What are the causes and symptoms of pericarditis?
The viruses that cause pericarditis include those that cause influenza, polio, and rubella (German measles). In children, the most common viruses that cause pericarditis are the adenovirus and the cocksackievirus (which is most likely to affect children during warmer weather). Although pericarditis is usually caused by a virus, it also can be caused by an injury to the heart or it can follow a heart attack. It may also be caused by certain inflammatory diseases such as rheumatoid arthritis or systemic lupus erythematosus. Bacteria, fungi, parasites, tuberculosis, cancer or kidney failure may also affect the pericardium. Sometimes the cause is unknown. There are several forms of pericarditis, depending on the cause.
