10/25/24 Per the Fairfax County Health Department - students at South Lakes HS were sent the incorrect letter about Pertussis exposure. There has been only 1 confirmed case of pertussis at the school. All students were notified that they were a close contact and to seek medical attention. This is not needed. True close contacts will be notified separately. The health department will be issuing a retraction letter soon and sending the correct messaging.
