Increased SAR-CoV-2 shedding associated with reduced disease severity despite continually emerging genetic variants

Abstract: Since the first report of SARS-CoV-2 in December 2019, genetic variants have continued to emerge, complicating strategies for mitigating the disease burden of COVID-19. In this study, we investigated the emergence and spread of SARS-CoV-2 genetic variants in Missouri, examined viral shedding over time, and analyzed the associations among emerging genetic variants, viral shedding, and disease severity. The study population included COVID-19 positive patients from CoxHealth (Springfield, Missouri) and University… Show more

“…Earlier in the pandemic, the D614G mutation in SARS‐CoV‐2 was found to be associated with high infectivity, and it was the predominant global strain by June, 2020 54–56 . The coronavirus genome is highly susceptible to mutations, resulting in genetic drift that may escape immune recognition 57 .…”

[54][55][56] The coronavirus genome is highly susceptible to mutations, resulting in genetic drift that may escape immune recognition. 57 Emergence of a new SARS-CoV-2 variant B.1.1.7 in the United Kingdom, B.1.351 in South Africa and P.1 in Brazil posed new challenges but were downgraded from WHO category "variants of concern" to the category "variants being monitored," on September 21, 2021.…”
