Lower viral loads were observed in the upper respiratory tract of patients infected with BA.1, whereas patients infected with BA.2 and BA.5 had comparable viral loads to those seen with Alpha or Delta. This suggests that viral loads are likely not responsible for the increased transmission of the Omicron lineages.
