School staff just as likely to get COVID-19 from community as they are from work, study suggests
Federally funded study shows limited chance of developing disease through contact in school, researchers say
A study of school staff in Vancouver says their risk of developing COVID-19 through contact at school is identical to their risk of catching the virus in the community.
The study by researchers from B.C. Children's Hospital, the University of British Columbia and Vancouver Coastal Health examined COVID-19 infections among teachers and staff throughout the Vancouver school district.
Blood samples taken from 1,556 staff showed 2.3 per cent tested positive for antibodies to the coronavirus that causes COVID-19, mirroring the number of positive tests from a matching group of donors who did not work in schools.
Researchers say the findings show the limited chance of developing COVID-19 through contact in a school setting.
The study has not yet been peer reviewed but was published in preprint form in order to share the details quickly.
Dr. Louise Masse, the article's co-lead researcher and a professor in the School of Population and Public Health at UBC, says it's hoped the findings will guide future decisions about school openings and closures.
Vancouver School District superintendent Suzanne Hoffman says it's important schools stay open, not just for learning but for the social, mental and physical well-being of students.
"These results reaffirm that with the protocols we have in place, schools are safe places to teach and learn," she said in a statement.
The study was funded by the federal government through its COVID-19 Immunity Task Force.
The Vancouver school district has an annual enrolment of around 50,000 students from kindergarten through Grade 12.
