Epidemic of parvovirus B19 and disease severity in pregnant people, Denmark, January to March 2024.

We report an epidemic of parvovirus B19 infections in Denmark during the first quarter of 2024, with a peak incidence 3.5 times higher than during the most recent epidemic in 2017. In total, 20.1% (130/648) of laboratory-confirmed cases were pregnant. Severe adverse outcomes were observed among 12.3% (16/130) of pregnant people and included foetal anaemia, foetal hydrops and miscarriage. Parvovirus B19 infection is not systematically monitored, but a national laboratory-based surveillance system is currently being established in Denmark.

Factors associated with the formation of SARS-CoV-2 case-clusters in Danish schools: a nationwide register-based observational study.

A register-based retrospective observational study was conducted to describe SARS-CoV-2 cases and case-clusters in schoolchildren of Danish primary and lower secondary schools and identify which factors were associated with the occurrence of case-clusters in schools. The study period was the autumn school semester 2021. Clusters were defined as three or more cases in a school-class level within 14 days. Descriptive analysis was carried out and multivariable logistic regression analysis was performed to determine which factors were associated with case introductions (i.e., primary case) being linked to a cluster. More cases and clusters were identified in lower than in higher class levels. Out of 21,497 cases introduced into a school, 41.6% started a cluster. A higher assumed immunity level in a class level was significantly reducing the odds of a case introduction being linked to a cluster (e.g., assumed immunity of ≥80% vs <20%: OR: 0.28; 95%CI: 0.17-0.44). A previous infection (in the primary case) had a protective effect (OR: 0.58; 95%CI: 0.33-0.99). This study suggests that most cases appearing in schools did not induce clusters, but that once cluster occur sizes can be large. It further indicates that vaccination of children markedly reduces the risk of secondary infections.

Increase in invasive group A streptococcal infections and emergence of novel, rapidly expanding sub-lineage of the virulent Streptococcus pyogenes M1 clone, Denmark, 2023.

A highly virulent sub-lineage of the Streptococcus pyogenes M1 clone has been rapidly expanding throughout Denmark since late 2022 and now accounts for 30% of the new invasive group A streptococcal infections. We aimed to investigate whether a shift in variant composition can account for the high incidence rates observed over winter 2022/23, or if these are better explained by the impact of COVID-19-related restrictions on population immunity and carriage of group A Streptococcus.

Findings in Danish long-term care facilities in the first year of the SARS-CoV-2 pandemic.

PURPOSE: To describe the occurrence of SARS-CoV-2 infections, deaths and outbreaks among residents in Danish long-term care facilities (LTCFs) from February 2020 to February 2021. METHODS: Danish COVID-19 national register data from a newly implemented automated surveillance system was used to describe incidence rate and deaths (per 1000 residents' years), number of tests, SARS-CoV-2 infections and outbreaks among LTCF residents. A case was defined as a LTCF resident with a positive SARS-CoV-2 PCR test. An outbreak was defined as two or more cases in one LTCF within a 14-day period, and considered closed if no new cases had occurred within 28 days. Death was defined as occurring within 30-days of a positive test. RESULTS: A total of 55,359 residents living in 948 LTCFs were included. The median age of the residents was 85 years and 63% were female. There was a total of 3712 cases found among residents across 43% of all LTCFs. Nearly all (94%) cases were linked to outbreaks. Higher numbers of cases and outbreaks were seen in Denmark's Capital Region compared to other regions. Overall, 22 SARS-CoV-2 deaths and 359 deaths (non-SARS-CoV-2) per 1000 resident years were identified in the study period. CONCLUSION: Less than half of LTCFs identified any cases. The majority of cases were linked to outbreaks, emphasizing the importance of preventing introductions of SARS-CoV-2 into the facilities. Furthermore, it highlights the need to invest efforts into infrastructures, routine procedures and monitoring of SARS-CoV-2 in LTCFs to limit the introduction and the spread of SARS-CoV-2.

Age-specific associations between underlying health conditions and hospitalisation, death and in-hospital death among confirmed COVID-19 cases: a multi-country study based on surveillance data, June to December 2020.

