The U.S. Centers for Disease Control last week warned the Delta variant of the virus is so contagious, vaccinated people who do get infected could be just as big a risk to others as people who aren't vaccinated.
The new requirement, which will be phased in over several weeks in August and September, is the most aggressive step the city has taken yet to curb a surge in cases caused by the delta variant.
The findings have the potential to upend past thinking about how the disease is spread. Previously, vaccinated people who got infected were thought to have low levels of virus and to be unlikely to pass it to others. But the new data shows that is not the case with the delta variant.
President Joe Biden is calling on states and local governments to join those that are already handing out dollars for shots. New York, the nation's biggest city, started doling out $100 awards on Friday.
The internal documents also cite studies from Canada, Singapore and Scotland showing that the delta variant may pose a greater risk for hospitalization, intensive care treatment and death than the alpha variant, first detected in the United Kingdom.
The dead included a 82-year-old man in Akseki’s Kepezbeleni neighborhood, where some 80% of the houses were incinerated, the district’s governor, Volkan Hulur, told the the state-run Anadolu Agency.
