Causes of pericarditis

The cause of pericarditis is often unknown, though viral infections are a common reason. Pericarditis may occur after a respiratory or digestive system infection. Chronic and recurring pericarditis may be caused by autoimmune disorders such as lupus, scleroderma and rheumatoid arthritis.

What is the most common cause of pericarditis?

Viral infection is the most common cause of acute pericarditis and accounts for 1-10% of cases. The disease is usually a short self-limited disease that lasts 1-3 weeks and can occur as seasonal epidemics, especially coxsackievirus B and influenza.
