DENV types that infected the patients. The types of dengue virus were determined by type-specific real-time RT-PCR.
FcγRIIA-expressing BHK cell line 2.
FcγRIIA-expressing BHK cell line 4.
Days 1 to 3 after onset of the disease.
Days 6 to 14 after onset of the disease.
Samples 1 and 3 were obtained from the same patient, infected with DENV-1.
Samples 2 and 4 were obtained from the same patient, infected with DENV-2.
Serum samples 5 to 14 were obtained from patients 5 to 14, respectively.
Dengue virus types of primary infection in patients 7 to 14 were not determined. Dengue virus types in secondary infection are included in the table.
