A meningoencephalitis outbreak associated with echovirus type 18 (E18) in south-western Hungary in mid-2023
Echovirus type 18 (E18) is a member of the genus Enterovirus of the family Picornaviridae. In this study, we investigated the characteristics of E18 infections in hospitalized adults with meningoencephalitis that occurred during an unusual epidemic in south-western Hungary in mid-2023. Five (6.1%) out of 82 cerebrospinal fluid specimens that were tested were positive for an enterovirus, four of which were E18 (OR372160 and PP861087-PP861090). Headache (100%), fever (75%), retrobulbar pain (50%), nausea (50%), joint/limb pain (50%), exanthema, photophobia, and vomiting were the most common symptoms. Sequence analysis showed that these viruses were related to unpublished emerging E18 strains from France (2022/2023) and China (2019/2020). Further study is necessary to monitor the circulation of epidemic/pandemic E18 variants over time.
期刊介绍：
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
