Association of neutralizing antibody titres (Neut50) with viraemia and changes with time. The Neut50 titres were measured in patients with DF (n = 18) and DHF (n = 22) during the acute DENV2 infection and correlated with the viral loads. A significant and negative correlation of viral loads with Neut50 antibody titres were seen in patients with DF (Spearman r = − 0.75, p = 0.003) (a) but not with DHF (Spearman r = − 0.26, p = 0.23) (b). Neut50 titres were also compared in patients during acute illness (day 4 to 8, n = 40) and during the convalescent phase (day 21 to 30, n = 14) (c). ***p < 0.001
