ObjectiveTo test the hypothesis that enterovirus meningitis (EM) is a frequent and self-limiting condition, the epidemiology of EM in adults was examined.MethodsUsing a prospective, nationwide, population-based database, all adults with EM confirmed by PCR of the CSF from 2015 to 2019 were included. Unfavorable outcome was defined as Glasgow Outcome Scale scores of 1–4 at discharge. Modified Poisson regression was used to compute adjusted relative risks (RRs).ResultsA total of 419 cases of EM in 418 adults (46% female, median age 31 years [interquartile range (IQR) 27–35]) yielded an incidence of 1.80/100,000/year. Admission diagnoses included CNS infection 247/397 (62%), other neurologic conditions 89/397 (22%), and cerebrovascular diseases 33/397 (8%). Genotype was available for 271 cases, of which echovirus 30 accounted for 155 (57%). Patients presented with headache 412/415 (99%), history of fever 303/372 (81%), photophobia 292/379 (77%), and neck stiffness 159/407 (39%). Fever (≥38.0°C) was observed in 192/399 (48%) at admission. The median CSF leukocyte count was 130 106/L (range 0–2,100) with polymorphonuclear predominance (>50%) in 110/396 (28%). Cranial imaging preceded lumbar puncture in 127/417 (30%) and was associated with non-CNS infection admission diagnoses and delayed lumbar puncture (median 4.8 hours [IQR 3.4–7.9] vs 1.5 [IQR 0.8–2.8], p < 0.001). Unfavorable outcome occurred in 99/419 (24%) at discharge; more often in female patients (RR 2.30 [1.58–3.33]) and less frequent in echovirus 30 (RR 0.67 [0.46–1.00]) in adjusted analyses. Outcome remained unfavorable in 22/379 (6%) after 6 months.ConclusionsEM is common among young, healthy adults. Although the long-term prognosis remains reassuring, a substantial proportion have moderate disability at discharge, especially female patients.

International audience; Background. Non-polio enteroviruses (EVs) and human parechoviruses (PeVs) cause a wide range of human infections. Limited data on their true disease burden exist as standardized European-wide surveillance is lacking. Aims. Our aim is to estimate the disease burden of EV and PeV infections in Europe via establishment of standardized surveillance for hand, foot and mouth disease (HFMD) and respiratory and neurological infections caused by these viruses. We will also assess the sensitivity of assays implemented in the network of participating laboratories so that all EV and PeV types are adequately detected. Plan. The European Non-Polio Enterovirus Network (ENPEN) has developed standardized protocols for a prospective, multi-center and cross-sectional hospital-based pilot study. Protocols include guidance for diagnosis, case definition, detection, characterization and reporting of EV and PeV infections associated with HFMD and respiratory and neurological diseases. Over 30 sites from 17 European countries have already registered to this one pilot study, likely to be commenced in 2022. Benefits. This surveillance will allow European-wide comparison of data on EV and PeV infection. These data will also be used to determine the burden of EV and PeV infections, which is needed to guide the further prevention measures and policies.

Summary Background Enteroviruses can cause severe infections, especially in young children. Non-polio enterovirus infections are not notifiable in most countries in the EU and European Economic Area (EEA) region, and surveillance varies substantially between countries. We collected and analysed available enterovirus data across EU and EEA countries to assess the current epidemiological situation and need for standardising surveillance. Methods Aggregated data on any enterovirus detected between Jan 1, 2015, and Dec 31, 2017, through national enterovirus reference laboratories were requested from representatives in all 31 EU and EEA countries. Information collected included enterovirus types detected by month, patient age group, symptom, and specimen type. We also collected sequence data on viral capsid sequences for the three most clinically relevant enterovirus types, as identified from the data. Findings Aggregated data were provided by representatives from 24 (77%) of 31 countries. 9914 (66%) of 14 999 enterovirus infections with information about age were in children younger than 5 years, and 3197 (45%) of 7139 individuals for whom symptoms were reported had neurological symptoms. Other symptoms were non-specific fever (in 1607 [23%] patients), respiratory symptoms (in 1197 [17%] patients), hand, foot, and mouth disease (in 528 [7% patients), and myocarditis (in 39 [1%] patients). 68 deaths were temporally associated with enterovirus infection. Typing for 11 559 (67%) of 17 136 specimens revealed 66 enterovirus types. Coxsackievirus A6 was the most frequently detected enterovirus type (in 1556 [13%] of 11 559 typed enteroviruses), and 292 (65%) of 448 patients with coxsackievirus A6 infection with available clinical data presented with hand, foot, and mouth disease. Echovirus 30 was the second most frequently detected enterovirus type, representing 1412 (12%) of 11 559 typed enteroviruses, and 384 (82%) of 467 individuals with echovirus 30 infection with available clinical data had neurological symptoms. Sequences available from 18 countries showed circulation of newly emerging strains of enterovirus A71 and enterovirus D68. Interpretation To our knowledge, this study is the largest investigation of enterovirus circulation in EU and EEA countries and confirms the availability of non-polio enterovirus data in the region. Our study highlights the wide circulation of non-polio enteroviruses in Europe, mostly affecting young children and leading to neurological symptoms. Collecting data on morbidity and mortality related to enterovirus infections, as well as harmonising case definition for surveillance, should be encouraged. Funding None.

