Dd2's best friend has had slap cheek, he only had it mild and by the time the gp diagnosed it he had already been at school and was no longer contagious.
Dd2 now has cold symptoms (slight cough, runny nose and slightly rosy cheeks), she's at home today as she has an eye infection but will be going back to school tomorrow (unless she develops slap cheek).
What are the early symptoms? and what is the incubation period?
