CDC finally recognizes that the risk of transmission by touching contaminated surfaces is very low. Credit for changing horses midstream. Now everyone should revert to regular cleaning (stop overcleaning) and pay attention to the air instead (ventilation + filtration). No excuses twitter.com/ProfCharlesHaa…

So good to have the CDC leading the way again.
Fomites and surfaces can theoretically transmit COVID-19 but risk is very low. Wash hands but time to rethink the deep cleaning...it's a bad use of time, energy and resources.

@DFisman Totally. Every time someone tells me about all the deep cleaning they are doing, or planning, to stop covid, I want to hear about the ventilation. Sure, wash your hands. But let's not pretend we can spray, sanitize and wipe our way out of this.

Updated @CDCgov science brief:
**The risk of surface transmission is low compared to airborne transmission**
They talk about airborne transmission as an important mode, finally!! [Many months late, but we'll take it]

The correct sentence would have been:
"The relative risk of fomite transmission is considered low compared with direct contact, short-range airborne, or long-range airborne transmission"
They keep confusing failed #DropletDogma with the real short-range airborne transmission
Because you CANNOT have longer-range airborne (what @CDCgov calls "airborne" now) without short-range airborne being much more important. This drawing from @linseymarr says it all:
And we know aerosols >> droplets in close proximity when talking: sciencedirect.com/science/articl…pic.twitter.com/1gWMfYrpe0

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. cdc.gov/coronavirus/20…

CDC states the risk of infection with #SARSCoV2 through contaminated surfaces or objects (fomites) is considered low. It’s important to update the public with this info. Focus on masks, distancing & ventilation (lots of fresh air) as mitigation measures. cdc.gov/coronavirus/20…

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. cdc.gov/coronavirus/20…
La CDC🇺🇸 ha determinado que el riesgo de contagiarse por #covid19mx al tocar superficies contaminadas es bajo. #CovidSeRespira. Menos sanitización y más ventilación. Cuidar más la nariz que los dedos. Usar😷que ajusten, para filtrar el aire respirado.

The principal mode people are infected with SARS-CoV-2 is through exposure to respiratory droplets carrying infectious virus. It is possible for people to be infected through contact with contaminated surfaces or objects (fomites), but the risk is be low. cdc.gov/coronavirus/20…

📍 New CDC guidance now admits fomite (surface) transmission of #SARSCoV2 is very rare and low. Glad science is updating.
This also means droplets and aerosols (Microdroplets) are the the main #COVID19 culprits.
