Table 4.
CHIKV RNA detection rate among 469 samples tested by RT–qPCR. The table shows the proportion of patients with RNA detection for each factor: gender, age groups, regions, years, and clinical diagnoses. The Chi-square or Fisher’s exact test was used to compare the differences in the RNA detection rate among groups for each factor.
