Chickenpox (varicella) is a contagious illness that causes an itchy rash and red spots or blisters (pox) all over the body. Chickenpox can cause problems for pregnant women, newborns, teens and adults, and people who have immune system problems that make it hard for the body to fight infection.
Most people have chickenpox as a child. Most children get chickenpox before the age of 10. About 9 in 10 people have had it by the age of 15. It is uncommon for adults to have chickenpox.hickenpox causes spots (a rash) and can make you feel unwell. Symptoms tend to be worse in adults than in children. Treatments can ease the symptoms until the illness goes. An antiviral drug may limit the severity of the illness if the drug is started within 24 hours of the rash first starting.
