I am 6-7 weeks pregnant and just got my blood results at my doctors, I was upset to find I have low immunity against rubella and must keep away from infected people. I`m now paranoid and work in a small confined office with people who have had shingles in the last couple of months. Am I only at risk when having contracted the virus? Am I safe at work?, how do I know someone has the rubella virus? I don`t want my baby to be harmed, please help me.
