An unvaccinated teacher who periodically removed her mask to read to students started a COVID-19 outbreak at an elementary school in Marin County, California, that eventually infected 22 students and four of their parents.
cases, children's mental health issues, and rising COVID-19 infections in children that may threaten bed capacity.reported that as of the end of July 2021, less than 1 in 3 adolescents ages 12 to 17 had been fully vaccinated against COVID; about 42% had received a single dose.
In addition to cases in this class, there were six cases in a different grade at the school. Gene testing revealed the strains infecting the kids in these two grades were identical, suggesting they were part of the same outbreak. The study authors say that they aren't sure how the virus passed from one grade to the other, but believe it was passed through kids interacting with each other at school.
Only 463 school-associated cases were reported among students attending public K-12 schools in Los Angeles County during the last school year, but this was a period when many students were given the choice to remain at home with online classes. The period of the study covers September 2020- March 2021, and doesn't reflect the impact of the Delta variant, the study authors write.
But others have argued that the rise in cases is happening despite schools relying on and following the CDC's guidelines, particularly guidance that children can safely be spaced at least 3 feet apart to reduce transmission.
