Longer duration of acute infection with B117 variant relative to non B.1.1.7 SARS-CoV-2

“These data offer evidence that SARS-CoV-2 variant B.1.1.7 may cause longer infections with similar peak viral concentration compared to non-B.1.1.7 SARS-CoV-2. This extended duration may contribute to B.1.1.7 SARS CoV-2’s increased transmissibility”

The mean duration for when B117 was replicating and accumulating within the body was 5.3 days – compared to an average of two days for other variants.

It typically takes eight days for the immune system to clear B117, compared to 6.2 days for different variants, the study found.

And in total, the overall period of infection lasts 13.3 days for the UK variant and 8.2 days for non-B117 versions of the virus
