Abstract In 2018, the family Arenaviridae was expanded by inclusion of 1 new genus and 5 novel species. At the same time, the recently established order Bunyavirales was expanded by 3 species. This article presents the updated taxonomy of the family Arenaviridae and the order Bunyavirales as now accepted by the International Committee on Taxonomy of Viruses (ICTV) and summarizes additional taxonomic proposals that may afect the order in the near future.

    viruses Review Phleboviruses and the Type I Interferon Response Jennifer Deborah Wuerth and Friedemann Weber * Institute for Virology, FB10-Veterinary Medicine, Justus-Liebig University, Giessen 35392, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-641-99-383-50 Academic Editors: Jane Tao and Pierre-Yves Lozach Received: 8 May 2016; Accepted: 20 June 2016; Published: 22 June 2016 Abstract: The genus Phlebovirus of the family Bunyaviridae contains a number of emerging virus species which pose a threat to both human and animal health. Most prominent members include Rift Valley fever virus (RVFV), sandfly fever Naples virus (SFNV), sandfly fever Sicilian virus (SFSV), Toscana virus (TOSV), Punta Toro virus (PTV), and the two new members severe fever with thrombocytopenia syndrome virus (SFTSV) and Heartland virus (HRTV). The nonstructural protein NSs is well established as the main phleboviral virulence factor in the mammalian host. NSs acts as antagonist of the antiviral type I interferon (IFN) system. Recent progress in the elucidation of the molecular functions of a growing list of NSs proteins highlights the astonishing variety of strategies employed by phleboviruses to evade the IFN system. Keywords: phlebovirus; NSs protein; interferon; RIG-I; PKR 1. Introduction The family Bunyaviridae contains five genera, among which the Orthobunyavirus, Phlebovirus, Nairovirus, and Hantavirus all contain species that are pathogenic to humans and animals, while the genus Tospovirus contains

  • Chapter 11. Phlebotomus Fever—Sandfly Fever
    Chapter 11 Phlebotomus Fever—Sandfly Fever Koray Ergunay Hacettepe University Faculty of Medicine, Department of Medical Microbiology, Virology Unit, Ankara, Turkey CASE PRESENTATION During mid-August, a 27-year-old male was admitted to the emergency ward with high fever, chills, severe headache, joint pain, watery diarrhea, nausea and, vomiting, which had started the day before. The initial complete physical examination demonstrated a fever of 38.9C, generalized muscle tenderness, and multiple skin lesions suggesting insect bites on the upper left limb. Neurological examination was normal without meningeal signs. Medical his- tory revealed no previous disease of significance but an exposure to mosqui- toes during his stay at his cousin’s cottage 5 days ago. He had vomited three times during the last 24 hours. No apparent risk for infectious gastroenteritis could be identified. Laboratory evaluation demonstrated decreased leukocyte count (3.8 3 103/μL) with relative lymphocytosis, decreased platelet count (1.32 3 105/μL), elevated alanine aminotransferase (ALT, 101 U/L), aspartate aminotransferase (AST, 128 U/L), gamma glutamyl transpeptidase (GGT, 107 U/L), creatinine phosphokinase (CPK, 428 U/L), and lactate dehydroge- nase (LDH, 354 U/L) levels. Hemoglobulin, C-reactive protein, total protein, blood urea nitrogen (BUN), albumin, creatinine, prothrombin time (PT), acti- vated partial thromboplastin time (aPTT), international normalized ratio (INR), and the chest X-ray were within normal limits. The patient was trans- ferred to the infectious diseases department with the preliminary diagnosis of undifferentiated viral febrile condition, and blood and stool samples were sub- mitted for microbiological analyses. Symptomatic treatment with intravenous rehydration and anti-pyretics was initiated.

  • Hantavirus Disease Were HPS Is More Common in Late Spring and Early Summer in Seropositive in One Study in the U.K
    Hantavirus Importance Hantaviruses are a large group of viruses that circulate asymptomatically in Disease rodents, insectivores and bats, but sometimes cause illnesses in humans. Some of these agents can occur in laboratory rodents or pet rats. Clinical cases in humans vary in Hantavirus Fever, severity: some hantaviruses tend to cause mild disease, typically with complete recovery; others frequently cause serious illnesses with case fatality rates of 30% or Hemorrhagic Fever with Renal higher. Hantavirus infections in people are fairly common in parts of Asia, Europe and Syndrome (HFRS), Nephropathia South America, but they seem to be less frequent in North America. Hantaviruses may Epidemica (NE), Hantavirus occasionally infect animals other than their usual hosts; however, there is currently no Pulmonary Syndrome (HPS), evidence that they cause any illnesses in these animals, with the possible exception of Hantavirus Cardiopulmonary nonhuman primates. Syndrome, Hemorrhagic Nephrosonephritis, Epidemic Etiology Hemorrhagic Fever, Korean Hantaviruses are members of the genus Orthohantavirus in the family Hantaviridae Hemorrhagic Fever and order Bunyavirales. As of 2017, 41 species of hantaviruses had officially accepted names, but there is ongoing debate about which viruses should be considered discrete species, and additional viruses have been discovered but not yet classified. Different Last Updated: September 2018 viruses tend to be associated with the two major clinical syndromes in humans, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary (or cardiopulmonary) syndrome (HPS). However, this distinction is not absolute: viruses that are usually associated with HFRS have been infrequently linked to HPS and vice versa. A mild form of HFRS in Europe is commonly called nephropathia epidemica.
