California encephalitis virus causes encephalitis in humans. Mosquitos serve as its vectors. For this reason this virus is known as an arbovirus (arthropod-borne virus).
California encephalitis virus belongs to the Bunyaviridae family of viruses, and the genus Bunyavirus. It was first discovered in 1943 in the California Central Valley region of the United States and is a rare cause of disease in the Western World.
Initial infection by the virus and primary viremia causes the onset of non-specific symptoms such as headache and fever. Secondary viremia and the multiplication of the virus in the CNS causes symptoms such as stiff neck, lethargy and seizures. It can also cause encephalitis, when inflammation of the brain produced by infection of the virus damages nerve cells, which affects signalling of the brain to the body.
The virus particle is enveloped and contains three nucleocapsids. The envelope conatins G1 glycoproteins and neutralising antibodies against these proteins block fusion of the virus with host cells and inhibit haemagglutination. The virus gemone is over 12000 nucleotides in length and consists of three segments of various sized single-stranded RNA (negative sense and ambi-sense).
CEV is closely related to La Crosse Virus.

Virus classification involves naming and placing viruses into a taxonomic system. Like the relatively consistent classification systems seen for cellular organisms, virus classification is the subject of ongoing debate and proposals.

In epidemiology, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another.

A nucleotide is a chemical compound that consists of 3 portions: a heterocyclic base, a sugar, and one or more phosphate groups. In the most common nucleotides the base is a derivative of purine or pyrimidine, and the sugar is the pentose (five-carbon sugar) deoxyribose or ribose.
