Invasive pulmonary aspergillosis (IPA) is a life-threatening disease commonly affecting the lungs of immunosuppressed patients. Recently, Aspergillosis was diagnosed in immunocompetent patients with viral pneumonia due to influenza virus and coronavirus-19 infections. A series of four immunocompetent patients from different hospitals in Lebanon diagnosed with pulmonary aspergillosis post viral infection is reported. Aspergillosis is an important differential diagnosis in patients with viral infections and worsening infiltrates on chest x-ray, in addition to bacterial and mycobacterial infections with which they share common features. Fungal infections should be suspected early, and treatment should be considered knowing that these infections entail worse outcomes.
