[38], The second wave began in the second half of August, probably spreading to Boston and Freetown, Sierra Leone, by ships from Brest, where it had likely arrived with American troops or French recruits for naval training. [26] It then quickly spread to the rest of France, Great Britain, Italy, and Spain and in May reached Breslau and Odessa. The movement of soldiers during this time and the transportation from United States between Canada likely had a significant effect on the spread of the pandemic. Centers for Disease Control and Prevention. The end of World War I enables a resurgence of influenza as people celebrate Armistice Day and soldiers begin to demobilize. Studies show a much higher mortality rates in males compared with females. The ages of males dying of the flu shows that tuberculosis was a factor, and as males primarily had this disease at the time of the pandemic, they had a higher mortality rate. This gave rise to the name "Spanish" flu. The vulnerability of healthy young adults and the lack of vaccines and treatments created a major public health crisis, causing at least 50 million deaths worldwide, including approximately 675,000 in the United States. [59] In Europe, five countries (Spain, Denmark, Finland, Germany and Switzerland) recorded a late peak between January–April 1920.[56]. In fall of 1918 the United States experiences a severe shortages of professional nurses, because of the deployment of large numbers of nurses to military camps in the United States and abroad, and the failure to use trained African American nurses. In Newfoundland the pandemic spread was highly variable. [2] However, several theories have been proposed. [183] 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. [61], The basic reproduction number of the virus was between 2 and 3. Maritime quarantines were declared on islands such as Iceland, Australia, and American Samoa, saving many lives.

Trustees of the Boston City Hospital ask mayor for a special appropriation of $3,000 to study the treatment of influenza. In Iran, the mortality was very high: according to an estimate, between 902,400 and 2,431,000, or 8% to 22% of the total population died. [195], Survivors faced an elevated mortality risk. [42] On September 15, New York City saw its first fatality from influenza. [108][109][110], While systems for alerting public health authorities of infectious spread did exist in 1918, they did not generally include influenza, leading to a delayed response. [89], In the Pacific, American Samoa[168] and the French colony of New Caledonia[169] also succeeded in preventing even a single death from influenza through effective quarantines. sfn error: multiple targets (2×): CITEREFTaubenbergerMorens2006 (, sfn error: multiple targets (2×): CITEREFBarry2004 (, sfn error: multiple targets (25×): CITEREFSpinney2018 (, sfn error: multiple targets (2×): CITEREFPattersonPyle1991 (, David Arnold, "Dearth and the Modern Empire: The 1918–19 Influenza Epidemic in India,". [113] Iceland protected a third of its population from exposure by blocking the main road of the island. [140] In Tahiti, 13% of the population died during one month. [119], Due to World War I, many countries engaged in wartime censorship, and suppressed reporting of the pandemic. The only comparable disease to this was the black death, bubonic plague in the 1300s. [87] This more serious type would cause heliotrope cyanosis to develop, whereby the skin would first develop two mahogany spots over the cheekbones which would then over a few hours spread to color the entire face blue, followed by black coloration first in the extremities and then further spreading to the limbs and the torso. [236], On 16 September 2008, the body of British politician and diplomat Sir Mark Sykes was exhumed to study the RNA of the flu virus in efforts to understand the genetic structure of modern H5N1 bird flu. [187], Academic Andrew Price-Smith has made the argument that the virus helped tip the balance of power in the latter days of the war towards the Allied cause. [38] From the Boston Navy Yard and Camp Devens (later renamed Fort Devens), about 30 miles west of Boston, other U.S. military sites were soon afflicted, as were troops being transported to Europe. [114] Wearing face masks became common in some places, such as Japan, though there were debates over their efficacy. [23][24][25], The pandemic is conventionally marked as having begun on 4 March 1918 with the recording of the case of Albert Gitchell, an army cook at Camp Funston in Kansas, United States, despite there likely having been cases before him. However, a first wave of influenza appeared early in the spring of 1918 in Kansas and in military camps throughout the US. [148] Entire Inuit and Alaskan Native village communities died in Alaska. The majority of the infected experienced only the typical flu symptoms of sore throat, headache, and fever, especially during the first wave. The name Spanish flu emerged as a result of media