NYC 'Carefully' Monitoring Delta COVID Variant's Rise, Mayor Says

NEW YORK CITY — The more infectious and more dangerous "Delta" coronavirus variant now accounts for about 23 percent of cases in New York City, health officials said.

Mayor Bill de Blasio on Monday said officials are monitoring the variant "very carefully" amid fears it could spark a resurgence of COVID-19 cases among unvaccinated people.

"The answer to the Delta variant is more and more and more vaccination," he said.