Background The long-term clinical course of patients with an enterovirus central nervous system infection (ECI) is poorly understood. Methods We performed a nationwide population-based cohort study of all Danish patients with ECI diagnosed 1997–2016 (n = 1745) and a comparison cohort from the general population individually matched on date of birth and sex (n = 17 450). Outcomes were categorized into mortality and risk of cancer and likely measures of neurological sequelae: neuropsychiatric morbidities, educational landmarks, use of hospital services, employment, receipt of disability pension, income, number of sick leave days, and nursing home residency. Results Mortality in the first year was higher among patients with ECI (mortality rate ratio [MRR] = 10.0; 95% confidence interval [CI], 4.17–24.1), but thereafter mortality was not higher (MMR = 0.94; 95% CI, 0.47–1.86). Long-term outcomes for patients with ECI were not inferior to those of the comparison cohort for risk of cancer, epilepsy, mental and behavioral disorders, dementia, depression, school start, school marks, high school education, use of hospital services, employment, receipt of disability pension, income, days of sick leave, or nursing home residency. Conclusions Diagnosis of an ECI had no substantial impact on long-term survival, health, or social/educational functioning.

Objectives This study was performed to determine the seroprevalence and incidence of hepatitis E virus (HEV) infection among HIV-infected women during pregnancy and after delivery in a cohort of 200 Tanzanian women. Methods HIV-infected women participating in a study on antiretroviral therapy for the prevention of mother-to-child HIV transmission between 2006 and 2011, were tested retrospectively for anti-HEV immunoglobulin G (IgG) in plasma samples at 9 months post-partum. Anti-HEV IgG-positive patients were tested for anti-HEV IgG and immunoglobulin M (IgM) in samples from enrolment, and seroconverting women were tested for HEV RNA. Results A total of 16 women were anti-HEV IgG-positive, two of whom had seroconverted between enrolment and 9 months post-partum, with no detection of anti-HEV IgM or HEV RNA, yielding an HEV seroprevalence of 8.0% (confidence interval 5.0–12.6%) and an annual incidence rate of 1.0% (confidence interval 0.2–3.4%). CD4 cell counts were relatively high (median 403 × 106/l), with no significant difference between women with and without serological signs of HEV. Conclusions An annual HEV infection incidence rate of 1% strongly indicates ongoing transmission of HEV in Tanzania and should be kept in mind for pregnant women presenting with signs of acute hepatitis.

Human parechovirus (HPeV) is a cause of severe morbidity among infants and young children. To evaluate the associations between early environmental risk factors and HPeV infections, we carried out a nationwide cohort study linking registry data on birth and sibship characteristics with a laboratory surveillance database, covering all HPeV infections detected in Denmark during 2009-2012 among children

