By 2050, nearly 39 million people are projected to die from infections that no longer respond to medication due to antibiotic resistance, according to a study recently published in the British medical journal, The Lancet.
Researchers predict a 70% increase in deaths from these unstoppable infections from 2022 to 2050, with the elderly most vulnerable. Antimicrobial resistance (AMR) develops when bacteria and fungi evolve, rendering existing medications ineffective.
A closer look at the data
The study, led by a team of global researchers, examined over 520 million records. This included hospital information, insurance claims, and death certificates from 204 countries. Their findings indicate a consistent rise in antimicrobial resistance (AMR) deaths, exceeding one million annually between 1990 and 2021.
Kevin Ikuta, an assistant professor of clinical medicine at the University of California, Los Angeles (UCLA) and a lead author of the study, emphasized the severity of the situation by noting that about three people could die every minute from these infections.
Improvements and challenges in different age groups
While AMR fatalities among children under five have declined by more than 50% since 1990, deaths among seniors over 70 have surged by over 80%. This trend indicates that while some progress has been made, the increasing lifespan of the global population is likely to cause a spike in AMR deaths among the elderly.
The burden of AMR is not distributed evenly across the globe. About 30% of the projected deaths, amounting to 11.8 million, are expected to occur in South Asia. However, Sub-Saharan Africa is also facing significant challenges. Researchers stress that as populations age, AMR deaths in older adults may soon outpace those in other groups.
Researchers also emphasized the importance of antibiotic stewardship in addressing this crisis. Ishani Ganguli, a primary care physician and associate professor of medicine at Harvard Medical School, exemplifies this approach by carefully evaluating when to prescribe antibiotics.
She focuses on educating patients about the ineffectiveness of antibiotics for viral infections like the common cold. She also suggests alternative treatments such as saltwater gargles and humidifiers.
Prevention and global action to fight AMR
In addition to promoting responsible antibiotic use, researchers advocate for broader infection prevention strategies. This includes improving access to clean water, enhancing vaccination coverage, and developing new antibiotics.
Christopher J. L. Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington and a senior author on the study, calls for a coordinated global effort, stating, “You can’t do this piecemeal. You really need a concerted global effort.”
The fight against AMR requires not just awareness but action from all sectors of society, including healthcare providers, governments, and individuals.
