Keeping baby from getting sick

Long story short, my 2 year old, husband, and self have all gotten some nasty sickness (like 104 degree fever). Thankfully my 4 week old has t gotten sick. Any tips on how to keep her healthy?? Or how to bond with her without getting her sick? I know the obvious - stay out of her face, wash my hands, etc. But I normally snuggle with her and kiss her and all that. How do I keep bonding with her while trying not to expose her to my germs? Thanks in advance! I am so terrified of her catching this.
