PAGO PAGO, American Samoa (AP) — Officials in American Samoa on Friday ordered all public schools in the U.S. island territory closed after nearly 2,300 students and more than 100 teachers contracted pink eye.

The outbreak prompted the closure of 28 schools from preschool through high school, plus preschool and special education programs, and they will not reopen until Wednesday. Some private schools were also closed and court cases postponed because of pink eye.