censorship by the military in Allied countries during the First World War. [137] In Sweden, 34,000 died. [74][75][78][173] However, some reports from its interior suggest that mortality rates from influenza were perhaps higher in at least a few locations in China in 1918. [121] The newspapers of the time were also generally paternalistic and worried about mass panic. [134][135] While India is generally described as the country most severely affected by the Spanish flu, at least one study argues that other factors may partially account for the very high excess mortality rates observed in 1918, citing unusually high 1917 mortality and wide regional variation (ranging from 0.47% to 6.66%). [113] By the end of the pandemic, the isolated island of Marajó, in Brazil's Amazon River Delta had not reported an outbreak. [88] The severity of the symptoms was believed to be caused by cytokine storms. [43] The Philadelphia Liberty Loans Parade, held in Philadelphia, Pennsylvania, on 28 September 1918 to promote government bonds for World War I, resulted in 12,000 deaths after a major outbreak of the illness spread among people who had attended the parade. From New Zealand, the flu reached Tonga (killing 8% of the population), Nauru (16%), and Fiji (5%, 9,000 people). However, in Spain, which was neutral during the war, the media was able to widely report the high incidence of death from the illness. [160] The disease spread fastest through the higher social classes among the indigenous peoples, because of the custom of gathering oral tradition from chiefs on their deathbeds; many community elders were infected through this process.[161]. The effort resulted in the announcement (on 5 October 2005) that the group had successfully determined the virus's genetic sequence, using historic tissue samples recovered by pathologist Johan Hultin from an Inuit female flu victim buried in the Alaskan permafrost and samples preserved from American soldiers[232] Roscoe Vaughan and James Downs. [citation needed], The high mortality rate of the influenza pandemic is one aspect that sets the pandemic apart from other disease outbreaks. The virus became associated with Spain as a result. [4] An estimate from 1991 states that the virus killed between 25 and 39 million people. The death toll is typically estimated to have been somewhere between 20 million and 50 million, although estimates range from a conservative 17 million to a possible high of 100 million, making it one of the deadliest pandemics in human history. Modern transportation systems made it easier for soldiers, sailors, and civilian travelers to spread the disease. Oxford and his team postulated that a precursor virus, harbored in birds, mutated and then migrated to pigs kept near the front. [115] To a large extent, the New York City health commissioner ordered businesses to open and close on staggered shifts to avoid overcrowding on the subways. Some historians speculate he was weak from influenza, which was still rampant in Paris. This affected especially WWI troops exposed to incessant rains and lower-than-average temperatures for the duration of the conflict, and especially during the second wave of the pandemic. Vaccines were also developed, but as these were based on bacteria and not the actual virus, they could only help with secondary infections. [88][128] However, a 2018 reassessment in the American Journal of Epidemiology estimated the total to be about 17 million,[4] though this has been contested. [63][62] According to Oxford, a similar outbreak occurred in March 1917 at army barracks in Aldershot,[64] and military pathologists later recognized these early outbreaks as the same disease as the Spanish flu. Kahn has developed a model that can be used on home computers to test these theories. Within days, 522 men at the camp had reported sick. Similarly, in Western Samoa 22% of the population of 38,000 died within two months. Even though there was higher mortality rate in males, each region showed different results, due to such factors as nutritional deficiency. [183] Cities were affected worse than rural areas. In late 1917 and throughout 1918, thousands of male troops gathered at the Halifax port before heading to Europe. Chicago, along with many other cities across the United States, closes theaters, movie houses and night schools and prohibit public gatherings. Seven-hundred and six cases of influenza and 67 deaths are reported in New York City, triggering fear of a recurrence of severe flu activity. The rapid pace of the pandemic, which, for example, killed most of its victims in the United States within less than nine months, resulted in limited media coverage. [249], 1918–1920 pandemic of H1N1 influenza A virus. [188], Many businesses in the entertainment and service industries suffered losses in revenue, while the healthcare industry reported profit gains. The Spanish flu was the deadliest flu pandemic of the 20th century, but there have been others. ", Phillips, Howard.

