Avian virus

The infection is transmitted through the bites of rabid birds. The virus causes extensive mutation in the human body: the growth of feathers all over the body, deformation of the skull and an increase in muscle mass.

TO AVOID INFECTION, IT IS NOT RECOMMENDED TO HAVE CONTACT WITH WILD BIRDS!
