Paragraph: In March 2020, as cities around the world announced "shelter-in-place" or "self-quarantine" orders in an effort to reduce the spread of COVID-19, social media users started to circulate an image that supposedly showed a newspaper clipping from 1918 with a similar announcement in the town of Kelowna, British Columbia: The clipping reads: Public Notice. Notice is hearby given that, in order to prevent the spread of Spanish Influenza, all Schools, public and private, Churches, Theaters, Moving Picture Halls, Pool Rooms and other places of amusement, and Lodge meetings, are to be closed until further notice. All public gatherings consisting of 10 or more are prohibited. D. W. Sutherland, Mayor. Kelowna, B.C., 19 October 1918. This is a genuine newspaper clipping that was published in the Kelowna Record in 1918 as this Canadian town, as well as the rest of the world, fought to prevent the spread of the H1N1 virus, commonly and misleadingly called the "Spanish Flu." The clipping was archived by the University of British Columbia and can be viewed here. Kelowna, of course, was not the only city to issue such an order. We searched the archives of Newspapers.com and found several similar announcements in cities across the United States. On Oct. 10, 1918, for instance, Des Moines, Iowa, Mayor Thomas P. Fairweather announced that "in order to prevent the spread of Spanish Influenza and to protect the public health and safety," he was directing "all public places of amusement, including theaters, moving pictures houses, dance halls and public dancing places, pool and billiard halls, skating rinks, outdoor athletic events, all public congregating places subject to unusual congestion, be closed." Thu, Oct 10, 1918 Page 6 The Des Moines Register (Des Moines, Iowa) Newspapers.com Mobile, Alabama, took these closures one step further. In addition to closing restaurants and businesses, Mobile also asked people to refrain from kissing: Tue, Oct 8, 1918 10 Knoxville Sentinel (Knoxville, Tennessee) Newspapers.com In 1918, just like today, individual cities and states made the decision to close schools, businesses, and public gathering places. According to a recent study from the Journal of the American Society of Cytopathology,cities that implemented strict social guidelines during the early days of the 1918 pandemic saw lower transmission rates and reduced total mortalities. Claim: "A newspaper clipping from 1918 documents a ""public notice"" from the city of Kelowna, British Columbia, announcing that schools, movie theaters, and other public places would be closed to prevent the spread of ""Spanish Influenza."" "
Output:
During the 1918-19 H1N1 "Spanish" influenza pandemic, which infected a fifth to a third of the world population, and during which 50 million people have died worldwide, including an estimated 675,000 Americans, the United States has adopted a range of nonpharmaceutical (public health) interventions. These measures, which were similar to those currently adopted, included closure of schools and churches, banning of mass gatherings, mandated mask wearing, case isolation, and disinfection/hygiene measures. However, these measures were not implemented at the same time or for the same duration in different cities, nor were they uniformly followed. A recent analysis concluded that in some cities (San Francisco, St. Louis, Milwaukee, and Kansas City), where the measures were implemented early, they reduced transmission rates by up to 3050%. Cities that implemented such measures earlier had greater delays in reaching peak mortality, and had lower peak mortality rates and lower total mortality. The duration that these "social distancing" measures were kept in place correlated with a reduced total mortality burden. Although we still have no known effective therapy or vaccine prevention for this coronavirus, and the world is a quite different place than it was 100 years ago, the efficacy of the measures instituted during the 1918-19 pandemic gives us hope that the current measures will also limit the impact of the COVID-19 pandemic.
