California encephalitis serogroup viruses
The California encephalitis serogroup viruses, including California encephalitis virus, La Crosse virus, and Jamestown Canyon virus, belong to theBunyaviridaefamily. These viruses are transmitted and maintained byAedesmosquitoes and occur in the Rocky Mountains, eastern United States, southeast Canada, and western Europe. California encephalitis serogroup viruses cause symptoms (eg, fever, somnolence, obtundation, focal neurologic findings, seizures) primarily in children except for Jamestown Canyon virus, which may also affect adults. Temporal lobe involvement may mimic herpes encephalitis; 20% of patients develop behavioral problems or recurrent seizures. No treatment is available.
