Welcome to the calicivirus family web page! My name is Melissa Valadez, and I am a junior majoring in human biology at Stanford University. My partner in crime is Elizabeth Salas, also a junior majoring in human biology at Stanford University. We made this web page for a class, Humans & Viruses, taught by Dr. Robert Siegel. Our classmates and we are making web pages for the human virus families and for important antiviral drugs, as a resource for anyone looking for information on viruses.
Caliciviridae are positive, ssRNA viruses. The genome is linear and monopartite. The capsid is a non-enveloped, icosahedral. Most caliciviruses range from 30-39nm in diameter. Calicivirus are named for the typical 32 "cupped" shapped depressions found in typical caliciviruses. There have been some recent changes in the classification of caliciviruses. Two new genera have been formed, informally known as "Norwalk-like viruses" and "Sapporo-like viruses." Read on through the website to find out more about these changes.
Caliciviruses are a family of viruses associated with gastroenteritis. These viruses are highly infectious and are transmitted through the fecal-oral route. Symptoms include nausea, vomiting, diarrhea and abdominal cramps. Beware of the dirty "calyx." It could be carrying a calicivirus!
