Clarification. . . . .only those students who came into "direct contact" (less than 6 ft and for more than 15 minutes) are affected by this.  If your 5th grade child has a school-aged sibling, he/she would be considered a "secondary" contact and are NOT affected. Siblings can come to school tomorrow.  Also, a quarantine lasts 14 days from the last known contact with that person. . . which was Friday.  The Health Department will be contacting you this week to go over the quarantining procedures.  ds
