What is a common cause of pericarditis?

Viral infections are indeed one of the most common causes of pericarditis. This inflammation of the pericardium, the sac-like structure surrounding the heart, can often occur following a viral infection, such as those caused by viruses like Coxsackievirus or influenza. The inflammatory response from the body to the viral infection leads to irritation and can result in pain and other symptoms associated with pericarditis.

Other pathogens, such as bacteria, can also cause pericarditis, but they are less frequently the primary cause compared to viral infections. Allergic reactions and autoimmune disorders can contribute to pericarditis, but they are not as common as viral infections in the general population. Understanding these common causes helps medical professionals identify and manage the condition effectively.
