RE: Mutation of Coronavirus Is Significantly Increasing Its Ability To Infect16 Jun 2020 00:19
I believe that is the source for the Reuters article which is fairly readable for anyone. https://www.reuters.com/article/us-health-coronavirus-science-idUSKBN23M2SF - it has a tag on about using cotton too.

A genetic mutation in the new coronavirus that significantly increases its ability to infect cells may explain why outbreaks in Northern Italy and New York were larger than ones seen earlier in the pandemic.
People with conditions like asthma, chronic obstructive pulmonary disease, pulmonary hypertension, and smokers have more of the ACE2 receptors on their lung cells than healthy people do, researchers found. In their analysis of lung cell genes from 700 people with these conditions, they also found that other proteins in addition to ACE2 impacted the "viral life cycle." This means genes for those proteins "can be potentially important for SARS-CoV-2 cell cycle and invasion/attachment," they wrote in the Journal of Infectious Diseases. These other genes may also be potential "targets for treating and preventing severe COVID-19 cases," they said. (bit.ly/37HUniF)
But only an hour after virus particles were applied to 100% cotton fabric, the amount of active virus had decreased by 99.9%, and it was completely undetectable in less than 24 hours. "These results have direct relevance to infection prevention and control practices, laundering and waste handling protocols in healthcare settings," the researchers write in a not-yet-peer-reviewed paper posted on Friday on the preprint server medRxiv. "These results suggest that the use of cotton-based fabrics in healthcare settings may present a lower risk during handling for subsequent decontamination and reuse."
