Jamestown Canyon virus, also known as the California orthobunyavirus, causes encephalitis in humans. Different mosquito species carry the virus in the summertime. Aedes canadensis and other mosquito species are responsible for transmission. Here is a list of mosquito species known to carry the virus. They may be: Aedes provocans, Coquillettidia perturbans, Anopheles punctipennis, and P. infestans.
Aedes canadensis
Aedes canadensis is a mosquito that is widespread across North America. Its geographic range includes inland areas in Alaska and Canada, coastal New Brunswick, and northern central U.S. states. In the Jamestown Canyon, it has been found in wetlands and inland waters. Aedes canadensis can transmit diseases in humans and can be transmitted by mosquitoes.
The disease is spread by bitten mosquitoes of many species. In this area, the virus has been isolated from Aedes canadensis more than any other species. Other species tested positive for the virus have included Aedes cinereus, Aedes vexans, and Oc. sticticus. Several new records were made for North American solutions of this mosquito species.
The Jamestown Canyon virus (JCV) has a wide geographic range and occurs in many parts of temperate North America. Infection rates are closely linked to the abundance of Aedes mosquitoes. The disease has a high mortality rate and is most common during summer months. Vaccination is not advisable unless symptoms are severe. Infected mosquitoes are generally evenly distributed in Connecticut.
Aedes provocans
The Aedes provocans mosquito has been implicated in an outbreak of Jamestown Canyon virus. A two-year field study was conducted in southern Saratoga County, New York, during which 238,909 mosquitoes were processed and tested for JC virus. Of these, 17 isolates were positive for the virus. The study also included mosquitoes collected at two sites, the Jamestown Canyon and the nearby Hudson River Valley.
The virus was isolated in mosquitoes from five species, including Aedes provocans and snowmelt Aedes. This study also identified new virus isolates of Aedes taeniorhynchus, Psorophora ferox, and C. melanura. The results of this study indicate that this mosquito could serve as a reservoir for the Jamestown Canyon virus and is the primary vector.
Coquillettidia perturbans
The mosquito Aedes canadensis has been confirmed as a vector of the Jamestown Canyon virus. In the spring and summer, this mosquito species are found on aquatic vegetation and is a significant vector of the disease. The mosquito breeds abundantly in a variety of locations in Michigan and occasionally migrates long distances. The mosquito feeds primarily during dusk. Nevertheless, the mosquito Aedes vexans is not an efficient vector of the virus and could be involved in the disease if the population increases.
The Jamestown Canyon Virus (JCV) is a mosquito-borne disease caused by a species of Aedes albopictus, Culiseta Niger, and Anopheles Niger. The virus is carried by these mosquitoes and causes encephalitis in humans. The infection rate in humans is highly variable across Connecticut and varies by season.
Anopheles punctipennis
Aedes canadensis and Anopheles punctipennis are two mosquito species suspected of carrying the Jamestown Canyon Virus. Both were collected from four of eastern equine encephalitis virus in central New York and New Jersey, respectively. DNA analysis of blood meals of both species confirmed their presence. The infection was observed in mosquitoes collected from central New York and New Jersey between weeks 23 and 33 in 2018.
The Jamestown Canyon Virus (JCV) is a newly emerging disease. The first human infection of the virus was reported in rural southwest Michigan in 1980. Subsequent human infections have occurred in numerous states. While white-tailed deer are the most important amplifying host, other mosquitoes, including Anopheles punctipennis, are also suspected of transmitting the virus.