Background: Hepatitis E virus (HEV) genotype 3 is endemic in Europe, and the infection is mostly subclinical or acute and self-limiting. However, persistent infection is described among HIV-infected individuals. The prevalence of antibodies against HEV (anti-HEV) among HIV-infected persons varies geographically and is unknown in Denmark. Rates of co-infection with HEV among HIV-infected individuals in Denmark over three decades, from the early 1980s to 2013, were investigated. Methods: A total of 2506 HIV-infected persons were investigated from two cohorts followed at Hvidovre Hospital, Denmark. Blood samples were tested retrospectively for anti-HEV, including samples from 2216 persons who were enrolled in a prospective clinical cohort and followed between 1995 and 2013, as well as samples from 290 persons from a historical cohort followed between 1980 and 1994. For anti-HEV seroconverting individuals, serial samples were tested for HEV RNA. Factors associated with anti-HEV status were explored using multivariable logistic regression analysis. Results: The overall HEV seroprevalence rates were stable during the 1980s, 1990s, and 2000–2013 (23.1%, 22.9%, and 23.7%, respectively). In all decades, rates of anti-HEV increased with older age, and anti-HEV seropositivity was associated with older generations, HIV risk group, and geographic origin. Persistent HEV infection was not detected in any of 57 individuals with anti-HEV seroconversion. Conclusions: HEV seroprevalence rates were stable in HIV-infected individuals from the early 1980s to 2013. Rates increased with age. No evidence of persistent HEV infection was detected. Infection with HEV is frequent, but persistent HEV infection is rare among HIV-infected individuals. Keywords: Hepatitis E virus, HEV, Prevalence, HIV, Persistent HEV RNA

Free PMC Article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6205254/ Between 1 June 2016 and 31 May 2017, 17 European Union (EU) and European Economic Area countries reported 4,096 cases associated with a multi-country hepatitis A (HA) outbreak. Molecular analysis identified three co-circulating hepatitis A virus (HAV) strains of genotype IA: VRD_521_2016, V16-25801 and RIVM-HAV16-090. We categorised cases as confirmed, probable or possible, according to the EU outbreak case definitions. Confirmed cases were infected with one of the three outbreak strains. We investigated case characteristics and strain-specific risk factors for transmission. A total of 1,400 (34%) cases were confirmed; VRD_521_2016 and RIVM-HAV16-090 accounted for 92% of these. Among confirmed cases with available epidemiological data, 92% (361/393) were unvaccinated, 43% (83/195) travelled to Spain during the incubation period and 84% (565/676) identified as men who have sex with men (MSM). Results depict an HA outbreak of multiple HAV strains, within a cross-European population, that was particularly driven by transmission between non-immune MSM engaging in high-risk sexual behaviour. The most effective preventive measure to curb this outbreak is HAV vaccination of MSM, supplemented by primary prevention campaigns that target the MSM population and promote protective sexual behaviour. info:eu-repo/semantics/publishedVersion

SUMMARYRotavirus (RV) infections affect young children, but can also occur in adults. We sought to identify risk factors for RV infections in adults aged ⩾18 years in Denmark, and to describe illness and genotyping characteristics. From March 2005 to February 2009, we recruited consecutive cases of laboratory-confirmed RV infection and compared them with healthy controls matched by age, gender and municipality of residence. We collected information on illness characteristics and exposures using postal questionnaires. We calculated univariable and multivariable matched odds ratios (mOR) with conditional logistic regression. The study comprised 65 cases and 246 controls. Illness exceeded 10 days in 31% of cases; 22% were hospitalized. Cases were more likely than controls to suffer serious underlying health conditions [mOR 5·6, 95% confidence interval (CI) 1·7–18], and to report having had close contact with persons with gastrointestinal symptoms (mOR 9·4, 95% CI 3·6–24), in particular young children aged 18 years. Close contact with young children or adults with gastrointestinal symptoms is the main risk factor for RV infection in adults in Denmark. RV vaccination assessments should consider that RV vaccination in children may indirectly reduce the burden of disease in adults.

From January to June 2018, two ongoing hepatitis A outbreaks affected travellers returning from Morocco and cases in Europe without travel history, resulting in 163 patients in eight European countries. Most interviewed travel-related cases were unaware of the hepatitis A risk in Morocco. Molecular analysis revealed two distinct hepatitis A virus (HAV) strains (subgenotype IA DK2018_231; subgenotype IB V18-16428). Vaccination recommendations should be emphasised to increase awareness among non-immune travellers to Morocco and HAV-endemic countries. First, we thank the European Centre for Disease Prevention and Control (ECDC)’s Food- and Waterborne Diseases and Zoonoses team, particularly Ettore Severi and Johanna Takkinen for their support of this joint investigation. We also thank Lelia Thornton, HSE - Health Protection Surveillance Centre, Dublin, Ireland for sharing information on the Irish hepatitis A patient. Moreover, we greatly acknowledge the work of local and state health departments for their support of epidemiological investigations and molecular surveillance. Sí

We describe a rare case of hepatitis A virus (HAV) replication in feces despite presence of hepatitis A antibodies in an acute myeloid leukemia (AML) patient after transfusion with HAV contaminated platelets. The patient has been vaccinated against HAV years before the AML diagnosis. Transient infection and reshedding should thus be considered in antibody-positive hematological patients. Transfusion associated HAV transmission is rare, and little evidence exists on the clinical consequences and possible effect of treatment with immunoglobulin. Further reporting on fecal shedding despite antibodies are needed, as HAV antibody levels are used as course of action for post-exposure prophylaxis and infection control.

