Study Finds Meningitis Kills About 250,000 People Annually

An estimated 259,000 people die from meningitis each year worldwide, according to a large new study released after the disease sparked fresh concern in the UK.

The research found that children made up roughly a third of those deaths, with many occurring in Africa—an outcome the authors described as the most extensive global assessment of meningitis to date.

The new findings arrive after meningitis was thrust into the spotlight following an outbreak in southeast England believed to have spread through a nightclub earlier this month, where two people died.

Meningitis refers to inflammation of the tissues surrounding the brain and spinal cord, triggered by infections from a range of pathogens, including viruses, bacteria, fungi and parasites.

In England, it was a bacterial infection outbreak in Kent that led to rapid public health action, with more than 10,000 people in the county vaccinated over the past two weeks.

Since vaccines became widely available, the global number of meningitis cases and deaths has declined, according to existing evidence. However, the latest study warns that progress is uneven—and in some places, vulnerable groups remain at significant risk.

Targets in danger of being missed

Even with vaccination efforts underway, the study estimates 259,000 deaths from meningitis worldwide in 2023. It attributes the highest burden of cases to the “African meningitis belt,” a region stretching from Senegal across to Ethiopia.

Nigeria, Chad and Niger recorded particularly high rates, the analysis said.

The researchers identified low birthweight, premature birth and air pollution as the biggest risk factors linked to the disease. They also cautioned that the World Health Organization is unlikely to meet its 2030 meningitis targets.

The WHO aims to cut bacterial meningitis cases worldwide by 50 percent and reduce deaths by 70 percent from 2015 levels by the end of the decade. But the study concluded that deaths and cases are falling at only about half the pace required to hit those goals.

“Accelerated efforts – including expanding immunisation, improving access to care, and strengthening diagnostics and surveillance – are essential to achieve these targets,” the authors said.

While many meningitis deaths never make it into official records—especially in low-resource settings—the researchers noted that incomplete reporting could mean some figures are underestimated.

The study draws on data from the Global Burden of Disease project run by the US-based Institute for Health Metrics and Evaluation, which compiles inputs from thousands of researchers worldwide and is funded by the Bill and Melinda Gates Foundation.
