About this Research Topic
Emerging infectious diseases are diseases caused by previously unidentified pathogens, such as COVID-19 by SARS-CoV-2, or those caused by known pathogens but that resulted in outbreaks in over relatively short period of time, such as Zika, defined by National Institute of Allergy and Infectious Diseases (NIAID). Re-emerging infectious diseases are those that disappear or significantly decline for a period, but then reappear, such as influenza. A large proportion of emerging and re-emerging infectious diseases are caused by RNA viruses, due to their high mutation rates, recombinations and/or reassortments.
Early identification is one of the most important factors controlling pandemic or endemic diseases. Without such viral genomic information, it is hard to track the virus source, to study the circulation in hosts and to evaluate the outbreak risks. The current COVID-19 pandemic provides a valuable lesson in this respect. Thus, this Research Topic aims to provide a platform for the researchers to discuss and explore the evolution and genomic characterization of emerging and re-emerging RNA viruses.
This Research Topic will focus on the adaptation and genomic evolution of emerging and re-emerging viruses, including but not limited to both computational bioinformatic and in vivo/in vitro studies on: virus recombination detection, phylogenetic tree building, evolutionary rate estimation and so on. Identification of virus host, isolation location and date should be highlighted, as we can only accurately estimate the risk of outbreaks by including such information. This Research Topic will accept Original Research, Reviews, Mini Reviews and Case Reports discussing these theme on the following emerging and re-emerging viruses:
• Filovirus (Ebola, Marburg etc.)
• Hemorrhagic fever viruses (Lassa fever, Crimean–Congo hemorrhagic fever etc.),
• Coronavirus (SARS, MERS, SARS-CoV-2 etc.)
• Nipah virus
• West Nile virus
• Influenza virus
• Zika virus
• Chikungunya virus
This Research Topic aims to build on research collected in the Frontiers in Virology Article Collection titled ‘Highly mutable animal RNA viruses: adaptation and evolution’.
