My childcare source has taken relatives for covid testing. They have tested positive but childcare source has not. Apparently neither have seen each other prior to meeting to do testing. AIBU to think my kids should not go to the childcare source this week? She has said she will get tested and if negative it's okay but is it not true that it can take up to 10-14 days hence the self isolation so testing negative a few days after contact may still mean you still have the virus?
