Updated at 7.18pm: The Health Department said on Thursday it was liaising closely with the World Health Organisation (WHO) and the Consulate General of Indonesia to obtain the latest information on the most recent outbreak of bird flu in the archipelago. Centre for Health Protection (CHP) acting consultant Chuang Shuk-kwan told reporters on Thursday the centre was maintaining close contact with the WHO and the Consulate General of Indonesia. The CHP was anxious to obtain more information on the situation in Indonesia. Four people have now died in Jakarta - including two children. Some 11 others have also been hospitalised with flu-like symptoms. Dr Chuang said the department's Port Health Office has arranged the broadcasting of health messages on board in-bound flights from Indonesia. Health information leaflets would also be distributed to passengers leaving for the country. 'To arouse awareness among Indonesians and other ethnic minorities in Hong Kong of the threat of avian influenza, Department of Health staff will send publicity pamphlets in eight languages to relevant organisations for distribution among the target population,' Dr Chuang said. The department planned to approach the target groups to provide direct health advice and answer enquiries. This was because radio programmes for the minorities was a channel to disseminate the health message, Dr Chuang said. 'The CHP is also sending letters to all doctors in Hong Kong updating them about the latest avian flu situation and to remind them to remain vigilant regarding the disease,' she said 'Doctors are required to notify any suspected case of avian influenza to the CHP for prompt investigation and control measures,' added Dr Chuang. The H5N1 strain of bird flu has swept through poultry populations in large swaths of Asia since 2003. It has killed at least 63 people and tens of millions of birds. In recent years, Hong Kong has also suffered serious outbreaks of the disease and fears continue in the territory that the disease could return. Most human cases have been linked to contact with sick birds. But the WTO has warned the virus could mutate into a form that spreads easily among humans - possibly triggering a global pandemic that could kill millions.
