Pp. The recruits were sent to… Camp Funston. Pictured, an emergency hospital for flu patients at Camp Funston. In the end, perhaps unsurprisingly, Hultin was unable to retrieve the 1918 virus from this initial attempt. That person was trained microbiologist Dr. Terrence Tumpey, who was approved for the project by then CDC director, Dr. Julie Gerberding. Influenza pandemic of 1918–19, the most severe influenza outbreak of the 20th century and among the most devastating pandemics in human history. And smaller flu outbreaks were reported in France before that, as far back as 1916. This includes (but isn’t limited to) use of a powered air purifying respirator (PAPR), double gloves, suit, and working within a Class II biosafety cabinet (BSC). Barbara Jester et al. History of 1918 Flu Pandemic. All that traveling took several weeks. October 2005. Sequencing results suggested that the ancestor of the 1918 virus infected humans sometime between 1900 and 1915. The World Health Organization (WHO) has published instructions for countries to use in developing their own national pandemic plans, as well as a checklist for pandemic influenza risk and impact management.3. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919. Was She? The amount of 1918 flu virus was measured in the cells at 12, 16 and 24 hours post infection and these results were compared to those produced by recombinant viruses with a combination of genes from the 1918 virus mixed with genes from contemporary human seasonal flu viruses. The authors also noted that the 1918 virus’ HA1 had only four glycosylation sites, which is different from modern human HA’s which have accumulated up to five additional glycosylation sites through the process of antigenic drift. A small ocean-side village in Alaska called Brevig Mission would become both testament to this deadly legacy as well as crucial to the 1918 virus’ eventual discovery. Many people are familiar with the concept of DNA, which is dual-stranded and determines the fundamental genetic characteristics of nearly all living things. Then it would have mutated again, becoming the Spanish flu strand. To reduce risk to colleagues and the public, he was required to work on the virus alone and only after hours when fellow colleagues had exited the laboratories for the day and gone home. The work would be performed using stringent biosafety and biosecurity precautions and facilities, including what’s known as Biosecurity Level 3 (BSL-3) practices and facilities with enhancements. The grave was frozen in permafrost and left untouched until 1951. So China -who favored the Allies- sent 140,000 laborers to Europe. Senior government officials decided on CDC headquarters in Atlanta as the location of the reconstruction. Initial Genetic Characterization of the 1998 “Spanish’ Influenza Virus. “Molecular Basis for High Virulence of Hong Kong H5N1 Influenza A Viruses” Science. 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. These subsequent pandemics were less severe and caused considerably lower mortality rates than the 1918 pandemic.2,3,4 The 1957 H2N2 pandemic and the 1968 H3N2 pandemic each resulted in an estimated 1 million global deaths, while the 2009 H1N1 pandemic resulted in fewer than 0.3 million deaths in its first year.3,4 This perhaps begs the question of whether a high severity pandemic on the scale of 1918 could occur in modern times. Also of note, the authors did not see any genetic changes in the 1918 virus’ HA that would explain its exceptional virulence. How the Ancients Described Him, View 128 Ancient Coins That Show Cleopatra’s Face, What Julius Caesar and 14 Other Famous Romans Looked Like. For example, penicillin was not discovered until 1928. The author noted that NA is also targeted by the immune system, and that antibodies against NA do not prevent infection, but they do significantly limit the ability of the virus to spread. In 1918, the world was still engaged in World War I. While medically serious and … And nowadays, the U.S. origin theory is the one with the most supporters in the scientific world. Sometimes the blue tint became so pronounced that it was difficult to determine a … 12. Flu vaccines are now produced and updated yearly, and yearly vaccination is recommended for everyone 6 months of age and older. 1746-2751. The local doctor, Loring Miner, was alarmed enough to report the situation to the Public Health Services. Why Spanish flu was so fatal, especially to people in the prime of their lives, is what scientists are striving to understand, as TIME reported in the wake of Hong Kong’s 1997 avian flu … Its origins are unknown to this day. Businesses and schools would struggle to function, and even basic services like trash pickup and waste removal could be impacted. Furthermore, the 1918 virus’ NA obtained from Lucy suggested that it is very similar to the ancestor of all subsequent swine and human isolates.9. Her Family Tree, Spanish Flu: What Worked Against It, and What Stopped It. 2018; 108: 1469-1472. Health services were limited, and up to 30% of U.S. physicians were deployed to military service.3. The 1918 virus replicates quickly and causes severe disease in the lung tissues of mice. Laboratory studies on the reconstructed 1918 virus began in August 2005. Due to the mobility and expansion of human populations, even once exotic pathogens, like Ebola, which previously affected only people living in remote villages of the African jungle, now have managed to find their way into urban areas, causing large outbreaks. So here again, Hultin’s work proved invaluable. However, one well-documented effect of the 1918 virus was rapid and severe lung damage. 