The United States logged 40 million COVID-19 cases since the start of the pandemic, as the fourth wave brought on by the delta variant continues to spread throughout the country.
The country has recorded 40,000,070 cases and 651,690 deaths, according to the latest NBC News tally. On Sunday, the U.S. recorded 35,355 news cases and 279 deaths.
The milestone comes as almost more than 207 million people have received their first dose and more than 175 million people have been fully vaccinated.
There has been a slow uptick in vaccination rates since July, but still no state or territory has passed the 70 percent fully vaccinated threshold among its population, and the country is nowhere close to its peak in April of more than 3 million people getting a shot each day.
The fourth wave, which many say could have been prevented with better vaccination rates, has overwhelmed hospitals.

At the same time, hospitals are also facing a nurse staffing crisis, as many nurses exhausted by the pandemic are quitting or retiring.
