Cross posted from another thread since I wanted to better understand Myocarditis:
I’m glad this was brought up, it is important to understand Myocarditis (from Myocarditis Foundation):
The most common cause of Myocarditis is a Viral Infection. acute Myocarditis is a well known complication of influenza infection. The clinical expression varies from asymptomatic to fulminant myocarditis, which can result in severe hemodynamics dysfunction, necessitating high-dose catechilolamimes and mechanical circulatory support.
Many viruses are associated with myocarditis, including viruses that cause the common cold (of which are 5 existing Covid strains that predate Covid 19), Covid 19, hepatitis B and C, parvovirus and herpes.
