On Oct. 31, 1918, the Los Angeles City Council passed anti-influenza ordinances requiring tenants of properties to clean their front doorways and sidewalks every morning, and the other creating an official “clean-up” week to disinfect all sections of the city.

City Council members also approved staggered business hours to reduce crowding on streetcars, effective on November 9. By then the daily tally of new cases fell below 800 for the first time in a month.
