CDC study: Teachers key to COVID-19 infections in 1 district
A new study finds that teachers may be more important drivers of COVID-19 transmission in schools than students.
The paper released Monday by the U.S. Centers for Disease Control and Prevention studies nine COVID-19 transmission clusters in elementary schools in the Atlanta suburb of Marietta in December and January, That included one cluster where 16 teachers, students and relatives of students at home were infected.
In only one of the nine clusters was a student clearly the first documented case, while a teacher was the first documented case in four clusters. In another four, the first case was unclear. Of the nine clusters, eight involved probable teacher-to-student transmission. Two clusters saw teachers infect each other during in-person meetings or lunches, with a teacher then infecting other students.
