I'd previously read that COVID-19 might be a cardiovascular disease, which would account for the blood clots and heart stuff. From the OC: Marcus plans to also start collecting data from wearable devices, including Fitbits and Zio patches, which wirelessly monitor heart rhythms. “There may be large numbers of people who are suffering from cardiovascular effects of COVID-19 in the absence of other symptoms,” Marcus says. “I’m worried we’re missing those cases.” I have no idea what it means to regard COVID-19 in cardiovascular vs respiratory terms. I'm just repeating what I think I've read. I really don't understand this stuff.
