1 Multiple sclerosis (MS) is a disease that causes demyelination (disruption of the myelin that insulates and protects nerve cells) of spinal nerve and brain cells.  Although the exact case is unknown, multiple sclerosis is considered to be an autoimmune disease.
The skunk is not a rodent. They belong to the family Mephitidae and the order Carnivora which does not include rodentia. They are sometimes placed in the family Mustelidae (weasels) but have been discovered to be less related than was thought.
While humans are most likely to contract rabies from dogs or bats, in most of North America dogs and cats are most likely to contract rabies from skunks. Getting sprayed by a skunk makes your pet extremely smelly but does not cause any risk of the disease.