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. We’ve all heard of the devastation of the 1918 Spanish flu, a lethal pandemic that killed 50 million people worldwide. “Characterization of the 1918 influenza virus polymerase genes” Nature. They sustain there was a flu outbreak in the Chinese villages along the Great Wall in late 1917. “Recombination in the Hemagglutinin Gene of the 1918 “Spanish Flu” Science. The next step was to study it and unlock its deadly secrets. 1840-1842, Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases (NCIRD), The Deadliest Flu: The Complete Story of the Discovery and Reconstruction of the 1918 Pandemic Virus, Allocating & Targeting Pandemic Influenza Vaccine, Vaccination of Tier 1 at All Pandemic Severities, Implementation of this Guidance during a Future Pandemic, Vaccination Tier 2 through 5 by Pandemic Severity, Next Steps for the U.S. Government, States, and Communities, Regulations and Laws That May Apply During a Pandemic, Surveillance, Epidemiology and Laboratory, Vaccine and Other Medical Countermeasures, Healthcare System Preparedness and Response, PanVax Tool for Pandemic Vaccination Planning, U.S. Department of Health & Human Services. Photo credit: Johan Hultin. Palese has many accomplishments, including creating the first genetic maps of influenza A, B, and C viruses, as well as defining the mechanism used by the majority of current influenza antiviral drugs. 10717-10723, Ann Reid et al. Read next: What Did The Most Famous Romans Look Like? Historian John Barry has tracked a previous severe outbreak of influenza in Kansas. No. For reference, there are four biosafety levels that correspond to the degree of risk posed by research, with 1 posing the least risk and 4 posing the greatest risk. And that they were not connected with the pandemic. Am J Epidemiol. Photo credit: Wikipedia (https://en.wikipedia.org/wiki/Peter_Palese). He sent a playful, Neil Armstrong-inspired email later that day to colleagues and collaborators, which simply said “That’s one small step for man, one giant leap for mankind.” Everyone then knew what had been accomplished. The trenches in northern France were bombarded with mustard gas. For example, all personnel must wear a powered air purifying respirator (PAPR), double gloves, scrubs, shoe covers and a surgical gown. Within a few days, what doctors had initially called a "three day fever" had progressed to a high fever and included a cough and a headache. Scientists that study the evolution of viruses also think the so-called Spanish flu originated in the U.S. Due to its genetic make-up, they argue, it probably originated in the Western Hemisphere, and probably in North America. If it did, experts believe it could result in a pandemic with severity comparable to the 1918 pandemic. This is a picture of an influenza virus. 1918. It said soldiers were dying of “purulent bronchitis” in southern England and northern France. CDC in Atlanta is one of WHO’s six Collaborating Centers for Reference and Research on Influenza (joining others in Australia, China, Japan and the United Kingdom). Nov 1999. The outbreak was caused by influenza type A subtype H1N1 virus. In the U.S., the Spanish flu was first identified in military personnel when 100 cases were reported at Camp Funston in Fort Riley, Kansas in Spring 1918, according to the CDC. When the flu reached Spain in May 1918, it had been circulating in neighboring France and in the U.S. for at least two months. Am J Public Health. It wouldn’t be until 46 years later, in 1997, that Hultin would have another opportunity to pursue the 1918 virus. “Existing antivirals are effective against influenza viruses with genes from the 1918 pandemic virus.” PNAS. Hemagglutinin (HA) is a surface protein of the virus that plays a role in allowing an influenza virus to enter and infect a healthy cell. This two-year fellowship in CDC’s Influenza Division would mark the beginning of Dr. Tumpey’s career at CDC. https://www.sfgate.com/magazine/article/The-Virus-detective-Dr-John-Hultin-has-found-2872017.php. In that way, the 1918 virus was special – a uniquely deadly product of nature, evolution and the intermingling of people and animals. The 1918 flu was first observed in Europe, America and parts of … To receive email updates about this page, enter your email address: Find information on coronavirus disease 2019 (COVID-19). However, the genome of an influenza virus consists of single-stranded RNA instead. PNAS. Vol. The score provided by the IRAT answers two questions: 1) What is the risk that a virus that is novel in humans could result in sustained human to human transmission? Cleopatra’s Ethnicity: Black, White, or Mixed? The HA … A CDC laboratory scientist “candles” a chicken egg to show the chicken embryo within. 