Meningitis Prevalence in the UK

The overall incidence of meningitis in the UK is approximately 1.5-1.6 cases per 100,000 population annually, with bacterial meningitis accounting for 1.05-1.49 per 100,000 and viral meningitis representing 2.73 per 100,000 in adults. 1, 2, 3

Overall Epidemiology

The UK Joint Specialist Societies guideline reports that meningitis incidence has remained relatively stable in recent years, though this masks important age-specific and pathogen-specific trends 1. The disease is notifiable in the UK but is widely believed to be underreported, meaning actual prevalence may be higher than surveillance data suggests 1.

Bacterial Meningitis Rates

  • Adult incidence: 1.05 cases per 100,000 population (data from 2004-2011 in England and Wales) 1
  • Overall bacterial meningitis: Mean annual incidence of 1.49 per 100,000 during 2012-2019, which remained stable throughout this period 2
  • Highest risk age group: Adults aged 45-64 years had the highest incidence at 1.21 per 100,000 1
  • Elderly population: Increasing incidence in those over 65 years, with a 3% annual increase between 2004-2011 1

Viral Meningitis Rates

  • Adult incidence: 2.73 per 100,000 annually, making viruses the most commonly identified cause of meningitis in UK adults 3
  • Pre-pandemic trends (2013-2019): Gradual increase from 3.5 per 100,000 to 3.9 per 100,000 4
  • Post-pandemic (2022-2023): Incidence increased to 4.2 per 100,000 after societal restrictions were lifted 4

Age-Specific Patterns

Infants under 3 months have dramatically higher rates than any other age group:

  • Bacterial meningitis: 55.6 per 100,000 (primarily group B streptococcus) 2
  • Viral meningitis: 504 per 100,000 pre-pandemic, with enteroviruses causing 84.9% of cases 4

Young adults (16-25 years) experience a second peak, particularly for meningococcal disease 1. Viral meningitis is more common than bacterial in this age group, especially in women aged 20s-40s 1

Meningococcal Disease Trends

Invasive meningococcal disease (including meningitis and sepsis) has declined substantially over the past decade following introduction of the group C vaccine 1:

  • Decreased from 1.93 per 100,000 in 2010-11 to 0.74 per 100,000 in 2019-20 5
  • During COVID-19 lockdown (April-August 2020), incidence was 75% lower than the same period in 2019 5

Key Pathogen Distribution

Among bacterial causes (excluding coagulase-negative staphylococci), the main pathogens are 2:

  • Streptococcus pneumoniae: 19.9% of cases
  • Neisseria meningitidis: 12.2% of cases
  • Staphylococcus aureus: 11.5% of cases
  • Escherichia coli: 7.7% of cases
  • Group B streptococcus: 6.6% of cases

Clinical Significance

The mortality rate remains substantial: approximately 20% for all-cause bacterial meningitis and up to 30% for pneumococcal meningitis, with rates increasing with age 1. The 30-day case-fatality rate across all bacterial meningitis was 10.0% during 2012-2019 2.

Patients with viral meningitis experience a mean loss of 0.2 quality-adjusted life-years in the first year after infection compared to the age-matched UK population, indicating substantial long-term morbidity 3.
