Results from the SARS-CoV-2 wastewater-based surveillance system in Denmark, July 2021 to June 2022.

The microbiological analysis of wastewater samples is increasingly used for the surveillance of SARS-CoV-2 globally. We described the setup process of the national SARS-CoV-2 wastewater-based surveillance system in Denmark, presented its main results during the first year of activities, from July 2021 to June 2022, and discussed their operational significance. The Danish SARS-CoV-2 wastewater-based surveillance system was designed to cover 85 % of the population in Denmark and it entailed taking three weekly samples from 230 sites. Samples were RT-qPCR tested for SARS-CoV-2 RNA, targeting the genetic markers N1, N2 and RdRp, and for two faecal indicators, Pepper Mild Mottle Virus and crAssphage. We calculated the weekly SARS-CoV-2 RNA concentration in the wastewater from each sampling site and monitored it in view of the results from individual testing, at the national and regional levels. We attempted to use wastewater results to identify potential local outbreaks, and we sequenced positive wastewater samples using Nanopore sequencing to monitor the circulation of viral variants in Denmark. The system reached its full implementation by October 2021 and covered up to 86.4 % of the Danish population. The system allowed for monitoring of the national and regional trends of SARS-CoV-2 infections in Denmark. However, the system contribution to the identification of potential local outbreaks was limited by the extensive information available from clinical testing. The sequencing of wastewater samples identified relevant variants of concern, in line with results from sequencing of human samples. Amidst the COVID-19 pandemic, Denmark implemented a nationwide SARS-CoV-2 wastewater-based surveillance system that integrated routine surveillance from individual testing. Today, while testing for COVID-19 at the community level has been discontinued, the system is on the frontline to monitor the occurrence and spread of SARS-CoV-2 in Denmark.

The effect of changing diagnostic method from culture to PCR on the number of episodes of human campylobacteriosis in Denmark: a retrospective study (2015-2022).

IMPORTANCE: This study is important because it shows the potential epidemiological silence associated with the use of culture as the primary diagnostic method for the laboratory identification of human campylobacteriosis. Also, we show how polymerase chain reaction methods are associated with a systematic increase in the number of human campylobacteriosis episodes as reported by routine disease surveillance. These findings are operationally relevant and have public health implications because they tell how crucial it is to consider changes in diagnostic methods, e.g., in the epidemiological analysis of historical data and in the interpretation of future data in light of the past. We also believe that this study highlights how the synergy between microbiology and epidemiology is essential for disease surveillance.

Mapping food surveillance chains through different sectors.

European countries are investing in strengthening disease surveillance from a One Health (OH) perspective. During the MATRIX project, in the context of the One Health European Joint Programme, existing surveillance chains across the sectors of animal health, food safety, and public health have been investigated through questionnaires. Provided information has then been selected to be displayed in a single slide using an implemented mapping template. Two real-life scenarios are presented as case studies: the surveillance activities in place in France for Salmonella in the pork meat food chain, and in Norway for Listeria monocytogenes in the dairy food chain. The results collected through the questionnaires and the lessons learnt during the mapping process are reported, to share the advantages and drawbacks of the methodology. Moreover, the presented template could be adjusted and applied to different contexts. Mapping the components of existing disease surveillance systems is a fundamental step in understanding the relationships between its components, and subsequently facilitating their collaboration and integration under a OH approach.

Trends in human leptospirosis in Denmark, 2012-2021.

Leptospirosis is a zoonotic bacterial infection that can cause influenza-like symptoms and severe disease. In Denmark, leptospirosis is rare, non-endemic, and most commonly transferred to humans from mice and rats. Cases of human leptospirosis in Denmark are by law notifiable to Statens Serum Institut. This study aimed to describe trends in incidence of leptospirosis in Denmark from 2012 to 2021. Descriptive analyses were used to calculate the incidence, geographical distribution and possible routes of infection, as well as testing capacity and serological trends. The overall incidence rate was 0.23 per 100,000 inhabitants, with the highest annual incidence of 24 cases in 2017. Men between 40-49 years old were the demographic group most commonly diagnosed with leptospirosis. August and September were the months with highest incidence over the entire study period. The most common serovar observed was Icterohaemorrhagiae, although over a third of cases were diagnosed via polymerase chain reaction alone. The most common sources of exposure reported were travel abroad, farming, and recreational contact with fresh water, the latter being a new exposure compared to previous studies. Overall, a One Health approach would ensure better detection of outbreaks and milder disease. Additionally, preventative measures should be expanded to include recreational water sports.

