    Chicago and Cook County health officials said Tuesday that nine of the 10 cases are associated with a KinderCare Learning Center in Palatine. All of the cases are among unvaccinated infants and adults.

    According to Elgin Community College, a student from Cook County has a confirmed case of measles. The school says that before diagnosis, the student attended classes on Feb. 3 and Feb. 5 and visited the library on Feb. 3.

    Public health nurses have been in daily contact with families of infants enrolled at the day care who may have been exposed to the contagious virus.

    Dr. Julie Morita of the Chicago Department of Public Health says the cases show the importance of maintaining high levels of vaccination.

    The government recommends a first dose of measles vaccine for children ages 12 months to 15 months, with a second dose before starting kindergarten.

    Symptoms of measles include fever, red and sore eyes, runny nose, cough, and rash. Measles can cause more severe health problems, including pneumonia, encephalitis, and death; it is transmitted by coughing and sneezing, and can survive in the air and on surfaces for up to two hours. People who have measles are contagious from four days before a rash starts, through four days afterward.