AIMS: To investigate seasonality and association of increased enterovirus and influenza activity in the community with ventricular fibrillation (VF) risk during first ST-elevation myocardial infarction (STEMI).METHODS: This study comprised all consecutive patients with first STEMI (n = 4,659; aged 18-80 years) admitted to the invasive catheterization laboratory between 2010-2016, at Copenhagen University Hospital, Rigshospitalet, covering eastern Denmark (2.6 million inhabitants, 45% of the Danish population). Hospital admission, prescription, and vital status data were assessed using Danish nationwide registries. We utilized monthly/weekly surveillance data for enterovirus and influenza from the Danish National Microbiology Database (2010-2016) that receives copies of laboratory tests from all Danish departments of clinical microbiology.RESULTS: Of the 4,659 consecutively enrolled STEMI patients, 581 (12%) had VF before primary percutaneous coronary intervention. In a subset (n = 807), we found that VF patients experienced more generalized fatigue and flu-like symptoms within 7 days before STEMI compared with the patients without VF (OR 3.39, 95% CI 1.76-6.54). During the study period, 2,704 individuals were diagnosed with enterovirus and 19,742 with influenza. No significant association between enterovirus and VF (OR 1.00, 95% CI 0.99-1.02), influenza and VF (OR 1.00, 95% CI 1.00-1.00), or week number and VF (p-value 0.94 for enterovirus and 0.89 for influenza) was found.CONCLUSION: We found no clear seasonality of VF during first STEMI. Even though VF patients had experienced more generalized fatigue and flu-like symptoms within 7 days before STEMI compared with patients without VF, no relationship was found between enterovirus or influenza exposure and occurrence of VF.

Infections with human parechoviruses (HPeVs) are highly prevalent, particularly in neonates, where they may cause substantial morbidity and mortality. The clinical presentation of HPeV infection in neonates is indistinguishable from that of enterovirus (EV) infection and may vary from mild disease involving gastrointestinal and/or respiratory symptoms to more severe illness with sepsis-like symptoms such as fever, seizures, irritability, rash and/or feeding problems. HPeV is among the most common single causes of aseptic meningitis/meningoencephalitis in infants

The primary aim of the Danish enterovirus (EV) surveillance system is to document absence of poliovirus infection. The conflict in Syria has left many children unvaccinated and movement from areas with polio cases to Europe calls for increased awareness to detect and respond to virus-transmission in a timely manner. We evaluate the national EV laboratory surveillance, to generate recommendations for system strengthening. The system was analysed for completeness of viral typing analysis and clinical information and timeliness of specimen collection, laboratory results and reporting of clinical information. Of 23,720 specimens screened, 2,202 (9.3%) were EV-positive. Submission of cerebrospinal fluid and faecal specimens from primary diagnostic laboratories was 79.5% complete (845/1,063), and varied by laboratory and patient age. EV genotypes were determined in 68.5% (979/1,430) of laboratory-confirmed cases, clinical information was available for 63.1% (903/1,430). Primary diagnostic results were available after a median of 1.4 days, typing results after 17 days, detailed clinical information after 33 days. The large number of samples typed demonstrated continued monitoring of EV-circulation in Denmark. The system could be strengthened by increasing the collection of supplementary faecal specimens, improving communication with primary diagnostic laboratories, adapting the laboratory typing methodology and collecting clinical information with electronic forms.

