(CNN) A Southern California day care has shut down because an infant there -- who's too young to get vaccinated -- contracted measles, another case in the re-emergence of the disease on the West Coast.

The Samohi Infant Toddler Center inside Santa Monica High School, a facility for 24 young children of students and staff members, closed Monday after it was learned that a baby under 12 months old being care for there had measles. It's not clear when, where or how the child got the disease.

Nor is there any timetable for when the center will reopen, but it's possible that children who have been immunized against the highly contagious virus could soon go back.

In addition to the baby with measles, 13 other infants who went to the day care center are being quarantined for 21 days as a safeguard.

"It's the best thing to do to protect the babies and the community," Santa Monica-Malibu Unified School District spokeswoman Gail Pinsker said of the closure. "It's a tough situation."
