Meanwhile, its impossible to find good information on how long can children be infectious. My daughter is 3 weeks after first symptoms and we'd like to get her back in kindergarden after 4 weeks.

The same for RT-PCR -- I tested positive one month after first symptoms, but I also have good igg antibodies.

Didn't people do this RT-PCR testing for influenza before? Are RT-PCR tests for influenza still positive one month after first flu symptoms?

I mean, the quality of information you can google up as a COVID-19 patient is absolute shit, most of what google shows is sensationalized news articles directed at the non-positive, scared general public.
