SAN DIEGO -- A doctor's office appears to have been a center of infection in a measles outbreak in San Diego.
County health officials said there were 10 confirmed and suspected cases of measles, the San Diego Union-Tribune reported. The first child, who is believed to have been infected in Switzerland, was treated at a doctor's office and is believed to have spread the infection to six more children there.
More than 50 children at a school, a daycare center and a swim school have been quarantined because they have had contact with one of the infected children and have not been vaccinated for measles.
One 11-month-old child was diagnosed in Hawaii after flying there, KGTV reported. The baby was in isolation in a military hospital in Hawaii.
Measles, once common in the United States, has become rare since a vaccine was developed. Health officials say too many parents are opting out of vaccination.