BackgroundUnderlying conditions are risk factors for severe COVID-19 outcomes but evidence is limited about how risks differ with age.AimWe sought to estimate age-specific associations between underlying conditions and hospitalisation, death and in-hospital death among COVID-19 cases.MethodsWe analysed case-based COVID-19 data submitted to The European Surveillance System between 2 June and 13 December 2020 by nine European countries. Eleven underlying conditions among cases with only one condition and the number of underlying conditions among multimorbid cases were used as exposures. Adjusted odds ratios (aOR) were estimated using 39 different age-adjusted and age-interaction multivariable logistic regression models, with marginal means from the latter used to estimate probabilities of severe outcome for each condition-age group combination.ResultsCancer, cardiac disorder, diabetes, immunodeficiency, kidney, liver and lung disease, neurological disorders and obesity were associated with elevated risk (aOR: 1.5-5.6) of hospitalisation and death, after controlling for age, sex, reporting period and country. As age increased, age-specific aOR were lower and predicted probabilities higher. However, for some conditions, predicted probabilities were at least as high in younger individuals with the condition as in older cases without it. In multimorbid patients, the aOR for severe disease increased with number of conditions for all outcomes and in all age groups.ConclusionWhile supporting age-based vaccine roll-out, our findings could inform a more nuanced, age- and condition-specific approach to vaccine prioritisation. This is relevant as countries consider vaccination of younger people, boosters and dosing intervals in response to vaccine escape variants.

Translating health information into policy-making: A pragmatic framework.

Knowledge translation (KT) is increasingly acknowledged to have the potential to improve policy-making. The value of health information (HI), as part of the KT context, is now also increasingly understood. This paper aims to identify existing tools for the translation of HI into policy-making and to develop a related framework facilitating future application of these identified tools. Updating and building upon a scoping review undertaken for the Health Evidence Network (HEN) Synthesis Report No. 54, commissioned by the World Health Organization (WHO) Regional Office for Europe in 2017, a literature search was conducted using the same databases (PubMed and Scopus) and the same keywords as in the WHO/HEN scoping review. All papers elaborating on tools enhancing the use of HI in policy-making were included. Of the 2549 records screened, 17 publications were included in this study. This review identified four different types of tools: 1) Visualisation and modelling tools, 2) Information packaging and synthesis tools, 3) Communication and dissemination tools and 4) Information linkage and exchange tools. The distinctions between these are fluid as different tools can be combined or incorporated into one another to complement each other. Our framework shows that communication/dissemination or linkage tools are crucial to effectively inform policy decisions through HI. This study helps to understand and guide the processes of KT of HI.

Epidemiological characterisation of the first 785 SARS-CoV-2 Omicron variant cases in Denmark, December 2021.

By 9 December 2021, 785 SARS-CoV-2 Omicron variant cases have been identified in Denmark. Most cases were fully (76%) or booster-vaccinated (7.1%); 34 (4.3%) had a previous SARS-CoV-2 infection. The majority of cases with available information reported symptoms (509/666; 76%) and most were infected in Denmark (588/644; 91%). One in five cases cannot be linked to previous cases, indicating widespread community transmission. Nine cases have been hospitalised, one required intensive care and no deaths have been registered.

Characteristics of SARS-CoV-2 variants of concern B.1.1.7, B.1.351 or P.1: data from seven EU/EEA countries, weeks 38/2020 to 10/2021.

We compared 19,207 cases of SARS-CoV-2 variant B.1.1.7/S gene target failure (SGTF), 436 B.1.351 and 352 P.1 to non-variant cases reported by seven European countries. COVID-19 cases with these variants had significantly higher adjusted odds ratios for hospitalisation (B.1.1.7/SGTF: 1.7, 95% confidence interval (CI): 1.0-2.9; B.1.351: 3.6, 95% CI: 2.1-6.2; P.1: 2.6, 95% CI: 1.4-4.8) and B.1.1.7/SGTF and P.1 cases also for intensive care admission (B.1.1.7/SGTF: 2.3, 95% CI: 1.4-3.5; P.1: 2.2, 95% CI: 1.7-2.8).

'I also take part in caring for the sick child': a qualitative study on fathers' roles and responsibilities in seeking care for children in Southwest Ethiopia.

OBJECTIVES: Fathers play an important role in household decision-making processes and child health development. Nevertheless, they are under-represented in child health research, especially in low-income settings. Little is known about what roles fathers play in the care-seeking processes or how they interact with the health system when their child is sick. This study aimed to understand Ethiopian fathers' roles and responsibilities in caring for their children when they are or become ill. DESIGN: Qualitative study using semistructured interviews with fathers. SETTING: This study was conducted in three rural districts of the Southern Nations, Nationalities and People's Region of Ethiopia. PARTICIPANTS: Twenty-four fathers who had at least one child between 2 and 59 months who visited a health extension worker with fever. RESULTS: The overarching theme of this study was 'changing perceptions of paternal responsibilities during children's ill health'. It constituted three subthemes, namely, 'fathers' burden of earning money for care', 'fatherhood entails advocating children's healthcare needs' and 'investing in children's health can benefit the family in the future'. Fathers described that they were the ones mainly responsible for the financial arrangement of care and that this financial responsibility can involve stress when resources are scarce. Fathers knew what health services were available and accessible to them and were involved in different ways in the care seeking of the child. Changes in the importance ascribed to child health were expressed by fathers who described being more alert to children's ill-health. CONCLUSION: Fathers play various roles in the care-seeking process during children's illness episodes. This included, for instance, arranging resources to seek care, (co)-deciding where to seek care as well as accompanying the child to the health facility. The inability to organise necessary resources for care can lead to involuntary delays in care seeking for the child. This demonstrates the importance of including fathers in future interventions on maternal and child health.

