California Viral Encephalitides (CVE) refers to a group of viral infections that cause inflammation in the brain, primarily affecting individuals in the state of California, United States. This term encompasses a set of encephalitides primarily caused by two distinct viruses: California serogroup viruses (CSV) and Jamestown Canyon virus (JCV).
CSV includes a family of viruses, such as La Crosse virus (LACV), Snowshoe hare virus (SSHV), and others, which are predominantly transmitted to humans through the bite of infected mosquitoes. These viruses are more common in rural and wooded areas where mosquitoes and the animals they feed on reside, infecting primarily children and young adults. Infection with CSV can lead to various symptoms, including fever, headache, nausea, vomiting, fatigue, altered mental state, seizures, and, in severe cases, coma or even death.
On the other hand, JCV is also transmitted through mosquito bites, primarily affecting individuals in California and neighboring regions. It is responsible for causing similar symptoms as CSV, including fever, headache, muscle pain, and fatigue. In rare cases, severe infection can lead to inflammation of the brain and spinal cord, resulting in encephalitis.
California Viral Encephalitides highlight the distinct infections caused by CSV and JCV, which are prevalent in California and nearby areas. Proper preventive measures, such as mosquito control and personal protective measures against mosquito bites, are crucial for reducing the risk of infection and potential complications associated with these viral encephalitides.
