it is important to be aware of this, and to know symptoms to watch out for. But this sort of condition is not something that is unique to Covid-19 (although obviously we don't know whether it's more likely to cause it than are other viruses). Awareness is a sensible response. Further fear and panic are not.
Absolutely. This is basically why a fever lasting longer than 5 days in a child needs medical attention - to rule out anything more complicated going on under the surface. It’s probably nothing serious, but it needs attention to be certain.

We are truly lucky to have the NHS, it has some amazing people working in it (and amazing scientists behind the scenes too) they will get to the bottom of this and honestly, looking at my daughter 18 month on from near total organ failure, you would never guess she had been ill at all.
These sorts of reactions are rare, but as long as they are recognised, they are treatable.
All viruses are capable of some weird ass stuff, the only difference is that doctors aren’t usually having to learn everything about one all at once, globally. Which is why slowing down the spread is so important, it gives them more time to understand what the virus is doing and how best to stop it.
