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.

New York's daily positivity rate stands at 5.41%.

New York has the fourth-lowest infection rate in the country behind Maine, Vermont and Hawaii.

Over 70% of cases are coming from small gatherings, Cuomo said, and he called on local governments to enforce restrictions.

Cuomo said that the focus should be on the hospitalization rate rather than the infection rate.
