The median CD4 counts 6 months before and after dengue diagnosis were 123 cells/mm3 (IQR = 79–303 cells/mm3) and 144 cells/mm3 (IQR = 74.5–251 cells/mm3), with median lowest CD4 count of 45 cells/mm3 (IQR = 37–75.5 cells/mm3) (Supplemental Table 1). This evidence concerns the gene CD4 and dengue disease.
