Superbug Crisis Could Lead to Nearly 40 Million Deaths by 2050, New Study Projects
A new study has raised the alarm about the growing antimicrobial resistance (AMR) crisis, predicting that the number of deaths caused by drug-resistant infections could increase by nearly 70% by 2050.
According to the study, which was published in The Lancet, the world could see more than 39 million deaths directly attributable to Superbug Crisis between 2025 and 2050.
The World Health Organization (WHO) has identified AMR as one of the top global public health threats.
The misuse and overuse of antimicrobial medications in humans, animals, and plants have allowed pathogens to evolve and resist treatments. This study offers a grim forecast of the future unless significant action is taken.
Alarming Trends: Older Adults Bear the Brunt of AMR
The study, conducted by researchers from the Global Research on Antimicrobial Resistance Project and the Institute for Health Metrics and Evaluation (IHME), analyzed data from 1990 to 2021.
The research highlighted a significant shift in AMR-related deaths across age groups.
From 1990 to 2021, deaths due to AMR fell by over 50% among children under five, a decrease attributed to vaccination programs, improved sanitation, and access to healthcare.
However, AMR deaths among adults 70 and older increased by over 80%, a trend that is expected to continue as the global population ages.
“We had these two opposite trends going on: success in reducing childhood deaths but a steady rise in older adults,” said Dr. Chris Murray, lead author of the study and director of IHME.
“Older adults are more vulnerable to severe infections, and this demographic shift underscores the urgency of tackling antibiotic resistance.”
One of the key pathogens responsible for the rise in AMR-related deaths is methicillin-resistant Staphylococcus aureus (MRSA).
The study found that deaths attributable to MRSA nearly doubled from 57,200 in 1990 to 130,000 in 2021. This alarming trend highlights the growing danger of drug-resistant bacteria.

Projections for 2050: The Cost of Inaction
The study presents three potential scenarios for AMR-related deaths by 2050.
In a status quo scenario, where no significant changes are made to improve healthcare access or develop new antibiotics, the number of global deaths attributable to AMR could reach 1.9 million annually, with associated deaths climbing to 8.2 million.
However, if the world were to invest in new antibiotics and improve access to quality healthcare, the study estimates that 92 million cumulative deaths could be averted by 2050.
Additionally, the development of potent new antimicrobial drugs could prevent around 11 million deaths during the same period.
The regions most affected by AMR are projected to be South Asia, Latin America, and sub-Saharan Africa, where access to quality healthcare is often limited.
Many people in these regions lack access to basic treatments, and in low-resource settings, even essentials like oxygen can be scarce.

Global Solutions: Hope on the Horizon
Despite the bleak projections, there is optimism about the potential to reduce the burden of AMR.
According to Dr. Steffanie Strathdee, associate dean of global health sciences at the University of California San Diego School of Medicine, the key to mitigating the crisis lies in scaling up interventions such as phage therapy, which saved her husband’s life after a superbug infection.
“Phage therapy can be an effective alternative to antibiotics,” Strathdee said. “It can help reduce the use of antibiotics in humans and animals and offer a solution to resistant bacterial infections.”
The study calls for a global commitment to improving access to healthcare, antibiotics, and vaccines, while also reducing the misuse of antimicrobial medications in livestock, food production, and the environment.
Such actions could dramatically decrease the number of deaths from drug-resistant infections in the future.
A Call for Immediate Action for Superbug Crisis
The new study paints a sobering picture of the superbug crisis and its potential to worsen without significant intervention. However, there is hope on the horizon.
By investing in new drugs, improving healthcare access, and promoting antibiotic stewardship, millions of lives could be saved by 2050.
The global health community must act now to prevent this looming catastrophe.
