Health officials in suburban Cook County, Illinois, have confirmed the second case of measles this year. The latest case involves a 4-year-old child who is unvaccinated and is believed to have contracted the virus during international travel. The Cook County Department of Public Health (CCDPH) is working closely with the Illinois Department of Public Health and the Chicago Department of Public Health to identify and notify individuals who may have been exposed.
Potential Exposure at O’Hare International Airport
Public health officials have identified a potential point of exposure at O’Hare International Airport. Individuals who were in Terminal 5 between 7:30 a.m. and 11:00 a.m. on Thursday, September 11, may have been exposed to the measles virus. Measles is highly contagious and can spread through the air when an infected person breathes, coughs, or sneezes. The virus can linger in a room for up to two hours after an infected person has left.
What to Do If You Were Exposed
Health officials advise individuals who may have been exposed to check their vaccination status. If unsure about prior vaccination, it’s important to consult with a healthcare provider. If symptoms develop, such as a rash, high fever, cough, runny nose, or red, watery eyes, individuals should contact their healthcare provider before visiting a medical facility to prevent potential exposure to others.
The MMR (measles, mumps, rubella) vaccine is the best defense against measles. Two doses of the MMR vaccine are considered 97% effective in preventing measles. The first dose is typically administered between 12 to 15 months of age, with the second dose between ages 4 to 6.
Ongoing Efforts and Recommendations
The CCDPH continues to monitor the situation and is working to identify and notify individuals who may have been exposed. Health officials emphasize the importance of vaccination, especially for travelers, to prevent the spread of measles. Individuals planning international travel should ensure they are up to date on their vaccinations and consult with their healthcare provider about any additional precautions.
Measles was declared eliminated in the United States in 2000, but recent years have seen a resurgence in cases. This underscores the importance of maintaining high vaccination coverage to protect public health.
