Study of arboviruses in Romania (1958--1978). Results obtained in the "Stefan S. Nicolau" Institute of Virology.

The results obtained in the Institute of Virology by the study of arboviruses in Romania are reviewed. Isolation of tick-borne encephalitis virus and detection of specific serum antibodies in humans, animals and migratory birds demonstrate its presence on the territory of Romania. Serum antibodies could also be detected to other three flaviviruses (West Nile, Ntaya, dengue types 1, 2, 3), though none of them could be isolated in our country. However, isolation of Kemerovo and Tahyna viruses and detection of antibodies to these viruses as well as to Calovo virus draw attention to the possibility of human infections with arboviruses belonging to Kemerovo, California and Bunyavirus groups.