Search term "One Health" remains of limited use to identify relevant scientific publications: Denmark as a case study.

One Health has become a popular approach, and scientific advancements in the field should be easily findable and accessible to a wide range of relevant audiences, from researchers to policymakers, and across sectors. We conducted a systematic narrative review of available scientific publications concerning One Health in the setting of Denmark that were retrievable using "One Health" as the key search term. Three searches in two databases yielded 30 retrieved publications, 13 of which were included in the review. The included publications had been published between 2015 and 2021. Twelve of the included publications were co-authored in collaboration across institutes from different sectors. Three of the included publications had focus on antimicrobial resistance, three on disease surveillance and/or control, and five were assessments or evaluations. The overall number of publications identified by a search using "One Health" as the key search term was small, and the search identified some publications that were not relevant to One Health. Our work thus highlights a missed scientific and communication opportunity of signposting articles as relevant to One Health. Using the expression "One Health" as keyword could help making One Health research more easily findable and thereby obtaining an overview of research in the field.

Spotlight influenza: Influenza surveillance before and after the introduction of point-of-care testing in Denmark, season 2014/15 to 2018/19.

BackgroundIn Denmark, influenza surveillance is ensured by data capturing from existing population-based registers. Since 2017, point-of-care (POC) testing has been implemented outside the regional clinical microbiology departments (CMD).AimWe aimed to assess influenza laboratory results in view of the introduction of POC testing.MethodsWe retrospectively observed routine surveillance data on national influenza tests before and after the introduction of POC testing as available in the Danish Microbiological Database. Also, we conducted a questionnaire study among Danish CMD about influenza diagnostics.ResultsBetween the seasons 2014/15 and 2018/19, 199,744 influenza tests were performed in Denmark of which 44,161 were positive (22%). After the introduction of POC testing, the overall percentage of positive influenza tests per season did not decrease. The seasonal influenza test incidence was higher in all observed age groups. The number of operating testing platforms placed outside a CMD and with an instrument analytical time ≤ 3 h increased after 2017. Regionally, the number of tests registered as POC in the Danish Microbiological Database and the number of tests performed with an instrument analytical time ≤ 3 h or outside a CMD partially differed. Where comparable (71% of tests), the relative proportion of POC tests out of all tests increased from season 2017/18 to 2018/19. In both seasons, the percentage of positive POC tests resulted slightly lower than for non-POC tests.ConclusionPOC testing integrated seamlessly into national influenza surveillance. We propose the use of POC results in the routine surveillance of seasonal influenza.

Preliminary report of an outbreak of SARS-CoV-2 in mink and mink farmers associated with community spread, Denmark, June to November 2020.

In June-November 2020, SARS-CoV-2-infected mink were detected in 290 of 1,147 Danish mink farms. In North Denmark Region, 30% (324/1,092) of people found connected to mink farms tested SARS-CoV-2-PCR-positive and approximately 27% (95% confidence interval (CI): 25-30) of SARS-CoV-2-strains from humans in the community were mink-associated. Measures proved insufficient to mitigate spread. On 4 November, the government ordered culling of all Danish mink. Farmed mink constitute a potential virus reservoir challenging pandemic control.

Distribution of household disinfection kits during the 2014-2015 Ebola virus outbreak in Monrovia, Liberia: The MSF experience.

During the initial phase of the 2014-2016 Ebola virus disease (EVD) outbreak in Monrovia, Liberia, all hospitals' isolation capacities were overwhelmed by the sheer caseload. As a stop-gap measure to halt transmission, Medecins sans Frontieres (MSF) distributed household disinfection kits to those who were at high risk of EVD contamination. The kit contained chlorine and personal protective materials to be used for the care of a sick person or the handling of a dead body. This intervention was novel and controversial for MSF. This paper shed the light on this experience of distribution in Monrovia and assess if kits were properly used by recipients. Targeted distribution was conducted to those at high risk of EVD (relatives of confirmed EVD cases) and health staff. Mass distributions were also conducted to households in the most EVD affected urban districts. A health promotion strategy focused on the purpose and use of the kit was integrated into the distribution. Follow-up phone calls to recipients were conducted to enquire about the use of the kit. Overall, 65,609 kits were distributed between September and November 2014. A total of 1,386 recipients were reached by phone. A total of 60 cases of sickness and/or death occurred in households who received a kit. The majority of these (46, 10%) were in households of relatives of confirmed EVD cases. Overall, usage of the kits was documented in 56 out of 60 affected households. Out of the 1322 households that did not experience sickness and/or death after the distribution, 583 (44%) made use of elements of the kit, mainly (94%) chlorine for hand-washing. At the peak of an EVD outbreak, the distribution of household disinfection kits was feasible and kits were appropriately used by the majority of recipients. In similar circumstances in the future, the intervention should be considered.

