I am a healthy 28 yr old. I just found out I have shingles. I only have a small rash on my right side. I am wondering how do I give others the chicken pox's? Is it through contact with the rash,contact in general, saliva, etc? I am supposed to attend a party on Saturday. There will be one pregnant woman there, and a child over one who has only been vaccinated for the chicken pox but has not had them. Is it safe
