Chickenpox is a mild disease that most children catch at some point. It takes 10-21 days for the signs to show. If you are sure it is chickenpox you do not need to go to your GP unless your child is very unwell.
Chickenpox is most common in children who are between two and eight years old. They can pass it on to others from about two days before the rash appears until roughly five days after. The rash usually appears on the chest and back.
You and your child should stay away from other people until all of the blisters have fully burst and dried up which usually happens five to seven days after the first blister appears. You can take them out if they are well enough, but be careful to keep away from other people.
After the last blister has burst and dried, they are no longer likely to pass the infection on.
Chickenpox spreads from spit, nasal mucus in sneezes and coughs from a person who has chickenpox.
