RESUMEN
This study estimates the association between emergency department (ED) visits for mental health disorders (MHDs) and the health context of the COVID-19 pandemic in the French region of Nouvelle-Aquitaine. This retrospective study took place between 2018 and 2021 using ED data. We defined the main exposure according to five periods: "Pre-pandemic (reference)", "First lockdown", "Second lockdown", "Third lockdown", and "Pandemic out-of-lockdown." We constructed the daily indicators for each MHD-related ED visit based on medical diagnoses. We described and then modeled the daily time series using generalized additive models with a quasi-Poisson regression. The analysis included 5,693,341 ED visits of which MHDs accounted for 4%. We observed a decline in ED use for most indicators, particularly during the first lockdown. Models revealed a statistically significant relative increase in ED visits for almost all MHDs during the first lockdown; for anxiety and child psychiatric disorders during the second lockdown; and only for child psychiatric disorders during the pandemic out-of-lockdown period. The public health crisis and lockdowns associated with the COVID-19 pandemic have been important sources of stress that could partially explain the deterioration of MHD indicators, thus leading to new public health concerns (notably among the youngest age group). Mental health is a major determinant of overall health and should therefore be considered in the management of crises that may require similar responses in the future.
RESUMEN
In September 2023, a severe outbreak of type B botulism with fifteen cases was linked to consumption of canned sardines at a restaurant in Bordeaux, France, during the Rugby World Cup. The cases were from seven countries. One death was recorded. Outbreak investigation using credit card data, rapid communication between health authorities of the affected countries and broad media communication allowed identification of cases and exposed persons and prevented further severe outcomes.

BACKGROUND: Consultation data from emergency general practitioners known as SOS Médecins and emergency departments (ED) from OSCOUR® network to the French syndromic surveillance system SurSaUD® (Surveillance sanitaire des urgences et décès). These data are aggregated and monitored on a daily basis through groupings of one or more medical symptoms or diagnoses ("syndromic groups" (SG)). The objective of this study was to evaluate, revise and enrich the composition of SGs through a consensus of experts who contributed or have experience in syndromic surveillance. METHODS: Three rounds of a Delphi survey were organised, involving 15 volunteers from SOS Médecins and 64 ED physicians in the OSCOUR® network as well as 8 international epidemiologists. Thirty-four SOS Médecins and 40 OSCOUR® SGs covering major medical specialities were put to the experts, along with their diagnostic codes and their surveillance objectives. In each round, the experts could retain or reject the codes according to the surveillance objective. The panel could also put forward new diagnostic codes in the 1st round, included in subsequent rounds. Consensus was reached for a code if 80% of participants had chosen to keep it, or less than 20% to reject it. RESULTS: A total of 12 SOS Médecins doctors (80%), 30 ED doctors (47%) and 4 international experts (50%) participated in the three rounds. All of the SGs presented to the panel included 102 initial diagnostic codes and 73 additional codes for SOS Médecins, 272 initial diagnostic codes and 204 additional codes for OSCOUR®. At the end of the 3 rounds, 14 SOS Médecins (40%) and 11 OSCOUR® (28%) SGs achieved a consensus to maintain all of their diagnostic codes. Among these, indicators of winter seasonal surveillance (bronchiolitis and gastroenteritis) were included. CONCLUSION: This study involved a panel of national experts with international representation and a good level of involvement throughout the survey. In the absence of a standard definition, the Delphi method has been shown to be useful in defining and validating syndromic surveillance indicators.

INTRODUCTION: Following the emergence of the COVID-19 epidemic in France, several preventive measures have been put in place, including a mandatory lockdown of the entire population. This measure was intended to slow down the viral circulation and protect the healthcare system, especially hospital departments. The aim of this study was to describe the activity of emergency department (ED) during the two lockdowns related to the COVID-19 epidemic in the Nouvelle-Aquitaine region. METHOD: A retrospective descriptive analysis of ED visits was performed for the period December 09, 2019 to December 20, 2020. The distribution of the number of ED visits was studied. RESULTS: ED visits decreased by 50% during the first lockdown in line with the COVID-19 epidemic and by 30% during the second. Hospitalization rate increased during the two lockdowns (+ 48% and + 20%, respectively). A differentiated use was observed during both lockdowns, with the emergence of the use of care for "coronavirus", "stroke" or "dyspnea / respiratory failure" while the typical pathologies "ENT infections" or "skin infections" were no more or less observed. CONCLUSION: Data from Oscour® allowed a real-time monitoring of the COVID-19 epidemic in France, and to assess the impact of lockdown on ED activity in the region. A decline in the use of healthcare services, the increase in hospitalization rate and the pathologies observed during the two lockdowns are in favour of a refocusing of the recourse for most serious pathologies.

A novel coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2) causing a cluster of respiratory infections (coronavirus disease 2019, COVID-19) in Wuhan, China, was identified on 7 January 2020. The epidemic quickly disseminated from Wuhan and as at 12 February 2020, 45,179 cases have been confirmed in 25 countries, including 1,116 deaths. Strengthened surveillance was implemented in France on 10 January 2020 in order to identify imported cases early and prevent secondary transmission. Three categories of risk exposure and follow-up procedure were defined for contacts. Three cases of COVID-19 were confirmed on 24 January, the first cases in Europe. Contact tracing was immediately initiated. Five contacts were evaluated as at low risk of exposure and 18 at moderate/high risk. As at 12 February 2020, two cases have been discharged and the third one remains symptomatic with a persistent cough, and no secondary transmission has been identified. Effective collaboration between all parties involved in the surveillance and response to emerging threats is required to detect imported cases early and to implement adequate control measures.

