Thought it was not clear if the case was included in Saturday's count, a letter sent to Allen ISD parents and guardians Thursday confirmed a student who participated in the Performance Course program had tested positive for the coronavirus.
The athlete participated in activities twice this week, but was not there Thursday after learning of the positive test, according to the letter.
Athletes in the student's cohort group have been notified and those who came in contact with the student will not be allowed to participate in workouts until they have completed a two-week self quarantine and are free from symptoms.
The letter stated that the district is undertaking deep cleaning measures, and will continue to implement safety measures and procedures, including daily health screenings and a temperature check before workouts.
Students participating in on-campus workouts are asked to stay home if they have any of the symptoms of COVID-19 or if they have been in close contact with someone who has the virus, the letter said.
Allen ISD is the latest district that has had students participating in summer workouts test positive for the coronavirus.
On Sunday, Carroll ISD notified parents of a second athlete who had attended the high school workouts who had tested positive. The student had been in multiple workout cohorts last week, including a small group of three with Performance Course, a group of six in one sport and a group of eight in another sport.
The district said the athlete, who was not symptomatic during the workouts, had not had contact with the first positive case.
Athletic Director Steve Keasler said in the the letter to parents, students and staff that there was no reason to think either athlete contracted the virus at the workouts.
Performance Course's website includes a list of social distancing policies for athletes and staff.
