State epidemiologist Dave Neitzel says the tick season was delayed by a prolonged winter, but is now upon us. He says ticks are so small they can go unnoticed on people and pets. Neitzel says he was hiking just north of the Twin Cities recently and found some ticks.
A television report from the Twin Cities says the latest data from the Minnesota Department of Health shows nearly 15,000 cases of tick-borne diseases were reported from 1986 to 2010. The majority of the cases were Lyme disease.
