My son is concerned he could have got rabies from when we drove over a dead animal on the rode. he is worried he got it from walking where our tires drove than touching his shoes with his hands which have a cut, or from touching his mouth. thanks?

Rabies is only transmitted via the direct contact of saliva or bodily fluids of the infected animal through an open wound such as a bite, scratch or other broken skin. Because this virus dies almost immediately in contact with air, there is no risk of catching rabies from a surface such as you have described.

Rabies transmission is not possible in above circumstances. Check cdc.gov, which has reliable information regarding rabies transmission.
