Children, travelers and expatriates also had significantly higher concentrations of IL-8 (41.97 {30.02; 55.7}, 52.2 {32.72; 114.69} and 95.31 {31.86; 126.26} pg/mL, respectively) in comparison with malaria-exposed adults (32.2 {14.69; 51.61}; P = 0.0233, P = 0.0029, P = 0.0035, respectively). This evidence concerns the gene CXCL8 and malaria.
