Dengue Fever and myocarditis with cardiogenic shock
Myocarditis is a rare complication of the virus that causes Dengue fever, an infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets, or into dengue shock syndrome.
Your son's present symptoms suggest heart failure rather than pneumonia. This requires frequent observations with a cardiac echo, as well as continued therapy to support his heart. Carnicor is not a drug used in the US, and I have no information about its effectiveness. The treatment of heart failure requires care, usually in a major hospital with specialized cardiology services, and often includes medications such as Diuretics, ACE inhibitors, and vasodilators like Hydralazine and Nitrates. Other information about treatments you can find in the article about heart failure.
Luckily, the type of cardiomyopathy caused by a viral illness is often self-limiting and a full recovery quite possible!
Hope this helps,
