@CDC’s new guidance recommends #vaccinated people in areas of high or substantial transmission to mask when in indoor public spaces. Why? As the @CDCgov director explained new data finds vaccinated people with #Deltavariant can carry the same viral load as those not 💉 (1/7)
Back on May 13, when @CDCgov first changed their guidance, #DeltaVariant made up about 1.4% of all reported cases. Now it makes up 83% of cases (2/7). 
This raises questions about how easily #vaccinated people can transmit #Covid_19. It Is important to point out there is little correlation between viral load and symptoms. One can have a high viral load, but few symptoms. The vaccines are still doing their job (3/7).
Remember vaccines work at preventing severe disease and hospitalization. According to the @HHSGov data, 97% of hospitalizations and 99.5% of deaths related to Covid-19 are in those who are unvaccinated (4/7).
What does it mean for you? According to @CDC data 67% of the US population lives in an area with high or substantial transmission. This is mostly in areas where vaccination rates are low, less than 40%. Look at the map below to find what transmission is like where you live (5/7).
The guidance also recommends regardless of transmission in your area, vaccinated ppl exposed to someone w/#Covid_19 be tested 3-5 days after & wear a mask in public indoor settings for 14 days or until they a negative test result (6/7).
As I’ve said throughout this pandemic – we are in this together. Be kind, #MaskUp , and get vaccinated when you can (7/7).
