An unvaccinated elementary school teacher in California infected more than half of her students with COVID-19, ultimately resulting in a community-wide outbreak in Marin County, a report from the Centers for Disease Control and Prevention found.

Why it matters: The outbreak, which took place in May, highlights the stakes surrounding a debate across the U.S. among school districts considering implementing stricter measures to curb the spread of the virus, like universal masking in schools.

Details: The teacher who caused the outbreak continued to show up at school for two days while experiencing symptoms before ultimately receiving a test.

  • The school in question requires teachers and students to wear masks indoors. But the teacher read to her students unmasked as she exhibited nasal congestion and fatigue.

  • The teacher tested positive for the virus on May 21, and 12 of her 22 students later tested positive, per the report.

The big picture: Thousands of students were forced to quarantine or isolate due to possible exposure almost immediately after schools reopened in August. Districts have had to temporarily close schools or suspend in-person instruction because of outbreaks.

What they're saying: The outbreak "highlights the importance of vaccinating school staff members who are in close indoor contact with children ineligible for vaccination as schools reopen," the report read.
