Tropical and subtropical regions of the world frequently experience dengue, a virus spread by arthropods. Clinical signs of the disease include asymptomatic infections, undifferentiated fever, dengue fever, which causes a fever, headache, retroorbital pain, myalgia, and arthralgia, and a severe version known as dengue hemorrhagic fever/dengue shock syndrome, which causes hemoconcentration, thrombocytopenia, and bleeding tendency. Myocarditis is the most prevalent form of the cardiac problem associated with dengue that is now being detected more frequently. Although both direct viral infection and immune-mediated damage have been proposed as the causes of myocardial injury in dengue myocarditis, the primary mechanism is still uncertain. Because it is asymptomatic and difficult to diagnose, dengue myocarditis occurs seldom. Dengue myocarditis is almost always self-limiting, and it is very uncommon for the condition to progress to a severe myocarditis that results in dilated cardiomyopathy. Acute myocarditis as well as dengue hemorrhagic fever were both identified in the patient. Five days of treatment led to a better state.

Dengue myocarditis is almost always self-limiting, and it is very uncommon for the condition to progress to a severe myocarditis that results in dilated cardiomyopathy. A case of dengue hemorrhagic fever with myocarditis as a symptom has been reported. A supportive management approach helps the condition.
