I spent 2.5 years in Thailand and was all good. Then I went to the UK for a visit and got covid in the first week. To be fair, we went to a ton of exhibitions in London and then saw Hamilton in a packed theatre. Plus, no one wears masks anywhere.
My wife got a cold within minutes and tested negative for covid. I then got a slightly sore throat and had a slight brain fuzz. I'm 49 and in good shape. No other symptoms at all and I assumed I was fighting a cold like her. I am journalist and was still able to write. Then my parents tested positive. Both parents are 77 and my mum has a mild lung condition. They both got slight sniffles for two days and were then fine. No other symptoms and as of today are both clear.
Going on timelines, my parents got it after 3 days of us being back from London. If I got it at the theatre, then I was three days too. It took my parents 5 days from testing positive to being clear.
It was kind of scary at first as you don't know how you'll react. Fortunately for us, we got it really mildly. All of us are triple jabbed. A mate of mine here in the UK got it twice. Once at the very start before any jabs and the original strain - and it was awful. He got it again recently after all the jabs and he didn't know he had it (he got tested for work).
I hope you're ok but I wouldn't worry too much.
