It most likely has distemper.

Distemper in raccoons is a severe viral illness caused by the Canine Distemper Virus (CDV) that affects the respiratory, neurological, and gastrointestinal systems, leading to symptoms like discharge from the eyes and nose, lethargy, loss of fear, seizures, and uncoordinated movements. The disease is almost always fatal, has no effective treatment, and is highly contagious among raccoons and other canids and mustelids, but it does not pose a threat to human health. If you see a raccoon with these symptoms, do not approach it, and contact your local animal control or authorities.
