The section that stuck me the most was: “Scientists are calling for ventilation systems to be overhauled like public water supplies were in the 1800s after fetid pipes were found to harbor cholera. Cleaner indoor air won’t just fight the pandemic, it will minimize the risk of catching flu and other respiratory infections that cost the U.S. more than $50 billion a year, researchers said in a study [1] in the journal Science on Friday. Avoiding these germs and their associated sickness and productivity losses would, therefore, offset the cost of upgrading ventilation and filtration in buildings.” This seems to be a significant shift if it pans out.
