*The odds ratio for IgM responses for individual epitope at different time intervals are shown. An arbitrary cut off of 800 average fluorescence units was used in the calculations.

†The epitopes listed are those showing positivity with IgG or IgM responses.

‡Total No of subjects per time interval is shown.
