PRNT values by age and model fits for infants with and without atypical patterns for DENV-1, -2, -3, and -4. Average decay rates were statistically significantly different between atypical and non-atypical patterns for DENV-1 and -4. For all serotypes, PRNT values in atypical patterns were mostly higher than in non-atypical patterns. For DENV-1 and -3, examples of antibody increases can be seen that were too small to be considered serologic evidence of dengue infection but too large to be within range of the average variance.
