Jamestown Canyon Virus Statistics
- In 2015, two cases of Jamestown Canyon virus, a California group virus related to La Crosse, were reported in Minnesota. Patients were aged 56 to 77 and illnesses ranged from fever to more severe illness, including meningoencephalitis.
- Cases of Jamestown Canyon virus occur throughout the United States but are only reported sporadically. The Centers for Disease Control and Prevention (CDC) began reporting for JCV in 2004 and has since received a few reports of JCV cases each year. Under-diagnosis and under-reporting of disease are likely as diagnostic testing for JCV is not widely available.
- Human disease cases occur during warmer months when mosquitoes are active, most commonly between May and September.
