If you suspect measles, seek medical treatment as soon as possible. This is not a matter of food safety or restaurant sanitation; the individual with measles was a customer at these restaurants while contagious.
Three cases were confirmed earlier this week, and at the time health officials warned that other cases could follow since the children were treated in an emergency room.
The CDC has reported that between January 1 and March 25 of this year 28 people have been diagnosed with measles.
"This outbreak is about unvaccinated children, not specific communities", said Minnesota Health Commissioner Dr. Ed Ehlinger, according to StarTribune.
Measles is a viral infection. It also can cause miscarriages or premature delivery in pregnant women.
Measles is highly contagious and can be passed through the air by coughing and sneezing. She says measles has an incubation period of about two weeks and is highly contagious. The illness starts with a high fever, runny nose, cough and reddened light-sensitive eyes.
Individuals may be contagious for a few days before they present with symptoms, which increases the potential of exposing others to the infection.
"Measles can spread easily among unvaccinated people, and we're working with the Somali community in the Twin Cities to alert people to the outbreak", Infectious Disease Division director Kris Ehresmann said in a Friday statement.
Seven of the confirmed cases are Somali Minnesotans.
From 2001 to 2012, the average number of measles cases in the Unites States per year was about 60, but there have been more cases in recent years, which is of great concern to public health authorities. In 2014, there were 667 cases nationwide, including five cases in MI. The vast majority of people who get measles have not been vaccinated against it. The MDHHS says that the best line of defense against measles is vaccination.
Washtenaw County health officials said one of the affected people, while contagious, dined recently at two Ann Arbor restaurants, both near University of MI campuses.
The vaccination, or documentation of immunity to measles, is recommended for all persons travelling internationally, Wells said.
