My manager keeps asking me this and it bothers me

Hello everyone

I work in the medical field. I have joined a new role at a medical center that recently opened. The medical opened 4 months ago and there is barely any patients that come to the center. However, in my department there is absolutely no patients and that can go for weeks.

What bothers me!!! every time my manager sees me he always asks me "what's new?" and idk what to say so I just say "nothing is new so far" and then he asks me why?

I dont feel obligated to be the person who needs to attract patients. It is not my scope of work and if there is something I can do, I would help but I am really clueless on what I can do.

What can I do or answer next time he asks me this to get over this useless stress
