Some excerpts
The masks recommended during the 1918 pandemic were made of heavy-duty six-ply cotton gauze. They were thick and no particular joy to wear. People who refused to wear them or couldn’t be bothered were called “mask slackers” or “mask scoffers.” During World War I, the term slacker described people who neglected their patriotic duty, almost as bad as being a draft dodger.
In Walla Walla, the chief of police, John Haven, refused to enforce a state mask mandate. He pointed out that he was going to meet heavy resistance and, anyway, that he had no authority to carry out a state directive, only city ordinances. Still, he also openly defied the instructions of the city’s health officer, J.E. Vanderpool, to follow the state health officer’s guidance.
Even as people dropped dead in Walla Walla and rural southeast Washington, business owners pushed to have their establishments — saloons and billiard halls — reopened in defiance of advice from most doctors and health officials. The Walla Walla police chief’s determination not to enforce a state edict is mirrored today by a number of sheriffs in rural Washington who have said they will not enforce Gov. Jay Inslee’s mask requirements. The sheriff of modern-day Lewis County told his people, “Don’t be a sheep.”
Yakima was less reluctant to crack down on scoffers and slackers if they were doing business with the public. The city's sanitation inspector arrested 15 people for “working or transacting business in a public place without wearing gauze masks prescribed by the city health commissioner,” according to a 1918 article in the Spokesman-Review. The problem was the merchants, not their customers. The business community held that the city had no authority to mandate masks.
Then, as now, health officials were divided on whether masks truly prevented the spread of Spanish influenza. Many understood that the chances of transmission were worse in enclosed public spaces, like churches and movie theaters, but opinion was divided on the efficacy of masks outdoors. Some believed the fresh air fought the flu, and encouraged people to open their windows and let in the bountiful breeze.
