Antibiotic-resistant Shigella is a growing concern in the United States, as cases of bacterial infection continue to rise.
The U.S. Centers for Disease Control and Prevention (CDC) has warned of increasing cases of antibiotic-resistant strains of these bacteria, called XDR Shigella, which are resistant to all commonly recommended antibiotics.
The agency reported that the proportion of approximately 450,000 annual Shigella infections in the United States resistant to all known antibiotic treatments has risen from none in 2015, 0.4 percent in 2019, and 5 percent in 2022, indicating potentially greater spread.
