Bacterial alert: Centre for Health Protection Controller Dr Thomas Tsang urges the public to ensure personal hygiene and avoid inappropriate use of antibiotics.

The Hospital Authority will strengthen surveillance to prevent the spread of a drug-resistant bacterium containing the NDM-1 gene.

Centre for Health Protection Controller Dr Thomas Tsang told the media today he is concerned about the 'superbug', as the gene is resistant to some of the most powerful antibiotics. However, he assured patients infected with bacteria carrying the gene can be cured.

Last October a 66-year-old man was found to be infected with E.coli harbouring NDM-1. He recovered after taking an oral antibiotic usually used to treat urinary tract infection.

Dr Tsang warned there may be more cases in future and urged the public to stay vigilant, watch their personal hygiene and avoid inappropriate use of antibiotics.

He said the centre's microbiologist expert group will meet soon to evaluate the situation and establish long-term policies in combating the spread of the drug-resistant infections.

The current surveillance system for methicillin-resistant S.aureus will be strengthened to cover other drug-resistant bacteria, while additional laboratory support will be offered to private hospitals and clinics.

An anti-biotic stewardship programme has been launched by the Department of Health and the authority to monitor the prescription of antibiotics at public hospitals.

He said there are alternate treatments for drug-resistant bacteria but people should pay special attention to hand hygiene and follow doctors' instructions when given antibiotics. The centre will monitor the situation.