Assault and care characteristics of victims of sexual violence in eleven Médecins Sans Frontières programs in Africa. What about men and boys?

BACKGROUND: Often neglected, male-directed sexual violence (SV) has recently gained recognition as a significant issue. However, documentation of male SV patients, assaults and characteristics of presentation for care remains poor. Médecins Sans Frontières (MSF) systematically documented these in all victims admitted to eleven SV clinics in seven African countries between 2011 and 2017, providing a unique opportunity to describe SV patterns in male cases compared to females, according to age categories and contexts, thereby improving their access to SV care. METHODS AND FINDINGS: This was a multi-centric, cross-sectional study using routine program data. The study included 13550 SV cases, including 1009 males (7.5%). Proportions of males varied between programs and contexts, with the highest being recorded in migratory contexts (12.7%). Children (<13yrs) represented 34.3% of males. Different SV patterns appeared between younger and older males; while male children and adolescents were more often assaulted by known civilians, without physical violence, adult males more often endured violent assault, perpetrated by authority figures. Male patients presented more frequently to clinics providing integrated care (medical and psychological) for victims of violence (odds ratio 3.3, 95%CI 2.4-4.6), as compared to other types of clinics where SV disclosure upon admission was necessary. Males, particularly adults, were disproportionately more likely to suffer being compelled to rape (odds ratio 12.9, 95%CI 7.6-21.8).Retention in SV care was similar for males and females. CONCLUSIONS: Patterns of male-directed SV varied considerably according to contexts and age categories. A key finding was the importance of the clinic setup; integrated medical and SV clinics, where initial disclosure was not necessary to access care, appeared more likely to meet males' needs, while accommodating females' ones. All victims' needs should be considered when planning SV services, with an emphasis on appropriately trained and trauma-informed medical staff, health promotion activities and increased psychosocial support.

2017 Outbreak of Ebola Virus Disease in Northern Democratic Republic of Congo.

BACKGROUND: In 2017, the Democratic Republic of the Congo (DRC) recorded its eighth Ebola virus disease (EVD) outbreak, approximately 3 years after the previous outbreak. METHODS: Suspect cases of EVD were identified on the basis of clinical and epidemiological information. Reverse transcription-polymerase chain reaction (RT-PCR) analysis or serological testing was used to confirm Ebola virus infection in suspected cases. The causative virus was later sequenced from a RT-PCR-positive individual and assessed using phylogenetic analysis. RESULTS: Three probable and 5 laboratory-confirmed cases of EVD were recorded between 27 March and 1 July 2017 in the DRC. Fifty percent of cases died from the infection. EVD cases were detected in 4 separate areas, resulting in > 270 contacts monitored. The complete genome of the causative agent, a variant from the Zaireebolavirus species, denoted Ebola virus Muyembe, was obtained using next-generation sequencing. This variant is genetically closest, with 98.73% homology, to the Ebola virus Mayinga variant isolated from the first DRC outbreaks in 1976-1977. CONCLUSION: A single spillover event into the human population is responsible for this DRC outbreak. Human-to-human transmission resulted in limited dissemination of the causative agent, a novel Ebola virus variant closely related to the initial Mayinga variant isolated in 1976-1977 in the DRC.

Introduction of a standardised protocol, including systematic use of tranexamic acid, for management of severe adult trauma patients in a low-resource setting: the MSF experience from Port-au-Prince, Haiti.

BACKGROUND: Bleeding is an important cause of death in trauma victims. In 2010, the CRASH-2 study, a multicentre randomized control trial on the effect of tranexamic acid (TXA) administration to trauma patients with suspected significant bleeding, reported a decreased mortality in randomized patients compared to placebo. Currently, no evidence on the use of TXA in humanitarian, low-resource settings is available. We aimed to measure the hospital outcomes of adult patients with severe traumatic bleeding in the Médecins Sans Frontières Tabarre Trauma Centre in Port-au-Prince, Haiti, before and after the implementation of a Massive Haemorrhage protocol including systematic early administration of TXA. METHODS: Patients admitted over comparable periods of four months (December2015- March2016 and December2016 - March2017) before and after the implementation of the Massive Haemorrhage protocol were investigated. Included patients had blunt or penetrating trauma, a South Africa Triage Score ≥ 7, were aged 18-65 years and were admitted within 3 h from the traumatic event. Measured outcomes were hospital mortality and early mortality rates, in-hospital time to discharge and time to discharge from intensive care unit. RESULTS: One-hundred and sixteen patients met inclusion criteria. Patients treated after the introduction of the Massive Haemorrhage protocol had about 70% less chance of death during hospitalization compared to the group "before" (adjusted odds ratio 0.3, 95%confidence interval 0.1-0.8). They also had a significantly shorter hospital length of stay (p = 0.02). CONCLUSIONS: Implementing a Massive Haemorrhage protocol including early administration of TXA was associated with the reduced mortality and hospital stay of severe adult blunt and penetrating trauma patients in a context with poor resources and limited availability of blood products.

