“…Our study documents the extension of the known distribution of FLAV throughout western North America (Fig. 3) ( [1,3,[17][18][19][20][21][22][23][24][25][26][27][28][29]; GenBank accession numbers KJ958896.1 and KF028673.1). This extension may reflect improved molecular diagnostics and increased arbovirus surveillance in certain regions.…”

Flanders virus (FLAV; family Rhabdoviridae) is a mosquito-borne hapavirus with no known pathology that is frequently isolated during arbovirus surveillance programs. Here, we document the presence of FLAV in Culex tarsalis mosquitoes and a Canada goose (Branta canadensis) collected in western North America, outside of the currently recognized range of FLAV. Until now, FLAV-like viruses detected in the western United States were assumed to be Hart Park virus (HPV, family Rhabdoviridae), a closely related congener. A re-examination of archived viral isolates revealed that FLAV was circulating in California as early as 1963. FLAV also was isolated in Nebraska, Colorado, South Dakota, North Dakota, and Saskatchewan, Canada. Phylogenetic analysis of the U1 pseudogene for 117 taxa and eight nuclear genes for 15 taxa demonstrated no distinct clustering between western FLAV isolates. Assuming the range of FLAV has been expanding west, these results indicate that FLAV likely spread west following multiple invasion events. However, it remains to be determined if the detection of FLAV in western North America is due to expansion or is a result of enhanced arbovirus surveillance or diagnostic techniques. Currently, the impact of FLAV infection remains unknown.

“…Virus transmission can occur by biting (Watts et al 1972) and transovarially (Watts et al 1973, Miller et al 1977. Despite intensive investigation, LAC virus has not been detected in Canada, but another member of the California encephalitis virus group, snowshoe hare virus (SSH), has been associated with human cases of encephalitis (Fauve1 et al 1980, Belloncik et al 1982 and is the most prevalent arbovirus in Québec Province (Belloncik et al 1982(Belloncik et al , 1983.

Three cell lines (A.t. GRIP-1, 2, and 3) were established from Aedes triseriatus (Say) embryonated eggs or neonate larvae and their morphology, growth, karyotype, and isozyme pattern were studied. The isozyme alleles observed in the 3 cell lines also were found in adults of the original mosquito colony. Each cell line differed in enzymatic, morphological, and karyotypical patterns. La Crosse encephalitis (LAC) and snowshoe hare (SSH) viruses, members of the California encephalitis virus group, were able to replicate in these 3 cell lines. Furthermore, these cell lines, especially A.t. GRIP-1, were more sensitive than the Aedes aegypti (L.) (ATC 10) cell line for detection of small amounts of delta-endotoxin of Bacillus thuringiensis serovar. israelensis (de Barjac).

“…Transovarial transmission was not studied in the above experiments, but McLean et al (1975aMcLean et al ( , 1977b separately isolated SSHV from Aedes mosquito larvae at endemic sites and indeed used an isolate in some of their adult mosquito infection experiments. SSHV was also isolated from adult Aedes implicatus Vockeroth raised from larvae collected in Saskatchewan province of Canada (McLintock et al 1976) and from adult Aedes communis collected as larvae in Quebec province of Canada (Belloncik et al 1982), suggesting natural, transovarial transmission. Schopen et al (1991) showed experimentally that both Aedes triseriatus Say and Culiseta inornata transmitted SSHV transovarially after oral infection.…”

“…Addressing criterion #3 first, snowshoe hare virus has been isolated from at least 17 species or species groups of mosquitoes, as well as from a Simulium spp. black fly and two species of ticks ( Dermacentor andersoni and Haemaphysalis leporispalustris ) ( LeDuc 1979 , Belloncik et al 1983 , McLean 1983 , Turell and LeDuc 1983 , Mokry et al 1984 , Grimstad 1988 , Anderson et al 2015 , and Evans and Peterson 2019 ). Isolations have come repeatedly and primarily from two different groups of mosquitoes with quite different life histories.…”

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 tier of states bordering Canada. Reports of SSHV in northern Europe and Asia are probably the closely related to CHATV, or the less closely related Tahyna virus. Vertebrate associations include snowshoe hares and ground squirrels, demonstrated by field isolation of virus from wild-caught animals, seroconversion of snowshoe hares, seroconversion of sentinel rabbits, isolation of virus from sentinel rabbits, and experimental infections demonstrating viremia. Isolations of virus from field populations of mosquitoes include primarily univoltine and boreal mosquitoes of the genus Aedes, Culiseta impatiens and Culiseta inornata; and, rarely, certain multivoltine floodwater Aedes species. Experimental transmission studies in mosquitoes show infection in and transmission by boreal Aedes and Culiseta inornata. Isolation of SSHV from larval Aedes on three occasions, and experimentation in Culiseta inornata, reveal transovarial transmission of the virus in mosquitoes. Serosurveys reveal exposure to SSHV in human and domestic animals, with rates of seropositivity commonly high in some settings in Alaska and Canada, but disease in humans or horses has rarely been reported, only in Canada.
