Ridiculous JT, if he's not coughing at all, and has been immunised. Bearing in mind WC lasts months, is she saying she wont have him for months?? He is not sick, she cannot refuse to have him, and if she does, you dont pay her, simple! Except of course not so simple as you need childcare! If he's not coughing, he is not contagious to other children. Found this....
Your GP may prescribe a course of antibiotics if whooping cough is diagnosed during the first three weeks of the infection. This will prevent the infection being passed on to others.
It is important to take steps to avoid spreading the infection to others, particularly babies under six months of age.
Children with whooping cough should be kept away from school or nursery until after they have finished taking antibiotics for five days. The same advice applies to adults returning to work.
As a precaution, household members of someone with whooping cough may also be given antibiotics and a booster shot of the vaccine.
If whooping cough is not diagnosed until the later stages of infection, antibiotics will not usually be prescribed. The bacterium that causes whooping cough will have gone by this time so you will no longer be infectious and antibiotics will not make a difference to your symptoms at this stage.
The last paragraph basically implies that you wont be contagious anymore as you have had it for so long, therefore your household are not suddenly going to get it if they havent already, so really she shouldnt worry.
