The state Department of Public Health is issuing a warning after two children in New Haven County contracted the measles while traveling outside of the United States.
State officials said the two children are under a year old and live in the same house.
The Department of Public Health said any exposures happened within New Haven County between April 11 and 17.
Measles is a highly contagious disease that can spread quickly among unvaccinated people, but most people have been vaccinated or have had measles in the past, before vaccination became routine, according to health officials.
“The single best way to protect yourself and your children from measles is to be vaccinated,” DPH Commissioner Dr. Raul Pino said in a statement. “While most people have had the measles vaccination, it’s important to know your vaccination status and to be aware of the signs and symptoms of measles so you can get medical attention.”
Anyone who is unsure of their vaccination status should check with his or her physician.
Health officials said people who have had measles in the past or who have been vaccinated against measles are considered immune according to the Centers for Disease Control and Prevention.
