Concerns were growing for the 48-year-old singer after he was admitted to intensive care in a Vienna hospital, but those in charge say he was admitted to the department because of the 'severity and extension' of the illness, although he is now on the mend.
In a statement to The Sun, Professors Gottfried Locker and Christoph Zielinski said, 'The latest development in Mr Michael's case, which has evolved from a severe pneumococcal infection, necessitated intensive care due to its severity and extension.
'We are happy to announce that Mr Michael is improving steadily with an impressive regression of pneumonic symptoms and follows a steady rate of improvement as hoped.
'There are no other health issues with regards to the patient other than the underlying pneumonic disorder, and no further measures had to be taken.'
They continued, 'Mr Michael is receiving precisely the same treatment as any ordinary patient in Austria would receive at the hospital for this disease.'
