An unvaccinated Hartford County adult has been diagnosed with the state's first confirmed case of measles this year, the Connecticut Department of Public Health announced Monday.
DPH officials say the resident recently traveled internationally and began showing symptoms of measles after returning. They say the travel is not related to the World Cup.
The person’s symptoms include fever, sore throat, cough, runny nose, diarrhea and rash. They are currently hospitalized but stable.
Measles is highly contagious and can spread through the air when an infected person coughs or sneezes. According to the Centers for Disease Control, nine out of 10 unvaccinated people who encounter an infected person will become infected.
Symptoms begin seven to 14 days after a person comes into contact with an infected person. Officials say people with measles first experience a fever, cough, runny nose, red eyes and a sore threat. Three to five days later, a red or reddish-brown rash appears.
"Vaccination continues to be the best way to protect yourself and your family from measles. One dose of measles vaccine is about 93% effective, while two doses are about 97% effective. Being vaccinated helps us all protect those who matter most," DPH Commissioner Manisha Juthani said.
DPH officials say so far in 2026, there have been 2,073 cases reported nationwide. They say Connecticut is one of the last states in the country and in New England to have a confirmed case this year.
In the past five years, Connecticut only had two positive cases of measles. In both cases, the people were unvaccinated and had just returned from international travel.
