The average daily number of infections is 905, and that number is increasing, according to city health data.Health officials are “very, very carefully” monitoring the variant, Mayor Bill de Blasio told reporters Monday. Nearly 5,400 people in the state are testing positive daily, on average, marking the highest number of new positive daily cases since February, according to the station.President Joe Biden addressed the nation Monday, saying that while omicron is a “cause for concern,” there is no need to panic. Omicron will come to the U.S. “sooner or later,” Biden said.Biden urged Americans to get vaccinated, including those who are now eligible for the booster, and to continue to wear masks indoors.“We’ll fight this variant with scientific and knowledgeable actions and speed — not chaos and confusion,” Biden said. “We have more tools today to fight the variant than we ever had before, from vaccines to boosters to vaccines for children.”Once omicron gets to the U.S., it will likely “spread widely,” Dr. Anthony Fauci, the U.S. government’s top infectious diseases expert, told ABC News’ George Stephanopoulos in an interview Monday on “Good Morning America.”“It’s inevitable that, sooner or later, it’s going to spread widely because it has at least the molecular characteristics of being highly transmissible,” Fauci said.ABC News’ Aaron Katersky, Brian Hartman and Arielle Mitropoulos contributed to this report.Copyright © 2021, ABC Audio.