[citation needed] The war, however, had initially been expected to end quickly but lasted for four years by the time the pandemic struck. Cold-storage plants are used as temporary morgues, a manufacturer of trolley cars donates 200 packing crates for use as coffins. The second wave of flu emerges at Camp Devens, a United States Army training camp just outside of Boston, and at a naval facility in Boston. [139] In the Dutch East Indies (now Indonesia), 1.5 million were assumed to have died among 30 million inhabitants. The origins of the pandemicare debated. [114] The actual enforcement of various restrictions varied. The Spanish Flu pandemic, caused by the H1N1 influenza A virus, began in February 1918 (not 1917) and lasted until April 1920 – nearly 20 years before WWII began. [47] In the United States, ~292,000 deaths were reported between September–December 1918, compared to ~26,000 during the same time period in 1915. The combination triggered similar symptoms in animal testing. It also was home to a piggery, and poultry was regularly brought in from surrounding villages to feed the camp. New York City’s Board of Health adds flu to the list of reportable diseases, and requires all flu cases to be isolated at home or in a city hospital. The disease wasn’t Spanish at all but a misnomer of the times. [64][65], A report published in 2016 in the Journal of the Chinese Medical Association found evidence that the 1918 virus had been circulating in the European armies for months and possibly years before the 1918 pandemic. Historical and epidemiological data are inadequate to identify with certainty the pandemic's geographic origin, with varying views as to its location. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. The 1918 flu, also known as the Spanish Flu, lasted until 1920 and is considered the deadliest pandemic in modern history. The 1918 flu pandemic virus kills an estimated 195,000 Americans during October alone. [99], Studies have shown that the immune system of Spanish flu victims was weakened by adverse climate conditions which were particularly unseasonably cold and wet for extended periods of time during the duration of the pandemic. The 1918 flu pandemic virus kills an estimated 195,000 Americans during October alone. Hanssen, Olav. Four locations are often considered the source of the initial outbreak: Engl… [20] In Spain itself, the nickname for the flu, the "Naples Soldier", was adopted from a 1916 operetta, The Song of Forgetting (La canción del olvido) after one of the librettists quipped that the play's most popular musical number, Naples Soldier, was as catchy as the flu. The majority of men were working along the coast during the summer and it was typical for entire families to move to Newfoundland and work. [93] The virus also killed people directly by causing massive hemorrhages and edema in the lungs.

Bristow on the Influenza Epidemic of 1918", "What can the Spanish Flu teach us about the COVID-19 pandemic? Sykes had been buried in 1919 in a lead coffin which scientists hoped had helped preserve the virus. Public health officials begin education programs and publicity about dangers of coughing and sneezing; careless disposal of “nasal discharges.”. [41] From Freetown, the pandemic continued to spread through West Africa along the coast, rivers, and the colonial railways, and from railheads to more remote communities, while South Africa received it in September on ships bringing back members of the South African Native Labour Corps returning from France. [7] Some analyses have shown the virus to be particularly deadly because it triggers a cytokine storm, which ravages the stronger immune system of young adults. Bg. "[136], In Finland, 20,000 died out of 210,000 infected. Humphries, of the Memorial University of Newfoundland in St. John's, based his conclusions on newly unearthed records. [177] As a whole, accurate data from China's port cities show astonishingly low mortality rates compared to other cities in Asia. [172] However, some contemporary newspaper and post office reports, as well as reports from missionary doctors, suggest that the flu did penetrate the Chinese interior and that influenza was severe in at least some locations in the countryside of China. [94] Modern analysis has shown the virus to be particularly deadly because it triggers a cytokine storm (overreaction of the body's immune system). [22], Other terms for this virus include the "1918 influenza pandemic," the "1918 flu pandemic", or variations of these. Med. [177] For example, the British authorities at Hong Kong and Canton reported a mortality rate from influenza at a rate of 0.25% and 0.32%, much lower than the reported mortality rate of other cities in Asia, such as Calcutta or Bombay, where influenza was much more devastating. [2], Most influenza outbreaks disproportionately kill the very young and the very old, with a higher survival rate for those in between, but the Spanish flu pandemic resulted in a higher-than-expected mortality rate for young adults. The 2009 flu pandemic was the second H1N1 pandemic the world had seen — the first being the 1918 Spanish flu, still the most deadly pandemic in history. [8] Some fatal cases did continue into March 1919, killing one player in the 1919 Stanley Cup Finals. Bombay reported ~15,000 deaths in a population of 1.1 million. While origin theories about the 1918 virus still abound, it was assigned a country specific name: the Spanish Flu. The influenza did not discriminate who was infected, indeed it attacked the socioeconomic status of people. Several explanations have been proposed for this, including the fact that lower temperatures and increased precipitation provided ideal conditions for virus replication and transmission, while also negatively affecting the immune systems of soldiers and other people exposed to the inclement weather, a factor proven to increase likelihood of infection by both viruses and pneumococcal co-morbid infections documented to have affected a large percentage of pandemic victims (one fifth of them, with a 36% mortality rate).
