The contact tracing in US is non-existant. My town has tracers but they dont seem to do much. Our neighbour was positive but wasn't even asked where she went.

The contact tracing in US is non-existant. My town has tracers but they dont seem to do much. Our neighbour was positive but wasn't even asked where she went. BTW has any country with good contact tracing posted any details about where most people get infected? I can't believe we're 6 months into this and still don't know if grocery shopping is risky or not. In the US I read all the updates but still dont know who is getting infected or where.

In Germany, the consensus is that indoor 15+ minutes is risky. So outdoor farmers market, beach, takeaway are all fine. But for supermarkets, everyone has to wear a mask to keep the air safe to breathe. Smear infection appears highly unlikely. So grocery shopping can be both risky or safe, depending on whether it's inside or outside and whether people wear masks or not. Accordingly, most infections occur at private parties, in indoor restaurants, and in crowded factories, like meat processing plants.

This. I doubt the human capital required would make any financial sense for many companies. Digital contact tracing, on the other hand, is also a bust.

Here in Oregon, the latest update was that they had fallen under the 95% benchmark for contact tracing. I don't know the details on what that 95% measures. Also, they mentioned that while in the past, most case counts were from breakouts, that has changed. Now most case counts are "sporadic" cases, meaning no known infection source. The implication is that it's just out there in the general public now. Oregon also currently has lousy test availability, at least as of a couple of days ago. One person I know seeking a test was basically denied - they couldn't even get scheduled. Something about too many tests being sent from Oregon to California and Arizona.

Transmission varies widely by individual. This preprint estimates that 10% of infected people cause 80% of infections. https://wellcomeopenresearch.org/articles/5-67 https://wellcomeopenresearch.org/articles/5-67 There's also plenty of research showing that the "three C's" are major factors: closed spaces, crowded places, and close contact. In fact if we could just cut down on the superspreading events, that might be enough to knock the average reproduction rate below 1. https://arstechnica.com/science/2020/06/just-10-20-of-covid-19-cases-behind-80-of-transmission-studies-suggest/ https://arstechnica.com/science/2020/06/just-10-20-of-covid-...
