BACKGROUND: Human adenoviruses (HAdV), in particular types 4 and 7, frequently cause acute respiratory disease (ARD) during basic military training. HAdV4 and HAdV7 vaccines reduced the ARD risk in US military. It is important to identify other respiratory pathogens and assess their potential impact on military readiness. METHODS: In 2002, during a period when the HAdV vaccines were not available, throat swabs were taken from trainees (n = 184) with respiratory infections at Fort Jackson, South Carolina...

We describe the presenting features and long-term outcome of an unusual cluster of pediatric acute flaccid paralysis cases that occurred in Canada during the 2014 enterovirus D68 outbreak. Children (n = 25; median age 7.8 years) presenting to Canadian centers between July 1 and October 31, 2014, and who met diagnostic criteria for acute flaccid paralysis were evaluated retrospectively. The predominant presenting features included prodromal respiratory illness (n = 22), cerebrospinal fluid lymphocytic pleocytosis (n = 18), pain in neck/back (n = 14) and extremities (n = 10), bowel/bladder dysfunction (n = 9), focal central gray matter lesions found in all regions of the spinal cord within the cohort (n = 16), brain stem lesions (n = 8), and bulbar symptoms (n = 5)...

BACKGROUND: Enterovirus D68 (EV-D68) has been sporadically reported as a cause of respiratory tract infections. In 2014, an international outbreak of EV-D68 occurred and caused severe respiratory disease in the pediatric population. METHODS: A retrospective chart review was performed of children admitted to Children's Mercy Hospital from August 1, 2014, to September 15, 2014, with positive multiplex polymerase chain reaction testing for EV/rhinovirus (RV). Specimens were subsequently tested for EV-D68, and clinical data were obtained from the medical records...

Causing an international outbreak of respiratory disease, Enterovirus D68 quickly entered the closed circle of emerging viral pathogens of public health significance. As rapid and accurate detection of EV-D68 is essential for an efficient clinical management, we designed and validated a new highly efficient one-step quantitative rRT-PCR specific to EV-D68 VP4-VP2 region. With 100% specificity and 95.6% sensitivity to all EV-D68 strains, this new assay can be reliably used to detect and quantify EV-D68 in respiratory samples and represents an interesting additional tool for diagnosis as it targets an original region of the genome...

Molecular techniques increased the number of documented respiratory infections. In a substantial number of cases the causative agent remains undetected. Since August 2014, an increase in Enterovirus(EV)-D68 infections was reported. We aimed to investigate epidemiology and clinical relevance of EV-D68. From June to December 2014 and from September to December 2015, 803 and 847 respiratory specimens, respectively, were tested for respiratory viruses with a multiplex RT-PCR. This multiplex RT-PCR does not detect EV-D68...

BACKGROUND: During the Fall of 2014, numerous children were hospitalized with asthma or respiratory distress related to Enterovirus D68 (EV-D68). A large proportion initially tested positive for rhinovirus. During this period our laboratory noted a cross-reactivity between EV-D68 and the rhinovirus component of the GenMark multiplex respiratory viral panel. Many other laboratories used assays not designed to distinguish these Picornoviridae. METHODS: To compare the presentation and outcomes of patients with rhinovirus and EV-D68, 103 GenMark rhinovirus positive nasopharyngeal swabs from hospitalized children were retested for EV-D68...

Enteroviruses (EVs) are associated with a broad spectrum of clinical presentation, including aseptic meningitis (AM), encephalitis, hand, foot and mouth disease, acute flaccid paralysis and acute flaccid myelitis. Epidemics occur sporadically and are associated with increased cases of AM in children. The present study describes the seroepidemiological analysis of circulating EVs in Ireland from 2005-2014 and phylogenetic characterisation of echovirus 30 (E-30), enterovirus A71 (EV-A71) and enterovirus D68 (EV-D68)...

Complete genome sequences of nine enterovirus D68 (EV-D68) strains from patients in New York were obtained in 2016 by metagenomic next-generation sequencing. Comparative genomic analysis suggests that a new subclade B3, with ~4.5% nucleotide divergence from subclade B1 strains causing the 2014 outbreak, is circulating in the United States in 2016.

BACKGROUND: Since mid-August 2014, North America experienced a wide outbreak of Enterovirus D68 (EV-D68) associated with severe respiratory illness in children. Several other countries also reported cases of EV-D68 in 2014. OBJECTIVES: The aim of this study was to determine whether EV-D68 circulated in Israel in 2014, caused severe respiratory illness in children and was the causative agent of Acute Flaccid Paralysis. STUDY DESIGN: Archived clinical respiratory samples from a cohort of 710 hospitalized pediatric patient's (<10years old) with respiratory illness were screened for clade B specific EV-D68 by real-time PCR...

Enterovirus D68 (EV-D68) is a member of the Picornaviridae family. Although EV-D68-associated infection was once considered rare, it has been increasing in recent years. EV-D68 infection is most frequently associated with respiratory illness. However, it has also been implicated in a polio-like neurological disorder, acute flaccid myelitis. Although sialic acid has been implicated in EV-D68 entry, the existence of a protein receptor has yet to be clarified. Here we identify neuron-specific intercellular adhesion molecule 5 (ICAM-5/telencephalin) as a cellular receptor for sialic acid-dependent and -independent EV-D68 viruses...

We report 59 cases of severe paediatric conditions linked with enterovirus (EV)-A71 and EV-D68 in France between May and October 2016. Fifty-two children had severe neurological symptoms. EV sequence-based typing for 42 cases revealed EV-A71 in 21 (18 subgenotype C1, detected for the first time in France) and EV-D68 in eight. Clinicians should be encouraged to obtain stool and respiratory specimens from patients presenting with severe neurological disorders for EV detection and characterisation.

In recent years, there has been a significant increase in detection of Enterovirus D-68 (EV-D68) among patients with severe respiratory infections worldwide. EV-D68 is now recognized as a re-emerging pathogen; however, due to lack of a permissive animal model for EV-D68, a comprehensive understanding of the pathogenesis and immune response against EV-D68 has been hampered. Recently, it was shown that EV-D68 has a strong affinity for α2,6-linked sialic acids (SAs) and we have shown previously that α2,6-linked SAs are abundantly present in the respiratory tract of cotton rats (Sigmodon hispidus)...
