During the busy holiday travel season, a measles case was detected at Newark Liberty International Airport in New Jersey. The infected person was at terminals B and C on December 12, according to the New Jersey Department of Health (NJDOH). Measles spreads easily through the air when an infected individual coughs or sneezes. The virus can stay in the air for up to two hours after the person leaves. Symptoms of measles include high fever, cough, runny nose, watery red eyes, and a rash starting on the face and spreading down the body. NJDOH advised anyone who thinks they were exposed or shows symptoms to contact their doctor before visiting clinics or hospitals. The NJDOH is working with local officials to track contacts and notify those possibly exposed. People not fully vaccinated or never infected are at higher risk. New Jersey reported 11 confirmed measles cases this year. Nationwide, the Centers for Disease Control and Prevention (CDC) had recorded 2,012 measles cases as of December 23. Holiday travel is at its peak with a record 8.03 million expected to fly, raising the risk of exposure in crowded airports and planes. On Christmas Eve, Massachusetts health officials confirmed a measles case at Boston Logan International Airport from a traveler arriving from Dallas-Fort Worth. Connecticut’s DPH Commissioner Manisha Juthani, MD, told The New York Post, "The single best way to protect your children and yourself from measles is to be vaccinated. One dose of measles vaccine is about 93% effective, while two doses are about 97% effective."
