The "Chrisley Knows Best" star revealed his diagnosis Wednesday, and said he's been battling COVID-19 for 3 weeks. He says his treatment required 4 days in the ER. Seems like he's back in decent spirits for a couple reasons: He was able to record his podcast, and referenced the virus by asking, "Can we talk about this bitch called corona?"

He went on to reveal he'd been battling high fevers -- from 100 to 103 degrees -- and added, "Hopefully, I will get better every day, but as of right now, folks, I still am not clicking on all cylinders. I am probably about 70 to 75% of what I normally am, but that last 25% is kicking my ass."

Todd's daughter Savannah opened up in great detail in an Instagram post saying, "I have never been so scared in my life ... After a couple of days mom and I talked him into going to urgent care."

Savannah said Todd was eventually tested and sent home to self-quarantine. But, the test came back positive a week later. As if things couldn't get any worse ... Savannah said Todd finally woke up one Sunday and "He woke mom up saying he has to go to ER [because] he couldn't fight it any longer."

Seems Todd's back on the mend, but Savannah urged her fans ... "The point of me telling u all this is so that u take it seriously...STAY HOME! SOCIAL DISTANCE! And most importantly...LOVE HARDER THAN EVER! Life is so short."
