Final count for unofficial survey: COVID at PAGE
Here is the final update:
Total replied: 133
33 positive, 100 negative/not tested, 24.8% positivity rate.
Among 59 who did not have prior infections:
19 positive 40 negative, 27.5% positivity rate.
Among 74 who did have prior infections:
14 positive 60 negative, 18.9% positivity rate.
Among 50 who did have prior infections in 2022:
2 positive 48 negative, 4% positivity rate.
Both people with positive teste got infected in February 2022
(sorry, I did an error in my prior post about this group)
Among 24 who did have prior infections earlier than 2022:
12 positive 12 negative, 50% positivity rate.
Not sure what does it mean, likely the effect of the small sample size
Thank you to those to participated.
The document is/will be available for further input and more elaborate research of the results:

Three of us who had Age >=60, got rebound infection (75% out of 4 people); for two, the second symptoms were worse than the first round. One person (younger guy < 30 years old) did not have a rebound. Assuming 2% rebound probability, we observed an event with the probability <0.001, looks like we were really lucky :)
