Antimicrobial resistance (AMR) is an ongoing phenomenon. It is a significant public health issue that has existed long before the coronavirus disease of 2019 (COVID-19) pandemic. It develops as microorganisms undergo genetic mutations that allow them to survive despite antimicrobial treatment. This process is highly associated with excessive and often unnecessary antimicrobial pharmacotherapy, which was often discussed during the COVID-19 pandemic. This article explores how the pandemic has affected antimicrobial stewardship by shifting the focus away from antimicrobial resistance, as well as the impact of enhanced antibiotic usage and measures such as lockdowns, mandatory testing and vaccination on antimicrobial resistance. Although these measures were regarded as successful in terms of limiting the pandemic, they have significantly contributed to an already escalating AMR issue. Outpatient methods in primary care and intensive care units aiming to prevent severe COVID-19 disease have contributed to the spread of multidrug-resistant bacteria, while laboratories burdened with COVID-19 testing have indirectly interrupted the detection of these bacteria. In this review, we summarize the pathogens whose AMRe has been greatly affected by COVID-19 measures and emphasize the importance of efficient antimicrobial stewardship in future pandemic and non-pandemic states to promote the responsible use of antibiotics and minimize AMR.
