    This window is why contact-tracing has to be very very fast—especially for people who cannot stay home for work but have a large number of contacts, many of whom potentially not personally-known to them. Current discussions are ignoring realities of this virus and its victims.https://twitter.com/AdamJKucharski/status/1260839061318705152 …

    Really useful analysis – in the first 3 days after exposure to SARS-CoV-2, there's a high chance of falsely concluding that the person is negative. Suggests very small window in which it's posible to detect infections in the crucial pre-symptomatic period. https://twitter.com/JustinLessler/status/1260732616841596929 … pic.twitter.com/niEkYo3GCn

        The problem this exposes is that even if contact traced very quickly, they will be likely to come up negative on a test even if infected. Wonder if they repeated this with a different test (e.g. saliva test) the results would turn out differently.

        Maybe those with significant exposure will need to isolate until ~7d from exposure, at which point testing will be the most sensitive. Or maybe serial testing. It seems there is still a lot unknown right now and this data isn't perfect.

        Isn’t it the opposite? That study suggests there’s no point in testing someone soon after contact because you’re very likely to get a false negative.

        Depending on the nature of the contact, they could be asked to or required to quarantine?

        Right. What should have happened is that you repeatedly and universally test anyone performing any essential operating jobs during the 2-4 months of lockdown so that you don't rely on contact tracing alone to nab those cases. Horse is way out of the gate on that here though.
