The CDC is keeping its eye on a measles outbreak that covers at least 21 states, including Indiana.
According to the CDC, 107 people contracted the disease from January 1 to July 14 of this year.
There were only 118 cases of measles in the U.S.in 2017 and 86 in 2016.
In Michigan, four cases have been reported this year.
But that is no longer the case, which is why the state is urging people to stay up-to-date on the recommended vaccines.
The symptoms of measles generally appear about seven to 14 days after a person is infected.
Measles is highly contagious. It is likely that the number of cases in 2018 will be much more than that. A rash follows three to five days after the initial symptoms.
Some people may suffer more severe complications: ear infections, pneumonia and encephalitis (swelling of the brain which occasionally develops 5-10 years later), these unfortunately may result in prolonged hospitalization or even death.
He was not surprised though to hear about a measles outbreak because they are seeing rising rates of people not vaccinating their child. Children with measles must be kept out out school to limit the spread of the virus.
How can you avoid getting measles? Vaccination is now the only effective way to prevent measles. The CDC says two doses of MMR vaccine are about 97% effective at preventing measles; one dose is about 93% effective. The CDC didn't say how many of those cases were in Kansas.
