The U.S. reached 800,000 COVID-19 deaths Tuesday, and health experts believe there is "no question" the nation will reach 1 million fatalities from the coronavirus. "At the current trajectory we may reach it much sooner than expected, with cases, hospitalizations and deaths significantly increasing in the past two months," said Robert Glatter, an emergency medicine physician at Lenox Hill Hospital in New York City. Though such a death toll may be inevitable, but "we can still do a lot within our means to prevent that from happening," said Ogbonnaya Omenka, an assistant professor and director of diversity at the Butler University College of Pharmacy and Health Sciences. Both Glatter and Omenka emphasized that vaccinations and booster shots are still critical. But experts cringe at what the winter could bring as a surge from the delta variant continues to flare and the threat of omicron remains uncertain.
