Global News shows that just as vaccination drives are picking up steam across Canada, deadlier and possibly more transmissible COVID-19 variants are spiking up infection rates among Canadians.
New variants first detected in countries like Brazil, South Africa, Nigeria and Britain have cropped up spontaneously in Canada over the last year. All share some of the same mutations in the region of the virus used to enter and infect cells.
COVID-19 vaccine supply ramp up is expected in the coming weeks, and as Eric Sorensen reports, that could make a big difference in the race between vaccines and variants.
Many different "coronaviruses" are out there. Six species of human coronaviruses are known, with one species subdivided into two different strains, making seven strains of human coronaviruses altogether.
COVID-19 is an illness caused by a coronavirus. Human coronaviruses are common and are typically associated with mild illnesses, similar to the frequently happening common cold.
The flu and COVID-19 are caused by different viruses. This means that the flu shot will not protect you against COVID-19.
The COVID-19 virus is an enveloped virus, with a fragile outer membrane. Generally, enveloped viruses are less stable in the environment and are more susceptible to oxidants, such as chlorine.
Some people may have thought the temperature numbers change the dangerous virus. From the evidence so far, the COVID-19 virus can be transmitted in everywhere, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose. Use hand sanitizer.
