Acute and convalescent plasma samples were obtained from 101 confirmed primary dengue cases: 48 cases infected with dengue virus type 1, 10 cases with type 2, 42 cases with type 3 and one case with type 4. The hemagglutination inhibition (HI) titers of individual samples were at levels similar to each of the 4 dengue viruses at both the acute and convalescent stages, irrespective of the dengue virus that infected the patients. The results indicate that HI antibodies to dengue viruses are cross-reactive. When an HI test is used as a diagnostic test for dengue virus infection, the cross-reactive nature needs to be considered when interpreting the results.
