title: Investigations on the presence of hemagglutination-inhibiting antibodies to dengue virus in apparently healthy subjects of several counties in Romania.
abstract: The presence of hemagglutination-inhibiting (HAI) antibodies to dengue virus, types 1, 2, and 3 was studied in 1219 apparently healthy subjects of four counties in Romania. The proportion of positive reactions was of 0.40% to type 1, of 1.23% to type 2, and of 3.90% to type 3. Antibody proportion was different from one county to another.
