The school vice-principal Ilze Sondore-Drukaļska said that the school had received a call from the pupil's mother that she'd had a positive COVID-19 test. Her child, though not displaying any symptoms, was tested and the result had been positive. He had not come to school since Monday, September 7.
From Monday, the pupil's 14 classmates and four teachers who had been in contact, are in quarantine. Learning for them takes place remotely.
Altogether, the school has around 500 students. There is no cause for concern, said the vice-principal. Disease Prevention and Control Center (SPKC) had allowed continuation of work.
"We are tracking the route of infection. We can say it is not related to the school and not to travel," said SPKC spokeswoman Ilze Arāja.
The classroom where the pupil and his classmates had been was disinfected and is closed for use for two weeks.
