Chickenpox (also called varicella) is a contagious disease that causes fever, tiredness and a blistering, red and itchy rash. Contagious means a disease can spread from one person to another.
Chickenpox is contagious until your child’s fever is gone and the rash has formed scabs. Most children who have chickenpox will not have the disease again later in life.
There is a time called the incubation period when a person might be contagious, but does not have symptoms yet. The incubation period for chickenpox is 1-3 weeks.
