COVID-19 and Antimicrobial Resistance: A Review

Area of Science:

• Infectious Diseases
• Public Health
• Microbiology

Background:

• The coronavirus pandemic (COVID-19) has overshadowed the escalating threat of antimicrobial resistance (AMR).
• Antimicrobial-resistant pathogens pose a significant risk in healthcare settings, complicating patient care.
• COVID-19 management is further challenged by the prevalence of AMR.

Purpose of the Study:

• To review early findings on the intersection of COVID-19 and AMR.
• To offer recommendations and lessons learned for enhancing antimicrobial stewardship.
• To emphasize the importance of judicious antibiotic use during the pandemic.

Main Methods:

• A rapid narrative review of published literature was conducted.
• Searches were performed on PubMed and Google Scholar using keywords related to COVID-19 and AMR.
• Included articles focused on early findings, clinical implications, and stewardship.

Main Results:

• Secondary bacterial infections are significant contributors to COVID-19 morbidity and mortality.
• Only a small proportion of COVID-19 patients require antibiotics for secondary bacterial infections.
• Antibiotic therapy or prophylaxis is generally not indicated for mild, suspected, or confirmed moderate COVID-19 unless clinically warranted.

Conclusions:

• The pandemic exposed vulnerabilities in global health systems and the limitations of current therapies against infections.
• Antimicrobial resistance represents a critical challenge, potentially leading to untreatable infections.
• Continuous research, development of new antimicrobials, and strengthened antimicrobial stewardship programs are essential to combat AMR.
