Does anyone have a good explanation for the statistics of these types of data.
For instance, I've heard keep six feet away. However, I assume six feet is the distance where the chance of contracting is <0.1%, at five feet it is 1%, etc. etc. Nothing is black and white.
Is the chance of contracting it from a surface meaningful? Or simply the equivalent to "it is possible to catch it from someone 15 feet away even if extremely slim"
- crispinb 7y agoI don't have stats or references, but I heard on a pretty reputable podcast a couple of days ago that physical contact appears to be the biggest single vector for SARS-CoV-2. Hence the huge emphasis on hand washing.
- arkitaip 7y agoAnd here I thought that hand washing was recommended like crazy to prevent people from getting the virus into their mouth, eyes and nose. The lack of accurate information is maddening.
- lutorm 7y agoI think that's what the grandparent is referring to: "physical contact" as opposed to "in aerosols". I don't think they meant actual physical contact with infected people.
- IAmGraydon 7y agoWhat makes you think that isn’t accurate?
- crispinb 7y agoYes - that's what I mean. Virus gets onto hands via touching objects & surfaces, and from there to face. Also (to be fair) if you want to increase your chances of getting accurate info you probably need to go to more credentialled sources than some random guy reporting on an unnamed podcast in an HN comment ;)
- Enginerrrd 7y agoSix feet comes from the settling distance curves for droplets of different sizes. There may well be a hard cutoff where the probability is negligible under normal circumstances.
- swader999 7y agoIt can transmit between people much farther. The bus study that used cctv footage was further apart than five meters.
- aksss 7y agoIs that with a sneeze propellant or just normal suspension from carriers breathing?
- prostheticvamp 7y agoSneeze, although it’s got a long tail (approx 30 ft, which is ridiculous).
