IL10 and dengue disease: Interleukin-10 (IL-10) levels were measured by ELISA, and IL-10 promoter variants (-1082G/A; -819C/T; -592C/A) were genotyped by direct Sanger sequencing to determine a possible association with susceptibility to dengue and disease severity.<h4>Results</h4>No chikungunya or Zika viruses were detected.
