Margaret Chan believes that she has become a 'modern Robin Hood' while liaising with rich and poor countries to make sure the world is prepared for a bird flu pandemic. Dr Chan said the WHO's role lay in co-ordinating the efforts of governments and organisations in the battle against the disease. 'We have to liaise with different countries and appeal to the wealthy to help the poor. Sometimes, these involve political issues and are rather sensitive,' she said. 'I feel like being a Robin Hood. 'A flu pandemic is an international event and no single institute has the ability to cope with it. 'All governments should have an open and sharing attitude. We encourage sharing of [influenza virus] samples for research purposes,' Dr Chan said. Appointed in June as the WHO's top official on infectious diseases, Dr Chan said she enjoyed her job very much. 'It is the area of work in which I have a lot of passion, and I am so glad that I have a chance to contribute,' she said. Based in Geneva and flying frequently to Asia, Dr Chan said she looks forward to visiting friends and former colleagues. 'I miss Hong Kong. I hope that I can spend one or two days in Hong Kong in the middle of my trips.'
