With the United states hitting the grim milestone of nearly 550,000 deaths indigenous COVID-19 and increasing public acknowledgment that thousands of thousands the those deaths may have been preventable, we may see renewed referrals to the devastating toll the the 1918–19 influenza epidemic. These comparisons will certainly be more insightful if we understand whose deaths to be (and were not) contained in the counting of victims throughout the “Spanish flu.”
The COVID-19 pandemic has actually demonstrated the value of exact statistics for setting health policy and also educating the public around likely outcomes. Because the COVID-19 pandemic came to public attention, examples from the 1918 influenza have actually been invoked to describe how to flatten the curve through social distancing, the efficacy that masks, and also the advisability of institution closings. In ~ the start of the present pandemic, guess of numerous thousands of united state deaths seemed to prompt wellness officials as well as segments of the public to take the disease more seriously and also understand the need for significant mitigation measures.

These predictions illustrate a primary challenge of public health policy as well as messaging, i m sorry is the should encourage civilization to acknowledge a threat without generating despair around potential outcomes the may subsequently lead to denial or inaction. The graphics warning from a placard displayed on streetcars throughout the 1918 epidemic in Philadelphia, stating simply, “Spit spreads Death,” illustrates exactly how public health messaging occasionally requires blunt statements that an individual behaviors must adjust to prevent raised mortality.
In illustration these analogies from previous epidemics, however, we additionally need to identify that among the most widely reported facts from 1918–19, the death of 675,000 Americans, is based on limited, inconsistent, and even dangerous reports. For health policy makers in 2021, understanding how deaths to be counted in this previously epidemic should administer a useful allude of referral for educating the public around the increasing toll of COVID-19, through the goal of convincing world to take actions needed come gain manage of the disease.
Unpacking The “Spanish Flu” Mortality Numbers
Any mortality comparisons between these two pandemics in the unified States, 2020 and 1918, need to differentiate between totals and also rates. The current US population, a little much more than 330 million, is an ext than three times bigger than the populace in 1918, approximated at 105 million. The 675,000 deaths attributed to the influenza epidemic comprised 0.64 percent of the total population, a little more than 6 in every thousand people. By contrast, the more than 500,000 deaths attributed come COVID-19 do up about 0.15 percent of the total population, or in between one and also two in every thousands people. If COVID-19 resulted in deaths at the same price as the 1918 epidemic, the complete would method two million. Also the disturbing projections of more than to 600,000 deaths through July 1, 2021, would still remain below the prices recorded in the earlier epidemic.
It is vital to identify that us don’t know precisely how many human being died of “Spanish flu.” measure influenza deaths is facility because this disease often contributes come deaths attributed to other main causes. The Centers for condition Control and Prevention Pneumonia and Influenza Mortality surveillance combines two causes into one reporting category. Many reports during the “Spanish flu” suspect this practice by combine influenza and pneumonia deaths together, thus recognizing the the epidemic produced an ext deaths than were simply attributed come influenza. We see a comparable pattern today, together the actual count of pandemic deaths should incorporate far much more than those attributed specifically to COVID-19.
While we most typically refer come it as the 1918 influenza, the estimates of death from the pandemic actually cover the last 4 months that 1918 and also the an initial six months of 1919. Analysis of monthly fatality totals because that 1918 and also 1919 in the “registration states” (defined below) shows that the striking increases in all deaths were due nearly entirely to boosts in pneumonia and influenza deaths (exhibit 1). When the biggest increases emerged in loss 1918, the total variety of deaths stayed high for number of months, as roughly one-quarter the epidemic deaths actually developed in 1919.
Exhibit 1: Deaths, it is registered states, 1918–19
Sources: 1918 Mortality Statistics and also 1919 Mortality Statistics.
Extrapolating 1918–19 Influenza Deaths from A Disproportionately White, city Sample
We also need to identify that the estimated 675,000 deaths is based upon a partial, and also not truly representative, sample the the population. The calculation of this full was defined by the eminent eco-friendly historian, Alfred Crosby, in American’s forget Epidemic. As crosby noted, the united state Census Mortality Statistics walk not incorporate the entire United States. The 1918 Mortality Statistics had 31 states and also the ar of Columbia, which accounting for simply three-quarters of the complete population. Three more states were included to the 1919 Mortality Statistics, yet the states covered quiet represented much less than four-fifths of the total population. Once Crosby calculation the fatality toll indigenous the influenza epidemic, he counted pneumonia and also influenza deaths in the 1919 “registration states”—approximately 549,000”—and climate simply included another 25 percent, to create the “best estimate” that 675,000 deaths. This full has been repeated in numerous scholarly articles and public reports referencing this historical event.
