I work in the public health system and this is way more dangerous than the normal flu. It’s arithmetic, on average a carrier infects 3 people instead of an average of 1.4 for the season flu. Extrapolate that out over time and you have your answer.
BTW the public health system ramps up to an enormous extent to handle the flu season every year.
If you don’t want to believe it then it’s up to you.
The WHO has already said explicitly that COVID does not spread as fast as the flu. Directly from the WHO situation update on 6th March.
Yes the RO for COVID is about double the flu, which means you can pass it on to twice as many people.
BUT
The incubation period is longer, which means it takes longer before you can pass it on,
and
Pre-symptomatic transmission of the flu is likley, whereas pre-symptomatic (and asymptomatic) cases are not seen as major drivers of transmission of COVID
and
Socially mobile children who are important links in flu transmission do not appear to important in COVID transmission.
The maths says you might pass COVID onto twice as many people as the flu, but you will pass the flu on more than twice as fast which is why the WHO can confidently and explicitly say
"This means that influenza can spread faster than COVID 19".
