The Positive-strand RNA viruses section of Virology Journal invites submissions of research articles and reviews covering all aspects of positive-strand RNA virus biology. Basic research topics of interest include all facets of the viral life cycle from viral attachment and entry, viral RNA replication and translation, viral gene expression/regulation, viral protein processing, viral particle assembly and secretion. We welcome studies that investigate interactions between the virus and host that impact viral replication and the cellular response to infection. Other topics include but are not limited to viral pathogenesis, epidemiology, and viral immunology. We also welcome basic and translational studies on the development of novel model systems, antiviral drugs and vaccines.
