Over 60,000 people have already had the virus and recovered.
More people in China have now recovered than are infected.
It's not significantly different than a flu.
Old people in bad health die when they get the flu too.
Italy has had significantly hirer flu deaths rates too compared to most developed countries. Because their population is older and less healthy to begin with.
They don't die at this high of rate though. Even the most conservative estimates say it has a ten times higher mortality rate than the flu. And it spreads fast. One of the biggest worries as well is that hospitals wouldn't be able to handle all the cases if you just let normal activity continue.
