The Centre for Health Protection (CHP) is following up with the health authority in the United Kingdom about an outbreak of invasive meningococcal disease in Kent, the UK.

The cluster involves at least 20 patients. Two of whom have died, and some of the cases were confirmed to be infected by Group B meningococcus.

Epidemiological investigations by the local health authority revealed that all those affected are young adults. Some visited a local nightclub called "Club Chemistry" between March 5 and 7.

The local health authority is conducting contact tracing and has provided preventive drugs to over 2,500 persons who visited the nightclub during the period and to those who were close contacts of the cases.

Since some of the patients are students at the University of Kent, the university has also collaborated with the UK health authority to provide health advice and conduct contact tracing among its staff and students, as well as offering vaccinations to students who reside in campus halls.

The CHP has enquired with the UK health authority whether any persons who visited the nightclub during the relevant period were students from Hong Kong. No notification has been received so far.

Hong Kong has recorded three cases this year so far. A total of 11 cases were recorded last year.

CHP reminds that with the Easter holidays approaching, overseas students may return to Hong Kong. He reminded members of the public to seek medical advice as soon as possible if they develop symptoms of meningococcal infection. Travellers should seek professional advice from doctors for meningococcal vaccination.
