And understanding the full story of Spanish flu could help develop vaccines to protect us from the next flu epidemic — an epidemic that is inevitable, as Hultin told TIME in 1998. September 2001. [25] The disease had been observed in Haskell County in January 1918, prompting local doctor Loring Miner to warn the US Public Health Service's academic journal. 11533-11536, Ervin Fodor et al.

Note: using one’s mouth to draw virus into a pipette is not considered a safe laboratory practice today. [129], In New Zealand, the flu killed an estimated 6,400 Pakeha and 2,500 indigenous Maori in six weeks, with Māori dying at eight times the rate of Pakeha. The genome is the complete list of genetic instructions that make up an organism, similar to a blueprint used for construction. Countries did not want to lower national morale or cause panic while also fighting what was then the largest and most costly war in history. All of these resources, tools, technologies, programs and activities are excellent tools for pandemic planning, and pandemic planning itself has improved significantly since 1918. [228], In 2018, Michael Worobey, an evolutionary biology professor at the University of Arizona who is examining the history of the 1918 pandemic, revealed that he obtained tissue slides created by William Rolland, a physician who reported on a respiratory illness likely to be the virus while a pathologist in the British military during World War One. Reconstruction of the 1918 virus also was approved by the National Institute of Allergy and Infectious Disease (NIAID) within the National Institutes of Health (NIH), which partially funded the project. Therefore, it plays an important role in spreading influenza infection. Oxford and his team postulated that a precursor virus, harbored in birds, mutated and then migrated to pigs kept near the front. Christopher Basler et al. A picture of Johan Hultin excavating a body from the Brevig Mission burial ground. [67], In 1993, Claude Hannoun, the leading expert on the Spanish flu at the Pasteur Institute, asserted the precursor virus was likely to have come from China and then mutated in the United States near Boston and from there spread to Brest, France, Europe's battlefields, the rest of Europe, and the rest of the world, with Allied soldiers and sailors as the main disseminators. [30] It reached North Africa, India, and Japan in May, and soon after had likely gone around the world as there had been recorded cases in Southeast Asia in April. [83] The fact that most of those who recovered from first-wave infections had become immune showed that it must have been the same strain of flu. These viruses are called “recombinant viruses.”, The fully reconstructed 1918 virus was striking in terms of its ability to quickly replicate, i.e., make copies of itself and spread infection in the lungs of infected mice. 10717-10723, Ann Reid et al. [100] Nevertheless, actions were taken. [102] To a large extend, the New York City health commissioner ordered businesses to open and close on staggered shifts to avoid overcrowding on the subways. 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). (2013) used a simple epidemic model incorporating three factors to infer the cause of the three waves of the 1918 influenza pandemic. The combination triggered similar symptoms in animal testing. Because pigs are more readily infected with avian influenza viruses than are humans, they were suggested as the original recipients of the virus, passing the virus to humans sometime between 1913 and 1918. The left picture shows replication of a human seasonal flu virus called Tx/91 in cell culture. [69][70] However, no tissue samples have survived for modern comparison. A picture of Johan Hultin at the Brevig Mission gravesite in 1997, 46 years after his first attempt to rescue the 1918 pandemic flu virus. [144] 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. The death toll is typically estimated to have been somewhere between 17 million and 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in human history.[4][5]. Barbara Jester et al. [176] Historian Nancy Bristow has argued that the pandemic, when combined with the increasing number of women attending college, contributed to the success of women in the field of nursing. Within a week, that number had quintupled. Dr. Tumpey was formerly a U.S. Department of Agriculture microbiologist at the Southeast Poultry Research Laboratory in Athens, Georgia. (2007) reported that monkeys (Macaca fascicularis) infected with the recreated flu strain exhibited classic symptoms of the 1918 pandemic, and died from cytokine storms[221] – an overreaction of the immune system. However, the genome of an influenza virus consists of single-stranded RNA instead. [88], In the Pacific, American Samoa[155] and the French colony of New Caledonia[156] also succeeded in preventing even a single death from influenza through effective quarantines. [164] If extrapolated from the extensive data recorded from Chinese cities, the suggested mortality rate from influenza in China as a whole in 1918 was likely lower than 1% – much lower than the world average (which was around 3–5%). 2002. In the absence of such obvious markers, Dr. Reid and her fellow researchers concluded that there were likely multiple genetic factors responsible for the 1918 virus’ severity.
