Parents are angry that I cancelled plans to have them stay with me for a long weekend. Thoughts?

Husband commutes into NYC every day and I am concerned about exposing them to COVID through him in our small home. With rain expected we will be even more confined and I am not wearing a mask for three days in my home. So much anger from them, what I thought was acting in their best interest has now become an act of selfishness on my part according to them. I have lost perspective. Please help.
