A new study by investigators with the Centers for Disease Control and Prevention revealed teachers can play a central role in COVID-19 transmission in schools.
The CDC studied schools in Cobb County, Georgia, from Dec. 1, 2020, to Jan. 22, 2021, and identified nine COVID-19 clusters that resulted in 31 cases tied to schools.
Investigators determined two of the clusters were the result of educator-to-educator transmission that eventually spread to students.
Investigators said those two clusters were to blame for half of the 31 school-related cases.
Investigators said all nine clusters involved inadequate social-distancing, and five of the clusters also involved a lack of mask wearing by students.
The CDC concluded that teachers could play a significant role in COVID-19 transmission in schools and recommends vaccinating educators to reduce the risk of in-school transmission.
The CDC has conducted a number of studies and has said schools can reopen safely if the proper precautions are taken.
