"I'll tell you what I know from the nanny cam and from videos, because I can't see him, which is the very worst part," he said on Sirius XM's "Jeff Lewis Live." "But he's great, and his nanny (tested) negative."
Cohen, 51, says he's being put through the ringer by the virus.
"I feel like it's definitely working its way through my body," he said.
"I have these moments every day where I'm like, 'Oh, wait, I think I feel totally better,' and then, like, 10 minutes later, I'm like, 'Ughhhh.'"
Cohen says he's also lost his sense of smell and hasn't had an appetite, resorting to foods like soup.

Despite his condition, Cohen has maintained his sense of humor, joking about how the loss of appetite will affect his body.
"Two days ago, before I went to bed, I took a shower and I was walking into the shower and I looked at myself and I was like, 'Holy crap, dude, you look good!'"
And while Lewis pointed out many people are eating a lot while they stay home, Cohen said he longs for the day he's hungry again.
"I saw a picture of a pizza somewhere and I was like, 'I can't wait to eat pizza,' and then I was thinking, 'God, when I get better, I am going to gain so much weight.' There's no question about it," he said.
