Steepen the Curve

Title text: 1. Flatten the curve. 2. Steepen the curve. 3. Hang out.

Explanation

This explanation may be incomplete or incorrect: Created by a STEEPENED FLATTENED CURVE. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon. If you can address this issue, please edit the page! Thanks.

In 2020, the main public concern rapidly became that deaths from COVID-19 were escalating. All kinds of political, civic and personal efforts were put towards doing things that would cause the 'curve' (the graph of cumulative deaths, or deaths per period) to flatten and not rise as rapidly as it was feared it would do, unchecked. The graphic drawn in black depicts this statistic — though it is not clear (without proper units or values on either axis) if this is a cumulative one or the initial 'rate' graph for before initial lockdowns started to reduce the initial trajectory for a time.

In 2021, the same issues exist (with second or even third 'waves' of resurgence affecting some populations) but now we have a handful of vaccines available. The red overlay intends to update the 'original' graphic to portray the curve of vaccines provided (again, it could easily be either cummulative or rate-wise). This year, the line remains the same but the year, the thing labelled as being represented and the hoped-for outcome are changed accordingly.

Note that, in both cases, there would be an upper limit on the cummulative value, but the ceiling must be well beyond the upper (and timewise) limits of this graph. If this is a rate-graph, it would show a peak and subsequent decline at the same point in time where a cumulative graph would show an inflection in its gradient, but neither are visible here.

My first transcript. Please improve on it so I can see how dumb I am at it. — The 𝗦𝗾𝗿𝘁-𝟭 ^{talk stalk} 03:29, 9 January 2021 (UTC)

Nice first try. I only added a bit more detail to the explanation of the drawing. --Kynde (talk) 15:42, 9 January 2021 (UTC)

Was the curve to be flattened always deaths? I thought it was covid cases in general, but I never really thought about it in depth. Captain Video (talk) 04:10, 9 January 2021 (UTC)

Well, given the tight ratio (in the early days, anything done at the treatment end that further decreased the deaths per cases was a bonus to all other efforts concentrating on keeping treatable cases down in the first place, but conversely added to any overloading of the respective healthcare system with a degree of extended aftercare, etc) I think it was effectively equivalent. But I never really considered it in so much depth (or width, or deadth) at the time either. It's clear this is an (unspecific) snapshot of the initial surge. 141.101.99.49 05:01, 9 January 2021 (UTC)

Death count is just convenient to measure (as opposed to case count or recovery without relapse count). bubblegum-talk|contribs 05:05, 9 January 2021 (UTC)

I remember the discussion in March and April 2020 to "flatten the curve" was primarily to flatten the rate of contagion (and by extension the rate illness) in order to preserve medical resources. There was never any notion that we could stop people from dying, only that by flattening the curve we could postpone the consequences of the disease, including postponing the deaths. We also have gained knowledge about what treatments are most effective, and that helps a lot. Because of Operation Warpspeed and scientific advances we now have vaccines in an unprecedented short period of time, so that if we can continue to keep the contagion rate low enough we will eventually have enough people vaccinated that the number of disease cases (and deaths) will drop off dramatically. Hang in there a little longer and we will make it. Rtanenbaum (talk) 15:56, 9 January 2021 (UTC)

I always heard about flattening the curve in context of number of cases requiring hospitalization. And the idea was specifically to keep the curve UNDER the line which represented capacity of hospitals to handle those cases. -- Hkmaly (talk) 06:43, 10 January 2021 (UTC)

That sounds most correct to me: the effort was to flatten the curve of infections to prevent hospital (specifically) and other medical (generally) capacity from being overwhelmed. We'd do this by reducing the rate of infections through sanitary and safety measures. There was a lot of talk of trying to get the basic reproduction number R0 as close to 1 as possible to limit that exponential growth curve we're all so familiar with now. Transmissibility of the disease is not the same as mortality, though of course they are correlated. Preventing deaths was intended as a happy bonus effect of preventing the medical system from collapsing. I think it's worth rewording the explanation, even though the comic does use a chart of deaths rather than infections - they look very similar under a functioning medical system. --172.69.42.92 07:11, 10 January 2021 (UTC)

Note that R₀, the "Basic Reproduction Number is, at its strictest, not alterable in any way at all (although it may be reassessed). It is the measure of effectiveness (but not speed, as it isn't defined in terms of time) of viral transfer in a parricular population, given that they are all unpreinfected (save for the seeds it spreads from), unvaccinated and otherwise precautionless/naïve about the 'threat'. You can lower the instantaneous/effective R (mostly called "the R-value", probably to appease those similarly pedantic, but also R_t or R_e), as a measure of how you are suppressing it, but R₀ is (per situation or grouping concerned) not changeable after the fact. Except by recalculating with new historical insights that don't change the current reality, just perhaps help explain how we got here. 141.101.98.208 01:46, 11 January 2021 (UTC)

Explainxkcd is one of my favorite things in the world.. this is my first comment. I'm hesitant to make a major edit without discussion, but I think the statement about 2nd and 3rd waves could be much, much stronger to the point of this being a dangerous message to be sending right now. About three days ago Science published a piece "Viral mutations may cause another ‘very, very bad’ COVID-19 wave, scientists warn , read the link but contains take your pick of alarming quotes, with a conclusion of "It’s dispiriting to feel like the world is back where it was in early 2020, says epidemiologist William Hanage of the Harvard T.H. Chan School of Public Health. “But we have to stop this virus. … Fatalism is not a nonpharmaceutical intervention.” I think this comic works against the conclusions of what seems to be a consensus of experts and that that is worth saying.. many people read xkcd, and the curve omits a reasonably likely scenario.. that we begin to see what the death rate looks like when a fresh shock to transmission dynamics rate hits multiple maxed out regions that are already beyond their maximum hospital capacity. But I'm a bit unsure of the etiquette, if one exists, for saying that a comic works against the public interest. Seems like a pretty strong stance, right? The analysis of this strain is moving very quickly.. that Science paper is from three days ago, likely before the comic was published. Request help in non jerky way to express this (if at all) in the explanation. Poisedleft (talk) 08:42, 10 January 2021 (UTC)

"The graphic drawn in black depicts exponential growth in number of deaths — though it is not clear (without proper units or values on either axis) if this is a cumulative count of deaths or the rate of deaths per day." For exponential growth both cumulative counts and deaths per day grow exponentially (d/dx {exp(x)} = exp(x)) The explanation does not quite reflect this, it reads as "either/or" rather than "both".162.158.79.175 19:49, 11 January 2021 (UTC)

I gave it a tweak. (It already suffered from multiple authors, one more can't hurt, unless someone wants to do a complete rewrite just in time for it getting a Next link... ;) ) 141.101.98.208 23:45, 11 January 2021 (UTC)

Is the 3-step Alt Text a reference to something? I can understand that the "Hang out" at the end refers to being able to socialize in the same way that we did in the Pre-Pandemic Times, but the punchy formatting suggests to me that it's a spoof of something else, in the vein of "Step One, [random thing]; Step Two, ?????; Step Three, Profit!" 172.69.170.142 19:57, 11 January 2021 (UTC)MeZimm
