SARS-CoV-2 does not infect the entire body in the same way, finds study

COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."

SARS-CoV-2 mutations allow escape from clinical monoclonal antibodies

A new research paper recently uploaded to the preprint server bioRxiv by Jesse D. Bloom et al. (22nd Feb 2021) aims to map all of the currently circulating SARS-CoV-2 lineages with resistance towards LY-CoV555 and LY-CoV016, and document the specific mutations that confer resistance, ultimately suggesting that future monoclonal antibody cocktails should target a more diverse range of epitopes.

Glycan switch may explain why SARS-CoV-2 causes such variable symptoms

Researchers in Portugal have provided evidence that might explain why infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes mild or even asymptomatic illness in some individuals, but severe coronavirus disease 2019 (COVID-19) in others.
