Insights

Enterovirus D68 (EV-D68), a Picornaviridae family virus, causes respiratory illness and neurological diseases like acute flaccid myelitis (AFM). This review details EV-D68 knowledge and its link to AFM development.

Area of Science:

  • Virology
  • Neurology
  • Infectious Diseases

Background:

  • Enterovirus D68 (EV-D68) is a significant member of the Picornaviridae family, first isolated in 1962.
  • EV-D68 is associated with widespread respiratory illness outbreaks in children and has been increasingly linked to neurological conditions, notably acute flaccid myelitis (AFM).
  • Recent data indicates a rise in EV-D68 associated AFM cases, particularly in Europe.

Purpose of the Study:

  • To review current knowledge on Enterovirus D68 (EV-D68).
  • To explore the association between EV-D68 and the development of acute flaccid myelitis (AFM).

Main Methods:

  • Review of existing literature on EV-D68.
  • Discussion of diagnostic methods including quantitative PCR and pan-EV PCR with sequencing.
  • Evaluation of serological test limitations due to antigen cross-reactivity.

Main Results:

  • EV-D68 diagnosis primarily relies on molecular methods like quantitative PCR.
  • Serological tests for EV-D68 are constrained by cross-reactivity issues.
  • Antiviral drug evaluations for EV-D68 have yielded promising outcomes.

Conclusions:

  • EV-D68 poses a significant threat, causing both respiratory and neurological diseases.
  • Further research into EV-D68 pathogenesis and effective treatments is warranted.
  • Understanding the EV-D68-AFM link is crucial for public health interventions.
