RESUMEN
We report a measles outbreak in a refugee settlement in Calais, France, between 5 January and 11 February 2016. In total, 13 confirmed measles cases were identified among migrants, healthcare workers in hospital and volunteers working on site. A large scale vaccination campaign was carried out in the settlement within two weeks of outbreak notification. In total, 60% of the estimated target population of 3,500 refugees was vaccinated during the week-long campaign.

BACKGROUND: There are very few permanent indicators of mental health in France; suicidal behavior is often only understood on the basis of deaths by suicide. METHOD: The epidemiological interest and methodological limits of four medico-administrative databases from which data on suicide attempts can be extracted have been the subject of a study in the Nord - Pas-de-Calais Region of France: telephone calls for emergency medical assistance after suicide attempt (2009 to 2011), admissions in emergency services with a diagnosis of suicide attempt (2012), medical-surgical hospital admissions as a result of suicide attempt (2009 to 2011), and psychiatric admissions with a diagnosis of suicide attempt (2011). RESULTS: Usable data were provided by one of two emergency medical assistance units, five of thirty emergency departments and all medical-surgical and psychiatric units; in data from the latter two sources, a unique anonymous identifier gave individual statistics, while the first two covered only suicide attempts. In 2011, the number of suicide attempt calls per 100,000 inhabitants was 304, whereas the number of hospitalisations with this diagnosis was 275; rates are highest in men between 20 and 49 years of age, and in women below 20 years of age and between 40 and 49. Sources are seen to be very homogeneous with regards to the average age at which suicide took place (between 37.8 and 38.5 years, depending on the source), and to the sex (55.0% to 57.6% of women). In 2011, the number of patients with a diagnosis of suicide attempt treated in psychiatry is 2.6 times lower than the number hospitalised for suicide attempt in medical-surgical units (3563 vs 9327). CONCLUSION: Permanent gathering of data, and the large volume of data recorded, should encourage the use of these databases in the definition and assessment of mental health policy: an increased contribution from emergency call centers and emergency services, and the coding of the suicidal nature of intoxications by a few clearly under-declaring units, must however be achieved in order to improve this source of information.

In May 2013, Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infection was diagnosed in an adult male in France with severe respiratory illness, who had travelled to the United Arab Emirates before symptom onset. Contact tracing identified a secondary case in a patient hospitalised in the same hospital room. No other cases of MERS-CoV infection were identified among the index case's 123 contacts, nor among 39 contacts of the secondary case, during the 10-day follow-up period.

INTRODUCTION: Scabies is a contagious parasitic infestation that is benign in most cases; however, delay in diagnosis and treatment can cause numerous problems for patients and people in their vicinity, as well as a risk of secondary spread. Following numerous reports suggesting increased incidence of scabies in France, we analysed various available indicators. METHODS: We analysed spontaneous and mandatory reports submitted to public health bodies as well as sales figures for scabies treatments in France over the period between 1999 and 2010. RESULTS: Reports submitted to public health structures suggest an increase in the number of cases of scabies both within the community and in healthcare establishments. An increase was seen in regional and national sales of scabies treatments. At the national level, between 2005 and 2009, sales rose from 283 to 402 bottles per 100,000 persons per year (+10% per year) for benzyl benzoate and from 216 to 495 treatments per 100,000 persons per year (+22%) for ivermectin. Based on these data, the minimum estimated annual incidence of scabies in France is 328 cases per 100,000 persons. DISCUSSION: There is some discussion surrounding the interpretation of these data, particularly the bias associated with reporting practice and with the protocols used to treat affected subjects and those in their vicinity. However, all of the information gathered indicates a real increase in the incidence of scabies in France, as a result of which we recommend increased information for the general public, clinical practitioners and public health partners in order to ensure early diagnosis and treatment.

Cholera is a bacterial infection, which causes digestive symptoms and massive diarrhoea. It may lead to dehydration and death if appropriate medical management is not rapidly initiated. Most cases of infection by choleric vibrio, however, remain symptom-free or may mimic common gastroenteritis. A review of two cases of imported cholera in France in the summer of 2005 and the community- and hospital-based investigation, which they triggered, enabled the incident management teams to assess risks of transmission. There were no secondary cases among 58 hospital contacts and 15 family contacts of the cases. Clinicians will find a discussion of possible clinical presentations and the risk of secondary transmission, in the context of progressing epidemics in countries, which have maintained close ties with France.

BACKGROUND: Hantaviral infections causing hemorrhagic fever with renal syndrome are endemic in North Eastern France. Humans are contaminated by the inhalation of aerosols contaminated by rodent faeces. In February 2003, the National reference centre (NRC) for hemorrhagic fevers detected an increased number of cases. An investigation was carried out to confirm the outbreak and take appropriate control measures. METHODS: Cases were collected by the NRC. A case was defined as a person living in France with symptoms compatible with hantaviral infection and a positive blood test both for specific Puumala IgM, and IgG. Clinical information and at-risk exposures during the 2 weeks before onset were recorded. RESULTS: In 2003, 128 cases were diagnosed (61 in 2002). The median age of patients was 38, 77% were men and 82% were hospitalized. Patients were living in North-Eastern France. Clusters were detected in the Ardennes and Oise districts. Occupation (35%) (in agriculture, forestry, and construction work), manipulation of firewood (35%), gardening (29%), and outdoors leisure (14%) were identified as at-risk exposures in these cases. CONCLUSIONS: An increased number of positive diagnoses of hantaviral infections was confirmed. The location and at-risk exposures of the cases were identical in previous investigations. Exclusion and prevention of rodents' access to houses and avoiding the inhalation of contaminated dust are the only possible prevention measures of hantaviral infections. Information about the disease and its prevention needs to be made widely available to both healthcare professionals and the general population living in endemic areas.

