RESUMO
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.

In November, 1996, there was an outbreak of acute respiratory infection in children under 3 in the province of Santiago de Cuba. 7 samples of nasopharyngeal exudates were received to determine the causal agent of the outbreak by indirect immunofluorescence technique (4 positive samples, 57.14). They were inoculated in MDCK cells culture and those cases that presented positive hemadsorption (6 isolates, 85.71) were analyzed by indirect immunofluorescence techniques (6 positive samples, 100) and immunoperoxidase (5 positive samples, 83.3). All the positive samples were classified as influenza A (subtype H3N2) which confirms what is reported in literature in relation to the circulation of this virus during that year at the national and international level. This paper allowed to know the causal agent of the studied outbreak of acute respiratory infection and to determine the circulation of the influenza A subtype H3N2 in that province.
