The Cuomo family has another member who's come down with COVID-19.

On Wednesday, Cristina Cuomo shared a photo of her son 14-year-old son, Mario, with husband Chris Cuomo to Instagram, commemorating Earth Day and revealing that their child has become infected with coronavirus.

Cristina, who was also diagnosed with COVID-19 and been battling the disease for the past 10 days, said she's currently working to help her son through it as well.

"This virus has created a different version of me. My hope is to be stronger, healthier, smarter about the virus at large. After 10 days of ups and downs, feeling good one-day and terrible the next, I am now working hard to get my son, Mario, through the virus," Cristina wrote.

She noted her heart hurts for her son and even though kids are "more resilient" when diagnosed with COVID-19, it still affects them severely.

"This virus does not discriminate. While kids are more resilient, they can suffer same severity of symptoms. I’m applying a modified version of my remedies for his protocol with a focus on lots of vitamins," Cristina wrote.

"Since his sense of smell and taste have disappeared, I am feeding him healthy foods that I normally can’t get him to touch. I kept a diary of the past week including my remedies and things that I did to stay sane through it all," she continued, sharing a link to her website.

Cristina Cuomo's post was timed to Earth Day. "On this 50th anniversary of Earth Day, show kindness toward our planet and every creature who inhabits it, as the transcendent photographer, adventurer, preservationist and raconteur Peter Beard advised us," she wrote. "My old friend’s recent death offers an eerily timely punctuation on this virus and a reminder that we can’t forget to protect one another, and the animals that roam the Earth."

Both Cristina and Chris Cuomo have been battling COVID-19. While the CNN anchor has finally emerged from quarantining in his basement, Cristina is still experiencing symptoms.

"I feel pretty good today," she told Entertainment Tonight on Friday.

Cristina said her symptoms started around Day 18 of her husband's coronavirus diagnosis.

"I was highly congested, had a terrible sinus headache, and I just thought, 'You know what, I'm so run down. I'm not getting enough sleep, I'm feeling a lot of stress from caregiving and managing the kids and my own business that it just caught up with me,' " she said.

Chris Cuomo revealed more details about he and his wife's COVID-19 diagnosis in a conversation Thursday night with Anderson Cooper and Dr. Sanjay Gupta on his show, "Cuomo Prime Time."

"This was tough for Cristina to get it," Cuomo said. "We have a lot of fear because we don't have a lot of facts."

He said that they have "completely different symptoms."

"She's stronger than I am. She's got a stronger immune system, a stronger constitution and a stronger character," Cuomo said.
