Confirmatory diagnosis of dengue was performed by laboratory tests, such as serology for anti-dengue IgM and/or IgG (12/15, 80.0%) [31–35, 37, 38, 41–45] dengue nonstructural protein 1 (NS1) antigen test (3/15, 20.0%) [35, 36, 45], identification of viral ribonucleic acid (RNA) using polymerase chain reaction (PCR) (4/15, 26.7%) [34, 35, 38, 40], and isolation of viruses (1/15, 6.7%) [38]. Here, CD40LG is linked to dengue disease.
