The student who had the confirmed case attends Sequoya Middle School in Holtsville, the district said in a letter to parents dated Tuesday and posted on the Sachem Web site. The student with the possible case attends Sachem High School North in Lake Ronkonkoma.

Both students stayed at home while ill and have fully recovered, according to the district.
