Would you be mad?

Last week I went to visit my aunt and grandmother who live together. I took my two small kids and husband, it was my grandmother’s first time meeting my youngest son. They live 600 miles away. My aunt was hoarse sounding and said “these allergies are horrible!” so I didn’t think much of it. My grandmother was kinda sniffly too but she is in her 80s so I didn’t question it much. Cut to now, we’re back home and all tested positive for Covid. My husband is realllly sick. I texted my aunt because I was worried about my grandmother. She said “we’re good, I think that’s what we had last week when you were here but I thought it was just a cold or allergies”. So basically she knew they were sick and didn’t tell us, and now my whole family is sick. Would you be mad?
