Genomic sequencing and neutralizing serological profiles during acute dengue infection: A 2017 cohort study in Nepal.

ABSTRACT: Dengue virus (DENV) is a mosquito-borne flavivirus that poses a threat to nearly 50% of the global population. DENV has been endemic in Nepal since 2006; however, little is known about how DENV is evolving or the prevalence of anti-DENV immunity within the Nepalese population. To begin to address these gaps, we performed a serologic and genetic study of 49 patients from across Nepal who presented at central hospitals during the 2017 dengue season with suspected DENV infection. Of the 49 subjects assessed, 21 (43%) were positive for DENV NS1 antigen; of these; 5 were also anti-DENV IgM+ IgG+; 7 were DENV IgM+ IgG-, 2 were IgM- IgG+, and 7 were IgM-IgG- by specific ELISAs. Seven of the 21 NS1 positive sera were RNA positive by RT-PCR (six DENV2, one DENV3), suggesting that DENV2 was the domi
