Rodent\u2010borne Ljungan virus (LV) is considered potentially zoonotic possibly causing neurological symptoms. Our objective was to understand the role of these two viruses compared to other pathogens in causing neurological infections in Finnish patients. Routine screening data were available for 400 patients aged 5\u201050 years, collected from December 2013 to December 2014 with suspected neurological infection. Depending on symptoms, patients were variously tested for herpesviruses, enteroviruses, varicella zoster virus, and <jats:italic>Mycoplasma pneumoniae<\/jats:italic>, while those suspected of tick bite were further tested for <jats:italic>Borrelia<\/jats:italic> spp. and tick\u2010borne encephalitis virus using antibody and\/or nucleic acid tests. For 380 patients, we also screened the RNA and antibody prevalence of LCMV and LV in order to test if either of these viruses were the causative agent. Data collected indicated that the causative microbial agent was confirmed in only 15.5% of all Finnish patients with neurological symptoms, with <jats:italic>M. pneumoniae<\/jats:italic> (26 cases) being the most common causative agent found in sera, whereas <jats:italic>Borrelia<\/jats:italic> spp. (15), herpes simplex viruses (7), and enteroviruses (5) were the most common agents confirmed in the CSF. The seroprevalences for LV and LCMV were 33.8% and 5.0%, respectively, but no samples were PCR\u2010positive. In this study, <jats:italic>M. pneumoniae<\/jats:italic> and <jats:italic>Borrelia<\/jats:italic> spp. were the most common causative agents of neurological infections in Finland. No LCMV or LV infections were detected. We conclude there was no association of LV with neurological diseases in this patient cohort.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jmv.24966","type":"journal-article","created":{"date-parts":[[2017,10,4]],"date-time":"2017-10-04T15:02:38Z","timestamp":1507129358000},"page":"429-435","source":"Crossref","is-referenced-by-count":16,"title":["Seroprevalence of lymphocytic choriomeningitis virus and Ljungan virus in Finnish patients with suspected neurological infections"],"prefix":"10.1002","volume":"90","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3642-8928","authenticated-orcid":false,"given":"Cristina","family":"Fevola","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Department of Virology University of Helsinki Helsinki Finland"},{"name":"Department of Biodiversity and Molecular Ecology, Research and Innovation Centre Fondazione Edmund Mach San Michele all'Adige (TN) Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suvi","family":"Kuivanen","sequence":"additional","affiliation":[{"name":"Department of Virology and Immunology University of Helsinki and Helsinki University Hospital Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teemu","family":"Smura","sequence":"additional","affiliation":[{"name":"Department of Virology and Immunology University of Helsinki and Helsinki University Hospital Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antti","family":"Vaheri","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Virology University of Helsinki Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannimari","family":"Kallio\u2010Kokko","sequence":"additional","affiliation":[{"name":"Department of Virology and Immunology University of Helsinki and Helsinki University Hospital Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heidi C.","family":"Hauffe","sequence":"additional","affiliation":[{"name":"Department of Biodiversity and Molecular Ecology, Research and Innovation Centre Fondazione Edmund Mach San Michele all'Adige (TN) Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olli","family":"Vapalahti","sequence":"additional","affiliation":[{"name":"Department of Virology and Immunology University of Helsinki and Helsinki University Hospital Helsinki Finland"},{"name":"Department of Veterinary Biosciences University of Helsinki Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annemarjut J.","family":"J\u00e4\u00e4skel\u00e4inen","sequence":"additional","affiliation":[{"name":"Department of Virology and Immunology University of Helsinki and Helsinki University Hospital Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,11,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI119002"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid1601.081467"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v3.i5.430"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.2741\/3200"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(03)00774-6"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMp068021"},{"key":"e_1_2_8_8_1","volume-title":"Handbook of Clinical Neurology","author":"Wilson MR","year":"2014"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1991.44.117"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid1507.01524"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1089\/vbz.2013.1526"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.10389"},{"key":"e_1_2_8_13_1","first-page":"4529","article-title":"Lymphocytic choriomeningitis infection of the central nervous system","volume":"13","author":"Kang S","year":"2008","journal-title":"J Infect Dis"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.105.3.e35"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid1602.091347"},{"key":"e_1_2_8_16_1","first-page":"249","article-title":"Notes from the field: a cluster of lymphocytic choriomeningitis virus infections transmitted through organ transplantation\u2010Iowa, 2013","volume":"63","author":"Schafer IJ","year":"2014","journal-title":"MMWR.
