“…Historically, reindeer were herded by residents of six of the 18 villages surveyed in our study: Wainwright, Noatak, Buckland, Savoonga, Aniak, and Tanana (Finstad G, unpublished data). Inkoo virus is endemic in Siberia 13 and we hypothesize that this virus could have been introduced into Alaska in viremic reindeer more than 100 years ago. Two moose in our study circulated antibodies to both JC and INK viruses, and the presence of moose in villages was statistically associated with antibodies to JC virus in humans; this suggests a possible role for moose in the amplification of this virus in Alaska.…”

“…This ethnic-linguistic group has traditional social and cultural ties to Siberian Eskimos on the Chukchi Peninsula (Russia) where TAH virus circulates. 13 Contact between the two groups occurred until the start of the Cold War (1948). All three viruses, if present in Alaska before 1984, did not appear to be of public health importance in the villages surveyed.…”

[13][14][15] Human serosurveys done in forest and tundra landscapes have shown a high prevalence of neutralizing antibodies to TAH virus (27-46%) and a prevalence of 7% to GET virus. 13,14 Two to 6% of humans circulated antibodies to BAT virus.…”

Ťahyňa virus (TAHV) is an orthobunyavirus and was the first arbovirus isolated from mosquitoes in Europe and is associated with floodplain areas as a characteristic biotope, hares as reservoir hosts and the mammal‐feeding mosquitoes Aedes vexans as the main vector. The disease caused by TAHV (“Valtice fever”) was detected in people with acute flu‐like illness in the 1960s, and later the medical significance of TAHV became the subject of many studies. Although TAHV infections are widespread, the prevalence and number of actual cases, clinical manifestations in humans and animals and the ecology of transmission by mosquitoes and their vertebrate hosts are rarely reported. Despite its association with meningitis in humans, TAHV is a neglected human pathogen with unknown public health importance in Central Europe, and a potential emerging disease threat elsewhere in Europe due to extreme summer flooding events.

BackgroundInkoo virus (INKV) is a less known mosquito-borne virus belonging to Bunyaviridae, genus Orthobunyavirus, California serogroup. Studies indicate that INKV infection is mainly asymptomatic, but can cause mild encephalitis in humans. In northern Europe, the sero-prevalence against INKV is high, 41% in Sweden and 51% in Finland. Previously, INKV RNA has been detected in adult Aedes (Ae.) communis, Ae. hexodontus and Ae. punctor mosquitoes and Ae. communis larvae, but there are still gaps of knowledge regarding mosquito vectors and genetic diversity. Therefore, we aimed to determine the occurrence of INKV in its mosquito vector and characterize the isolates.MethodsAbout 125,000 mosquitoes were collected during a mosquito-borne virus surveillance in northern Sweden during the summer period of 2015. Of these, 10,000 mosquitoes were processed for virus isolation and detection using cell culture and RT-PCR. Virus isolates were further characterized by whole genome sequencing. Genetic typing of mosquito species was conducted by cytochrome oxidase subunit I (COI) gene amplification and sequencing (genetic barcoding).ResultsSeveral Ae. communis mosquitoes were found positive for INKV RNA and two isolates were obtained. The first complete sequences of the small (S), medium (M), and large (L) segments of INKV in Sweden were obtained. Phylogenetic analysis showed that the INKV genome was most closely related to other INKV isolates from Sweden and Finland. Of the three INKV genome segments, the INKV M segment had the highest frequency of non-synonymous mutations. The overall G/C-content of INKV genes was low for the N/NSs genes (43.8–45.5%), polyprotein (Gn/Gc/NSm) gene (35.6%) and the RNA polymerase gene (33.8%) This may be due to the fact that INKV in most instances utilized A or T in the third codon position.ConclusionsINKV is frequently circulating in northern Sweden and Ae. communis is the key vector. The high mutation rate of the INKV M segment may have consequences on virulenceElectronic supplementary materialThe online version of this article (doi:10.1186/s12985-017-0725-5) contains supplementary material, which is available to authorized users.
