"The most recent notice said:" A letter was sent to the Miner Primary School community on April 2, 2021, informing them that when students were present on April 2, 2021, a positive COVID-19 case occurred in the building. Since the school reopened for face-to-face learning in February, the school system has issued about 100 notices, making the school system’s population approximately 20%. Each posting may mean that at least one classroom (up to 12 people) must switch to distance learning and be isolated for two weeks. These notices may be worrying, but city officials said they reflect more that students are bringing the virus into schools, rather than that the virus is spreading in schools. School system officials say that when multiple people in the school test positive, they are usually siblings in different classrooms of the school.
