@seaspray- Hello. I'm glad that you are staying at home. I have an autoimmune disease that has been dormant for many years and I also have stage 4 lung cancer. Most people's symptoms show up within 14 days (give or take) but the transmission of the virus can take up to a month. If you have been offered testing I'd take it too. I'm also wondering what the time difference is between your self-quarantine and going to Mayo.
This is a complete and easy to understand video from Mayo Clinic. You will really benefit from watching it!
