Slightly off topic, any connection if blood type plays a role in severity or bearing on symptomatic versus asymptomatic disease? Reason I ask is daughter home from college due to positive test but no symptoms for ten days. Me being immunocompromised, show no signs or symptoms. Son who is O- comes down cold like symptoms. So, it got me thinking that two out of five of us are O- and have shown past and present symptoms of something. In my wife's case (O-) she's had the ***19 twice. Or could there be other underlying reasons aside from blood type?
