Health officials in Arizona, host state of Sunday's Super Bowl, have asked people who may have been exposed to measles to isolate themselves, The Arizona Republic reports. Game attendees are not at a high risk of contracting the disease since most Americans are vaccinated against it, according to the CDC.
Seven cases have been confirmed and 1,000 people across three counties may have been exposed, the newspaper said.
Two of the seven confirmed cases are in Maricopa County, which is hosting the NFL championship game, the county's health department confirmed Tuesday.
Because the highly contagious virus can linger in the air for two hours, health officials have asked those who may have been exposed to avoid doctors' offices, emergency rooms or urgent-care centers, the newspaper said.
"Anybody who is unvaccinated or undervaccinated (received only the first of two recommended doses) who has been exposed to measles patients, needs to be in isolation for 21 days," said Will Humble, director of the Arizona Department of Health Services, according to the newspaper.

Residents of Maricopa County have not been advised to wear masks or avoid public transportation, according to Bob England, the county's public health director. "I don't want people to change their lives," he told the newspaper. "If you go out in public, you are way more likely to get the flu. What we're trying to do is nip this in the bud, track people who've been exposed, keep them out of child care and work, so it doesn't become widespread."
The department did not immediately respond to CNBC's request for comment.
