It doesn't seem like CA has a well publicized number you can call for advice (yet?) but you should call your hospital and ask them for guidance instead of going in. I'm currently traveling in Europe and that's been the MO here - you call a hotline and until recently they then told you whether to go in or not and they now come and test you at your home if it's deemed necessary. CA might not have a number or clear process yet but your hospital should at least have some guidance.
