You can unsubscribe at any time. The HHS Pandemic Influenza Plan has a goal of reducing the timeframe to make a pandemic flu vaccine from 20 weeks to 12 weeks, but accomplishing this is challenging. In 1918, the world was still engaged in World War I. According to the National Academy of Sciences. For example, four days after infection, the amount of 1918 virus found in the lung tissue of infected mice was 39,000 times higher than that produced by one of the comparison recombinant flu viruses.14. The 1918 influenza came to be known as “the Spanish flu,” although Spaniards called it “the French flu.” There was no good reason for naming the flu after the Spanish, though. He once again sought permission to excavate the gravesite from the village council — which he obtained — and he also hired locals to assist in the work. After the lethal second wave struck in late 1918, new cases dropped abruptly. This makes it like the H1N1 strain that caused the swine flu pandemic of 2009. The 1918 virus was extremely virulent. Planners have access to other materials as well. 2018; 108: 1469-1472. According to the National Academy of Sciences, during WWI the United States aggressively suppressed speech that could potentially dampen enthusiasm about the war. Firstly, 50 million is a conservative estimate for the number of dead – the figure could be many times that number. Pp. Pp.
), What made this flu different from all other flus was a dramatically higher fatality rate, plus the fact that while ordinary flus claimed casualties among the very young and the very old, this virus was especially deadly to young adults between the ages of 20 and 40.
101 No. Diagnostic tests for identifying influenza are now available and they are improving over time.  At the very least, there is little evidence that China as a whole was seriously affected by the flu compared to other countries in the world. Similarly, in Western Samoa 22% of the population of 38,000 died within two months. The tool is useful for planning purposes and for determining appropriate mitigations based on the severity of a pandemic. Hultin believed that within that preserved burial ground he might still find traces of the 1918 virus itself, frozen in time within the tissues of the villagers whose lives it had claimed. 6785-6790. Dr. Tumpey was required to take a prescribed prophylactic (preventative) daily dose of the influenza antiviral drug, oseltamivir, as an additional safety precaution to prevent him from becoming infected. Regarding genetic features of the NA that could explain the 1918 virus’ severity, the researchers were once again unable to find any single feature of the 1918 NA that contributed to the virus’ virulence.9 For example, in some modern influenza viruses, the loss of a glycosylation site in NA at amino acid 146 (in WSN/33) contributes to virulence and also results in the virus attacking the nervous system in mice. The plasmids then instructed the cells to reconstruct the RNA of the complete 1918 virus.  In the Dutch East Indies (now Indonesia), 1.5 million were assumed to have died among 30 million inhabitants. Movement and mobilization of troops placed large numbers of people in close contact and living spaces were overcrowded. But even as they fought an uphill battle against the virulent infection, tens of thousands of Kansas-trained troops would travel to Europe, where the pandemic erupted six to eight months later. The CDC states that the first confirmed cases in the United States were military personnel in the spring of 1918.  By 11 March 1918, the virus had reached Queens, New York.
Normally, the flu season lasts from October to March and those who succumb to it are predominantly young children, the weak and the elderly. 99. “Rescue of Influenza A Virus from Recombinant DNA” Journal of Virology.
They are credited with sequencing the genome of the 1918 virus. In the end, perhaps unsurprisingly, Hultin was unable to retrieve the 1918 virus from this initial attempt.
 With a world population of 1.8 to 1.9 billion, these estimates correspond to between 1 and 6 percent of the population. Why is Spanish Flu called Spanish Flu? , The first estimate of the Chinese death toll was made in 1991 by Patterson and Pyle, which estimated a toll of between 5 and 9 million. K. Taubenberger, Ann Reid, Amy Krafft et al. The specific criteria for each biosafety level are detailed in the CDC/NIH publication Biosafety in Microbiological and Biomedical Laboratories. One of the small things we can applaud ourselves for is that we have not given this outbreak a stigmatising name. Updating the accounts: global mortality of the 1918–1920 “Spanish” influenza pandemic. This pneumonia was itself caused by common upper respiratory-tract bacteria, which were able to get into the lungs via the damaged bronchial tubes of the victims.  Other U.S. cities including Detroit, Milwaukee, Kansas City, Minneapolis and St. Louis were hit particularly hard, with death rates higher than all of 1918. As Quora User said Spain was the only country in Europe that did not sensor reporting of influnza deaths.  For the rest of the population, the second wave was far more deadly; the most vulnerable people were those like the soldiers in the trenches – adults who were young and fit.. 76. No. ", "Pandemics Depress the Economy, Public Health Interventions Do Not: Evidence from the 1918 Flu", "Fetal shock or selection? He died six days later on September 26, 1918, and a sample of his lung tissue was collected and preserved for later study. A biometric fingerprint scan was required for access into the BSL-3E laboratory, and the virus storage freezers were only accessible via an iris scan of his eyes. ", In Finland, 20,000 died out of 210,000 infected. Hultin removed them, placed them in preserving fluid, and later shipped them separately to Taubenberger and his fellow researchers, including Dr. Ann Reid, at the Armed Forces Institute of Pathology.5 Ten days later, Hultin received a call from the scientists to confirm — to perhaps everyone’s collective astonishment — that positive 1918 virus genetic material had indeed been obtained from Lucy’s lung tissue. Photo credit: Johan Hultin. The noise generated from this activity apparently drew puzzled glances from fellow passengers and onlookers. The Spanish press, being those most likely to report on the virus and its spread, also gave the false impression at the time that the disease originated there. Particularly in Europe, where the war's toll was high, the flu may not have had a tremendous psychological impact or may have seemed an extension of the war's tragedies. In the trenches, natural selection was reversed. The claim: The 1918 flu pandemic became known as the “Spanish flu” because wartime censors minimized reports of the illness while the Spanish press did not. For example, to prevent mix-ups and cross-contamination, work on the 1918 virus could not take place alongside work on other influenza viruses.
