Two teachers and 18 students from various schools in the northern Vietnamese province of Ha Nam have tested positive for COVID-19.
The Ha Nam Center for Disease Control confirmed on Wednesday evening it had detected 20 local COVID-19 infections in Phu Ly over a 24-hour period.
These cases included a teacher at Tran Quoc Toan Elementary School, a homeroom teacher and 16 seventh-graders from the same class at Tran Quoc Toan Middle School, and two fifth-graders at Liem Chinh Elementary School.
The patients are being treated at the province’s Tuberculosis and Lung Disease Hospital.
Competent authorities have so far identified 120 direct contacts of the 20 cases, most of whom are students.
They will be allowed to quarantine at home, according to Nguyen Duc Toan, secretary of Phu Ly City’s Party Committee.
If their houses do not meet requirements, they will be quarantined at school or at local hotels, Toan added.
Ha Nam has recorded 112 local coronavirus infections since the fourth wave hit Vietnam on April 27.
As the province was at low risk of transmission, local students were allowed to attend school in person when the 2021-22 academic year began in early September.
However, they were told to stay home from September 20 to 26 following the detection of more than 10 community-based cases, according to VnExpress.
