jmPeople can be infected with SARS-CoV-2 through contact with surfaces. However, based on available epidemiological data and studies of environmental transmission factors, surface transmission is not the main route by which SARS-CoV-2 spreads, and the risk is considered to be low. The principal mode by which people are infected with SARS-CoV-2 is through exposure to respiratory droplets carrying infectious virus. In most situations, cleaning surfaces using soap or detergent, and not disinfecting, is enough to reduce risk. Disinfection is recommended in indoor community settings where there has been a suspected or confirmed case of COVID-19 within the last 24 hours. The risk of fomite transmission can be reduced by wearing masks consistently and correctly, practicing hand hygiene, cleaning, and taking other measures to maintain healthy facilities.
Can we tone down the cleanliness theatre now?]]>covid19 infection pandemic washing fomites disinfection cleaninghttps://pinboard.in/https://pinboard.in/u:jm/b:828752327249/The Scourge of Hygiene Theater - The Atlantic2020-07-27T17:05:04+00:00

jmTo 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.

jm... Rapid treatment of the virus with hot water had little effect on the virus, reducing the titre by around two-fold, but prolonged incubation at 55°C abolished detectable infectivity. However, the addition of any of 1% bleach, 50% and 10% malt vinegar and 1%, 0.1% and 0.01% washing up liquid were all effective at rapidly reducing viable virus below the limit of detection, while a low concentration of vinegar (1%) was no more effective than hot water alone (Figure 1A). In contrast to the plaque assay results, most agents were ineffective at reducing the number of detectable genome copies as determined by RT-PCR, with only bleach having a significant effect (Figure 2A). The data for the plaque assays and RT-PCR assays are compiled in Tables S1 and S2. Thus, while a strong oxidizing agent such as bleach is effective at reducing both genome detection and virus infectivity, low pH and detergent are equally efficacious virucidal agents. These results also indicate that whilst vinegar and detergent disrupt the viral envelope proteins reducing infectivity, only bleach disrupts the viral genome.

jmHorsham District Council has paid thanks to a volunteer who devotes a great deal of time and energy to walking many miles clearing litter from near where he lives as well as surrounding areas.
David Sedaris litter picks in areas including Parham, Coldwaltham, Storrington and beyond. In recognition for all his fantastic work and dedication and as a token of Horsham District Council’s appreciation, the council has named one of their waste vehicles after him. The vehicle, bedecked with its bespoke ‘Pig Pen Sedaris’ sign was officially unveiled by the Lord-Lieutenant of West Sussex Mrs Susan Pyper at an outdoor ceremony on July 23.
Best of all, the article utterly fails to mention who he is. Amazing.

jmSpeaking today, spokesman Charles Stanley-Smith said; "This idea is insane. This area has suffered from dumping due to a lack of enforcement - yet the council now propose to effectively withdraw services altogether. As numerous studies such as 'the broken window hypothesis' indicate, where a small problem is left un-tackled it is likely to become far worse rather than better. In other words, rather than increase enforcement to solve the problem, Dublin City Council is going to remove enforcement. How will this deal with the problem? Imagine if that logic were applied to crime; would the removal of police services in an area help resolve criminal behaviour - or increase it? The answer is obvious."
