Here is my impression on why people should take it more seriously and not compare it to the flu.
The flu kills about 0.1% of people who get it. COVID-19 kills closer to 2-4%, making it 20-40 times more deadly.
COVID-19 is more contagious. The flu has an R0 of about 1.3, meaning for ever 1 person who gets it, they infect 1.3 new people (so if 3 people have the flu, then infect 4 more). Because of this, about 10% of America gets the flu each year (around 30 million people). COVID-19 has an R0 of closer to 2-3, and there are predicts that anywhere from 20-70% of Americans will catch the virus before this is all said and done.
If you do the math, a virus that infects 10% of people and kills 0.1% of them can’t even begin to compare with a virus that infects 20-70% of people and kills 2-4% of them.
Granted, hopefully the actual death rate is lower. It may be as low as 0.5% when you factor in all the people who have mild symptoms and aren’t tested, but since its more contagious even the best case scenario means that it’ll kill at least 25x more people than the flu. Worst case scenario is it could kill well over 250 times more people than the flu.
Also there is another massive issue with the virus. It will overload hospitals, which could raise the death rates for both COVID-19 patients and people who need medical care for issues unrelated to the virus but can’t get it because all the hospital beds are occupied by COVID-19 patients.
For every 100 patients who get it I think about ~10% end up in the hospital. Around 5% end up on ventilators.
America only has 925k hospital beds total and 160k ventilators total. And most of those are already being used up for patients with other illnesses (we don’t have 925k empty hospital beds and 160k ventilators that aren’t being used, we have 925k and 160k total of each, the vast majority of which are currently being used for other sick patients).
If 20 million people have COVID at the same time, that means around 2 million people need hospital beds and 1 million people need ventilators. They won’t be able to get the ventilators, which means the death rate for the virus will go up.
Not only that, but what happens to all the people with emergency medical issues unrelated to COVID-19? You still have car accidents, strokes, heart attacks, accidents at work, etc. People will have these, go to the hospital but all the doctors, nurses, hospital beds and ventilators will be occupied by COVID-19 patients. People won’t be able to get the care they need for emergency medical issues unrelated to COVID-19.
So due to an overload of the hospitals, death rates from COVID-19 and death rates from other illnesses (strokes, accidents, heart attacks, etc) could also go up due to lack of proper medical care.
Among the elderly, the death rate is closer to 10%. If the virus infects a large enough share of the public (50-100%, that means 5-10% of the elderly will die. Globally, I assume the worst case scenario is about ~50 million deaths.
Also we have a vaccine for the flu, there is no COVID vaccine yet. There are also approved meds to help control the flu. THere are no meds to control COVID yet. There are experiments with protease inhibitors to control it, but there may not be a big enough supply of them yet.
A lot of people who say we are overreacting seem to think this is the peak of the illness. This isn’t the peak of the illness. If the Illness takes a year to run its course, we are basically on month 2. It’ll likely be a whole lot worse in summer.
TL;DR
[ul]
[li]COVID-19 is anywhere from 5-50x more deadly than the flu in patients who get it[/li]
[li]COVID-19 is more contagious than the flu, while the flu infects about 10% of Americans each year, COVID-19 may infect 20-70% of Americans. No idea what the rate could be overseas but I assume similar. [/li]
[li]We have a flu vaccine, we don’t have a COVID-19 vaccine[/li]
[li]We have pharmaceutical therapies for the flu, we have no therapies for COVID-19 yet other than experimental ones[/li]
[li]COVID-19 will overwhelm hospitals, meaning lots of people who need care for COVID-19 or other diseases will not be able to get the care they need[/li]
[li]COVID-19 will cause a lot of economic damage that will take years to recover from. The flu does not.[/li][/ul]
