Would really welcome a bit of advice please.
My 10 year old son recently had covid - he tested positive on 31 January. Isolated for full 10 days. His lateral flows just got fainter and fainter.
We went on holiday over half term and he was definitely testing negative on 16 Feb when we had to test in order to fly.
My son has been a bit sniffly / a little under the weather this week but honestly didn't think much of it. Just been giving him a bit of Calpol before bed etc, he's been going into school.
Son is staying over at his dad's tonight. His dad just messaged me to say he'd done two covid tests on him and both positive.
This has completely thrown me. Surely he can't have covid again so soon?
I've tried looking online for advice but it's not very clear.
Are tonights positive lateral flows a result of the previous infection from a few weeks ago? But if that was the case wouldn't he have carried on testing positive, rather than eventually having negative lateral flows at the end of his isolation?
Am a bit concerned as I work full time and my parents, who are both in their 70s, do a lot of after school childcare for me to help me out. Obviously don't want to put them in a vulnerable position.
