"The COVID-19 pandemic pushed back years of progress made combating antimicrobial resistance (AMR) in the United States," leading to a surge in superbug infections, says a report released yesterday by the Centers for Disease Control and Prevention (CDC).
In a nutshell:Antimicrobial resistance (AMR) prevention lapsed, and antibiotics were overprescribed in hospitals overwhelmed by COVID-19, says the report. Hospital-onset infections and deaths increased about 15% between 2019 and 2020.
Specifically:
- Dangerous blood stream and urinary tract infections from Carbapenem-resistant Acinetobacter rose 78%.
- Hospital infections rose for deadly superbug yeast Candida auris (60%) and “nightmare bacteria,” Carbapenem-resistant Enterobacteriaceae (35%).
- 3 of 5 antimicrobial-resistant bacteria and fungi saw increased hospital infections.
Several factors led us here, says the CDC:
- Hospitals dealt with sicker patients using devices like ventilators and catheters that break the body’s protective barriers, enabling infection.
- Doctors leaned heavily on antibiotics—but since COVID-19 is viral, antibiotics had no effect. Over-prescription of antibiotics can fuel drug-resistant microbes.
- Data collection was delayed, leaving infections undetected and untreated.
- Progress in AMR prevention was undone at overburdened hospitals.
What should we do? We need improvements in AMR prevention and data —including from wastewater—judicious use of antibiotics, and development of new drugs, CDC says.
We also need to stabilize the antimicrobial ecosystem to support the research, development and commercialization of new and novel antimicrobials—by urgently enacting legislation like the bipartisan, bicameral PASTEUR Act, which would create critical ‘pull incentives’ for new drug development.
