Drug-resistant strain of Shigella bacteria prompts warning from CDC
The Centers for Disease Control and Prevention issued a health advisory on Friday about an increase in an antibiotic-resistant strain of the Shigella bacteria.
abcnews.comHere’s the latest guidance on Shigella infections based on recent public health updates.
- What it is: Shigella is a bacterial cause of dysentery with symptoms like diarrhea (often bloody), fever, and stomach cramps. It spreads via fecal-oral routes, contaminated food/water, surfaces, or close contact.
- Why it’s notable now: Public health agencies have recently highlighted rising concerns about antibiotic-resistant Shigella strains, which can limit treatment options and complicate outbreak control. In several recent reports, health authorities warned about drug-resistant Shigella (including strains resistant to multiple first-line antibiotics) and urged clinicians to test susceptibility and report cases promptly. This trend has driven calls for heightened prevention, rapid diagnosis, and careful antibiotic stewardship. These warnings reflect ongoing surveillance and are part of broader antimicrobial resistance concerns.[2][3][4][6]
- Symptoms and who’s at risk: Most infections are self-limiting in healthy people, but severe disease can require treatment, especially in young children, older adults, and those with weakened immune systems. Transmission can occur via sexual contact, childcare environments, travel, and handling contaminated food or water.[3]
- Public health actions you can take locally (Los Angeles/CA):
- Practice strict hand hygiene, especially after restroom use and before preparing or handling food.
- Safely wash and disinfect surfaces and kitchen equipment; avoid preparing food for others when ill.
- If you have diarrhea persisting >1–2 days or high fever, seek medical care and inform your clinician about recent travel or potential exposure.
- Clinicians should obtain stool testing, consider repeated testing if symptoms persist, and perform antibiotic susceptibility testing before prescribing antibiotics when possible.
- Report suspected or confirmed cases to local public health authorities as required.
Illustrative example: An outbreak row in a city can involve dozens of linked cases with a mix of travel-related and community transmission; health departments coordinate case finding, lab confirmation, and guidance on hygiene measures to curb spread.[4][2]
