From https://www.bbc.co.uk/news/health-54648734 https://www.bbc.co.uk/news/health-54648734 "Covid test-and-trace: Is backwards contact tracing the way forward?" > "Coronavirus does not spread evenly. Most people who get the virus won’t pass it on to anyone at all. But a small number of people will spread it widely. Scientists estimate as few as 10% of infected people are responsible for 80% of infections." Based on this, they go on to explain why, if it's true, it becomes worthwhile to do backward contact tracing to reduce R.

A colleague of mine was infected, became symptomatic and tested positive, and results took several days to come back. The whole time he was at home with his family waiting for results, he quarantined at home but had contact with his family. He tested positive, but they never did. More credence to the idea that some are super spreaders and some are not.

  Meanwhile I met my family for 2 hours, I started having a fever and immediately quarantined myself to another location. I told them to open all the windows of the flat, they didn't take me seriously. They all got COVID-19 from me.

  This also happened to me. I had minor symptoms, but they didn’t feel like anything worse than bad allergies. My wife is in health care and is tested twice a week so I figured if she doesn’t have it then I must not have it either. That was until I lost my sense of smell. At the time I got my positive result back from the lab I had been experiencing covid symptoms for 9 days. I was doing nothing to shield the other 3 members of my household and none of them got it either.

I read that is what the Japanese did from the start (backwards tracing), and it worked well at the time. Something like the 80/20 rule was mentioned, that a minority of infected people were responsible for the majority of the spread.
