On September 7, 1918, 300 sailors arrived in Philadelphia from Boston, where, two weeks earlier, soldiers and sailors began to be hospitalized with a disease characterized as pneumonia, meningitis, or influenza. The sailors were stationed at the Philadelphia Naval Yard.
On September 11, 19 sailors reported to sickbay with symptoms of “influenza.” By September 15, more than 600 servicemen required hospitalization.
Physicians and other public health workers in Philadelphia first met on September 18 with city officials to discuss what they perceived as a growing threat. Public health officials demanded that the city be quarantined – all public spaces, including schools, churches, parks, any place people could congregate, should be closed. City officials did not want to create panic. They were more concerned that local support for President Wilson’s efforts in World War I should not be disturbed. Anything that would damage morale – or the city’s ability to raise the millions in Liberty Loans required by federal quota – was unacceptable.
The Board of Health declared influenza a reportable disease on September 21, which required physicians to report any cases they treated to health officials. The Board advised residents to stay warm and keep their feet dry and their bowels open. The Board also suggested that people avoid crowds. Read more

The 1918 influenza pandemic did not hit the world all at once, but rather in three waves throughout 1918 and into 1919. Though it is unclear how the influenza pandemic influenced the outcome of World War I, what is undeniable is the pandemic’s connection to the war itself.
The first wave was in early 1918, and may have originated in Haskell County, Kansas, where “18 cases of influenza of a severe type” were reported in January and February. From Camp Funston in Fort Riley, Kansas, influenza travelled to Europe with soldiers going to the battlefront of World War I. The general population picked the disease up from the military, and by June, it was epidemic among the German troops and appearing among civilians in mainland Britain. While this first wave did substantial damage, it was milder than and not nearly as lethal as the second wave, which appeared as the first wave was fading in late August.
The second wave began when three cities on three separate continents experienced outbreaks of influenza almost simultaneously. Boston, Massachusetts in North America; Brest, France in Europe; and Freetown, Sierra Leone in Africa all had influenza appear in their naval yards between August 22 and August 27, 1918. The first cases of influenza in Philadelphia appeared on September 7, when sailors from Boston arrived in the naval yard. By early October, hospital beds in Philadelphia were full, public meetings and church services were banned, schools were closed, and there was a severe shortage of coffins. Beginning in September 1918 and until spring of 1919, the weekly number of influenza-related deaths in Philadelphia dropped below three figures only once. In October alone, over 11,000 Philadelphians died from influenza.
By the end of October, public services and meetings, including school and church, were re-opened. In early November, influenza in Philadelphia had reached its peak and the number of deaths slowly declined. A reported 12,162 people had died by November 2, 1918. The end of the second wave for most American cities, including Philadelphia, came in mid-November. Philadelphia had a small resurgence during the third and final wave during February 1919. By the end of the pandemic, a huge number of people had died. A general estimate for the total number of deaths is 50 million, though estimates range from as low as 25 million to as high as 100 million deaths worldwide. Over 1.5 million of these deaths were in the United States. Whichever way the true numbers run, the loss of life is truly astounding.
