Contagion alert to measles by an infected person at Chicago Midway Airport


Officials warned of the risk of a measles outbreak after an infected passenger flew last Friday to Chicago International Airport.

The Illinois Department of Public Health warned Thursday that people "may have been exposed to measles" if they were at the airport between 9pm and 9pm. and at midnight on February 22nd.

The department warned that people might not feel the symptoms of the disease until March 20, because of its long incubation period. Experts say the virus can infect people as early as four days before the onset of symptoms.

The disease is spread by air, which can remain contagious until two hours after the departure of an infected person, according to US Centers for Disease Control and Prevention.

Symptoms of measles include high fever, rash, cough, runny nose, and red, watery eyes. There is no specific treatment, although doctors may prescribe medication to alleviate symptoms.

In rare cases, measles can kill. A small percentage of people who suffer – about one in every 1,000 – develop encephalitis, or swelling of the brain, which can lead to long-term brain damage and death.

An Illinois health official said in a statement: "Most people are routinely immunized in their childhood and are not at high risk." The most troubling people are the people who have not not been vaccinated. "

The infected passenger was "unvaccinated and contagious," officials said. The person had arrived from another country where measles is more prevalent, according to the statement, without however specifying which country.
