Chickenpox can be considered benign because the mortality rate is very low. Children are most susceptible to the disease, but there are cases of chickenpox occurring in pregnant women.

Chickenpox mainly occurs in children, is usually mild and easy to treat. However, if adults are infected, the symptoms are often more severe, and can easily lead to some dangerous complications. Chickenpox in pregnant women can cause complications such as pneumonia for the mother or congenital varicella syndrome for the baby.
