Is it safe for the daughter to visit?

The mother is currently undergoing chemotherapy for cancer that is spreading through her body, and as of Tuesday, she will be starting another round with a new drug (Xeloda).

The daughter was diagnosed with pneumonia last Tuesday with pneumonia, and was given a penicillin shot. She also has a prescription for amoxicillin. As of this posting, she has an internal temperature of 105, with symptoms such as coughing and a headache becoming progressively worse.

The two major questions I’d like to get an opinion on are:
1) Should the daughter head to the ER/24 hour clinic immediately?

2) Is it likely that it will be safe for the daughter to come visit mom by Tuesday?

Thanks!
