Viral cardiomyopathy

Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the viruses that cause hepatitis A and C, as well as COVID-19, which has been seen to cause this in persons otherwise thought to have a "low risk" of the virus's effects.
