Answer

Dengue affects people of all ages. However, children younger than 15 years typically present with only a nonspecific, self-limited, febrile illness. In endemic areas, a high prevalence of immunity in adults may limit outbreaks to children.

In Southeast Asia, where dengue is hyperendemic, dengue hemorrhagic fever usually affects children younger than 15 years. However, in the Americas, where dengue is becoming progressively hyperendemic, dengue hemorrhagic fever shows no age predilection.
