Modeling study sheds light on SARS-CoV-2 genome packaging

Researchers at the University of North Carolina at Chapel Hill have conducted a study exploring how the spatial patterning of certain genomic RNA regions in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes compaction, packaging, and cyclization of the viral genome.

How do SARS-CoV-2 antibodies change over time in recovered patients?

Researchers studied convalescent plasma from recovered coronavirus disease 2019 (COVID-19) patients, with samples collected up to 34 weeks after recovery. They found IgG antibodies gradually declined with a median half-life of about 60 days.
