When you test is very important since different versions of the virus produce varied viral loads, according to Furness.
"Now, it's pretty difficult to get a positive test when symptoms first appear; you usually have to wait a few days," Furness explained.
"You can also have a negative test and still be infected because you're not contagious or not contagious enough to induce a positive test."
According to Furness, swabbing not just your nose but also your throat is the greatest approach to accurately test and obtain a reliable result amid swirling sub-variants.
According to Samantha Yammine, a scientific communicator in Ontario, rapid tests detect a component of the virus known as the nucleocapsid protein.
"I believe they can still assist us traverse this phase of the pandemic if used properly."
Although research on quick testing and COVID-19 variations of concern is sparse, what has been done demonstrates that they are still effective.
According to a research published in September in The BMJ, a peer-reviewed medical trade publication, just one out of three tests tested demonstrated a significant statistical drop in sensitivity during the original Omicron variant.
The virus is still a public health emergency of international concern, according to the World Health Organization on Wednesday.
