They dont carry rabies.
Any mammal can get rabies. From what I read it's fairly rare in opossum. However they are nocturnal and I could never find a complete explanation for seeing them in broad daylight on a beautiful spring day.
Question: If opossums are nocturnal then why do I see one in the day?
Answer: There are a number of reasons for opossum sightings during the day. If it is winter in an extremely cold area, usually covered with snow, then the opossum may be hungry. It is often difficult for an opossum to find food in extremely cold, snowy areas. During sever weather the opossum may stay in a den a few days until hunger drives it out of hiding. The opossum may have to forage for food during the day, often while it is warmer. During the spring or summer months a female opossum laden with young must spend more time foraging for food and may be seen during the day. Also, an opossums daytime hiding area may be disturbed, often by the presence of a dog or children throwing a ball into a bush. The frightened animal will run out and search for a new hiding place. Other possibilities include a blind opossum or a sick or injured opossum. If you suspect the opossum is not healthy then contact a local wildlife rehabilitator.