As Slate tells it, “Many sufferers came down with severe nosebleeds — some spewed blood out of their nostrils with such force that nurses had to duck to avoid the flow. Vol. Today, Dr. Tumpey is the branch chief of the Immunology and Pathogenesis Branch in CDC’s Influenza Division.  One group of researchers recovered the virus from the bodies of frozen victims and transfected animals with it.  After the signing of the Treaty of Brest-Litovsk (March 1918), Germany started releasing Russian prisoners of war, who then brought the disease to their country. This considerably enhanced the ability of the global flu surveillance community to track spread of the virus.3. Such evolution of influenza is a common occurrence: there is a tendency for pathogenic viruses to become less lethal with time, as the hosts of more dangerous strains tend to die out. The 1918 H1N1 flu pandemic, sometimes referred to as the “Spanish flu,” killed an estimated 50 million people worldwide, including an estimated 675,000 people in the United States. Med. A picture of Johan Hultin excavating a body from the Brevig Mission burial ground.  This is unusual since influenza is typically most deadly to weak individuals, such as infants under age two, adults over age 70, and the immunocompromised. This answer was taken from BBC History Revealed magazine, We recently interviewed Laura Spinney about pandemics for the HistoryExtra podcast. Listen to the most important stories of the day. Australia also managed to avoid the first two waves with a quarantine. Based on the 1918 virus’ sequence data Taubenberger assembled in 1997, he and his fellow researchers initially claimed that the 1918 virus was a novel influenza A (H1N1) virus that belonged to a subgroup of viruses that came from humans and pigs, as opposed to birds.6 However, there was still much to learn about the virus. It even passed legislation making it a criminal offense punishable by 20 years in prison to "utter, print, write or publish any disloyal, profane, scurrilous, or abusive language about the government of the United States."  There was also great variation within continents, with three times higher mortality in Hungary and Spain compared to Denmark, two to three times higher chance of death in Sub-Saharan Africa compared to North Africa, and possibly up to ten times higher rates between the extremes of Asia. The authors noted that contemporary avian influenza virus strains are very different from the 1918 pandemic virus, and unfortunately older avian strains from around the time of the 1918 pandemic were not available for study.  In contrast, Japan and Taiwan had reported a mortality rate from influenza around 0.45% and 0.69% respectively, higher than the mortality rate collected from data in Chinese port cities, such as Hong Kong (0.25%), Canton (0.32%), and Shanghai. Hospitals and doctors’ offices would struggle to meet demand from the number of patients requiring care. sfn error: multiple targets (2×): CITEREFTaubenbergerMorens2006 (, sfn error: multiple targets (2×): CITEREFBarry2004 (, sfn error: multiple targets (3×): CITEREFSpinney2018 (, sfn error: multiple targets (2×): CITEREFPattersonPyle1991 (, David Arnold, "Dearth and the Modern Empire: The 1918–19 Influenza Epidemic in India,". A 2009 study in Influenza and Other Respiratory Viruses based on data from fourteen European countries estimated a total of 2.64 million excess deaths in Europe attributable to the Spanish flu during the major 1918–1919 phase of the pandemic, in line with the three prior studies from 1991, 2002, and 2006 that calculated a European death toll of between 2 million and 2.3 million. Historical research report from University of Indonesia, School of History, as reported in Emmy Fitri. Modern flu vaccines work by targeting an influenza virus’ unique HA (a fact that virologist Dr. Peter Palese, featured later in this article, helped pioneer). Hultin saw that the small crosses that previously covered the site were missing, so Hultin built two large crosses (shown above) within the woodshop of a local school to mark the gravesite.
