What is the COVID-19 delta variant?

The COVID-19 delta variant is now a common variant across the country. There is evidence that this and other variants spread more easily than other COVID-19 strains. These variants are being closely monitored, and more studies are needed. However, vaccination still seems to be effective against the different variants. It’s important to continue to follow public health recommendations, including vaccination, physical distancing, use of masks, hand hygiene, and isolation and quarantine, as appropriate, to limit the spread of COVID-19.
