how worried should I be?

[FrostyTheSnowgirl]

My son has been at his dad's today and has been playing with another family member's child. I've just been told that the child has been to the doctors tonight with suspected swine flu. Should I be overly worried that he's been in contact and take him to doctors tomorrow or wait and see?

I should also add that my sister is pregnant and im worried it could harm her baby

Wait and see. Nothing they will do prophylactically now. Keep an eye and if you want Tamiflu to reduced duration then ring as soon as he developes symptoms (it is only really effective if taken in first 36-48hrs....the sooner the better).
