Flu

It seems like everyone is falling ill these days. Infectious inflammatory diseases can lead to inflammation of the heart muscle, known as myocarditis. The condition could resolve without any treatment. However, in some cases, this inflammation could progress to chronic heart failure.

Myocarditis is an inflammatory disease that involves the infiltration of heart muscle tissue by inflammatory cells. The most common cause of myocarditis is a transient viral illness. So far, 20 types of viruses have been identified that can cause myocarditis. These include enteroviruses, which cause intestinal inflammation, mouth ulcers, and rashes; adenoviruses, which cause eye and throat inflammation; viruses associated with mononucleosis (EBV, CMV); influenza viruses; hepatitis viruses (Hepatitis C, Hepatitis B); and most recently, the coronavirus (COVID-19).

I have the flu. Two nights with sirens in the middle of the night (Yemenite missiles attack) and the flu, and I feel like a zombie.
