Absolutely, I also had a strange flu that could have been it in early to mid February. First I dismissed Covid,but later I did find a one hop link with someone who was tested positive. But until I can get tested (or my intermediary) its just guesswork.

None of those cases tested positive, but what kind of test did they have? PCR only identifies an active infection. Need antibody testing if not currently infected.

I don’t know. I can only assume they took this into account. I don’t want to be condescending, but do you really think that you just thought of a rather trivial catch that a bunch of expert virologists didn’t think of?

I don't want to be condescending, but did you ever stop to think that the serum tests were not available then?

If they did PCR tests, and didn’t consider that N days (I don’t know the number) after infection you don’t have virus RNA anymore, they’re stupid. Really stupid. If they did think of it and now the guy claims this proves there was no virus flying around, he’s simply lying. Until shown otherwise, I will assume that the leading virologist in Germany and a respected public figure is neither stupid nor lying.

The question rather is if someone is able to pass on the virus, which is the relevant point today. And the PCR test is perfectly suited to check that.
