  • a The serotype was determined using a serotype-specific one-step SYBR green I-based RT-PCR.

  • b Negative results were obtained using the serotype-specific RT-PCR; positive results were obtained using a dengue virus-specific IgM/IgG capture ELISA and the Platelia Dengue NS1 Ag ELISA.

  • c Negative results were obtained using the serotype-specific RT-PCR, the dengue virus-specific IgM/IgG capture ELISA, and the Platelia Dengue NS1 Ag ELISA.
