Antibiotic Resistance in the Post-COVID-19 Era: A New Dimension of Threat

Najeeb, Manar Saeb and Khursheed, Hussein Abbas and Mohammed, Faten Jassim and Khaleel, Alaa Mohammed (2025) Antibiotic Resistance in the Post-COVID-19 Era: A New Dimension of Threat. Open Access Research Journal of Biology and Pharmacy, 14 (1). 018-029. ISSN 2782-9979

In the wake of the COVID-19 pandemic, humanity faces a quieter but potentially more devastating crisis—antibiotic resistance. Once hailed as miracle drugs, antibiotics are rapidly losing their effectiveness as bacteria evolve faster than new treatments can be developed. The pandemic has exacerbated this global threat: overwhelmed healthcare systems, indiscriminate antibiotic use, and disrupted infection control practices have created ideal conditions for resistant strains to thrive. This review explores how antibiotic resistance has surged in the shadow of COVID-19, examining both clinical and environmental dimensions, particularly in vulnerable urban areas in the Global South. From misuse in medical settings to unchecked environmental contamination, the drivers of resistance are deeply rooted in modern living. With few new antibiotics on the horizon and rising barriers to development, the need for coordinated global action has never been more urgent. The article calls on policymakers, scientists, and communities to recognize this looming danger and act decisively, before resistant bacteria outpace our capacity to respond—turning once-treatable infections into untreatable killers.
