The infant, known only by the pseudonym Asha, Nepalese for "hope", has humanised hundreds of anonymous asylum seekers who are faced with deportation from Australia to a detention camp on the South Pacific island of Nauru. The outpouring of public support, including an overnight blockade at a Brisbane hospital where she was treated for severe burns, has been likened by some to the shocking images last year of a young Syrian asylum seeker dead on a Greek beach.
