Background:

Dengue virus infection is an endemic disease in some regions of Peru. Most of these cases are classified as dengue without warning signs and the reported mortality is less than 1%. However, there are certain conditions associated with the disease that could increase mortality.

Case report:

We present the case of a 48-year-old female patient from a dengue endemic area with clinical and laboratory compatible with dengue disease with warning signs. During hospitalization, she presents hemoptysis and respiratory insufficiency, leading to death.

Conclusion:

It is important to recognize diffuse alveolar hemorrhage as part of dengue respiratory manifestations and to differentiate it from other infectious and non-infectious possibilities in order to provide appropriate and early management.
