Michigan state health officials, along with the Ottawa County Health Department have confirmed the first human Jamestown Canyon virus (JCV) case of the year in the state.
Jamestown Canyon virus (JCV) is a mosquito-borne pathogen that circulates widely in North America, primarily between deer and a variety of mosquito species, but can also infect humans. Since 2000, more than 50 human cases of JCV have been identified nationally.
Most infections caused by Jamestown Canyon Virus are either asymptomatic or result in a mild febrile illness, but more serious central nervous system complications, including meningitis and encephalitis, can also occur. There is no specific treatment for JCV, and care is supportive until symptoms resolve.
“During the warm weather months in Michigan, there is always a risk of viruses spread by mosquitoes, including but not limited to West Nile virus and Eastern Equine Encephalitis.” said Dr. Joneigh Khaldun, MDHHS chief medical executive and chief deputy director for health. “This is an important reminder to stay vigilant and protect against mosquito bites throughout the summer and into the fall”.
Michigan reported its first two cases of Jamestown Canyon virus in 2018 in patients from Oakland and Menominee counties. In 2019, one case was detected in a person from Cass County.
Residents can stay healthy by using simple, effective strategies to protect themselves and their families. The following steps are recommended to avoid Jamestown Canyon virus and other mosquito-borne diseases:
- Apply insect repellents that contain the active ingredient DEET, or other EPA-approved products to exposed skin or clothing. Always follow the manufacturer’s directions for use.
- Wear light-colored, long-sleeved shirts and long pants when outdoors. Apply insect repellent to clothing to help prevent bites.
- Maintain window and door screening to help keep mosquitoes outside.
- Empty water from mosquito breeding sites around the home, such as buckets, unused kiddie pools, old tires or similar sites where mosquitoes lay eggs.
