Global Burden of Diseasepublic health

Highlights

  • Lower respiratory infections (LRIs) resulted in 2.50 million deaths and 98.7 million DALYs globally in 2023, remaining the leading infectious cause of mortality.
  • Mortality among children younger than 5 years decreased by 33.4% since 2010, yet 129 of 204 countries have met the GAPPD target of fewer than 60 deaths per 100,000.
  • Streptococcus pneumoniae remains the leading LRI pathogen, responsible for 25.3% of all LRI deaths.
  • The inclusion of 11 newly modelled pathogens, including non-tuberculous mycobacteria and Aspergillus spp, accounts for approximately 22% of the global LRI death toll.
