The means of N.A titers as determined by BHK and FcγR-expressing BHK cells from serum samples after the dengue season (labeled as Non patient 2 in Additional file 1: Figures S1A, S1B) were 4.76 ± 0.34 and 3.65 ± 0.3 for DENV-1; 4.79 ± 0.32 and 3.26 ± 0.24 for DENV-2; 2.97 ± 0.28 and 2.65 ± 0.17 for DENV-3; 2.53 ± 0.1 and 2.32 ± 0 for DENV-4. The gene discussed is FCGR2A; the disease is dengue disease.
