Shigella infection and antibiotic resistance in US

Overview

Health experts are reporting a rise in Shigella infections in the United States, accompanied by growing concerns over antibiotic resistance. While the bacteria typically spreads through contaminated food, water, or poor hygiene, recent data indicates a shift in transmission patterns. Specifically, sexual transmission has grown significantly faster than traditional routes, leading to increased cases among gay and bisexual men.

A critical development is the emergence of extensively drug-resistant (XDR) strains. CDC data shows that resistance to five common antibiotics rose from 0% in 2011 to 8.5% by 2023. Clinical reports, including observations from UCLA, highlight this shift, noting that medical staff are seeing monthly occurrences of XDR Shigella compared to much lower historical frequencies. This evolution from a treatable intestinal pathogen to a potential ‘superbug’ complicates management for clinics and public health departments.

Recent monitoring by the Louisiana Department of Health and the CDC indicates that the infection is becoming increasingly difficult to treat due to resistance to current medical protocols. The CDC estimates there are currently over 200,000 cases nationwide, with approximately half involving drug-resistant strains. While case rates in Louisiana currently remain below the national average, the state has already confirmed more cases in 2026 than were reported throughout the entirety of 2025.

Symptoms of the infection include diarrhea, fever, and abdominal cramps. In severe cases, the infection can lead to dehydration, septic shock, or neurological complications.