This mediate does no take into consideration, however, the reality that the registration states were not extensively representative. Every state in the northeast, from Pennsylvania to Maine, to be included among the registration states, along with most says in the mid-Atlantic, upper Midwest, and Pacific shore (exhibit 2). Yet the 1918 it is registered states consisted of a reasonably small representation from other regions: four states indigenous the southeast, three states from the hill west, two says from the main plains, and no says from the southwest.
Exhibit 2: us Registration States, 1918–1919
Sources: 1918 Mortality Statistics and also 1919 Mortality Statistics.
The registration says excluded roughly one-half that the afri American population, as reported by the united state Census in the annual Statistical Abstract. Afri Americans made up 10 percent of the us population, yet just 6 percent the the population of the it is registered states, compared to much more than 20 percent that the populace in the non-registration states. Alabama, Georgia, Mississippi, and Texas, with much more than 4 million african American citizens cumulatively, were excluded native registration says in 1918 and 1919. Offered the differential influence of the 1918 epidemic on african American populations, together examined by historian Vanessa Northington Gamble, any type of discussion that totals should take into factor to consider how this populace was mainly excluded from the statistics record.
The registration states also did not stand for the density of the united state population. According to the 1910 census, 46 percent, or just listed below one-half, that Americans resided in “urban” areas, i m sorry meant populaces of 2,500 or more. Through contrast, the population in registration says was 55 percent urban, mirroring the densely occupied northeast and large cities in the Midwest. In non-registration states, however, only 25 percent the the populace was urban, together these states had the more sparsely lived in plains, mountains, and also southwest.
If we usage the registration states to calculate complete epidemic deaths, us must consider the level to i beg your pardon data was skewed towards a an ext urban and less racially varied population. Recognizing this fact may not readjust the total variety of deaths, but it have to be acknowledged if we usage this data to do comparisons through the COVID-19 pandemic.
The timing Of Deaths In 1918–19 versus 2020–21 and also What it Says about Our an answer To COVID-19
The timing of deaths might be the most crucial comparison for understanding parallels and also contrasts with the existing epidemic. In October 1918, an approximated 200,000 Americans passed away from pneumonia and also influenza. This worst month the the epidemic videotaped an average of more than 6,000 influenza and pneumonia deaths each day throughout the united States. As soon as we to compare 2020 with 1918, we need to acknowledge that this remarkable day-to-day toll a century ago occurred in a population one-third the the us today.
In Pennsylvania, much more than 30,000 people died native the epidemic in October 1918. In new Jersey, one in every 250 citizens passed away of pneumonia or influenza in simply this one month. 6 midwestern states, Ohio, Indiana, Illinois, Missouri, Michigan, and Wisconsin, totaled more than 30,000 deaths in October 1918, even with rates lower than states situated to the east. California recorded practically 5,000 deaths in October, and also a slightly higher total in November, as the epidemic peaked later in the west regions. In new York City, much more than 16,000 civilization died from influenza and pneumonia in October 1918, an mean of an ext than 500 deaths a day just in this one city.
Yet, the time of deaths in 1918 important highlights the impressive shortcomings that the US response to COVID-19. In October 1918, this suddenly escalation in deaths emerged within main of the an initial cases and also deaths. Federal government leaders, wellness officials, and the publicly were taking care of the surge in cases and deaths also as lock implemented new health measures such together restricting publicly meetings, close up door schools, mandating masks, and encouraging much better hygiene. They were overwhelmed by the unexpected epidemic and failed come contain the sudden surge in deaths.
By the time public health and wellness measures to be implemented, the spread of the an illness was already slowing and also mortality rates were falling. When new waves of condition appeared in late 1918 and early 1919, public health and wellness officials moved conveniently to renew these measures, which were, in many cases, not required as the an illness did not go back to the very same level of severity it was observed in the worst weeks of the epidemic.
In 2020, by contrast, federal, state, and also local officials and also the whole public had months to understand the infection of the coronavirus, evaluate health and wellness measures, and take measures to safeguard their communities. Predictions of high fatality totals were reported however often dismissed or disregarded. We have accessibility to an extraordinary quantity of data around COVID-19 because that the unified States and also the world, and granular information about testing, cases, epidemic rates, hospitalizations, and deaths in ~ the national, state, regional, and even local level. We have known what is happening, and likely outcomes, and yet so many world have refused to make the changes in actions necessary to manage the ongoing spread of this disease, particularly among the most delicate populations.

The reality that deaths surged at the finish of 2020, ripe months after the pandemic got to the joined States, with the highest possible daily death tolls in beforehand January 2021, is possibly the most discouraging comparison come the historic record. We ignored the lessons of 1918, and also then us disregarded warnings authorize in the very first months of this pandemic. We will never know how plenty of lives could have been saved if we had taken this threat more seriously. We room paying a destructive price currently for this failure of policy and practice.
