Some cases of meningitis in Kent have been confirmed as meningitis B, the UK Health Security Agency (UKHSA) told the Press Association, adding it will confirm the other cases "when we have the full results".

The government agency said it was continuing to investigate the outbreak, which has been linked to a nightclub in the southeast England region and killed two students.

Hundreds of people who visited Club Chemistry in Canterbury on March 5, 6 or 7 have been urged to come forward for preventative antibiotic treatment as a "precautionary measure".

The UKHSA said on Monday evening it had been notified of 13 cases since March 13, including the deaths of a sixth form pupil from Faversham and a student at the University of Kent.

Young people born before 2015 are not protected against meningitis B, which was introduced on the NHS for babies 11 years ago, unless they have received the jab privately.
