U.K. pensioner Dorothy Wilson (right, photo from Chronicle Live) had to wait four weeks before medics identified the source of her ailment as E.coli in Dubai.

Chronicle Live reports that after medics repeatedly missed the bug, the pensioner had to be moved to a private hospital so she could get the treatment to save her life.

Doctors at the first hospital, where she had spent almost a month, in the United Arab Emirates, couldn’t work out what was wrong with her.

Charles Wilson, 75, has also thanked the private medics who came to their rescue when others had failed.
