Dr. Amy Greer, an infectious diseases modeller in the Department of Population Medicine, spoke to The Globe and Mail about COVID-19 rapid testing in schools.

She said without rapid tests, infected students with no symptoms present a risk to everyone they encounter during the day. But with rapid testing, those who test positive are likely to seek a PCR test and not engage in activities that would put others at risk of infection while they wait for their results.

Greer holds the Canada Research Chair in Population Disease Modelling and is part of a research team modelling COVID-19 spread to advise federal public health authorities.
