An outbreak of invasive meningococcal disease B (MenB) has occurred in Kent, involving 18 confirmed cases, 13 of which are type B, plus 11 suspected cases, with two deaths. The UK Health Safety Agency (UKHSA) described it as unprecedented for the large number of cases in a short period of time.[1][3] Transmission of Neisseria meningitidis requires close contact via saliva or respiratory droplets from a carrier, which occurs in 10% of the population.[1] Before vaccination, the carriage rate was as high as 33% in adolescents with risk factors such as going to pubs or smoking.[1] Cases have been linked to young adults, including University of Kent students and visitors to the Canterbury Chemistry Club.[2][3] The UKHSA introduced a targeted Bexsero vaccination program for at-risk groups and preventive antibiotics for clubgoers and students.[1][2][3] The risk outside Kent remains low and all cases are so far localized to the region.[3][4]
