Touch transmissibility of Covid
Anybody know where I can find real data? Not CDC or NIH
My son has severe OCD and is worried about spreading/catching covid
Only if you smear your body with DMSO or something like that. Viruses and spike proteins can both be transmitted aerosolized through the air. But touch? Maybe via liquids.

10 reasons airborne transmission of sars-cov-2 appears airtight
“This is the week the dam broke. Three new commentaries came out…in top medical journals — BMJ, The Lancet, JAMA — all making the same point that aerosols are the dominant mode of transmission,”
I remember the early days, where “wash your hands” was the mantra, and everyone was talking about how long the virus could live on different surfaces. The new thinking is “fooey on fomites” (surface transmission).
I guess it’s still possible to stick a large enough inoculum into your nose or eye to get an infection, but from what I’ve read inhaling a lung full of aerosol deep into your lungs is how you get really sick.
Here’s another: https://www.medscape.com/viewarticle/934837
COVID-19 Data Dives: Why Arguments Against SARS-CoV-2 Aerosol Transmission Don’t Hold Water
If you read the comments, I actually addressed an issue I was interested in… That vocalization was the primary generator of aerosols. The author gave a reply that he agreed vocalization probably generates 10 times the aerosols as normal breathing.
You might distract your son from the obsession with surfaces & washing hands, but shifting the focus to avoiding aerosols. When out in public, I don’t avoid the un-masked guy quietly sipping on his coffee; it’s the gaggle of gals chattering away with their loose fitting masks hanging away from their made-up faces that is generating aerosols.
In restaurants & pubs, I still go inside; but know which way the wind is blowing and sit at a table where fresh air is coming in the open door. If you’re good, you can even see where the AC recovery vent (that recirculates air) and avoid this area, as all the air in the room is drawn back to this point.
You don’t get COVID from surfaces… You get it from swapping air with others indoors! The physics of avoiding this is actually a fascinating challenge.
