Zach Braff shared a post reflecting on the way his late friend Nick Cordero might have contracted COVID-19.
"I couldn't fall asleep last night thinking that Nick may have gotten Covid from someone in New York City not wearing a mask who had it, but had no symptoms, so didn't even know they had it," the actor wrote Thursday alongside a photo of Cordero with his 1-year-old son, Elvis.

"Wearing a mask isn't just for your own health; it's for all the people who could get sick if you're carrying it and don't even know," Braff wrote in his post. "Somewhere out there, there is perchance a person who caused this tragedy and will never know. Anyway, that's what kept me up. Nick loved being a Dad."
Cordero had been on a ventilator in a Los Angeles hospital since early April after going to the emergency room for what he thought was pneumonia.
While hospitalized, he suffered from multiple infections, sustained lung damage, spent time in a medically induced coma and required a leg amputation, among other health issues. He died on July 5, 2020.
On the day of Cordero's passing, Braff shared an emotional tribute, saying he's "never known a kinder person" than the Broadway star.
"The last thing he ever texted me was to look out for his wife and one year old son, Elvis," Braff wrote alongside a photo of Cordero and Kloots. "I promise the world they will never want for anything. I feel so incredibly grateful I got to have Nick Cordero enter my life."
