N95 Mask?

Daddy came back from work early today, but he is not his usual self. I heard him tell mummy that he is down with a flu, and he has a fever, a cough & a stuffy nose. I have not had a fever before, and wonder what that is?

Mummy made daddy wear something white on his face, and I heard it being referred to as the N95 mask. Daddy looks different with that white mask on his face. I wonder if he is really Daddy?

I'm still not convinced if that is really Daddy. I'm just smiling for the camera.