Noma-knowledge and practice competence among primary healthcare workers: a cross-sectional study in Burkina Faso.

BACKGROUND: Noma is a quickly progressing, neglected opportunistic infection. It starts in the mouth as an oral lesion but can relatively quickly develop into extensive facial destruction and lead to death if not treated in time. This study aims to shed light on primary healthcare workers' practice competences in working with and knowledge of noma. METHODS: A structured questionnaire using questions and case scenarios was filled out by 76 healthcare workers in Burkina Faso. Half of the nurses included in this study participated in a 2-day noma training. Data were analysed descriptively and Fisher's exact test was used to study differences between occupational groups using Stata. RESULTS: Most healthcare workers reported having examined the mouth of children with diseases predisposing to noma. The total practice competence was poor, with almost 70% having suboptimal or very low competences. However, competences varied between different stages of noma disease. Knowledge scores varied between occupational groups. The majority of nurses and odontostomatology specialist nurses had optimal or good knowledge of noma. Significant differences in knowledge and practice competence were found between nurses who attended a 2-day training course on noma and those who did not. CONCLUSIONS: Health care workers in this study had quite poor practice competences in managing noma. The knowledge scores of these health workers were moderate. It is important for healthcare workers to be able to identify noma patients at an early stage, as at this point the disease can still be completely reversed.

Management and Follow-up Practices of Children with Unclassified Fever in Rural Ethiopia: Experiences of Health Extension Workers and Caregivers.

Different health-care management guidelines by the World Health Organization exist to help health workers in resource-limited settings treat patients. However, for children with unclassified fever and no danger signs, management guidelines are less clear and follow-up recommendations differ. Both a "universal follow-up" for all children, irrespective of health status, and a "conditional follow-up" only for children whose fever persists are recommended in different guidelines. It is unclear how feasible and acceptable these two different follow-up guidelines are among community health workers and caregivers of the sick child. This qualitative study was conducted in Ethiopia and was nested within a cluster-randomized controlled trial (cRCT). It aimed to determine health extension workers' (HEWs') and caregivers' experiences of the management of febrile children and their perceptions of universal versus conditional follow-up recommendations. Seventeen HEWs and 20 caregivers were interviewed. The interviews revealed that HEWs' understanding of how to handle an unclassified fever diagnosis increased with the implementation of the cRCT in both study arms (universal versus conditional follow-up). This enabled HEWs to withhold medicines from children with this condition and avoid referral to health centers. Both follow-up recommendations had perceived advantages, while the universal follow-up provided an opportunity to see the child's health progress, the conditional follow-up advice allowed saving time and costs. The findings suggest that improved awareness of the unclassified fever condition can make HEWs feel more comfortable in managing these febrile children themselves and omitting unnecessary medication. Future community-level management guidelines should provide clearer instructions on managing fever where no malaria, pneumonia, diarrhea, or danger signs are present.

Universal versus conditional day 3 follow-up for children with non-severe unclassified fever at the community level in Ethiopia: A cluster-randomised non-inferiority trial.

