As a COVID-19 summer surge sweeps the country, deep cleans are all the rage.
National restaurants such as Applebee’s are deputizing sanitation czars to oversee the constant scrubbing of window ledges, menus, and high chairs. The gym chain Planet Fitness is boasting in ads that “there’s no surface we won’t sanitize, no machine we won’t scrub.” New York City is shutting down its subway system every night, for the first time in its 116-year history, to blast the seats, walls, and poles with a variety of antiseptic weaponry, including electrostatic disinfectant sprays. And in Wauchula, Florida, the local government gave one resident permission to spray the town with hydrogen peroxide as he saw fit. “I think every city in the damn United States needs to be doing it," he said.
To some American companies and Florida men, COVID-19 is apparently a war that will be won through antimicrobial blasting, to ensure that pathogens are banished from every square inch of America’s surface area.
But what if this is all just a huge waste of time?
In May, the Centers for Disease Control and Prevention updated its guidelines to clarify that while COVID-19 spreads easily among speakers and sneezers in close encounters, touching a surface “isn’t thought to be the main way the virus spreads.” Other scientists have reached a more forceful conclusion. “Surface transmission of COVID-19 is not justified at all by the science,” Emanuel Goldman, a microbiology professor at Rutgers New Jersey Medical School, told me. He also emphasized the primacy of airborne person-to-person transmission.
