Key Points
- Drug-resistant shigella caused 0% of US cases in 2011 but 8.5% by 2023.

Full Details
The Centers for Disease Control and Prevention (CDC) has issued a new warning about a drug-resistant strain of shigellosis, a bacterial infection causing severe diarrhea. According to the report, this resistant strain caused no infections nationwide in 2011, but by 2023, it was responsible for 8.5% of all shigellosis cases in the United States. The agency notes that this percentage is continuing to rise, indicating a growing public health concern. Shigellosis is typically spread through contaminated food, water, or surfaces, and the rise of drug-resistant variants complicates treatment options. This trend highlights the broader challenge of antimicrobial resistance in the US healthcare system.
Why It Matters
The rise of drug-resistant shigella could lead to longer illness durations, increased healthcare costs, and greater challenges in outbreak containment, underscoring the urgent need for antimicrobial stewardship.
