OROPESA FERNANDEZ, Suset et al. Diagnóstico de un brote de infección respiratoria aguda en niños menores de 3 años en Santiago de Cuba. Rev Cubana Med Trop [online]. 1999, vol.51, n.1, pp. 58-58. ISSN 1561-3054.

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 smaples 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 circuclation of the influenza A sybtype H₃N₂ in that province.
