As countries around the world pay rapt attention to the rising number of confirmed coronavirus cases and deaths from COVID-19, some confusion about the mathematics of it all keep floating around.
I've seen countless comments from people who say things like:
"The virus has only killed 20,000 people. The seasonal flu kills 60,000 people each year and we don't shut the country down for that!"
"Far more Americans die of flu/cancer/heart disease/etc. than will die from COVID-19 this year. Why aren't we shutting down the economy for those things?"
The idea that the coronavirus isn't markedly different or worse than the seasonal flu got an early hold in some people's consciousness when the virus first emerged. Part of the problem is that the virality and mortality of the virus hasn't been totally clear. Even Dr. Fauci and colleagues wrote an editorial published February 28 in the New England Journal of Medicine stating that the coronavirus death rates "may ultimately be more akin to those of a severe seasonal influenza (which has a case fatality rate of approximately 0.1%) or a pandemic influenza."
However, with a novel virus, things change quickly and experts' knowledge and understanding change along with it. As we saw numbers begin to emerge from around the world, it became clear that this virus is more contagious and far deadlier than the seasonal flu. Dr. Fauci stated in an interview with Trevor Noah on March 26 that the coronavirus was actually at least twice as contagious and ten times as deadly as the seasonal flu. Though death rates vary widely by country so far, and we won't have a clear picture of that rate for quite some time, it's clear that this isn't your average flu.
Additionally, normal flu seasons vary in severity, but the flu is largely a known quantity. We know there will be flu strains, and epidemiologists construct a vaccine each year based on their most informed guess as to which strains will be circulating the most. So we have vaccines and we have treatments to lessen flu severity, such as Tamiflu. And since flu-related deaths happen fairly evenly throughout flu season, our hospital system doesn't get overwhelmed by them.
Let's hold that thought about overwhelmed hospitals while we look at the other comment about various causes of death.
Yes, based on the numbers of deaths we've seen so far, more Americans die of things other than coronavirus each year. But there are some big "buts" here. Most of those causes of death are not communicable diseases. If shutting down the country for a period of time was guaranteed to save people's lives from heart disease or cancer, I'm sure we'd do that. But we are already doing what we can to try to reduce deaths from things like heart disease, cancer, car accidents, and the seasonal flu.
A viral pandemic gone unchecked is an entirely different beast. We have been watching both the case numbers and the death numbers rise dramatically, even after enacting social distancing and locking down the country.
This chart shows a daily visualization of the increase in COVID-19 deaths in the U.S. compared to the average daily deaths from various causes from March 1 to April 18, 2020. GIve it 10 seconds or so, since the virus deaths start off slow, but then really start really taking off after March 20.
By April 8, you can see that the virus's daily death toll overtakes every other cause of death in America.
This is called exponential growth. I've seen people say that coronavirus has killed 20,000 Americans in four months, making it sound like it was an average of 5,000 per month, but that's not how this works. In January, we had no deaths. In February, just a few. By March 26, we had 1,000. Less than 3 weeks later, we're at around 22,000. That's what we mean by exponential growth. No other cause of death does that.
And again, this is with mitigation measures in place for the past month. Imagine what it would look like if we'd kept up business as usual during the past few weeks and let the virus spread unchecked. This kind of exponential growth in deaths is exactly why nations around the globe have shut down businesses and enacted social distancing guidelines.
This is not the seasonal flu. We don't have a vaccine for this. We don't have a cure for this. We don't even have a sure-fire, reliable treatment for this.
The problem is that people see that numbers are not exploding as much as some models indicated they would and think "Oh, this has all been overblown!" They're only seeing some overwhelmed hospitals in select areas and think that means all of the widespread preparations and shutdowns weren't necessary. But that notion ignores the fact that the initial models provided an estimate for what would happen if we didn't shut the country down, which was an absolutely catastrophic outcome with millions of deaths. Without these "extreme" measures, the death toll would be far higher, and more hospitals would be out of beds and ventilators. And it's hard to predict beforehand where a big outbreak might spring up.
And we're not even close to out of the woods yet. Our case and death numbers are still climbing, though experts indicate that we may be at a peak where we might plateau for a while.
But the bottom line is that this virus is not like something we've seen before. The death numbers we've seen so far can't be compared to anything else. And we need to keep on doing what we're doing to keep those exponential numbers under control.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
