UK squirrelpox virus is an entirely different virus to that which causes skin fibromas (tumours) in American grey squirrels. UK grey squirrels carry the virus but are unaffected by it whereas in red squirrels, the virus causes skin ulcers, lesions, and scabs. It can also cause swelling and discharge (from the lesions/scabs) near the eyes, mouth ...
Grey squirrels do not die from the squirrelpox virus and can infect red squirrels causing the appearance of scabs and lesions on the face, feet, and genitals and eventually death. [6] In Great Britain , grey squirrels have been able to spread 17 to 25 times faster through competitive exclusion of the red squirrel due to increased mortality of ...

[10] The European crayfish is susceptible to crayfish plague which is spread by the introduced signal crayfish. [11] Unlike some other environmental problems such as pollution, the effect of an introduced species is not a single event.

The name of the family, Poxviridae, is a legacy of the original grouping of viruses associated with diseases that produced poxes on the skin.Modern viral classification is based on phenotypic characteristics; morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
