BBC health journalist Laura Foster can’t get the first days of the pandemic out of her head; the stunned silence of the newsroom as the first lockdown was announced, the chaos and noise at the supermarket and the empty streets of London.

But even though she was a reporter covering every twist and turn of the story, she still can’t remember the first time she heard about long Covid.

The world was so engrossed by the immediate threat that few paid attention to what was happening around the edges; the people whose lives didn’t move on after that little red line disappeared from their test and whose symptoms never went away.

And that problem was getting bigger and bigger by the day.

We visit the UK’s very first long Covid clinic where healthcare workers started learning about this life-shattering disease in the hospital car park - and we find out why recovering from long Covid is a lot like training for the Olympics.

What did we know back then – and what do we know now? And are we really any closer to seeing the end of long Covid?

Details of organisations offering information and support with long Covid are available at bbc.co.uk/actionline.