Surgery with Limited Resources in Natural Disasters: What Is the Minimum Standard of Care?

PURPOSE OF REVIEW: In a challenging scenario, such as in the aftermath of a natural disaster, minimum standards of care must be in place from the moment surgical care activities are launched. RECENT FINDINGS: Natural disasters cause destruction and human suffering, especially in low- and middle-income countries, which suffer the most when exposed to their consequences. Health systems can quickly get overwhelmed and can collapse under the burden of injured patients during this event, while qualified surgical care remains crucial. Medécins Sans Frontières (MSF) has a vast experience providing surgical care after natural disasters, and quality is assured through the Donabedian model. Minimum structure standards are put in place from the beginning of an emergency response, together with standard operating procedures providing guidance to professionals working in challenging conditions. SUMMARY: MSF believes that it is always possible to deliver surgical care, ensuring the best possible quality guaranteeing adequate levels of structure and process. The "do no harm" principle must always be respected as adherence to medical ethics is a must in any context, even a challenging one.

Delamanid for rifampicin-resistant tuberculosis: a retrospective study from South Africa.

Experience with delamanid (Dlm) is limited, particularly among HIV-positive individuals. We describe early efficacy and safety data from a programmatic setting in South Africa.This was a retrospective cohort study of patients receiving Dlm-containing treatment regimens between November 2015 and August 2017. We report 12-month interim outcomes, sputum culture conversion (SCC) by months 2 and 6, serious adverse events (SAEs) and QT intervals corrected using the Frederica formula (QTcF).Overall, 103 patients were initiated on Dlm; 79 (77%) were HIV positive. The main indication for Dlm was intolerance to second-line anti-tuberculosis (TB) drugs (n=58, 56%). There were 12 months of follow-up for 46 patients; 28 (61%) had a favourable outcome (cure, treatment completion or culture negativity). Positive cultures were found for 57 patients at Dlm initiation; 16 out of 31 (52%) had SCC within 2 months and 25 out of 31 (81%) within 6 months. There were 67 SAEs reported in 29 patients (28%). There were four instances of QTcF prolongation >500 ms in two patients (2%), leading to permanent discontinuation in one case; however, no cardiac arrhythmias occurred.This large cohort of difficult-to-treat patients receiving Dlm for rifampicin-resistant TB treatment in a programmatic setting with high HIV prevalence had favourable early treatment response and tolerated treatment well. Dlm should remain available, particularly for those who cannot be treated with conventional regimens or with limited treatment options.

Blended SORT-IT for operational research capacity building: the model, its successes and challenges.

The Structured Operational Research Training Initiative (SORT-IT) has been shown to be very effective in strengthening capacity for conducting operational research, publishing in scientific journals and fostering policy and practice change. The 'classic' model includes three face-to-face modules during which, respectively, a study protocol, a data analysis plan, and a manuscript are elaborated. Meanwhile, the lectures of the SORT-IT are available online as YouTube videos. Given the availability of this online material and the experiences with online mentorship of the faculty, we piloted a first blended distance/residential SORT-IT. To inform future implementers of our experience with blended operational research courses, we summarize the model, successes, and challenges of this approach in this perspective paper. The blended SORT-IT consisted of an online phase, covering modules 1 and 2, followed by a face-to-face writing module 3. Four out of six participants successfully completed the course, and submitted a manuscript to a peer-reviewed journal within four weeks of completing module 3. A blended approach may make the SORT-IT course more accessible to future participants and may favour the adoption of the course by other institutions, such as national Ministries of Health.

The Ebola-effect in Guinea 2014-15: Tangled trends of malaria care in children under-five.

