CNNCNN — When the novel coronavirus pandemic hit Asia, people across the region were quick to wear masks, with some places like Taiwan and the Philippines even making them mandatory in certain scenarios. On October 24, 1918, the city’s elected legislative body, the Board of Supervisors of San Francisco, realizing that drastic action needed to be taken with over 4,000 cases recorded, unanimously passed the Influenza Mask Ordinance.

Topical Press Agency/Hulton Archive/Getty Images Newspapers, and variousstategovernments in the US, linked masks to the ongoing war on the battlefields of Europe in October 1918 – “Gas Masks in the Trenches; Influenza Masks at Home” promised the Washington Times newspaper on September 26, 1918, reporting that 45,000 masks would be provided to US soldiers to ward off “the Spanish Flu.” When the First World War ended on November 11, gas-mask manufacturers fulfilling government contracts switched to influenza masks. On October 25, 1918, the San Francisco Chronicle ran front page pictures of the city’s top judges and leading politicians all wearing face masks. During the 1918 flu pandemic, scientific research around mask use was still largely anecdotal – and the compelling story of one ocean liner caught people’s attention.
