Bolded lines are from
https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-research/surface-transmission.html
Many people are thinking that the risks from surfaces is near zero, due to a recent CDC report.
When you look, and think, deeper at the data, you see the the risks are real.
The article mentions,
Each contact with a contaminated surface has less than a 1 in 10,000 ( risk of infection)
What if you touch a hundred contaminated surfaces a day. Doors, light switches, microwave door, put some dishes away, handle someone else's phone, faucet handles.
10,000 divided by 100(touches per day) = 1 in 100 ( risk of infection per day ).
So, in just 100 days, you are infected.
In just over 3 months, you are infected.
EDIT: After posters rightfully pointing out that some of my conclusions are wrong. It is wrong to say "you are infected", you might get lucky! I put it this way for drama. Embellished. But the average is either right or close. Also some say, less than 10,000, but as pointed out below, there is some indication that the less than 10,000 is an underestimate)
EDIT 2:
I did a sample of 1,000 , the median person had COVID before day 67
The AVERAGE amount of days before a person caught COVID was 100, so about 3 months.
The luckiest person, of the 1,000 had COVID on before day 721
102 people of the 1,000, so more than 10%, had COVID by day number 10.93
BTW, I believe they included surfaces that just had a person breath in the same room. Contamination by airborne particles.
This line shows that surface spread is real.
Hand hygiene is a barrier to fomite transmission and has been associated with lower risk of infection
This mentions efficiency of surface to hands and then to mouth.
But what about the efficiency of a pacifier or a shared cigarette or silverware.
The efficiency would be much higher, along with the risk of infection.
The efficiency of transference of virus particles from fomite surfaces to hands and from hands to mucous membranes on the face
This next line seems to suggest that much of the risk was calculated using outdoor environments, while later, in the same article mention that the surface risks are much less in the outdoor environment.
Some studies estimated exposure risks primarily using outdoor environmental SARS-CoV-2 RNA quantification data.
