The Kent meningitis outbreak: what is happening and why?
Why it matters: A familiar bacterial threat is resurfacing, but public health has the tools to contain it.
- Meningitis is a serious but uncommon disease, with the Kent outbreak specifically caused by the MenB strain of meningococcal bacteria, which has been extensively studied for centuries, according to Prof Sir Andrew Pollard.
- Meningococcal bacteria are carried by about 10% of the population in their nose and throat, with up to 25% carriage in student populations, spreading through close contact like kissing or sharing drinks, as highlighted by Dr Eliza Gil.
- Unlike COVID-19, which spreads easily through airborne particles, meningococcal bacteria require prolonged, close contact and do not survive well outside the body, making it much harder to transmit and contain, with widespread antibiotics and vaccinations expected to help control the outbreak.
Kent is experiencing a localized outbreak of MenB meningitis, a bacterial infection causing brain inflammation, which, while potentially lethal, is well-understood by public health officials unlike the novel challenges posed by COVID-19. This outbreak primarily affects vulnerable groups like babies, teenagers, and young adults due to their developing immune systems or social behaviors that facilitate close contact.
