The Indiana State Department of Health is now investigating two confirmed and two probable cases of the measles in Central Indiana.
One of the infected individuals was in the Super Bowl Village on Friday.
"There's a remote chance that if you were in the presence or around the person infected and you yourself were not protected either through immunity or vaccination, you may develop measles and we wanted you to be aware of that," said State Health Commissioner Dr. Gregory Larkin.
He said most Americans are vaccinated against measles, but there were visitors from other countries, who may have carried the disease, in town for the Super Bowl events.
"I guess it's good to know it's out there, but my kids are up to date on their vaccinations, so I'm not too worried about it," said Laura Conlon who took her children to the village last week.
Health officials said the infected person did not go into any buildings or to the NFL Experience.
There is some concern more cases could be reported in the next few days because it takes up to a week for symptoms to appear.
"It takes about a week after being exposed and if they're susceptible to getting the measles, they may start off with an upper respiratory infection but later feel more ill with a high temperature. That isn't common with other things so it's important to know about the high temperatures, as high as 105 degrees,"Larkin said.
He said even if you are healthy and didn't go to the Super Bowl Village it's a good time to check if you and your children are up to date on your immunizations.
