I'm sure it's different because mine was not a virus....but I was hospitalized with food poisoning when I was 6 weeks pregnant. The doctors all told me that there was VERY LITTLE risk to the baby. They did an ultrasound (actually my first one) just to be on the safe side, but really were not concerned about baby.
The rest of my pregnancy was uneventful, and baby was big and healthy so I'm assuming it was all harder on me than on her.
Best wishes if you are indeed pregnant :)
