Figure 1. Circulating DNA levels among study groups according to the day of the blood test.

Day 3 and 4 indicate the duration after the onset of high grade fever. Box-plots graphs extend from the 25^th to the 75^th percentile, and the line at the middle is the median. The error bars extend down to the lowest value and up to the highest. (The outliers are not shown). The Mann-Whitney test was used for comparisons of DNA levels between groups.
