric virus in 65% (95% CI [57 – 73]) of patients with AD with a predominance of noroviruses (49%). Having been in contact with a person who has suffered from AD in the last 7 days, whether within or outside the household, and having a job (or being a student) were risk factors significantly associated with acquiring viral AD.ConclusionsDuring the winter, AD of viral origin is a frequent disease in adults, and noroviruses are most often the cause. No preventable risk factor was identified other than contact with a person with AD. Thus, at the present time, reinforcement of education related to hand hygiene remains the only way to reduce the burden of disease.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-014-0574-4) contains supplementary material, which is available to authorized users.

“…Healthcare-seeking behavior for acute gastroenteritis (AG) in France was assessed in a population-based survey carried out in 2009-2010 and identified duration of illness as the most important factor associated with consultation (Van Cauteren et al, 2012). Therefore, we estimated specific proportions of laboratory-confirmed campylobacteriosis or salmonellosis cases who had short (1-2 days), medium (3-5 days) and long (more than 5 days) duration of illness.…”

“…The number of cases that consulted is estimated at 327,026 (90%CrI 210,964-477,187) for campylobacteriosis and 100,190 (90%CrI 77,120-140,627) for salmonellosis. Yearly, an estimated 7 million persons consult for AG (Van Cauteren et al, 2012). Therefore, the prevalence of both infections among AG cases consulting a physician can be estimated at 1 per 21 and 1 per 70, respectively.…”

“…Since 2008, several surveys have been carried out in France in the general population, among physicians and laboratories to obtain specific information that was lacking to estimate the proportion of cases (un)recognized at each surveillance step (Bessède et al, 2011;Van Cauteren et al, 2012, 2015. The current study was performed to estimate the community incidence of campylobacteriosis and salmonellosis from the number of laboratory-confirmed cases reported to the NRC in mainland France (overseas French territories not included, hereafter referred to as France).…”

Community incidence estimates are necessary to assess the burden and impact of infections on health and to set priorities for surveillance, research, prevention, and control strategies. The current study was performed to estimate the community incidence of campylobacteriosis and nontyphoidal salmonellosis in France from the number of laboratory-confirmed cases reported to the national reference center (NRC). The probabilities of a case in the community visiting a doctor, having a stool sample requested, having a positive laboratory test, and having the case reported to the NRC were estimated using data of national surveillance systems, national hospitalization and health insurance databases, and specific surveys informing about these parameters. Credible intervals (CrI) were calculated using Monte Carlo simulation. In addition, we estimated the number of hospitalizations for both infections in France. The annual community incidence rate in France is estimated at 842 cases per 100,000 (90%CrI 525-1690) for campylobacteriosis and 307 cases per 100,000 (90%CrI 173-611) for salmonellosis. The annual number of hospitalizations is estimated at 5182 for campylobacteriosis and 4305 for salmonellosis. The multiplication factors between cases ascertained by the surveillance system and cases in the community were 115 for campylobacteriosis and 20 for salmonellosis. They are consistent with estimates reported in other countries, indicating a high community incidence of campylobacteriosis and salmonellosis in France.

“…We were only able to trace down 20 stool samples and four were sent to the NRL of enteric viruses, despite many calls and emails from ARS PACA. Studies in French general population [14] and in general practitioners [15] also indicate that few stool samples are requested. The study indicates that stool samples are requested five times more often in patients with bloody diarrhoea or with a long duration of illness before consultation.…”

Outbreak of diarrhoeal illness in participants in an obstacle adventure race, Alpes-Maritimes, France, June 2015

An acute gastroenteritis (AG) outbreak occurred among participants in an obstacle race in France in the summer of 2015. An investigation in two phases was conducted to identify the source of infection and document the extent of the outbreak. First, a message on a social media website asked racers to report any symptoms by email to the Regional Health Agency of Provence-Alpes-Côte d’Azur. Second, a retrospective cross-sectional study was conducted through an interactive questionnaire for all participants, followed by an analytical study of potential risks factors. Of 8,229 persons registered, 1,264 adults reported AG resolved within 48 hours. Of adults who reported AG, 866 met the case definition. Age group, departure time and ingestion of mud were associated with AG. Twenty stool specimens tested negative for bacteria. All four stool samples tested for viruses were positive for norovirus genogroup I and genotype 2. No indicator bacteria for faecal contamination were found in drinking water but muddy water of ponds tested positive. The outbreak was possibly caused by human-to-human transmission of a norovirus introduced by one or more persons and transmitted through contaminated mud. Risks related to similar races should be assessed and recommendations be proposed to raise awareness among health authorities and organisers.
