The Positive-strand RNA
viruses section of
Virology Journal invites 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.An RNA
virus is a
virus that has RNA (ribonucleic acid) as its genetic material.This nucleic acid is usually single-stranded RNA (ssRNA) but may be double-stranded RNA (dsRNA). Notable
human diseases caused by RNA
viruses include the common cold, influenza, SARS, COVID-19,
hepatitis C,
hepatitis E, West Nile fever, Ebola
virus disease, rabies, polio and measles.The International Committee on Taxonomy of
Viruses (ICTV) classifies RNA
viruses as those that belong to Group III, Group IV or Group V of the Baltimore classification system of classifying
viruses and does not consider
viruses with DNA intermediates in their life cycle as RNA viruses.
Viruses with RNA as their genetic material which also include DNA intermediates in their
replication cycle are called retroviruses, and comprise Group VI of the Baltimore classification. Notable human retroviruses include HIV-1 and HIV-2, the cause of the disease AIDS.Another term for RNA
viruses that explicitly excludes retroviruses is ribovirus.RNA
viruses can be further classified according to the sense or polarity of their RNA into negative-sense and positive-sense, or ambisense RNA viruses. Positive-sense viral RNA is similar to mRNA and thus can be immediately translated by the host cell. Negative-sense viral RNA is complementary to mRNA and thus must be converted to positive-sense RNA by an RNA-dependent RNA polymerase before translation. Purified RNA of a positive-sense
virus can directly cause
infection though it may be less infectious than the whole
virus particle. In contrast, purified RNA of a negative-sense
virus is not infectious by itself as it needs to be transcribed into positive-sense RNA; each virion can be transcribed to several positive-sense RNAs. Ambisense RNA
viruses resemble negative-sense RNA viruses, except they also translate genes from the positive strand.The double-stranded (ds)RNA
viruses represent a diverse group of
viruses that vary widely in host range (humans, animals, plants, fungi, and bacteria),
genome segment number (one to twelve), and virion organization (Triangulation number, capsid layers, spikes, turrets, etc.). Members of this group include the rotaviruses, which are the most common cause of gastroenteritis in young children, and picobirnaviruses, which are the most common
virus in fecal samples of both humans and animals with or without signs of diarrhea. Bluetongue
virus is an economically important pathogen of cattle and sheep. In recent years, progress has been made in determining, at atomic and subnanometeric levels, the structures of a number of key viral proteins and of the virion capsids of several dsRNA viruses, highlighting the significant parallels in the structure and replicative processes of many of these viruses.Top
