Figure 6

Distribution of ratios of titers T1/T2 according to time of infection (days). Dots represent the ratio of T1/T2 mean values (cut off value = 1). Values from IgM + HWs (black dots) and IgM—HWs (gray dots) were grouped by time (days) since infection. IgM + vs IgM—HWs titers were compared by Mann Whitney test (significant values are shown over discontinuous lines). Significant p value < 0.05.
