WATCH: CNN's Brianna Keilar tears up talking about 500,000 Americans who lost their lives to COVID-19

CNN host Brianna Keilar on Monday got emotional when discussing the 500,000 Americans who have lost their lives to the novel coronavirus.

After showing videos telling stories of Americans who had lost loved ones to the disease, Keilar gave an impassioned monologue urging people not to become numb to the toll the virus has taken over the last year.

"I know that these stories of our fellow Americans puncture that armor that is natural to have accumulated over the past year, and that's okay," she said. "We need to remember the people that we have lost even if we didn't know them personally."

Keilar then recounted the sacrifices that so many have made over the last year, and not just those who have contracted the virus.

"I know it is hard," she said. "I hear it from so many of you. I know you're tired, I know you're tapped out. It has been more than a year since the first reported coronavirus case. The quarantining, the hoping that this would subside only to realize that it wouldn't any time soon, the struggling to make ends meet... you are not alone."
