Unable to hold back her tears, Ms Sidner spoke about how the woman's family was forced to hold a funeral for their loved ones in a auto park.
After showing a clip of health workers detailing what they have to deal with on a daily basis, as well as bereft family members, Sidner returned to talk with host Camerota and promptly burst into tears - having to pause and ask for forgiveness as she described what it has been like for her to talk to families dealing with the death of their loved ones.
Kicking off her coverage on CNN's New Day, Sidner noted the "unconscionable" fact that one person is dying every eight minutes in the nation's second-largest city, and that Black and Latino communities are getting hit the hardest.
Wrapping up her report, Sara says, "To see the way that these families have to live after this and the heartache that goes so far and so wide, it's really hard to take".
This video sends a powerful message to everyone.
"Don't let this be you", Sesma said.
The United States continues its losing fight against a virus that has infected more than 90 million people worldwide and killed nearly two million.
Wiping her tears away, Sidner responded: "It's just not OK".
"It's just not OK, it's not OK what we're doing to each other", Sidner said elsewhere in the segment, adding a call for people to do their part in helping to stop the spread of the virus. "These families should not be going through this, no family should be going through this".
"I'm okay. I've been hit with much worse in my day", she told him. "No family should be going through this", Ms Sidner said.
As the USA reaches 376,000 deaths due to coronavirus, the reporter's display of vulnerability was met with praise by social media users and fellow journalists alike. "The tears, including your own, are totally justified", wrote one Twitter user. Jimenez Sesma was forced to hold a funeral service for her mother in a parking lot because funeral homes in the state are overwhelmed due to rising coronavirus deaths.
