“You can be sure that he is in the very best of hands and that we are doing everything humanly possible to help him,” the statement read.
“Please understand if we are following Michael’s wishes and keeping such a sensitive subject as health, as it has always been, in privacy," it continued.
"At the same time we say thank you very much for your friendship and wish you a healthy and happy year 2019."
The statement also announced that the official Michael Schumacher app will be launched this week so fans can celebrate the successes of his career.
“The app is another milestone in our effort to do justice to him and you, his fans, by celebrating his accomplishments,” the family said.
“Michael can be proud of what he has achieved, and so are we… we want to remember and celebrate his victories, his records and his jubilation.”
The Schumacher family rarely comment on Michael's health. It is believed he is being cared for by doctors near Lake Geneva in Switzerland.
