Confirmed Cases: 6,293,308
Now, if you divide Deaths by the sum of (Deaths + Recovered) you get
(189,859)/(3,724,836) = 0.0509
which is a 5.1% death rate. Not too bad, you say?
(BTW, the world death rate is just about 5% using numbers from the same source above. Also, we use (Deaths+Recovered) because we don't know the outcome of the rest of the positive cases yet. If we used Deaths/Confirmed Cases as Johns Hopkins University uses (see https://coronavirus.jhu.edu/data/mortality) then the death rate (what JHU calls the fatality ratio) is about 3%. This is still 15 times the fatality ratio of seasonal influenza.)
Let us look at the same numbers for the seasonal influenza virus. Many people (Mr. Trump included) have said that the novel coronavirus is no worse than the flu, so let's look.
From the official CDC web site at:
(I used last flu season's data because all those numbers are complete and don't include any COVID-19 numbers.)
The case numbers and deaths from influenza are:
"CDC estimates that influenza was associated with more than 35.5 million illnesses, more than 16.5 million medical visits, 490,600 hospitalizations, and 34,200 deaths during the 2018–2019 influenza season. This burden was similar to the estimated burden during the 2012–2013 influenza season"
Unfortunately, the CDC doesn't tell us the Recovered cases, so we'll just use the medical visits as our denominator. So if you divide 34,200 deaths by 16.5 million medical visits you get
(34,200)/(16,500,000) = 0.00207
and rounding up, about 0.002
which is a death rate of 0.2%
So the COVID-19 death rate is about 25 TIMES the death rate of the seasonal influenza virus, at least in the United States. And we already have a vaccine for the influenza virus that millions of people take every year.
However, this doesn't say anything about how contagious COVID-19 is compared to the seasonal influenza virus. So lets look at that as well.
Here's a comparison of the novel coronavirus and the seasonal influenza virus from Johns Hopkins University. https://www.hopkinsmedicine.org/health/conditions-and-diseases/coronavirus/coronavirus-disease-2019-vs-the-flu
With respect to which virus is more contagious, here's what the CDC says
"While COVID-19 and flu viruses are thought to spread in similar ways, COVID-19 is more contagious among certain populations and age groups than flu. Also, COVID-19 has been observed to have more superspreading events than flu. This means the virus that causes COVID-19 can quickly and easily spread to a lot of people and result in continuous spreading among people as time progresses."
So, yeah, don't wear that mask. You'll be fine.
But maybe you should wear that mask - SO YOU DON'T KILL ANYONE ELSE, like your parents, your child's teacher, your neighbor, the checker at the grocery store, your spouse.
Look, I know that masks are uncomfortable. I don't like wearing a mask whenever I'm out of the house either. I don't like social distancing. I don't like not being comfortable going to restaurants or movies, or the theatre. But think about it this way; you're not wearing the mask so that YOU don't get sick, you're wearing the mask so that OTHER PEOPLE don't get sick. Until we have a vaccine the only way to stop this virus outbreak is to STOP THE SPREAD and the best way to do that on an individual level is to wear masks in public.
So please, listen to Dr. Fauci and wear the damn mask.
