Unique binding of delta variant may explain high transmissibility

Unlike other SARS-CoV-2 variants, the delta variant can attach to copies of itself, forming larger aggregations, or clumps, of viral particles, suggests a study by scientists at the National Institutes of Health. The researchers ...

New knowledge about airborne virus particles could help hospitals

The risk of being exposed to COVID-19 particles increases with shorter physical distance to a patient, higher patient viral load and poor ventilation. Measurements taken by researchers at Lund University in Sweden of airborne ...
