Colorado's first gentleman Marlon Reis, who was diagnosed with the coronavirus last week with his partner Gov. Jared Polis, was hospitalized Sunday after his condition worsened, the governor's office said.

Reis experienced a "slightly worsening cough and shortness of breath," on his eighth day of the virus, according to the governor's office.

Polis drove Reis in his own vehicle to the hospital, according to the governor's office.

"Governor Polis is not experiencing any additional symptoms at this time," the governor's office said in a statement.

The U.S. has hit another record level for coronavirus related hospitalizations, according to the COVID Tracking Project.

There are at least 101,487 Americans hospitalized as of Sunday evening, the tracking project tweeted.

There were over 176,000 new cases and 1,138 new deaths recorded Sunday, according to the health data.

The seven-day average for the tracking project's main metrics also saw new record highs. The seven-day average for new cases was 191,736, for deaths were 2,171 and hospitalizations were 99,939, according to the health data.

The U.S. has now reported over 100,000 cases every day for more than a month straight, and over 200,000 cases for the last three consecutive days, according to health data.

The country reported more than 1.3 million COVID-19 cases in the last week, which is more than any other week on record, the health data showed.

In the last month, the average number of daily cases has doubled. 

The U.S. is currently averaging over 186,793 new coronavirus cases every day, the highest the average has been since the beginning of the pandemic, according to health data.

Since last week, there have been nearly new 15,000 COVID-19 related deaths, with five days over the 2,000 mark, the health data showed.

That is roughly equivalent to 88 COVID-19 related deaths reported every hour. 

The U.S. is currently averaging 2,123 reported COVID-19 deaths a day, that average has increased by 142% since last month, according to the health data.

Hospitalizations continue to surge to unprecedented levels, with over 101,000 patients currently hospitalized with COVID-19 across the country, according to the health data.

Current hospitalizations have nearly doubled in the last month, the health data showed.

Los Angeles County set a new record number of coronavirus cases Sunday, the Health Department said.

The county saw 10,528 new cases and 23 new deaths, according to the Health Department. There are 2,855 people currently hospitalized, the Health Department said.

Los Angeles leads the country with total number of cases, 439,408, and total fatalities, 7,886, according to Johns Hopkins University's Coronavirus Resource Center.

More than 4.2 million people in the United States were diagnosed with COVID-19 in the month of November alone -- a figure that's higher than the total number of confirmed cases for every other country in the world except Brazil and India, according to data collected by Johns Hopkins University.

The number is roughly equivalent to one in every 76 Americans testing positive for COVID-19 in November, or 99 Americans testing positive every minute.

Throughout the month of November, the country saw a sharp increase in COVID-19 cases, recording more than 100,000 each day since Nov. 4 -- 27 straight days. At least 40 U.S. states and Puerto Rico reported a record number of daily cases in November.

The United States is currently averaging 158,000 new cases per day, a 96% increase in the country's seven-day average from the start of November. However, it's difficult to know exactly where the country stands given the data inconsistencies due to lags in reporting over Thanksgiving followed by backlogs from the holiday.

November also marked the deadliest month for COVID-19 in the United States since May, with 36,745 fatalities from the disease. The country currently accounts for 18.3% of the global death toll in the coronavirus pandemic. The nation's seven-day average of daily COVID-19 deaths has increased by nearly 80% since the beginning of November.

Last week, there were two days with over 2,000 new deaths reported nationwide -- the first time that threshold had been crossed on consecutive days since late April.

Meanwhile, more Americans are currently hospitalized with COVID-19 now than ever before. That figure topped 96,000 on Monday and is well on track to surpass 100,000 before the end of the week.

The number of COVID-19 patients hospitalized in western states is now the highest it's been since the beginning of the pandemic, while that figure is reaching near records in midwestern and southern states. In turn, states across the country are warning that hospital systems are on the brink of collapse.
