Quite an interesting programme (Long Covid) on Radio 4 this morning about long-term symptoms of Covid-19, presented by Adam Rutherford. The programme starts with Rutherford being interviewed on the Today programme in mid-March, at the time he contracted Covid-19, and his saying that he expected to recover from it relatively quickly. Six months on he still hasn't fully recovered. The programme points out that the people suffering from these long-term symptoms include those who are young and fit with no underlying health conditions.

(There was an earlier programme on this subject, on File on 4, but I only caught the last 10 minutes or so of it when it was broadcast and haven't yet got around to listening to the download.)
