While it is often idiopathic or without a known cause, pericarditis can also be triggered by various factors. Understanding these underlying causes is essential for accurate diagnosis, effective treatment, and prevention of recurrence. Ø Viral Infections: One of the primary causes of pericarditis is viral infections, particularly those caused by the coxsackievirus and echovirus. These viruses can directly invade the pericardium, triggering an inflammatory response. The immune system's reaction to the viral presence can lead to the release of inflammatory chemicals, causing the pericardium to become irritated and inflamed. Ø Bacterial Infections: While less common, bacterial infections can also result in pericarditis. Bacteria such as Streptococcus, Staphylococcus, and Mycobacterium tuberculosis can in
