Neumonía hemorrágica por Influenza virus: diagnóstico virológico / Hemorrhagic pneumonia caused by influenza virus: virological diagnosis

The paper presents the case of a female patient who was admitted to "Calixto GarcÝa" General Hospital with respiratory distress and hypovolemic or septic shock. She was diagnosed with viral hemorrhagic pneumonia. From the endotracheal secretion taken as a sample, the influenza virus was isolated as etiological agent, which, through the hemaglutination inhibition technique, was characterized as a strain belonging to H3N2 subtype, very similar to strain A/Johannesburg/33/94 from the antigenic viewpoint. The patient recovered satisfactorily after being treated with rivabirin.