INTRODUCTION: The 2014-15 Ebola outbreak in West Africa was disruptive for the general health services in the affected countries. This study assessed the impact of the outbreak on the reported number and management of malaria in children under-five in rural Guinea. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted in nineteen health centres in two rural, malaria-endemic health districts, one at the epicentre of the outbreak (Guéckédou) and one (Koubia) spared by Ebola. Routine surveillance data at health facility level were compared over similar periods of high malaria transmission in both districts before, during and after the outbreak. RESULTS: There were significant declines in the number of visits during the Ebola outbreak (3,700) in Guéckédou compared to before (4,616) and after it (4,195), while this trend remained more stable within the three periods for Koubia. Differences were nonetheless significant in both districts (p<0.001). In 2014, during the peak of the outbreak, the overall number of malaria cases treated exceeded the number of confirmed malaria cases in Guéckédou. There were decreases in antimalarial treatment provision in August and November 2014. In contrast, during 2015 and 2016, the proportion of malaria positive cases and those treated were closely aligned. During the peak of the Ebola outbreak, there was a significant decrease in oral antimalarial drug administration, which corresponded to an increase in injectable antimalarial treatments. Stock-outs in rapid diagnostic tests were evident and prolonged in Guéckédou during the outbreak, while more limited in Koubia. CONCLUSION: The Ebola outbreak of 2014-15 in Guinea had a significant impact on the admission and management of malaria in children under-five. This study identifies potential challenges in the delivery of care for those at highest risk for malaria mortality during an Ebola outbreak and the need to improve preparedness strategies pre-Ebola and health systems recovery post-Ebola.

Political priority of oral health in Italy: an analysis of reasons for national neglect.

PURPOSE: Oral health remains a neglected area and its political priority on most national agendas is low. This analysis aimed to identify the political priority of oral health in Italy. BACKGROUND: Italian public health services are decentralised at the regional level and are financed by both central and local authorities. Despite certain legally guaranteed public oral health services, access to oral health care seems to be inhomogeneous. METHODS: Appraisal of the political priority of oral health in Italy uses the Political Power Framework as proposed by Shiffman and Smith. RESULTS AND DISCUSSION: There is no clear mandate for leadership or coordination within the oral health sector, resulting in fragmentation and in dominance of the private sector. As a consequence, oral diseases are mainly addressed through a curative rather than a preventive public health approach. Current, systematic and representative data are lacking. Therefore, the real burden of oral diseases is unknown and thus cannot be addressed adequately. Evidence-based, cost-effective and sustainable population-wide public dental health interventions are not implemented on a large scale, and growing inequities in terms of access to care are not seen as a concern. CONCLUSION: Lack of relevant policies with a public health focus, absence of systematic oral health surveillance and limited access to care for large population groups are strong indicators that oral health is not a political priority. However, opportunities in the wider political environment could be used to facilitate analysis, discussion and change in order to improve political priority of oral health in Italy.

Tobacco and dental caries: a systematic review.

OBJECTIVE: Despite the abundance of evidence linking tobacco consumption to many oral conditions, no systematic review of the relationship with dental caries is available. The main aim of this systematic review was, therefore, to evaluate the effect of tobacco smoking on dental caries in adult smokers. MATERIALS AND METHODS: According to the PRISMA checklist, observational studies published from January 1991 to June 2011 were reviewed. The quality of evidence for each finding was rated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS: Five studies, four related to dental caries and one on oral bacteria activity, were finally included in a qualitative analysis; they were all cross-sectional studies. As a result, the overall quality of evidence was poor, with two articles given a score of very low and three a score of low according to GRADE. CONCLUSIONS: Tobacco smoking was found to be associated with an increased risk of dental caries. However, the overall poor quality of studies produced no validation for such an association. Further, more extensive research on this topic and prospective studies are needed.

Caries risk profiles in Sardinian schoolchildren using Cariogram.

OBJECTIVE: The aim of our study was to assess the caries risk profile in a group of Sardinian schoolchildren and to compare the outcome with their history of caries. MATERIAL AND METHODS: Using the computer-based program "Cariogram", 957 subjects aged 7, 8, and 9 years were enrolled in this cross-sectional study. The children were examined to evaluate dmfs/DMFS and gingival conditions. Data on dietary and oral hygiene habits were collected and saliva was analyzed, including levels of mutans streptococci (MS) and lactobacilli (Lb). Based on the Cariogram profiles, the children were divided into five risk groups in accordance with "chance of avoiding caries". RESULTS: Almost 50% of the children had a low caries risk, while more than a quarter had less than 40% "chance of avoiding caries". A significant linear trend between the five Cariogram categories and dmfs/DMFS was observed in the three age groups (p<0.001). CONCLUSIONS: The Cariogram risk profile showed strong correlations to the caries experience of Sardinian schoolchildren and that efforts to reduce caries risk are necessary.
