Calling deep cleaning “a distraction,” public health experts welcomed the news, saying there is little evidence that contaminated surfaces spread the virus. A much greater threat, they add, is the exhaled breath of infected people. “This virus largely spreads through the air, not via surfaces,” said Dr. Ashish K. Jha, dean of the University School of Public Health, on Twitter. “Do basic hand hygiene, absolutely,” he said. “But focus on masks, ventilation and keeping air safe.” For over a year, we’ve shared a collective sense of paranoia — dubbed “hygiene theater” — about touching ATMs, grocery bags and even the day’s delivered mail. https://www.mercurynews.com/2021/04/06/cdc-update-weve-over-cleaning-to-stop-covid-19/
