The CDC warns of a measles outbreak across the United States.
In Wisconsin, physicians at ThedaCare say the public needs to take caution as states like New York, Washington and Texas experience high numbers of cases.
Doctors say the outbreaks are due to people being unvaccinated.
“Since Wisconsin is only about 87 percent immunized, there's a good chance it's going to come up here because you need 95 percent of the population to be immunized to be protected,” said Dr. Sharon Rink.
Dr. Rink says those numbers mean one or two kids in every classroom could be unvaccinated.
Immunizations can prevent measles. Doctors say the disease spreads quickly and easily through coughing and sneezing.
