The Health Department confirmed Tuesday that a previously unvaccinated 2-year-old has contracted measles on Oahu apparently from an 11-month-old baby who caught the disease on a trip to the Philippines.

The toddler was exposed to the disease Feb. 7 while visiting a local pediatrician’s office at the same time as the baby who later turned out to be infected, according to Dr. Sarah Park, state epidemiologist. She did not disclose the location of the doctor’s office.

Measles is a highly contagious disease and anyone who is not vaccinated is at risk. Patients are contagious starting four days before the onset of the measles rash.

Symptoms of measles include a blotchy, red rash, fever, cough and runny nose, according to the Health Department. They tend to appear about 14 days after a person is infected.
