What we know right now The new coronavirus—also known as 2019-nCoV—which is believed to have jumped from animals to humans in Wuhan, China, is now spreading among humans, as some people who haven’t visited China are getting sick. It has officially infected more than 6,000 people, most of whom are hospitalized in Wuhan and surrounding cities.On Saturday, health officials announced that the first case in Canada had been discovered in Ontario.
What is the coronavirus? 2019-nCoV, a coronavirus strain, was first detected in humans in Wuhan in mid-December among a cluster of individuals who showed up at the hospital with coughs, difficulty breathing and fevers. Initially, the cases could all be traced back to a seafood and meat market in Wuhan, where live animals were being sold. This led authorities to conclude the virus had jumped from animals to humans.
If left untreated, however, 2019-nCoV can advance to pneumonia, kidney failure or other complications, which is why it is dangerous to the elderly and people with compromised immune systems. What isn’t known is how easily it can spread. But public health authorities are concerned by how quickly the number of confirmed cases is rising. Just five days ago, there were 40 known cases in China. As of the afternoon of January 21, there were around 275 cases and counting. Given that there’s a long incubation period, there could be many more currently infected who haven’t shown symptoms yet. Some epidemiologists estimate the actual number of cases could be closer to 2,000.
Has it been found in Canada? Yes. So far, three cases have been announced by public health officials. A man, 50, arrived from Wuhan to Toronto last week, showing mild symptoms on the flight and was tested positive for 2019-nCoV when his condition worsened soon after. His tests have been confirmed by a lab in Winnipeg. His wife is the second case, and her tests have also been confirmed. There was a third presumptive case announced in B.C.
