They've lumped together a few things - do you know that most of the increases shown by that that line is autism?
Allergies could be long covid, as could certain newly developed sight and hearing conditions. But without knowing more detail, you can't really tell.
According to the Epilepsy Society, there is an increase (around 55%) on onset of epilepsy (in those who did not have the conditions before) in the first six months after covid (substantially more than after say flu). The overall numbers of those with epilepsy against the size of the total population are not large even after this increase however.
Long covid isn't always recognised and termed as such, because people don't always include it as the cause of eg the rise in immune system issues, muscular skeletal issues, debilitating brain fog etc. For this chart they've clearly used pre-covid definitions (so I expect the rise in muscular skeletal issues might be a long covid consequence.
I'd love to know the fuller story behind the autism/epilepsy/sight/hearing line !
