I know no one can say either way until we get antibodies testing but does this sound like a covid 19 pattern.
Dd (14yo) skied in Italy. 11 days after came out of school with a high temp. 38.
She also had headache achy body and a sore throat. As she had been to risk area she was tested but it was negative. 6 days later she got a cough lost her voice and still had a headache. All in she was poorly for 2 weeks.
Her dad and myself both got coughs and tired but I wouldn't say we were ill.
I then got transient hives 5 weeks later for about 3 days. Around this time my son (12) who had been the only non affected one got chilblains which I now suspect were covid toes.
Could her test have been a fast negative. It was very early in the pandemic.
