Recently, the U.S. Centers for Disease Control and Prevention suddenly changed the guidelines to require people who received the vaccine to wear a mask, and a report containing the reason was released. The transmission of the delta mutation is as strong as chickenpox, and people who have been vaccinated can transmit the virus.



This is Washington Correspondent Kim Soo-hyung.



The



Washington Post has obtained an internal CDC report from the US Centers for Disease Control and Prevention that contains new investigations into delta mutations.



The delta mutation is more deadly than other mutations and is as powerful as chickenpox, so the battle against the virus has changed.



In particular, it has been found that even vaccinated people infected with the delta mutation transmit significant amounts of the virus, similar to those not vaccinated.



That's why the guidelines have been urgently changed to require vaccinated people to wear masks too.



Still, he emphasized that vaccines are still the best weapon against delta mutations.



[Jonathan Reiner/Professor, George Washington University School of Medicine: Delta mutation can kill you. If you haven't been vaccinated, it's still not too late. You can get a vaccine tomorrow.] As the



delta mutation continues to skyrocket, President Biden pressured federal officials to be vaccinated, saying that if they don't get the vaccine, they will have to be tested for coronavirus every week.



It also called for the participation of private companies.



[Biden/President of the United States: Private companies can also legally enforce vaccination. Communities and local businesses can do the same.] They



also proposed a carrot bill that pays $100 for every vaccine given by the federal budget.



An increasing number of regions are also requiring people who have been vaccinated to wear a mask.



In Washington DC, it is mandatory to wear a mask indoors again from Saturday dawn at this time.



However, some Republican lawmakers took off their masks and marched inside the Capitol to protest, and some citizens protested by burning their masks.
