This used to be one of the most com­mon child­hood dis­eases, how­ev­er use of the chick­en­pox vac­cine has sig­nif­i­cant­ly reduced its pres­ence in the com­mu­ni­ty. The first symp­toms can be a fever or run­ny nose fol­lowed by a rash which appears in crops of small, watery blis­ters on the back, chest andor scalp. Your child is con­ta­gious one day before the rash appears and until no new blis­ters have appeared for 24 hours. Most chil­dren with chick­en pox break out with new spots for three to five days and are no longer con­ta­gious after six to sev­en days into the illness.

The incu­ba­tion peri­od of chick­en­pox is 10 to 21 days after being exposed to some­one who has the disease.
