Answer

Lung involvement secondary to EBV infection is rare and can occur as a complication of infectious mononucleosis. In healthy individuals, pulmonary manifestations, such as dyspnea and cough, are rare. Chronic interstitial lung disease is reported in immunocompetent patients.

In children with cystic fibrosis, EBV can cause deterioration in pulmonary function that lasts longer than six months after the infection is diagnosed.

In HIV patients, relatively few studies have been conducted to investigate EBV-related pulmonary disease. EBV seems to be related to the development of AIDS-associated non-Hodgkin lymphoma. BAL fluid samples from 72 European patients with AIDS were positive for EBV in five. The patients had fever and low PaO2, with no radiographic infiltrates, and recovery was the rule.

In BMT recipients, EBV-related lung manifestations are among widespread extrarenal manifestations of posttransplant lymphatic disease. A fulminant presentation soon after transplantation is associated with a dire prognosis. Young age and primary infection are risk factors. Patients with EBV infection are at subsequent risk for other viral lung superinfection (eg, severe RSV or Mycoplasma pneumoniae infection).
