Preface

Medically important RNA viruses with families include: Togavirus, Bunyavirus, Flavivirus, Filovirus, Arenavirus, Rhabdovirus, Paramyxovirus, Orthomyxovirus, Coronavirus, Retrovirus, Picornavirus, Reovirus, and Calicivirus. Some RNA viruses contain double-stranded RNA (Family Reoviridae) and some viruses have a life cycle that uses reverse transcriptase. Viruses contain ribonucleic acid (RNA) as their genetic material. Particularly, several human diseases are caused by RNA viruses. The main objective of this book on RNA viruses was to understand the RNA virus i.e a seroprevalence study based on molecular epidemiology such as genotyping tools by IgM/IgG, ELISA, PCR, FRNT50 and phylogenetic analysis to further confirm the RNA viruses causing diseases in tropical and subtropical countries. However, pathogenesis mechanisms causing viral diseases among the flaviviruses family have not been clearly understood and also little is known about the host responses to RNA viral infection. This book will surely help with these information gaps and also provide research information to the policymaker or planner for further diagnosis, control and prevention in future outbreaks of RNA