In 2013, 15 clusters of mumps were notified in France; 72% (82/114) of the cases had been vaccinated twice with measles-mumps-rubella vaccine. To determine whether the risk of mumps increased with time since the last vaccination, we conducted a case-control study among clusters in universities and military barracks. A confirmed case had an inflammation of a salivary gland plus laboratory confirmation in 2013. A probable case presented with inflammation of a salivary gland in 2013 either lasting for > 2 days or with epidemiological link to a confirmed case. Controls had no mumps symptoms and attended the same university course, student party or military barracks. We collected clinical and vaccination data via web questionnaire and medical records. We calculated adjusted odds ratios (aOR) using logistic regression. 59% (50/85) of cases and 62% (199/321) of controls had been vaccinated twice. The odds of mumps increased for twice-vaccinated individuals by 10% for every year that had passed since the second dose (aOR 1.10; 95% confidence interval (CI): 1.02-1.19; p = 0.02). Mumps immunity waned with increasing time since vaccination. Our findings contributed to the French High Council of Public Health's decision to recommend a third MMR dose during outbreaks for individuals whose second dose dates > 10 years.

BACKGROUND: Since the Covid-19 pandemic, bronchiolitis outbreaks have been subject to disrupted seasonality, and a major impact on the healthcare system was observed in 2022-23. OBJECTIVE: The aim of this article is to describe the characteristics of the 2022-23 bronchiolitis epidemic in the Nouvelle-Aquitaine region, and its impact on the healthcare system. METHOD: We described the indicators of dynamics, intensity, severity and impact provided by the bronchiolitis monitoring in place, and compared these with those from previous seasons. RESULTS: The intensity of the 2022-23 epidemic (emergency department visits: 23 %; SOS Médecins acts: 15 %), and its impact in terms of bronchiolitis-related hospitalizations (45 %) were higher than in previous seasons (p < 0.05). CONCLUSION: In addition to earliness, the 2022-23 bronchiolitis epidemic was significant as regards its exceptional scale and major impact on the hospital system, requiring adaptation of the preexisting healthcare offer in response to the anticipated demand.

Objective: Study the impact of 14th July 2016 Nice terrorist attack on Pediatric Emergency Department (PED) visits by youth under 18 years of age. Methods: PED visits diagnoses (ICD10) were clustered and analyzed based on retrospective data from the syndromic surveillance system of the Children's university hospital of Nice (Southern France). The studied period ranges from 2013 to 2019, i.e., 3 years before and after the terrorist attack of 14th July 2016. Results: Among 416,191 PED visits, the number of visits for stress in 4-17 years old appeared to increase in the 3 years after the attack compared to the 3 years before, particularly in September 2016 (acute effect) with 11 visits compared to an average of 2.3 visits per month from September 2013 to 2016 (p = 0.001827). In September 2017, we noticed 21 visits compared to an average of 4.8 visits per month during the following period (2013-2019). In 2017, PED visits for stress among 4-17 year olds were higher in comparison to the other years of the study: 107 visits compared to an annual average of 57. Conclusion: To our knowledge, this is the first study of the use of the pediatric care system before and after a terrorist attack involving syndromic surveillance. This suggests acute and long-term effects of the terrorist attack on PED use by youth for mental health issues. Further studies of the pediatric care system involving syndromic surveillance are needed in the context of mass violent events, such as terrorist attacks.

INTRODUCTION: In the French mainland administrative region Nouvelle-Aquitaine, syndromic surveillance is based on hospital emergency data, mortality data, and data from associations belonging to the SOS Médecins network. The aim of the present article is to describe the functioning of this network and to illustrate its use for syndromic surveillance in Nouvelle-Aquitaine. METHOD: The SOS Médecins network participates in the syndromic surveillance system SurSaUD, developed by Santé publique France (SpF; the French National Public Health Agency; Saint-Maurice, Paris, France). Near real-time data are automatically transmitted daily to a data server and analyzed by SpF's Nouvelle Aquitaine's regional unit to identify, monitor, and evaluate the impact of expected and unexpected health events in the region. RESULTS: The SOS Médecins network has five local associations spread across the region with 146 participating physicians. Data have been recorded for more than 10 years and represented nearly 481,000 visits in 2017. The resulting database has helped to identify and monitor seasonal epidemics and unexpected events, as well as measure the health impact of these events. CONCLUSION: The data from the SOS Médecins network are an essential source in syndromic surveillance. They complement surveillance data from other sources. More specifically, mortality and emergency unit traffic reflect the most severe cases, while SOS Médecins data help early detection of epidemics and health events in the general population. The network has shown its responsiveness and its reliability, not only for the surveillance of seasonal epidemics, but also for the detection of unusual signals. It therefore constitutes an essential link in syndromic surveillance in France, and specifically in the Nouvelle-Aquitaine region.
