Am I wrong?

Question:

Am I wrong to be paranoid about getting covid from my dad?

Backstory:

I'm young and still live with my family. My dad is a paramedic and got covid because of his coworker who came in with it, stating that she was immune and refused to wear a mask even with patients. My dad tested positive but is getting better and we're close to the end of our quarantine. I'm having jaw surgery at the end of the year and if I test positive I'm pretty sure they won't do the surgery.
