Last week I was away with the in-laws and when we got home on Saturday my nephew was taken to hospital as he hadn't eaten and hardly drank all week plus his dribble smelled (so i was told). He has ulcers in his gums/mouth/throat and the doc has said it's a herpes version of chicken pox and he was made to stay in isolation for 48hrs, he's 2. Both the mum & dad have it aswell although they didnt need to go into isolation, just put on medication. They both have sore throats. As far as I know I didn't catch it, I've not had a sore throat which is the main symptom but I'm 11 weeks pregnant and my mother-in-law keeps saying how worried she is which has now made me worried. Could I have passed it onto my baby without showing signs myself? My 2 yr old did not catch it, thank god. Is there any test or am I worrying unneccessarily?
