MANHATTAN, Kan. (AP) — A Kansas State University laboratory that conducts rabies testing is reporting a spike in positive results.

Diagnostician Rolan Davis says there were 28 positive rabies cases from January through March of this year, up from 10 positives for the same three months in 2014.

The school said this week in a news release that 23 of the cases involve rabies in a skunk, the animal most associated with carrying the virus in Kansas. There also were three cases in cats, one in a bovine and one in a fox.

Davis says the increase isn’t a cause for alarm but urged people to be aware in case they come across an infected animal. Officials at the Kansas State Veterinary Diagnostic Laboratory say vaccinating pets is the best protection against rabies.
