Mononucleosis Symptoms: 16 Early Warning Signs and Symptoms of Mononucleosis

Cardiac complications

Myocarditis –

EBV infection can cause cardiac complications such as myocarditis, pericarditis, and ECG abnormalities. Myocarditis is characterized by respiratory distress, wheeze, crackles, dizziness, syncope, tachypnea, shortness of breath, cough, chest pain, murmurs, and diaphoresis. Pericarditis patients usually report chest pain, which is relieved on bending forward. On the examination, doctors evaluate the pericardial rub and fever. In the case of a sore throat and cardiac complications, it is important to evaluate if it is rather caused by a group A beta-hemolytic streptococcus because it can be a life-threatening complication if that’s the case.

Renal complications

Renal complications include interstitial nephritis and abnormalities in urine analysis. The patient may also report blood in the urine (hematuria).
