Snowshoe Hare Virus Symptoms

Snowshoe hare virus infection (SSHV) is a neglected mosquito-borne illness that can cause neuroinvasive disease in humans. SSHV was first detected in the blood of a snowshoe hare in 1959 found in the US state of Montana, [1] and has since been classified as one of the 18 California serogroup (CSG) viruses. [2].

Snowshoe Hare Virus Agent Information Sheet Boston University Research Occupational Health Program (ROHP) 617-358-7647 Agent Snowshoe Hare virus is a member of the California encephalitis subgroup of Bunyviridae. It was first identified in Montana in 1958. Its distribution includes Canada, Alaska, and Eastern Asia.

Disease/Infection Snowshoe Hare virus symptoms can include flu like illness. Snowshoe hare virus (SSHV), within the California serogroup of the genus Orthobunyavirus, family Peribunyaviridae, was first isolated from a snowshoe hare (Lepus americanus) in Montana, United States, in 1959. The virus, closely related to LaCrosse.

Human cases of CSG virus infection were initially reported in the same area, followed by sporadic cases across the US and Canada. In 2024, BC identified the first occurrence of a small cluster of snowshoe hare virus encephalitis cases in the Sea to Sky corridor, prompting renewed attention to the virus. Epidemiology: Jamestown Canyon virus (JCV) and Snowshoe Hare Virus (SSHV) are mosquito-borne viruses that belong to the California serogroup in the Bunyaviridae family.

They have a similar life cycle and clinical presentation to West Nile Virus. and circulate between mosquitoes and mammalian reservoirs. When symptoms occur, it is usually 5-15 days after a mosquito bite.

JCV/SSHV have been. California serogroup (CSG) viruses include many viruses, such as the Jamestown Canyon and Snowshoe hare viruses, which are the most common in Québec. These viruses are also found throughout Canada and the United States.

They are spread through the bite of an infected mosquito. Snowshoe hare virus (SSHV) is a zoonotic arthropod-borne virus (arbovirus) circulating in colder areas of the Northern Hemisphere. It is one of the california serogroup viruses of the Orthobunyavirus genus in the Peribunyaviridae family.

SSHV is maintained in an enzootic cycle between small mammals and mosquitoes, assumably of the genera Aedes and Culiseta. SSHV has been frequently isolated. Snowshoe Hare Virus A.

Classification and description: Family, Bunyaviridae; genus, Bunyavirus; species, Snowshoe hare virus. A member of the California group of viruses. Causes an illness, usually in young children, characterized by fever, severe headache, and nausea (3).

B. Abstract Snowshoe hare virus (SSHV), within the California serogroup of the genus Orthobunyavirus, family Peribunyaviridae, was first isolated from a snowshoe hare (Lepus americanus) in Montana, United States, in 1959. The virus, closely related to LaCrosse virus (LACV) and Chatanga virus (CHATV), occurs across Canada and the northern latitudes of the United States, primarily in the northern.
