An earlier response contained a potentially dangerous tidbit of misinformation. Opossums CAN get rabies. Any mammal can get/carry rabies. It is just that some species' behavior makes them more prone to infection - raccoons, skunks, etc. Possums aren't the usual suspects and that one looks fat and healthy.
yes, opossums can get rabies (and for the record, are not technically mammals). However, technically speaking, so can a squirrel (why don't we consider squirrels rabies carriers? Because the chances of a squirrel surviving the attack of a rabid animal are incredibly slim).
The difference is that the only documented
confirmed case found that was presented in the rabies training course sanctioned by the state of Texas, and that I am required to take for my job in order to retain my certification was a case in which the opossum was bitten directly on the head, and the virus was intruduced directly to the brain tissue of the animal. Short of this unlikely scenario, opossums are NOT considered carriers for the virus. They are highly unlikely to
pass it on or even be affected by it even if the virus is introduced into the opossum's body.
Opossums are fairly primative animals, and their neurologial systems are quite simplistic when compared to modern mammals. These neuro pathways are what the rabies virus uses to make it's way to the brain of the host animal. In combination with minimal neuro pathways, and low body temps as brought up by aprophet, the opossum is rendered a very poor and unlikely host for the rabies virus. IE-opossums are not considered
carriers of the virus any more than squirrels, rabbits, or rats are considered carriers.
CDC has a really hard time finding possums with rabies the body temp is lower then it takes for the virus to incubate, around here bats and skunk are tied for the number 1 vector
