Hi @claireb, I'd like to add my welcome to @loribmt's. You mention that your husband will be starting with a virtual visit. You might find the advice from fellow members in this discussion to be useful:
If you scroll to the end of this web article, you'll also find further information about questions to ask and more. This might be a good starting place to read before talking with someone at the American Cancer Society. They will be able to prepare more in-depth questions specific to your husband.
I'll let Lori and @grandpabob share their experiences about precautions he'll have to take because of the compromised immune system and isolation from family. That is tough. But that is a reality of leukemia with or without COVID. Those will be important and wise questions to ask the care team, too.
