Introduction:
The COVID-19 pandemic has intensified global health challenges, including a silent but escalating crisis: multidrug-resistant organisms (MDROs). As healthcare systems strained under viral outbreaks, infection control and antimicrobial stewardship efforts suffered, accelerating the spread of antimicrobial resistance (AMR).
Areas Covered:
This review examines the indirect effects of the COVID-19 pandemic on AMR, emphasizing changes in antibiotic utilization, healthcare-associated infections, and resistance trends. Global and regional epidemiological data are presented, with a special focus on Taiwan's evolving MDROs landscape, clinical burden, and strategic responses.
Expert Opinion:
COVID-19 has both exposed and intensified vulnerabilities in AMR control. While the pandemic fostered certain infection control practices, it also disrupted antimicrobial oversight, leading to surges in MDROs prevalence. Taiwan's experience underscores the value of coordinated guidelines, real-time diagnostics, and artificial intelligence-driven stewardship. Rebuilding and future-proofing AMR responses requires integrated global policies, sustained surveillance, and innovation in diagnostics and therapeutics. Unless comprehensive action is taken, MDROs may emerge as the defining post-pandemic threat to modern medicine.
Insights
The COVID-19 pandemic worsened antimicrobial resistance (AMR) by disrupting infection control and increasing multidrug-resistant organisms (MDROs). Strategic responses, like those in Taiwan, are crucial to combat this escalating global health threat.
Area of Science:
- Global Health
- Infectious Diseases
- Microbiology
Background:
- The COVID-19 pandemic created significant global health challenges.
- Healthcare systems faced immense strain, impacting infection control and antimicrobial stewardship.
- This led to an accelerated spread of antimicrobial resistance (AMR) and multidrug-resistant organisms (MDROs).
Purpose of the Study:
- To review the indirect effects of the COVID-19 pandemic on AMR.
- To analyze changes in antibiotic utilization, healthcare-associated infections, and resistance trends.
- To present epidemiological data, focusing on Taiwan's MDRO landscape and responses.
Main Methods:
- Review of global and regional epidemiological data on AMR and MDROs.
- Analysis of antibiotic utilization patterns during the pandemic.
- Case study examination of Taiwan's strategies and outcomes.
Main Results:
- The pandemic exposed and intensified vulnerabilities in AMR control.
- Disrupted antimicrobial oversight led to increased MDRO prevalence.
- Taiwan's experience highlights the effectiveness of coordinated guidelines and AI-driven stewardship.
Conclusions:
- Multidrug-resistant organisms (MDROs) pose a significant post-pandemic threat.
- Integrated global policies, sustained surveillance, and innovation are essential for future AMR responses.
- Taiwan's strategic approach offers valuable lessons for combating AMR.
