Measles cases in Illinois UPDATE and attendance at Chicago area soccer game – IDPH alert

The following is an IDPH alert released on July 17, 2013.

The Illinois Department of Public Health, along with the Centers for Disease Control and Prevention and local health departments, have been investigating two additional cases of measles who traveled from Germany/Poland to Illinois in late June. This brings the total to three cases in Illinois residents from the same family and two cases among family members who are international residents. The investigations are still ongoing, but it appears all cases are related to importation.

One of the newly diagnosed cases attended a Chicago Fire soccer game on July 7, 2013 in Bridgeview, Illinois and travelled through O’Hare International Airport (Terminal 3) on July 8 which would have been during the case’s contagious period. With an incubation period of 7 to18 days for measles, potential cases infected from either exposure would likely show symptoms between July 14 and July 26. If someone presents with measles-like symptoms with either exposure, follow isolation guidelines to prevent further spread and contact your local health department or IDPH as soon as possible.

Measles is a highly contagious viral illness that is characterized by a rash, fever, cold symptoms, conjunctivitis, malaise, and Koplik’s spots (tiny white spots with bluish-white center inside the mouth). Measles should be considered as a diagnosis in persons with no proof of immunity* to measles and presenting with a febrile rash illness as described above and a history of attendance at the Chicago Fire game on July 7, travel through O’Hare Terminal 3 on July 8, recent international travel or contact with travelers or other persons with rash illness.

Physicians and other health care providers, as well as laboratories, should report a suspected measles case to their local health department as soon as possible but within 24 hours. Local health departments should report cases to the IDPH CD Section within the same time period.

Please contact the IDPH Communicable Disease Control Section at 217-782-2016 if you have any questions.

*proof of immunity includes: documented receipt of 2 doses of MMR vaccine; blood test that show immunity to measles; documentation of physician diagnosed measles; birth before 1957
