A study of healthcare workers demonstrated that the presence of antibody to SARS-CoV-2 spike protein or to nucleocapsid provides strong protection against infection with this virus for up to six months.
SARS-CoV-2-related multisystem inflammatory syndrome in children (MIS-C) can be severe and life-threatening. New data suggest that the degree of elevation of spike protein receptor-binding domain antibodies could serve as a diagnostic marker of MIS-C as well as point to potential pathogenic processes.
Minks farmed for their fur are acquiring SARS-CoV-2 from humans and transmitting it back, a classic scenario for possible genetic mutation that could create a mismatch with vaccines under development, the World Health Organization reports.
In temperate regions other than China, human seasonal coronaviruses circulate most heavily during the winter months, overlapping with influenza and respiratory syncytial virus — and this may be the eventual pattern for SARS-CoV-2.
Although the pandemic of SARS-CoV-2 (COVID-19) has been relatively benign in children compared to adults, there is growing concern about an emerging syndrome that causes severe, sometimes fatal, outcomes in pediatric patients.
