Dmitriy is believed to have caught the virus during a trip to Turkey and was taken to hospital upon his arrival home in Ukraine where he tested positive.
Dmitriy updated his followers on his health last week, revealing it was his eighth day with the virus.
"As you all know from stories, I am sick with coronavirus. Today, after returning home, for the first time there was an enthusiasm for at least writing something. I want to share how I got sick and convincingly warn everyone: I also thought that there was no covid... Until I got sick,” he said.
"I felt bad on the second day in Turkey. I woke up in the middle of the night because my neck was swollen and it was hard to breathe. At the same time, my stomach ached a little."
"The next day, a cough began to appear, but there was no temperature. There were no particular symptoms of the disease either, so I thought that these could be consequences after playing sports, changing the climate and nutrition, and plus sleeping under air conditioning," he continued.
"After returning from Turkey, I immediately went to take various tests, do an ultrasound scan and, just in case, decided to take a COVID test. It turned out to be positive."
The influencer added: "They gave me an oxygen apparatus for breathing, since I have a low oxygen level (although I think it is considered critical after 90, for me 94-96 it is quite permissible for treatment at home, the doctor in the waiting room told me the same thing)."
He told his followers how the hospital was "completely filled with people, some of them being treated in corridors".
He was discharged from hospital after eight days, but suffered heart complications as a result of the virus.
Dmitriy was then rushed back to hospital, with his ex-wife Sofia Stuzhuk, 25, updating her followers that he was in a "grave condition" and "unconscious".
She added that he had "problems with his cardiovascular system... his heart is not coping".
"His state is extremely grave. No one can do anything with this.
"I did everything I could so the father of my three children lives. But nothing depends on me now,” she said.
She later confirmed his passing, saying: "Yes, we didn't have a good relationship. Yes, there were many problems. But this relationship gave us so much.
"We have lived and experienced so much with you. You were there in sorrow and in joy... I will remain grateful to you for the rest of my life for our three beautiful children."
"We were no longer together, but it hurts me no less," she continued. "I am so sorry... I'm sorry. Thank you for everything, my important person, my main teacher, my guide, the father of my children."
She finished by saying: "You are our guardian angel and your love will always protect our angels. How painful it is to realise... Blessed memory of you, Dima Stuzhuk."