BACKGROUND: With declining malaria prevalence and improved use of malaria diagnostic tests, an increasing proportion of children seen by community health workers (CHWs) have unclassified fever. Current community management guidelines by WHO advise that children seen with non-severe unclassified fever (on day 1) should return to CHWs on day 3 for reassessment. We compared the safety of conditional follow-up reassessment only in cases where symptoms do not resolve with universal follow-up on day 3. METHODS AND FINDINGS: We undertook a 2-arm cluster-randomised controlled non-inferiority trial among children aged 2-59 months presenting with fever and without malaria, pneumonia, diarrhoea, or danger signs to 284 CHWs affiliated with 25 health centres (clusters) in Southern Nations, Nationalities, and Peoples' Region, Ethiopia. The primary outcome was treatment failure (persistent fever, development of danger signs, hospital admission, death, malaria, pneumonia, or diarrhoea) at 1 week (day 8) of follow-up. Non-inferiority was defined as a 4% or smaller difference in the proportion of treatment failures with conditional follow-up compared to universal follow-up. Secondary outcomes included the percentage of children brought for reassessment, antimicrobial prescription, and severe adverse events (hospitalisations and deaths) after 4 weeks (day 29). From December 1, 2015, to November 30, 2016, we enrolled 4,595 children, of whom 3,946 (1,953 universal follow-up arm; 1,993 conditional follow-up arm) adhered to the CHW's follow-up advice and also completed a day 8 study visit within ±1 days. Overall, 2.7% had treatment failure on day 8: 0.8% (16/1,993) in the conditional follow-up arm and 4.6% (90/1,953) in the universal follow-up arm (risk difference of treatment failure -3.81%, 95% CI -∞, 0.65%), meeting the prespecified criterion for non-inferiority. There were no deaths recorded by day 29. In the universal follow-up arm, 94.6% of caregivers reported returning for reassessment on day 3, in contrast to 7.5% in the conditional follow-up arm (risk ratio 22.0, 95% CI 17.9, 27.2, p < 0.001). Few children sought care from another provider after their initial visit to the CHW: 3.0% (59/1,993) in the conditional follow-up arm and 1.1% (22/1,953) in the universal follow-up arm, on average 3.2 and 3.4 days later, respectively, with no significant difference between arms (risk difference 1.79%, 95% CI -1.23%, 4.82%, p = 0.244). The mean travel time to another provider was 2.2 hours (95% CI 0.01, 5.3) in the conditional follow-up arm and 2.6 hours (95% CI 0.02, 4.5) in the universal follow-up arm (p = 0.82); the mean cost for seeking care after visiting the CHW was 26.5 birr (95% CI 7.8, 45.2) and 22.8 birr (95% CI 15.6, 30.0), respectively (p = 0.69). Though this study was an important step to evaluate the safety of conditional follow-up, the high adherence seen may have resulted from knowledge of the 1-week follow-up visit and may therefore not transfer to routine practice; hence, in an implementation setting it is crucial that CHWs are well trained in counselling skills to advise caregivers on when to come back for follow-up. CONCLUSIONS: Conditional follow-up of children with non-severe unclassified fever in a low malaria endemic setting in Ethiopia was non-inferior to universal follow-up through day 8. Allowing CHWs to advise caregivers to bring children back only in case of continued symptoms might be a more efficient use of resources in similar settings.

Management of noma: practice competence and knowledge among healthcare workers in a rural district of Zambia.

BACKGROUND: Noma is an infectious but opportunistic disease that often results in severe facial disfigurements and mortality if untreated. As noma progresses quickly, early detection and treatment are important to prevent its development. OBJECTIVES: The objective of this study was to investigate primary healthcare workers' knowledge and management of noma in a rural part of Zambia. METHODS: A cross-sectional self-completed survey was conducted among 35 healthcare workers from two district hospitals and 15 rural health centres in Serenje District, Zambia. Participants' practice competences and knowledge were grouped into 'optimal', 'medium', 'suboptimal' and 'very low'. RESULTS: Most of the healthcare workers stated that they perform mouth examination of a child below five years of age who is suffering from measles, malnutrition or HIV. A majority diagnosed gingivitis correctly and 40% had a medium level of practice competence of the same noma stage. All participants had a suboptimal or very low level on overall practice competence regarding management of noma and two-thirds had a very low level of reported knowledge. CONCLUSION: General knowledge on noma and competences of diagnosing and treating noma patients was low among healthcare workers. Lack of knowledge could present a barrier for correctly managing noma at an early stage. Improving knowledge among healthcare workers is one way to prevent the development of the disease. In order to prevent noma from the start, actions need to be focussed on improving (oral) hygiene and health education as well. Telemedicine could also be considered as it can help healthcare workers in handling noma patients through enabling communication and exchange of information with specialist.

Policy challenges and reforms in small EU member state health systems: a narrative literature review.

BACKGROUND: The EU directive on patients' rights and cross-border care is of particular interest to small states as it reinforces the concept of health system cooperation. An analysis of the challenges faced by small states, as well as a deep evaluation of their health system reform characteristics is timely and justified. This paper identifies areas in which EU level cooperation may bring added value to these countries' health systems. METHOD: Literature search is based primarily on PUBMED and is limited to English-language papers published between January 2000 and September 2014. Results of 76 original research papers appearing in peer-reviewed journals are summarised in a literature map and narrative review. RESULTS: Primary care, health workforce and medicines emerge as the salient themes in the review. Lack of capacity and small market size are found to be the frequently encountered challenges in governance and delivery of services. These constraints appear to also impinge on the ability of small states to effectively implement health system reforms. The EU appears to play a marginal role in supporting small state health systems, albeit the stimulus for reform associated with EU accession. CONCLUSIONS: Small states face common health system challenges which could potentially be addressed through enhanced health system cooperation at EU level. The lessons learned from research on small states may be of relevance to health systems organized at regional level in larger European states.
