Summary
In the United States, infections caused by drug-resistant "nightmare bacteria" increased by 70% from 2019 to 2023, according to a CDC report. The rise involves bacteria with the NDM gene, which can resist even strong antibiotics called carbapenems. Misuse of antibiotics contributes to this increase, and many cases might be undetected, leading to further spread.
Key Facts
- Infections by drug-resistant bacteria grew 70% from 2019 to 2023 in the US.
- The CDC identified the NDM gene in bacteria as a significant factor in this rise.
- Carbapenems are usually effective antibiotics, but NDM-gene bacteria can resist them.
- About 4,341 cases of carbapenem-resistant infections were reported in 2023, with 1,831 involving the NDM gene.
- Antibiotic misuse contributes to antimicrobial resistance, allowing bacteria to adapt.
- The rate of NDM cases increased significantly from 0.25 to 1.35 per 100,000 people.
- The COVID-19 pandemic likely increased antibiotic use, contributing to resistance.
- Data might be underestimated as many states do not test for these infections, and key states like California and New York were not included in the study.
