The monkeypox virus is a zoonotic virus belonging to the genus Orthopoxvirus, which itself is a member of the family Poxviridae (also known as the poxvirus family). [9] Of note, the Orthopoxvirus genus includes the variola virus that prior to eradication via the advent of the smallpox vaccine, was the cause of the infectious human disease known as smallpox. [10]
Virus classification showing major ranks This is a list of genera of biological viruses. See also Comparison of computer viruses. This is an alphabetical list of genera of biological viruses. It includes all genera and subgenera of viruses listed by the International Committee on Taxonomy of Viruses (ICTV) 2022 release. [1]
Many viruses, bacteria, protozoa, fungi, helminths (parasitic worms), and prions are identified as a confirmed or potential pathogen. In the United States, a Centers for Disease Control and Prevention program, begun in 1995, identified over a hundred patients with life-threatening illnesses that were considered to be of an infectious cause but ...
Experts point to a virus as the most likely source of the next pandemic — and for good reason: Most modern pandemics have come from viruses, and there are plenty of types of viruses that could ...
Viral evolution is a subfield of evolutionary biology and virology that is specifically concerned with the evolution of viruses. [1] [2] Viruses have short generation times, and many—in particular RNA viruses—have relatively high mutation rates (on the order of one point mutation or more per genome per round of replication).
Life on our 4.5 billion year old planet emerged about 3.7 billion years ago, and for the next two billion years at least it got along perfectly fine as nothing more than single-celled organisms ...
The virus, which only infected humans, probably descended from the poxviruses of rodents. [5] Humans probably came into contact with these rodents, and some people became infected by the viruses they carried. When viruses cross this so-called "species barrier", their effects can be severe, [6] and humans may have had little natural resistance ...
