How to stay healthy if your SO has the flu?

So my fiance just came down with the flu. threw up 2 days in a row now. I'm 7 weeks pregnant and afraid I might get the flu. I'm using disinfectant spray on everything he touches. he's taking immune supplements and flu meds. And I'm taking care of him making sure hes hydrated and his fever stays down. I've been washing my hands after I touch him but is there anything else I should be doing to not get sick? I know probably staying away from him is best but I can't not take care of him. I am in the other room while he sleeps but does anyone have and tips?
