Background: Rhino-enteroviruses, particularly enterovirus strain D68 (EV-D68), have been associated with severe respiratory distress in children. The goal of this study was to compare the long-term outcomes of children with EV-D68 infection to that of children with other enterovirus / rhinovirus.
Methods: Nasopharyngeal swabs from 174 children presenting with respiratory distress were tested by PCR for respiratory viruses. The primary outcome was diagnosis of a chronic respiratory condition within the follow-up period. Admission to intensive care, and length of stay were recorded. Odds ratios were determined using multinomial logistic regression.
Results: During 5 years of follow-up, the crude odds of diagnosis with a chronic respiratory condition were significantly more likely in EV-D68 cases (OR: 1.95, 95% CI: 1.02, 3.82), but failed to remain significant after adjusting for a past history of asthma. Upon admission for a primary concern of asthma, length of stay both in hospital and intensive care were significantly longer in EV-D68 cases (OR: 2.10 [95% CI: 1.56, 2.82, < 0.001]) and (OR: 5.18 [95% CI: 1.90, 6.28, < 0.001]), respectively. After adjustment for a history of asthma, EV-D68 cases had significantly longer length of stay in hospital, admitted for 1.94 days for each day that controls were admitted (95% CI: 1.40, 2.68). In admissions to intensive care, EV-D68 cases spent 2.74 days for each day of admission in controls (95% CI: 1.62, 4.97, < 0.001).
Conclusions: Ours is first study to assess prognostic respiratory outcomes of patients infected with EV-D68 in childhood. Our study finds that EV-D68 cases were significantly more likely be hospitalized for longer than other enterovirus/rhinovirus controls in subsequent admissions for respiratory distress. Need for intensive care was significantly longer in EV-D68 infections. Our next steps will be validation in a larger sample size.

Rhinoviruses and respiratory enteroviruses remain among the leading causes of acute respiratory infections, particularly in children. Little is known about the genetic diversity of enteroviruses and rhinoviruses in pediatric patients with acute respiratory infections in Russia. We assessed the prevalence of human rhinoviruses/enteroviruses (HRV/EV) in 1992 children aged 0 to 17 years hospitalized with acute respiratory infections during the 2023-2024 epidemic season using PCR.

Enteroviruses (EVs) are a highly diverse group of viruses multiplying primarily in the gastrointestinal tract and/or the upper respiratory tract, initially distributed in two separate genera: Enterovirus and Rhinovirus, respectively. According to the similarities in genome organization and particle structure, rhinovirus species were later reclassified as also belonging to genus Enterovirus. Human EV infections are usually asymptomatic or causing mild clinical manifestations.

Enterovirus-D68 (EV-D68) is a plus-strand RNA virus that primarily causes infant respiratory infections. In rare pediatric cases, infection with EV-D68 has been associated with acute flaccid myelitis, a polio-like paralytic disease. We have previously demonstrated that EV-D68 induces nonselective autophagy for its benefit.

Aim: We report the epidemiology, treatment and outcomes of acute flaccid myelitis (AFM), including the first two cases of enterovirus (EV) D68 myelitis, in Singapore.
Methods: Retrospective observational study from a paediatric hospital in Singapore, from January 2012 to December 2022. Clinical, laboratory, neuroimaging and outcome data were analysed.

Enterovirus D68 (EV-D68) has had several outbreaks worldwide, yet no FDA-approved antiviral is available for treating this viral infection. EV-D68 infection typically leads to respiratory illnesses and, in severe cases, can cause neurological complications and even death, particularly in children. This study identified a small molecule, A-967079, as an EV-D68 antiviral through phenotypical screening.
