Joes right, years ago my mum and dad wanted to emigrate to Australia they had to pass a medical, but my mum failed the medical because of chest problems so therefor she was turned down that mean't the family had to stay in the UK, so it isn't racism to deny someone entry if they are suffering from an infectious disease it is common sense really, if the people who want any Tom Dick or Ali with an infectious disease to have the right to settle here had to pay compensation to anyone infected by these people they might have a different attitude.