2) the Chinese allies disembarked in western Canada. Recently, new “rapid molecular assays” have become available that are timely and much more accurate than RIDTs. Ann Reid et al. Vol 73. In 1951, Hultin successfully obtained permission from the village elders to excavate the Brevig Mission burial site. Barbara Jester et al. Photo credit: C. Goldsmith - Public Health Image Library #11098. It killed between 50 and 100 million people. “Pathogenicity and immunogenicity of influenza viruses with genes from the 1918 pandemic virus. The first recorded case -that it is certain was- of Spanish flu comes from a military training camp in Kansas: Camp Funston. Glycosylation sites are believed to be necessary for the function of influenza viruses, and the inclusion of additional glycosylation sites is believed to be an adaptation of the virus to human hosts. For example, to prevent mix-ups and cross-contamination, work on the 1918 virus could not take place alongside work on other influenza viruses. Furthermore, the 1918 virus was highly lethal in the mice. So, thanks to the mutagenic gas, the pig virus would have mutated and jumped to humans. Furthermore, there were pigs and other farm animals at the camp in Etaples. After all, this flu was the deadliest pandemic in history. The cause of death listed in the report was influenza. He died six days later on September 26, 1918, and a sample of his lung tissue was collected and preserved for later study. So they nicknamed it “Spanish flu.”. Note: using one’s mouth to draw virus into a pipette is not considered a safe laboratory practice today. Following the 1918 pandemic, generations of scientists and public health experts were left with only the epidemiological evidence of the 1918 pandemic virus’ lethality and the deleterious impact it had on global populations. In 2008, CDC established the International Reagent Resource (IRR), which provides reagents to laboratories around the world to identify seasonal influenza A and B viruses, as well as novel influenza A viruses. 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. His wife’s garden shears, which Hultin borrowed to conduct the excavation, are shown in the center of the picture. Many researchers think those episodes were not seasonal influenza. 9679-9682, Darwyn Kobasa et al. Español. April 1918. The decision to reconstruct the deadliest pandemic flu virus of the 20th century was made with considerable care and attention to safety. 12462-12470, Jeffery K. Taubenberger et al. Similar to the experiments involving mice, the 1918 virus quickly multiplied and spread within the human lung cells. What did Cleopatra Look Like? The outbreak began in 1918, during the final months of World War I, and historians now believe that the conflict may have been partly responsible for spreading the virus. Vol. Generally, it has taken about 20 weeks to select and manufacture a new vaccine. If a severe pandemic, such as occurred in 1918 happened today, it would still likely overwhelm health care infrastructure, both in the United States and across the world. Since 1918, the world has experienced three additional pandemics, in 1957, 1968, and most recently in 2009. Later, at the order of the local government, a mass grave site marked only by small white crosses was created on a hill beside the village – a grim monument to a community all but erased from existence. The cause of the 1918 Spanish Flu Pandemic was unknown at the time, many believed it was caused by the use of chemical warfare and poison gas together with the filth of the lice and rat infested trenches. The majority of counties that report to the WHO still do not have a national pandemic plan, and critical and clinical care capacity, especially in low income countries, continues to be inadequate to the demands of a severe pandemic.3 In 2005, milestones were created in the revised International Health Regulations (IHR) for countries to improve their response capacity for public health emergencies, but in 2016, only one-third of countries were in compliance.3. Once Dr. Palese and his colleagues at Mount Sinai completed creation of the plasmids, they were shipped to CDC so the official process of reconstruction could begin. These HA surface proteins allow an influenza virus to enter and infect a healthy respiratory tract cell. The military camp housed 50,000 soldiers that were trained there before being sent to Europe. When considering the potential for a modern era high severity pandemic, it is important; however, to reflect on the considerable medical, scientific and societal advancements that have occurred since 1918, while recognizing that there are a number of ways that global preparations for the next pandemic still warrant improvement. And scientists believe the Spanish flu virus circulated in either pigs or birds before it infected humans. 