“…The bank vole (Myodes glareolus), a small rodent that is common in woodland habitats throughout much of Europe and northwest Asia, is an zoonotic hyper-reservoir [3]. Bank voles host disease-causing viruses such as Puumala hantavirus [4], flavivirus tick borne encephalitis virus [5], orthonairovirus Crimean-Congo hemorrhagic fever virus [6], cowpox virus [7], and picornavirus Ljungan virus [8]; moreover, bank voles harbor paramyxoviruses [9,10], alphacoronaviruses [11], polyomaviruses [12], herpesviruses [13,14], anelloviruses [15], and hepaciviruses [16]. As bank voles host a diverse and important viral community, this species is an ideal model in which to study the potential effects of environmental factors on virus community and population dynamics.…”
