Now, tell me which flu virus causes such a rapid tragedy. Because that's the difference (now I'm going down a bit in the technical field): in the classical flu, apart from infecting much less population over several months, cases can be complicated less frequently, only when the VIRUS destroying the protective barriers of the Our respiratory tract allows BACTERIA normally resident in the upper tract to invade the bronchi and lungs, causing more serious cases. Covid 19 causes a banal influence in many young people, but in many elderly people (and not only) a real SARS because it arrives directly in the alveoli of the lungs and infects them making them unable to perform their function.
Take away: The regular flu is MUCH less infectious. The regular flu has much less complications (pneumonias) because it targets the upper respiratory and only infrequently travels lower. The corona virus heads straight for the lungs and if you're not in optimal health you're going to be severely affected.
BS, millions are infected with the flu every flu season, while we have less than 200,000 reported infections by coronavirus. The deaths in just this country, from the flu, is around 20,000 so far. That's 5 times the number of those who have died from the coronavirus worldwide.
