Two cases of acute severe flaccid myelitis associated with enterovirus D68 infection in children, Norway, autumn The authors have not received any funding or benefits from industry or elsewhere to conduct this study. Most performed typing of EV-positive samples obtained from individuals with neurological infections, but only half of the countries included respiratory infections, HFMD, myocarditis, haemorrhagic conjunctivitis and post-mortem investigations in their laboratory-based EV surveillance. Reporting system for HFMD. Introduction A total of enterovirus EV types have been identified from humans, and of these, 45 have been discovered in the past 10 years [ 1 ]. We have mapped European laboratory capacity for identification and characterisation of non-polio EVs to improve preparedness to respond to re -emerging EVs linked to severe disease.
HH coordinated the data collection and analysis, as well as the drafting of the manuscript. Clusters of respiratory disease caused by EV-D68, a species D EV, occasionally leading to severe neurological complications, have previously been reported in Europe and North America [ 17 – 22 ]. Although more efficient molecular detection techniques have mostly replaced these slow and laborious cell culture methods in primary diagnostic laboratories, virus isolation still plays a crucial role in polio surveillance and all polio cases are confirmed by in vitro cell culture [ 24 – 26 ]. Seven-fold increase in viral meningo-encephalitis reports in England and Wales during Transmission patterns of human enterovirus 71 to, from and among European countries, to Hence, continued careful monitoring and vigilant testing of respiratory samples for EV-D68 and for other non-polio EVs are still needed. This should make it easier to introduce more uniform screening of EVs in clinical samples with well-defined sensitivities and specificities on a much greater scale.
For Belgium, reverse primer is outside the region shown.
Support Center Support Center. If the country was unable to provide an exact number, we used the upper limit of estimation for the calculations.
A broader understanding of comparability of different assays is also essential, especially in view of emerging viruses with public health importance. We also calculated the proportion of EV-positive samples typed perinhabitants for the countries that were essaj to provide these data.
Enterovirus D68 – Research Paper Example
A total of enterovirus EV types have been identified from humans, and of these, 45 have been discovered in the past 10 years [ 1 ]. Enteroviruses in human disease. Surveillance includes neurological infections.
Non-cultured EV-positive samples typed by sequence analysis. Unbiased metagenomic sequencing complements specific routine diagnostic methods and increases chances to detect rare viral strains.
The association of recombination enterovidus in the founding and emergence esaay subgenogroup evolutionary lineages of human enterovirus All authors contributed to the manuscript and approved the final version.
Sequences from all EV types have been used to create consensus sequences shown in the alignment. Direct identification of human enterovirus serotypes in cerebrospinal fluid by amplification and sequencing of the VP1 region. The questionnaire was divided into four parts. Detection of human enterovirus and human parechovirus HPeV genotypes from clinical stool samples: However, some of the newly identified EV types within species C e.
Enterovirus D68: a clinically important respiratory enterovirus.
Polioviruses, like most other EVs, are transmitted mostly via the faecal—oral route [ 5 ]. National laboratory capability for EV identification. Arch Pathol Lab Med. Participation in regular external quality control programmes helps laboratories to identify gaps in detection capabilities. You may share and adapt the material, but must give appropriate credit to the source, provide a link to the licence, and indicate if changes were made.
All except one country performed virus isolation at the national level, and 10 countries also performed it at the local level.
Enterovirus D a clinically important respiratory enterovirus.
Limitations As the surveillance and detection systems applied may change from time to time, it is important to note that this study reflects the situation in individual countries as described in and As we identified a few potential mismatches with primers in terms of EV-D68 and EV-C detection, it is important to consider that not all previously published primers or commercial assays can detect all EV types.
HH administered the questionnaire with the support of EB. Genome characterisation of enteroviruses and The National Coordinators were asked to assign a person or persons from their country to fill in the survey from the national perspective.
EVs cause a wide spectrum of infections in humans, including non-specific febrile illness and viral exanthema, respiratory infections, hand, foot and mouth disease HFMDmyocarditis, meningitis, encephalitis and, rarely, acute flaccid paralysis AFP [ 5 ].
As the surveillance entrovirus detection systems applied may change from time to time, it is important to note that this study reflects the situation in individual countries as described in and The manuscript was sent to one or more of the above individuals from each country before submission enterlvirus they were asked to check the data presented accordingly.

Virology, epidemiology, pathogenesis, and control of enterovirus Although more efficient molecular detection techniques have mostly replaced these slow and laborious cell culture methods in primary diagnostic laboratories, virus isolation still plays a crucial role in polio surveillance and all polio cases are confirmed by in vitro cell culture [ 24 – 26 ]. National Center for Biotechnology V68U.
Based essag data, six countries typed over specimens mostly by sequencing, whereas 11 countries characterised under 50 EV-positive samples.
