SARS-CoV-2 deletion mutations may have attenuated infectivity in some strains

A team of researchers at the University of Hong Kong has identified a panel of SARS-CoV-2 variants, called Del-mut, which contains a deletion in the S1/S2 junction. Upon investigating one of the deleted variants in animal models, they found that Del-mut-1 is attenuated in its ability to cause disease or pathological changes.

Chicago seroprevalence study shows COVID-19 cases 16 times higher than currently predicted

A startling new case study of Chicago, led by a team of researchers at Northwestern University in Illinois, USA, suggests a 16-fold higher incidence of SARS-CoV-2 infection than previously thought. This is judging from seroprevalence (antibody presence blood testing) figures, rather than the number of RT-PCR-positives reported there (via swab sample testing of symptomatic patients).
