The importance of infectious diseases originating from or carried by wildlife is increasingly being recognised. An understanding of these diseases is based on knowledge of their epidemiology; thus, it is essential to gather pathogen data which are region-specific. The objective of this review was to provide an update on changes in the epidemiology...
Article
Rabbit hemorrhagic disease (RHD) was detected in European rabbits ( Oryctolagus cuniculus) for the first time ever in Finland in 2016. Reports of dead feral rabbits in Helsinki started to accumulate from April 2016. The Finnish Food Safety Authority Evira received the first animals in late April, and the main necropsy finding was severe, acute necr...

At the end of World War II, tens of thousands of tons of chemical warfare agents – mostly mustard gas – were dumped in the Gotland Deep – a deep basin in the middle of the otherwise shallow Baltic Sea. Decades later, these weapons are being reactivated – both literally (perhaps on the faces of dead seals, and in fishermen’s nets) and also in our im...

Lagoviruses belong to the Caliciviridae family. They were first recognized as highly pathogenic viruses of the European rabbit (Oryctolagus cuniculus) and European brown hare (Lepus europaeus) that emerged in the 1970-1980s, namely, rabbit haemorrhagic disease virus (RHDV) and European brown hare syndrome virus (EBHSV), according to the host specie...
Article
Incursion of rabbit haemorrhagic disease virus (RHDV) into Sweden was documented in 1990 and it is now considered endemic in wild rabbit (Oryctolagus cuniculus) populations. Rabbit haemorrhagic disease virus 2 (RHDV2), a new, related lagovirus was first detected in France in 2010, and has spread rapidly throughout Europe and beyond. However, knowle...
