The UK Health Security Agency said on March 19 that it is investigating an outbreak of invasive meningococcal disease in Kent that, as of March 18, was linked to 27 cases: 15 confirmed and 12 additional linked cases that have not all been laboratory confirmed. The agency said two people have died. The two deaths have been identified as an 18-year-old schoolgirl and a 21-year-old University of Kent student.
UKHSA’s formal statistical release classifies the 12 unconfirmed cases as probable. Nine of the 15 confirmed linked cases were confirmed meningococcal group B, or MenB, in the statistical release.
The public health response is centered on preventive antibiotics for people most likely to have had meaningful exposure. UKHSA said the drugs are being offered to University of Kent students, to people who visited Club Chemistry in Canterbury on March 5, 6 and 7, and to close contacts of confirmed or suspected cases. The agency said general practitioners across England can prescribe the treatment to people who were told to seek it and have since left Kent. Prime Minister Keir Starmer has urged anyone who attended Club Chemistry on those dates to come forward to receive antibiotics.
UKHSA also said a targeted MenB vaccination program has started for students and staff who live in or work in halls at the University of Kent’s Canterbury campus, covering about 5,000 students initially. To date, 600 MenB vaccines have been administered at the Canterbury campus after hundreds of students joined a queue outside the campus sports centre, and 6,500 antibiotics have also been given out as a precaution. The agency said the program could be expanded if risk assessments show other groups need it.
The agency said confirmed cases have been identified in students at four schools in Kent and in one student at a higher education institution in London who is directly linked to the Kent outbreak. UKHSA also said it is coordinating a national response, but stressed that this does not mean a national National Health Service (NHS) incident has been declared.
Kent County Council’s director of public health, Dr. Anjan Ghosh, told BBC Radio 4 that officials are not yet in a position to say definitively that the outbreak has been contained, noting they are still working to rule out secondary transmission.
For the wider public, UKHSA said the risk remains low and that transmission typically requires close and prolonged contact, such as living in the same household or intimate contact. Experts note the bacteria spread through respiratory droplets and saliva, particularly in settings with intense social mixing such as shared accommodation or crowded indoor venues. The agency has stressed that antibiotics remain the main measure for controlling the outbreak, while the MenB vaccine is meant to reduce the risk of severe illness in people who receive it. It does not protect against all strains of meningococcal disease, UKHSA said, and it does not stop the bacteria from being carried and spread in the community. The agency’s blog also notes that the MenACWY vaccine — which targets four other meningococcal strains and is routinely offered to teenagers — does not protect against MenB.
UKHSA’s statistical release says daily outbreak counts are verified at set times and may move up or down as cases are confirmed, reclassified or discarded. The agency said it will continue updating the figures as the Kent investigation remains ongoing.
