[Characteristics of the ecology of the eastern equine encephalomyelitis virus in the Republic of Cuba].
Virologic and serological surveys of wild vertebrates carried out in various provinces of Cuba demonstrated definitely that birds were the main hosts of eastern equine encephalomyelitis (EEE) virus in this territory. Fifteen strains of this virus were isolated from 8 species of birds belonging to 5 orders. Isolation of EEE virus from the blood of the endemic genus of iguanas indicates a certain role of cold-blooded animals in the ecology of this agent. Active EEE virus foci have been found in 4 provinces of the Republic of Cuba: Pinar del Rio, Havana, Matanzas and Las Villas. Isolation of a number of EEE virus strains from sick horses during an epizootic in the latter province confirmed the importance role of this agent in the infectious pathology of domestic animals in Cuba. The experimental results suggest that in Cuba there occur at least two types of foci of this infection: forest and water-littoral (fresh-water swamps and lakes, and sea coast with mangrove forests).
