Why are coronavirus cases and hospitalizations on the rise in the US?

With coronavirus infection rates back on the rise, many Americans are wondering why the U.S. is, once again, experiencing surge in cases and hospitalizations, despite widespread vaccinations. The U.S. is now reporting more than 94,000 new COVID-19 cases each day — up by 47% since late October. Experts say a confluence of factors is likely driving the country’s recent increases in infections, including the more than 100 million Americans who remain completely unvaccinated, cold weather and relaxed restrictions, the highly transmissible delta variant, and waning vaccine immunity.
