The rise of antibiotic-resistant bacteria is sounding alarm bells across the globe, casting a shadow over the future of healthcare. Experts are warning that common infections could once again become life-threatening as bacteria evolve at an alarming rate, outpacing our ability to develop new treatments. This concerning trend underscores a critical point: the unwavering adherence to evidence-based medicine is not just best practice, but a necessity in safeguarding public health.
Over the past decade, researchers in the UK have made a disturbing discovery – 19 new ways bacteria are developing resistance to antibiotics. This genetic arms race allows bacteria to shrug off even the most powerful “last resort” antibiotics, including carbapenems and colistin, once relied upon to combat the most stubborn infections.

The emergence of antibiotic-resistant gonorrhoea in 2016 served as a stark reminder of this escalating crisis. This particular strain presented significant treatment challenges, highlighting the speed at which bacteria can adapt and overcome medical interventions. Simultaneously, the UK has witnessed the arrival of at least 12 new diseases and infections, many carried across borders by international travelers. These include well-known threats like swine flu, Ebola, and Zika virus, alongside lesser-known but equally concerning illnesses such as Rift Valley fever, Middle East Respiratory Syndrome (MERS), and Monkeypox.
This convergence of increasing antimicrobial resistance and the emergence of novel infectious diseases creates a perfect storm, jeopardizing our ability to effectively treat patients. The annual death toll attributed to antibiotic resistance in the UK already stands at 2,200, and this number is projected to climb if current trends continue.
“Infectious diseases are constantly evolving. Bacteria are in an evolutionary battle with antibiotics, perpetually finding new ways to evade their effects,” explains Sharon Peacock, Director of Public Health England’s (PHE) national infection service. This relentless evolution underscores the importance of evidence-based strategies in infection control and antibiotic stewardship. Over-reliance or misuse of antibiotics, sometimes due to deviations from evidence-based prescription practices, can accelerate the development of resistance.
PHE’s strategic plan to combat infectious diseases over the next five years emphasizes the need for improved identification and control measures within the NHS. A significant concern is the potential for globalization and antimicrobial resistance to converge, leading to a global pandemic caused by an unknown pathogen – the dreaded “Disease X” scenario.

Professor Chris Witty, the government’s chief scientific advisor, warns, “Despite the advancements in vaccines and antimicrobials, infectious diseases remain a significant threat to public health. We are continually encountering new threats, and antimicrobial resistance is on the rise.” This reinforces the need for healthcare professionals to consistently adopt and advocate for evidence-based practices in their daily work to mitigate these threats effectively.
PHE has identified 32 “pan-drug resistant bacteria” in the last five years – bacteria that defy all available antibiotics. Adding to these concerns, scientists recently identified a new strain of group A streptococcus bacteria, potentially responsible for the surge in scarlet fever and throat infections among children since 2016. In severe cases, this infection can lead to sepsis or toxic shock syndrome.
Professor Dame Sally Davies, Chief Medical Officer for England, has issued a stark warning: rising antibiotic resistance threatens to reverse medical progress, potentially plunging us “back into the dark ages” where simple infections become deadly. She emphasizes that failing to address this crisis could result in significantly higher mortality rates.
Official figures paint a grim picture. In 2015, the UK recorded nearly 53,000 antibiotic-resistant infections, resulting in over 2,100 deaths. Furthermore, antibiotic-resistant infections accounted for almost 80 disability-adjusted life years per 100,000 people in England, highlighting the long-term health burden imposed by these infections. Among European nations, the UK ranks 13th in terms of disability-adjusted life years lost to antibiotic resistance, indicating a substantial public health challenge.
PHE also highlights other significant health threats for the coming years, including pandemic influenza, declining vaccination rates, and health inequalities. Celia Ingham Clark, NHS England’s Medical Director for Clinical Effectiveness, emphasizes the NHS’s commitment to reducing antibiotic use by a further 15% as part of its long-term plan. This initiative aims to preserve the effectiveness of antibiotics for future generations, encouraging the adoption of new, evidence-based treatment approaches and minimizing unnecessary antibiotic prescriptions.
In conclusion, the growing threat of antibiotic resistance demands a united and evidence-driven approach. While scientific advancements are crucial, the consistent application of evidence-based medicine in prescribing practices and infection control is equally vital. Only through a steadfast commitment to these principles can we hope to stem the tide of antimicrobial resistance and protect the future of public health.
