Shirlie Kemp posted on her Twitter account that:

George is doing well, been rather poorly but on the mend x

The Daily Mail is reporting:

A friend, though, insisted he was responding ‘well’ to treatment for the pneumonia.

‘He got ill, it’s very cold in that part of Europe, and then he got pneumonia. He’s responding well to treatment, very good. But he has to rest. He’s got to let this illness run its course.’

The Daily Mail also reported that George is being treated in Vienna and he is being cared for by medics in a private house.
