We hear often about how delta is more transmissible, but we don't hear much about why that's the case or how that impacts exposure risk.

A new study by Li and colleagues is out on Virological that provides some insight:https://t.co/EiwAJmrgcI

In short:
-Delta may be more transmissible because there's more of it, more quickly after exposure
-Vaccines still work against delta
-Taking other precautions (masks, distancing, limit crowds, stay outdoors, ventilation, hand washing, disinfection, etc) will further reduce risk.
