When Tim Spector tells me that I probably had Covid-19 last March when I was days away from having a baby, it’s hard to ignore him. That’s because Spector is the man who informed the nation about the most predictive (and strange) symptom of Covid-19 last year: the loss of smell and taste.

He breaks the rather alarming news to me with such affability that I forget to retroactively panic. “Maybe your pregnancy protected you from having very extreme symptoms because your immune system would have been working well already,” he says, reassuringly.

Nevertheless, he is confident because, as he explains, losing my sense of smell and taste as I did during the first wave of the pandemic was a textbook symptom at the time and 90 per cent predictive of a positive Covid-19 test.
