Washington DC, which is classified as an area with a significant spread of infection, also announced that everyone must wear a mask indoors from last weekend.



As the delta mutation spreads rapidly, on the 30th of last month, the number of daily infections in the United States reached 194,000.

New York Times reported that at least 233 people have been confirmed at the Zuckerberg General Hospital in San Francisco and the University of California San Francisco Medical Center, and most of them were investigated as breakthrough infections even after receiving the vaccine.
