There's still so much to learn about COVID, and this week we have two big things about Long COVID and how long we spread the virus.Firstly, a recent study has drawn a link between hand grip strength and post Long COVID symptoms, especially when it comes to who gets it and how badly.And secondly, a study from Hong Kong has tried to nail down what's going on in a person's immune system and how that effects the duration of shedding the virus.That's on this week's Coronacast.(And please note, we're taking the next few weeks off! But we'll be back in October)
