DS had a positive PCR on January 4th. He did 10 days isolation as was testing positive on LFT until day 10. He's had a bit of a runny nose for a couple of days and not himself this evening, have just checked and he has a temperature. Does he need another PCR test? Advice online is very confusing - I thought there was no point doing a PCR within 90 days as it was likely to be positive still, but it seems to say do one with new symptoms? I don't want him missing more school for a positive test caused by the January infection, but equally don't want him to spread it if it's covid. Could it be a covid reinfection so quickly? Any advice welcome, thank you.
