DS has all covid symptoms but negative PCR

[Grandmotherschina]

I’ve got covid
DD has covid
DD2 has covid
DS has the same symptoms as us…but negative LFT and PCR? It’s too much of a coincidence for him to have caught a cold which exactly mimics covid at the same time we have covid surely?

I'd repeat the PCR

The tests aren't 100% accurate so most likely to be false negatives.

DD's BF is the same, symptoms and his two siblings are positive and DD also has it but he's had two negative PCRs. Strange.