Summary Since its discovery in California in 1962, reports of enterovirus D68 have been infrequent. Before 2014, infections were confirmed in only 699 people worldwide. In August, 2014, two paediatric hospitals in the USA reported increases in the number of patients with severe respiratory illness, with an over-representation in children with asthma. Shortly after, the authorities recognised a nationwide outbreak, which then spread to Canada, Europe, and Asia. In 2014, more than 2000 cases of enterovirus D68 were reported in 20 countries. Concurrently, clusters of children with acute flaccid paralysis of unknown cause were reported in several US states and in Europe. Enterovirus D68 infection was confirmed in some of the paralysed children, but not all. Complications in patients who were severely neurologically affected resemble those caused by poliomyelitis. In this paper we systematically review reports on enterovirus D68 to estimate its global epidemiology and its ability to cause respiratory infections and neurological damage in children. We extracted data from 70 papers to report on prevalence, symptoms, hospitalisation and mortality, and complications of enterovirus D68, both before and during the large outbreak of 2014. The magnitude and severity of the enterovirus D68 outbreak underscores a need for improved diagnostic work-up of paediatric respiratory illness, not only to prevent unnecessary use of antibiotics, but also to ensure better surveillance of diseases. Existing surveillance systems should be assessed in terms of capacity and ability to detect and report any upsurge of respiratory viruses such as enterovirus D68 in a timely manner, and focus should be paid to development of preventive measures against these emerging enteroviruses that have potential for severe disease.

Since the late 1990s enterovirus 71 (EV71) has caused epidemics of hand, foot and mouth disease with fatal cases especially in the Asian Pacific region. The objective of this study was to describe the clinical and virological features of EV71 infections in Denmark.All enterovirus-positive samples in Denmark are submitted to the National Poliovirus Laboratory for typing, and the EV71-positive samples are characterized by sequencing and phylogenetic analysis. Clinical information was gathered for the EV71-positive patients.During 2005-2008, EV71 was demonstrated in 29 patients. In 2007 EV71 was the second most common enterovirus type detected in Denmark. Twenty-one of the 29 patients were children aged ≤1 y, 24 were hospitalized, and meningitis was the most common diagnosis. Gastroenteritis and hand, foot and mouth disease were other common clinical manifestations, but no fatal cases or cases of pulmonary oedema were seen. A novel subgenotype in Europe, B5, dominated the 2007 outbreak, but co-circulated with subgenotypes C1 and C2.In conclusion EV71 was among the common enterovirus types in Denmark, and in 2007 a novel subgenotype, B5, was observed. EV71 was mainly diagnosed in infants, and the majority of patients were hospitalized with meningitis.

BACKGROUND: Hepatitis E virus genotype-3 (HEV-gt-3) causes autochthonous infections in western countries, with a primary reservoir in animals, especially pigs. HEV transfusion transmission has been reported, and HEV-gt-3 prevalence is high in some European countries. The prevalence of HEV RNA was investigated among Danish blood donors, and the prevalence of HEV transfusion-transmitted infection (TTI) was investigated among recipients.STUDY DESIGN AND METHODS: Samples from 25,637 consenting donors collected during 1 month in 2015 were screened retrospectively using an individual-donation HEV RNA nucleic acid test with a 95% detection probability of 7.9 IU/mL. HEV-positive samples were quantified by real-time polymerase chain reaction and genotyped. Transmission was evaluated among recipients of HEV RNA-positive blood components. Phylogenetic analyses compared HEV sequences from blood donors, symptomatic patients, and swine.RESULTS: Eleven donations (0.04%) were confirmed as positive for HEV RNA (median HEV RNA level, 13 IU/mL). Two donations were successfully genotyped as HEV-gt-3. Only one donor had a travel history outside Europe. Nine of 11 donors were male, but the gender ratio was nonsignificant compared with the total donor population. Seven available recipients tested negative for HEV RNA and anti-HEV immunoglobulin M in follow-up samples. One recipient was HEV RNA-negative but anti-HEV immunoglobulin G-positive. HEV TTI was considered unlikely, but a transfusion-induced secondary immune response could not be excluded. Phylogenetic analysis showed relatively large sequence differences between HEV from donors, symptomatic patients, and swine.CONCLUSIONS: Despite an HEV RNA prevalence of 0.04% in Danish blood donations, all HEV-positive donations carried low viral loads, and no evidence of TTI was found.

A food-borne outbreak of hepatitis A in Denmark was notified to other countries on 1 March 2013. A case-control study identified frozen berries eaten in smoothies as potential vehicle. In the following weeks, Finland, Norway and Sweden also identified an increased number of hepatitis A patients without travel history. Most cases reported having eaten frozen berries at the time of exposure. By 17 April, 71 cases were notified in the four countries. No specific type of berry, brand or origin of berries has yet been identified. .

