What to do??

My partner has been diagnosed with testicular cancer recently he is due to start BEP chemotherapy within a couple of days. We have 4 children ranging in age from 2 to 16. They children with this virus are currently off school and I'm homeschooling. I also work within the hospital environment. The thing I'm trying to figure out is if my partner can stay at his apartment (rents out not currently occupied) then should he to save any risks of infections, the children seeing what's happening on a daily basis and being in the thick of it! This is thinking of him and recovery as quickly as possible to get back to normal life as poss. He would have support and daily calls etc am I being over cautious or what! This is all such a nightmare and such an uncertain time pleas be kind and help with any suggestions.
