The science has evolved since the virus first emerged

It’s hard to remember a time when we could get as close as we wanted to our friends without fear of getting sick.

Since March, the message has been drilled into us: wash your hands and keep your distance.

As experts learned more about COVID-19, they told us to wear masks indoors.

How do masks help contain the virus, anyway?

Jason Kindrachuk, a researcher and assistant professor at the University of Manitoba, has been working in a lab to learn more about COVID-19 for several months.

“The science has certainly changed a little bit from, say, early springtime and late winter to now,” he said.

At the beginning, we thought the virus spread on surfaces.

That means you could catch it, for example, by touching a surface where the virus lived and then touching your face.

“It can still happen, but we don't think it's driving the pandemic,” Kindrachuk said.

Droplets are the main cause

Now, researchers have found out that the virus mainly spreads through droplets.

That means that if you have COVID-19 and you sneeze, cough or yell, tiny droplets that you can’t see are flung from your nose and mouth.

They hang in the air for a few seconds before they’re pulled down by gravity.
