Meningococcal disease

Household crowding and second-hand smoke exposure increase the risk of meningococcal disease

Meningococcal disease is a serious infection which can cause meningitis (an infection of membranes that covers the brain), septicaemia (blood poisoning), and even death. Household crowding increases the risk of meningococcal disease, particularly in those aged 0–16 years [1]. Second-hand smoke exposure is also associated with an increased risk of meningococcal disease in children [2,3].

Meningococcal disease notifications halved in 2023

Meningococcal disease notifications among children aged 0–14 years have declined from 42 notifications (4.4 per 100,000) in 2022 to 21 notifications (2.2 per 100,000) in 2023. This decrease has been driven by a drop in the number of notifications among children under five years.

Meningococcal disease notifications

Source: EpiSurv notifications surveillance database, ESR.

Definition: Notifications of meningococcal disease in children aged 0–14 years. Notifications only cover those people who visited a GP or received hospital treatment, and therefore may underestimate the true rate of disease in the population.
