Hi @heidi2020 and welcome to Mayo Clinic Connect. It's good that you stressed HIGH Factor VIII in all caps. I see what you mean that most available information is dedicated to deficiency rather than over-production. I hope that by starting this discussion, other members with high factor VIII will join in.

As for living with a chronic illness and COVID, we have many members who are in the same situation as you are, albeit with different conditions. I recommend following the COVID-19 group here: https://connect.mayoclinic.org/group/covid-19/

In particular, you may be interested in these discussions:

- I'm high-risk. How to stay safe when things start opening again? https://connect.mayoclinic.org/discussion/covig-19/

Heidi, what have you learned about factor VIII and aging? Do risks increase with age?
