Press release from the Wayland Health Director, April 25, 2012:

We received confirmation today that a raccoon obtained from North Wayland off of Concord Road and Lincoln Road tested positive for rabies.  When an animal tests positive for rabies it is likely that there are other animals in the area that are carrying the disease.  Rabies is a serious disease that is usually a disease of animals but it can spread from an infected animal to a person.  Rabies is spread when an animal with rabies bites another animal or person.  Infected animals can also spread rabies from their saliva.  Residents should not approach any wild or stray animals and report any animal that behaves oddly to the Police Department.  Also, ensure that your pets are up to date on their vaccinations against rabies, keep pets in a fenced yard or on a leash, don’t feed or water your pets outside, and keep garbage securely covered.  Open garbage will attract wild or stray animals.
