Any contact tracing will produce false positives and false negatives. You will notify 20-50 people per infected person, most of them will not be infected. We only have a problem if the number of false positives is in the 200+ range and the

They would need to collect data again now to get a better result. Otherwise the data is the same as on the day the test was made.

There was also much less radiation that got out in the Fukushima accident. Levels are so low, that you can't make predictions that are bases on real data. You can only extrapolate the cancer risk from higher doses. Every coal and gas p

That is not what we see. Mortality for 65+ is way above the baseline because of covid19.

Best data is excess mortality. Many deaths won't be attributed to covid19 but still caused by it. Here an explanation: https://twitter.com/firefoxx66/status/1249996541424816128

I really hope Google and Apple will implement the proposed protocol from DP-3T and give audited and open source apps more control over how the contact tracing is done.

Some of the attacks seem to be high cost, low payoff. Have you read the newer version? There is a new proposal that would protect against most of these attacks.

Have you taken a closer look at the technology? https://github.com/DP-3T/documents The nice thing about this technology is, that it will stop working as soon as there are no more cases.

Is it really worth it to track 0.1-1% of the population for a few days? I don't really see how this level of investment is worth it. I'm also not sure as to how widespread it has to be, with the 2. proposal from DP-3P, you won&#x2

You exchange a one time id with each close proximity. If you test positive, you publish your recorded close proximities ids on a public server. Authorities can supply you with a one time tocken with the test result to append said server. Th

You don't need surveilance. All recorded contacts can be stored locally and only informed once a positive test is returned. More information here: https://www.pepp-pt.org/

The number of people that are infected doesn't tell you that much about R0. You can get R0 from the increase in daily new deaths and the generation time between infections, given that the quality of care stays constant. Serological tes

So 22% don't have any vaccation.That is insane. If the sick leave is limited, it isn't worth much. 38% without any sick leave is already pretty bad. How many of the rest can take 14-21 days of payed sick leave?

The key is to only use evidence in court that was not used to identify the perpetrator. If a piece of evidence is used to identify, you select for the population that matches that property.

The problem in such cases is the prior. If a false positive is 10%, 1%, 0.1% or 0.01% makes a huge difference. With 0.01% and two different tests, you will get a false positive in every 100'000'000 tests. Testing twice solves many
