Purpose: Recently, cases of serious illness in newborns infected with Echovirus 11 have been reported in Europe, including Italy. Here, we report the case of a newborn diagnosed with disseminated Echovirus 11 infection, which occurred in October 2023 in the Province of Bolzano, Italy.
Methods: A molecular screening, by Real-Time RT-PCR, was employed to analyse the cerebrospinal fluid, blood and stool samples, and nasal swabs. The entire viral genome was sequenced using both Illumina and Nanopore technologies.
Results: The patient was admitted to hospital due to fever. Molecular testing revealed the presence of enterovirus RNA. Typing confirmed the presence of Echovirus 11. The patient was initially treated with antibiotic therapy and, following the diagnosis of enterovirus infection, also with human immunoglobulins. Over the following days, the patient remained afebrile, with decreasing inflammation indices and in excellent general condition. Genomic and phylogenetic characterization suggested that the strain was similar to strains from severe cases reported in Europe.
Conclusions: Despite the low overall risk for the neonatal population in Europe, recent cases of Echovirus 11 have highlighted the importance of surveillance and complete genome sequencing is fundamental to understanding the phylogenetic relationships of Echovirus 11 variants.

Increasing evidence has shown that extracellular vesicles or exosomes released from virus-infected cells contain viral particles, genomes, or other pathogenic factors that move to neighbor cells, contributing to virus dissemination and productive infection. Our recent study demonstrated that exosomes carrying CVB3 virions exhibited greater infection efficiency than free virions because they accessed various entry routes, overcoming restrictions to viral tropism. However, the pathogenicity of exosomes carried CVB3 and their effect on immunological properties have not yet been completely explained.

Article Synopsis
- * Coxsackievirus B and various echoviruses are the most frequently identified culprits behind these infections, which often require supportive care as the initial treatment approach.
- * Clinical trials exploring therapies such as intravenous immunoglobulin and pleconaril have shown promise, but more research is necessary to fully understand their effectiveness and safety in treating neonatal EV hepatitis.
TBK1 and GABARAP family members suppress Coxsackievirus B infection by limiting viral production and promoting autophagic degradation of viral extracellular vesicles.

Host-pathogen dynamics are constantly at play during enteroviral infection. Coxsackievirus B (CVB) is a common juvenile enterovirus that infects multiple organs and drives inflammatory diseases including acute pancreatitis and myocarditis. Much like other enteroviruses, CVB is capable of manipulating host machinery to hijack and subvert autophagy for its benefit.

Enteroviruses are among the most common viral infectious agents of humans and cause a broad spectrum of mild-to-severe illness. Enteroviruses are transmitted primarily by the fecal-oral route, but the events associated with their intestinal replication are poorly defined. Here, we developed a neonatal mouse model of enterovirus infection by the enteral route using echovirus 5 and used this model to define the differential roles of type I and III interferons (IFNs) in enterovirus replication in the intestinal epithelium and subsequent dissemination to secondary tissues.
