What Is Parainfluenza?
8. Who Is Most at Risk for Developing Parainfluenza?
Any person of any age can contract an HPIV. Most children will have developed and lived through the disease before they are five years old. Though reinfections can and do occur after the first, the second or subsequent infections typically come with less severe symptoms.
Children of certain genders and ages are more at risk for developing complications. For instance, boys are more prone to pneumonia, croup and bronchiolitis than girls, as are children under two. Children between three months and 5 years old are more at risk for croup, while bronchiolitis is more common in children between two and six months.
