A rare and severe outbreak of Invasive Meningococcal Disease has recently emerged in Kent, UK, with the situation rapidly worsening and drawing significant attention from local and international communities. According to the UK Health Security Agency (UKHSA) and multiple media reports, as of March 17, 15 related cases have been confirmed. Sadly, two people have died, including a 21-year-old university student and an 18-year-old secondary school student, with another 13 hospitalized.
Meningitis B Identified as the Cause of the Outbreak
Four of the confirmed cases have been attributed to Meningococcal B (MenB) bacteria. This bacteria can spread rapidly through close contact, progresses quickly, and has a fatality rate of approximately 10%.
What is Meningitis?
Meningitis is an inflammation of the protective membranes covering the brain and spinal cord, usually caused by bacterial or viral infection. Bacterial meningitis (such as the MenB strain in this outbreak) is rarer but progresses extremely rapidly, worsening within hours. Severe cases can lead to sepsis (blood poisoning), brain damage, and even death. The bacteria can be transmitted through respiratory droplets from carriers or patients, or through close contact (such as kissing or sharing items). Therefore, environments with frequent interpersonal interaction (like university dormitories or nightclubs) carry a higher risk.
Quick Guide to Meningitis Symptoms: Don't Confuse with Common Cold or Hangover
Meningococcal disease can deteriorate rapidly within a short time. Early symptoms are often similar to those of a cold, flu, or hangover and can be easily overlooked. UK health officials specifically remind that if any of the following symptoms appear, seek medical attention immediately:
- High fever
- Severe headache
- Stiff neck
- Vomiting, diarrhoea
- Dislike of bright lights
- Drowsiness, difficulty waking, or confusion
- Cold hands and feet
- A rash that does not fade when pressure is applied
Important Risk Information for Hong Kong Residents: Meningitis Vaccines Not Included in Hong Kong's Childhood Immunisation Programme – Assess Your Needs Before Travelling to the UK
In the UK, the MenB vaccine has been part of the routine childhood immunisation programme since 2015. However, most adolescents and adults over the age of 10 have not received it and therefore lack immunity to this current outbreak.
For individuals born and raised in Hong Kong, it is crucial to note: the Hong Kong Childhood Immunisation Programme currently does not include routine meningococcal vaccines (neither MenACWY nor MenB vaccines). This means the vast majority of students, young people, or travellers from Hong Kong heading to the UK may have absolutely no relevant antibodies and lack immunity to the MenB strain currently circulating in the UK.
Therefore, for those planning to travel to the UK, especially students, it is essential to consult a travel health centre before departure and consider the need for meningococcal vaccination (including both MenACWY and MenB vaccines).
