Rapid tests can be used for added protection over holidays, but experts warn they aren't perfect

As concerns over the spread of the new Omicron COVID-19 variant seep into Canadians' holiday plans, experts say rapid tests could be used to help protect those looking to get together with friends and family. However, they say the tests should be used in conjunction with current public health measures.

Dr. Nitin Mohan, an epidemiologist and assistant professor at Western University, told CTVNews.ca that rapid antigen tests, which can provide on the spot results in about 20 minutes, can "absolutely" be used to further protect Canadians who plan to spend time with family and friends this holiday season.

"What rapid tests do is they provide an indication of someone's status at that time," Mohan said in a telephone interview Monday. "[It] provides an extra layer of data that gives you an idea of where you're sitting in terms of the possibility to transmit the virus to those who are more vulnerable."

However, Mohan said rapid tests are "only one of many layers of protection" against COVID-19 and do not replace vaccines. He says those looking to gather over the holidays should be fully vaccinated and have a booster shot if they are eligible.

"Omicron, if not now, very shortly will be the dominant strain in Canada," Mohan said. "So if you want to be extra cautious taking a rapid test prior to the event to ensure that you know you are not transmitting the virus to anyone that's there, I think that's a good idea."
