Yeah nah. I agree with the comment you replied to.

The error bars on around 24 hours and more than 24 hours over lap at least a bit.

If I had a tick for 23 hours and the guidelines say ‘more than 24’ I’d be treating it the same as ‘more than 24’ for practical purposes.

There is at least some natural variation in the host and the pathogen for there to be at least some people for who the guidelines aren’t strict enough.

Public health policy is a balance of factors, one of which is trying to not overwhelm services with trivial / non maladies.

The actual error bar of "typical time-to-infection", as per CDC guideline is 36 hours minimum. 24 is my generous amount of error factor in the most optimistic (or worst, if you're a human and not a tick) direction.

So in other words, this was my experience, and it was at least 50% worse in timescale than the cdc predicted
