Mass. Students Quarantined In China

Three Massachusetts high school students and one chaperone have been quarantined in China after one of the students was diagnosed with a possible case of swine flu.

St. John's High School, a Roman Catholic school in Shrewsbury, said in a statement that 12 other students, as well as another chaperone will continue with the school-sponsored trip that started June 11.

The school said it will continue to "closely monitor" the situation and keep parents informed. The school did not disclose the names of the students or chaperone.

Headmaster Michael Welch did not immediately return a message left at his office Thursday.

The school about 35 miles west of Boston has nearly 1,000 students.

Numerous travelers have been quarantined over swine flu concerns in China, including other school groups from California and Maryland.
