VEGFA and dengue disease: The VEGF levels in DHF and DSS, and sVEGFR-1 levels in DSS were significantly higher than those of DF or healthy controls on the day of admission (day 0); however, 2–4 days later (convalescence), their levels had gradually declined to comparable levels with DF, febrile illness, and healthy subjects by the convalescent phase (day 4; VEGF DF: 0.61±+0.24 ng/ml, febrile illness: 0.57±0.11 ng/ml, and healthy subjects: 0.52±0.17 ng/ml; sVEGFR-1 DF: 180.9+55.3 pg/ml, DHF: 223.6±136 pg/ml, febrile illness: 201.3±167.1 pg/ml, and healthy subjects: 195.1±59.1 pg/ml).
