In general, much is still not reliably known about Covid-19 and its long-term effects.
The NHS says one in five people who have contracted coronavirus have gone on to develop longer-term symptoms. It has data showing 186,000 have reported having problems for up to 12 weeks.
But there is also evidence so far, including cases documented in the US, where symptoms have continued for more than six months.
The big problem is there has not been time to glean meaningful data from long-term studies of the condition. Showing the vagaries, early research in the US has suggested anywhere between 10% and 88% of Covid-19 patients will have one or more symptoms for many weeks – or months.
