The World Health Organisation (WHO) has published a report with data reported by 87 countries in 2020 warning of increasing antibiotic resistance in bacterial infections in humans. The report shows resistance levels of more than 50 % in bacteria that frequently cause bloodstream infections in hospitals, such as Klebsiella pneumoniae and Acinetobacter spp. 

Bacterial infections were the second leading cause of death in 2019. This is according to research published in The Lancet, which estimates that one in eight deaths that year was associated with bacterial pathogens. Five of these - S. aureus, E. coli, S. pneumoniae, K. pneumoniae and P. aeruginosa - accounted for more than half of all bacteria-related deaths.
