The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Some 2,000 animals have been expected to be killed after a worker in a pet shop tested positive for the virus, which was also found among the pets.

Larger than red squirrels and capable of storing up to four times more fat, gray squirrels are better able to survive winter conditions. They produce more young and can live at higher densities. Gray squirrels also carry the squirrelpox virus, to which red squirrels have no immunity. When an infected gray squirrel introduces squirrelpox to a ...
Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] They alternate between torpor bouts of 7 to 10 days when their body temperatures drops to 5-7°C, and interbout arousals of less than 24 hours with their body temperature back to 37 ...
Ground squirrels and tree squirrels are usually either diurnal or crepuscular, [24] while the flying squirrels tend to be nocturnal—except for lactating flying squirrels and their young, which have a period of diurnality during the summer. [25] During hot periods, squirrels have been documented to sploot, or lay their stomachs down on cool ...
