Illinois Department of Public Health is urging some travelers to be tested for measles after officials confirmed a passenger traveling through Chicago O'Hare International Airport tested positive for the infection. 

According to the department, on Jan. 10, the passenger arrived from an international flight in Terminal 5 and departed on a domestic flight from Terminal 1.

The passenger was infectious on that day and may have been in multiple areas of the airport between flights. Measles is highly contagious.

If infected, you could develop symptoms as late as Jan. 31, according to the health department.

The health department said most people are vaccinated during their childhood and are not at risk. However, if you are not vaccinated, you could be at risk.

Officials at the St. Louis International Airport issued a statement Monday regarding procedures for potential or confirmed cases of infectious diseases at the aiport:

“The Airport has emergency operational plans and guidelines, approved by the FAA, in how to respond to infectious disease cases. Those plans include notification procedures to St. Louis City and St. Louis County Health Departments and coordinating response and or treatment guidance with local hospitals. All procedures in responding to such cases are based on protecting the health of passengers, employees and the public with as much urgency as possible.”

If you think you may have been exposed to measles, contact your doctor.

Symptoms of measles include rash, high fever, runny nose and red, watery eyes. Measles can cause serious illness such as pneumonia and swelling of the brain.

Measles is easily spread through the air when an infected person coughs or sneezes. It can also be transferred through mucus or saliva.

Local health departments are working to notify people who were on the infected person's flights.

Measles symptoms could come on as late as Jan. 31, 2018. Airport officials have not said what city the person traveled to after Chicago.