Salmonelloses are one are the main causes of foodborne infections in industrialised countries. In France, the incidence of human salmonellosis recorded by the National Reference Centre for Salmonella and Shigella (CNRSS) in 2001 was 21 cases per 100,000 inhabitants, and Salmonella serotype Enteritidis represented 39% of cases (1). This article reports the investigation results of two community outbreaks of salmonellosis that occurred simultaneously in the south west of France, and which were linked to the consumption of cheese made from raw milk.

RESUMEN
Serology is a helpful test for the diagnosis of human trichinellosis because clinical signs of this disease (fever and myalgias) are non specific. A lot of techniques have been studied but very few are commercialized and have been comparatively evaluated. We report here the performances of 4 commercially available kits: two Elisa tests, one western blot test & one latex agglutination test. The specificity and sensitivity of the different tests were assayed on 60 sera from patients with a proven trichinellosis and on 70 controls. The four tests had a 100% sensitivity. The specificity was of 98.6% for the western blot, of 93% for the latex agglutination test and of 87 & 77% for the two Elisa tests. Cross reactions are mainly observed in patients with other helminthic infections.

BACKGROUND: With the recent pertussis vaccine trials, the efficacy of acellular vaccines is now well known, estimated at 85% for multicomponent vaccines. On the other hand, the estimates of whole cell vaccines efficacy varies from 36% to 98% with the different vaccines used. We evaluated the field effectiveness of the French whole cell pertussis vaccine during outbreaks in schools and centers for disabled children. METHODS: Four limited outbreaks between 1993 and 1995 were investigated using a retrospective cohort study design. Vaccine effectiveness (VE) was assessed for the following case definition: clinical pertussis, laboratory-confirmed pertussis, epidemiologically confirmed pertussis (documented contact with a laboratory confirmed case). Immunization history was obtained by reviewing the child health record book. Effectiveness of a whole vaccination (four injections) and of a partial vaccination (one to three injections) were estimated as 1-(attack rate among vaccinated/attack rate among non-vaccinated). RESULTS: A whole immunization conferred good protection against pertussis with an estimated VE higher than 92% in three surveys, lower in the fourth survey (84%) in which antibiotic prophylaxis was set up very rapidly. A partial immunization conferred a mild protection (median: 60%). CONCLUSIONS: These results are consistent with a previous report about the effectiveness of this whole cell vaccine using the screening method in a hospital network survey in France. In the same way, a large efficacy trial in Senegal comparing it with an acellular bivalent vaccine estimated its efficacy at 96%. This high efficacy together with a satisfactory vaccine coverage leads to the current epidemiological profile of pertussis in childhood in France: majority of cases occurring before 6 months of age, limited outbreaks in school children, many of whom being unvaccinated or partially vaccinated.

Sorbitol-fermenting Escherichia coli O157:[H7] is a particularly virulent clone of E. coli O157:H7 associated with a higher incidence of haemolytic uraemic syndrome and a higher case fatality rate. Many fundamental aspects of its epidemiology remain to be elucidated, including its reservoir and transmission routes and vehicles. We describe an outbreak of sorbitol-fermenting E. coli O157:[H7] that occurred in France in 2011. Eighteen cases of paediatric haemolytic uraemic syndrome with symptom onset between 6 June and 15 July 2011 were identified among children aged 6 months to 10 years residing in northern France. A strain of sorbitol-fermenting E. coli O157:[H7] stx2a eae was isolated from ten cases. Epidemiological, microbiological and trace-back investigations identified multiply-contaminated frozen ground beef products bought in a supermarket chain as the outbreak vehicle. Strains with three distinct pulsotypes that were isolated from patients, ground beef preparations recovered from patients' freezers and from stored production samples taken at the production plant were indistinguishable upon molecular comparison. This investigation documents microbiologically confirmed foodborne transmission of sorbitol-fermenting of E. coli O157 via beef and could additionally provide evidence of a reservoir in cattle for this pathogen.

BACKGROUND: A cluster of indigenous typhoid fever cases in the greater Lille area, in January 2009, triggered investigations to identify the contamination source and to optimize care for infected individuals. METHODS: A case was defined as a person, living in the greater Lille area of, having presented with symptoms of typhoid fever, from January to March 2009. RESULTS: Sixteen cases of typhoid fever were identified between January 23 and March 22, 2009. Patients, none of whom had travelled, had all participated in a common meal on January 10, 2009. A woman, who helped prepare the meal and who had previously stayed in an endemic zone, was detected as the asymptomatic carrier of Salmonella Typhi. CONCLUSION: In France, although typhoid fever remains essentially an imported disease, there is a risk of indigenous epidemic and its diagnosis can be suggested for individuals who have not travelled. The features of this cluster illustrate the importance of respecting basic rules of hygiene in catering.

In 1997, a community-wide outbreak of Salmonella enterica serotype Typhimurium (S. typhimurium) infection occurred in France. The investigation included case searching and a case-control study. A case was defined as a resident of the Jura district with fever or diarrhoea between 12 May and 8 July 1997, from whom S. typhimurium was isolated in stool or blood. One hundred and thirteen cases were identified. Thirty-three (83 %) of 40 cases but only 23 (55 %) of 42 community controls, matched for age and area of residence, reported eating Morbier cheese (Odds ratio: 6.5; 95 % Confidence Interval: 1.4-28.8). Morbier cheese samples taken from the refrigerators of two case-patients and one symptom-free neighbour cultured positive for S. typhimurium of the same phage type as the human isolates. The analysis of distribution channels incriminated one batch from a single processing plant. These findings show that an unpasteurized soft cheese is an effective vehicle of S. typhimurium transmission.
