Healthcare experts are raising alarms over the growing threat of antimicrobial resistance (AMR), warning that it is placing a significant burden on patients and healthcare systems worldwide. AMR occurs when microorganisms such as bacteria, viruses, fungi, and parasites evolve to resist medications, making infections more difficult to treat and increasing the risk of severe illness, disease spread, and death.
According to the World Health Organization (WHO), AMR renders treatments such as antibiotics, antivirals, antifungals, and antiparasitics less effective, allowing infections to persist in the body and potentially spread to others. These resistant microorganisms are often referred to as “superbugs.”
The global impact of AMR is staggering. In 2019, bacterial AMR was directly responsible for 1.27 million deaths globally and contributed to 4.95 million deaths, according to United Nations estimates. The World Bank has warned that AMR could result in up to $1 trillion in additional healthcare costs annually by 2050 and cause significant economic losses, ranging from $1 trillion to $3.4 trillion in gross domestic product (GDP) per year by 2030.
The challenge of AMR is especially severe in Africa, which bears a high burden of infectious diseases. A report from the Africa Centres for Disease Control and Prevention (Africa CDC) revealed that the continent faces the highest mortality rate from antimicrobial resistance globally, with 27.3 deaths per 100,000 people—surpassing the combined death toll from HIV/AIDS, tuberculosis, and malaria. Vulnerable groups such as children are most at risk.
“Africa accounts for 95% of malaria deaths, 70% of people living with HIV, and 25% of global TB deaths. The continent is facing an escalating crisis with AMR,” the report stated.
Medical virologist and immunologist Dr. Oladipo Kolawole from Adeleke University, Osun State, explained that the consequences of AMR are far-reaching. “AMR leads to ineffective treatments, prolonged illness, higher healthcare costs, and a greater risk of severe outcomes or death,” Dr. Kolawole said in an interview.
He added that drug-resistant infections often require longer hospital stays and more intensive care, placing a heavy financial burden on healthcare systems. “Treating drug-resistant infections is more expensive, and patients face higher risks of complications. Infections that were once easily treatable, like pneumonia and tuberculosis, are now becoming life-threatening,” he said.
Professor Tanimola Akande, a public health expert at the University of Ilorin, emphasized that AMR undermines the effectiveness of medical treatments, including surgeries, cancer therapies, and organ transplants. “AMR can reverse decades of progress in medicine. It threatens the very foundation of healthcare as we know it,” he warned.
Both experts called for urgent action to combat AMR, stressing the need for better antibiotic stewardship, the development of new treatments, and stronger global health systems. “AMR does not recognize borders, and addressing it requires coordinated international efforts, including surveillance, research, and the development of new treatments,” Dr. Kolawole concluded.
As the threat of AMR continues to grow, healthcare systems around the world face the challenge of keeping pace with the evolving resistance of microorganisms, underscoring the urgent need for global collaboration to prevent a future health crisis.
