[Subgroups classification of strains of the respiratory syncytial virus isolated in an outbreak in Ciudad de La Havana].
A high number of acute respiratory diseases was detected among children under one year admitted in a hospital of Havana City. 25 respiratory syncytial virus strains were obtained from 93 patients studied. Viral isolations were multiplied in HEP-2 cells and after observing a cytopathic effect of 80%, they were classified into subgroups by the indirect immunofluorescence technique, using anti-protein G antibodies from the respiratory syncytial virus. All the samples studied were classified within subgroup A. It is the first time a study like this is conducted in our country, which allowed us to deepen into the viral cause of these diseases and to know that the subgroup A of the respiratory syncytial virus circulated during the outbreak.