Since November 2012, there has been an increase in reported cases of hepatitis A in tourists returning from Egypt in several European countries. As of 24 April, 80 HAV cases in travellers with symptom onset after 1 November 2012 visiting different areas in Egypt have been reported. Four cases from Norway, six cases from the Netherlands and five cases from England share an identical hepatitis A viral RNA sequence. This increase in cases suggests that vaccination recommendations for travellers to hepatitis A endemic countries should be reinforced.

Group A rotaviruses can infect both humans and animals. Individual rotavirus strains can occasionally cross species barriers and might hereby contribute to the emergence of new genotypes in heterologous hosts. The incidence and impact of zoonotic rotavirus are not well defined, and one reason for this is a lack of data about strains circulating in suspected reservoir animal hosts. In this study we report the incidence, genetic diversity, and molecular epidemiology of rotaviruses detected in domestic cattle and swine in 6 European countries. From 2003 to 2007, 1101 and more than 2000 faecal specimens were collected from swine and cattle, both healthy and diarrhoeic, and tested for rotaviruses. Viruses from positive stools were genotyped and a subset of strains was characterized by nucleotide sequencing and phylogenetic analysis of the VP7 (G) and VP4 (P) genes. Rotaviruses were detected in 43% of bovine samples and in 14% of porcine samples. In cattle, 10 different combinations of G and P types were identified and the most common strains were G6P[11] and G6P[5]. In swine, the number of identified G-P combinations was higher (n=21), however, no single combination was predominant across Europe. Newly described genotype specificities, P[27] and P[32], were identified in swine. When compared at the nucleotide sequence level, the identified porcine rotavirus strains and contemporary human strains grouped together phylogenetically, whereas bovine rotavirus strains formed separate clades. These data demonstrate large genetic diversity of porcine and bovine rotavirus strains across Europe, and suggest that livestock herds may serve as potential reservoirs for human infections.

Acute flaccid myelitis; Enterovirus D68; Surveillance Mielitis flàcida aguda; Enterovirus D68; Vigilància Mielitis flácida aguda; Enterovirus D68; Vigilancia We report a rapid increase in enterovirus D68 (EV-D68) infections, with 139 cases reported from eight European countries between 31 July and 14 October 2021. This upsurge is in line with the seasonality of EV-D68 and was presumably stimulated by the widespread reopening after COVID-19 lockdown. Most cases were identified in September, but more are to be expected in the coming months. Reinforcement of clinical awareness, diagnostic capacities and surveillance of EV-D68 is urgently needed in Europe.

Enteroviruses (EV) can cause severe neurological and respiratory infections, and occasionally lead to devastating outbreaks as previously demonstrated with EV-A71 and EV-D68 in Europe. However, these infections are still often underdiagnosed and EV typing data is not currently collected at European level. In order to improve EV diagnostics, collate data on severe EV infections and monitor the circulation of EV types, we have established European non-polio enterovirus network (ENPEN). First task of this cross-border network has been to ensure prompt and adequate diagnosis of these infections in Europe, and hence we present recommendations for non-polio EV detection and typing based on the consensus view of this multidisciplinary team including experts from over 20 European countries. We recommend that respiratory and stool samples in addition to cerebrospinal fluid (CSF) and blood samples are submitted for EV testing from patients with suspected neurological infections. This is vital since viruses like EV-D68 are rarely detectable in CSF or stool samples. Furthermore, reverse transcriptase PCR (RT-PCR) targeting the 5'noncoding regions (5'NCR) should be used for diagnosis of EVs due to their sensitivity, specificity and short turnaround time. Sequencing of the VP1 capsid protein gene is recommended for EV typing; EV typing cannot be based on the 5'NCR sequences due to frequent recombination events and should not rely on virus isolation. Effective and standardized laboratory diagnostics and characterisation of circulating virus strains are the first step towards effective and continuous surveillance activities, which in turn will be used to provide better estimation on EV disease burden. ispartof: Journal of Clinical Virology vol:101 pages:11-17 ispartof: location:Netherlands status: published

From June 2014 through February 2015, respiratory samples from 130 Danish patients were screened for enterovirus D68 (EV-D68). Fourteen EV-D68 cases were detected, of which 12 presented with respiratory symptoms, and eight had known underlying disease. The median age of EV-D68 cases was three years (interquartile range: 0–30 years). Acute flaccid paralysis (AFP) was not detected although Danish EV-D68 strains showed > 98% nt identity with EV-D68-strains from AFP cases from the United States and France.
