Tick-borne seabird viruses
Tick-borne seabird viruses have been the focus of much scientific attention. No less than fifty-three viruses have been isolated from Ixodes uriae (the seabird tick). These include members of the Kemerovo serogroup (Reoviridae: Orbivirus), the group B serogroup (Flaviviridae: Flavivirus), the Sakhalin and Hughes serogroups (Bunyaviridae: Nairovirus), and the Uukuniemi serogroup (Bunyaviridae: Uukuvirus).
Because of wide geographical ranges, and colonial breeding habits of seabirds, these viruses are able to proliferate with ease. Many of these viruses have been isolated from ticks sampled from British seabird colonies. Humans can also become infected. Most at risk are biologists, ornithologists, tourists, and egg-collectors that enter seabird colonies.
