New COVID-19 cases plummet to lowest levels since last June

New coronavirus cases across the United States have tumbled to rates not seen in more than 11 months, sparking optimism that vaccination campaigns are stemming both severe COVID-19 cases and the spread of the virus.

As cases, hospitalizations and deaths steadily dropped this week, pre-pandemic life in America has largely resumed. Hugs and unmasked crowds returned to the White House, a Mardi Gras-style parade marched through Alabama's port city of Mobile, and even states that have stuck to pandemic-related restrictions readied to drop them. However, health experts also cautioned that not enough Americans have been vaccinated to completely extinguish the virus, leaving the potential for new variants that could extend the pandemic.