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 1918 outbreak has been called the Spanish flu because Spain, which remained neutral during World War I, was the first country to publicly report cases of the disease. Another set of experiments was conducted to better understand the possible avian origins of the 1918 virus. In the paper, the authors described their effort to sequence (i.e., characterize) the 1918 virus’s hemagglutinin “HA” gene. The best defense against the flu continues to be a flu vaccine, but even today, flu vaccines face a number of challenges. Dr. Tumpey was formerly a U.S. Department of Agriculture microbiologist at the Southeast Poultry Research Laboratory in Athens, Georgia. 21. pp. One of them reported ill to the infirmary on March 4, 1918. So the Spanish flu would have originated in France. They also mockingly called it “the Neapolitan soldier,” which was the title of a popular song that was very catchy… just like the flu. Eva Van Alstine is sick with pneumonia (…) Ralph Lindeman is still quite sick (…). Within four days post infection, mice infected with the 1918 virus experienced similar lung complications, suggesting that this was a unique aspect of the 1918 virus’ severity.14, The impact of the 1918 virus on lung tissue was also studied using a human lung cell line (known as Calu-3 cells). In mice, the H1N1 Spanish flu is extremely virulent, generating 39,000 times more virus particles than a modern flu strain. CDC conducted two tiers of approvals: first by CDC’s Institutional Biosafety Committee and the second by CDC’s Institutional Animal Care and Use Committee, before work in the laboratory began. Then, a few days later, on May 28, the Spanish king Alfonso XIII fell ill with this plague (he survived). Terrence Tumpey et al. The picture on the right shows how when the polymerase (PB1) gene of this same virus is exchanged with that of the 1918 virus, the resulting virus’ ability to replicate (i.e., make copies of itself) is greatly enhanced. The H7N9 virus has so far caused 1,568 human infections in China with a case-fatality proportion of about 39% since 2013. No. Movement and mobilization of troops placed large numbers of people in close contact and living spaces were overcrowded. 2002. U.S. and global influenza experts who attended the meeting agreed that we still face great challenges to prepare for future flu pandemics, but part of the solution is recognizing these challenges and working together with the rest of the world to address them. Vol 96. But according to experts, all the pandemics that occurred after the tragedy were caused by derivatives of the H1N1 influenza that caused the Spanish flu. Vol 437 (6). Topical Press Agency/Stringer. 1651-1656. The earlier sequencing efforts led by Dr. Taubenberger and Reid had suggested that the 1918 virus’ gene segments were more closely related to avian influenza A(H1N1) viruses than H1N1 viruses found in other mammals. As part of security and safety considerations, CDC’s Office of the Director determined that only one person would be granted permission, laboratory access, and the tremendous responsibility of reconstructing the 1918 virus. (Photo: National Library NZ/Public domain), A “purulent bronchitis” first broke out in Etaples in late 1916. However, the authors believed the virus likely obtained its HA from avian viruses, but were unsure how long the virus may have been adapting in a mammalian host before emerging in pandemic form. Named after St. Cyprian, a bishop of Carthage (a city in Tunisia) … Photo credit: Angie Busch Alston. It began in January 1918, a few months before the outbreak in the military camps. The 1918 virus proved lethal for the chicken egg embryos, similar to the effects caused by contemporary H1N1 bird flu viruses.14 Notably, comparison experiments using human seasonal influenza A(H1N1) viruses did not have this destructive effect on chicken embryos. Updating the accounts: global mortality of the 1918–1920 “Spanish” influenza pandemic. This collaborative effort advanced understanding of the deadliest flu pandemic in modern history and has helped the global public health community prepare for contemporary pandemics, such as 2009 H1N1, as well as future pandemic threats. For more information on the 1918 pandemic, see CDC’s 1918 (H1N1 virus) website. The victims of the 1918 Spanish flu suffered greatly. In fact, doctors didn’t know influenza viruses existed. However, as his experiments involving recombinant flu viruses with some but not all of the 1918 virus’s genes showed, it was not any single component of the 1918 virus but instead the unique combination of all of its genes together that made it so particularly dangerous.
