A concerning surge in drug-resistant Shigella infections across the United States has prompted an alert from the Centers for Disease Control and Prevention (CDC), as reported by Power 105.3 on April 15, 2026. Shigellosis, an intestinal illness caused by the Shigella bacteria, is spreading in a form that is increasingly resistant to common antibiotics. According to a recent CDC report, cases of this highly drug-resistant strain have escalated dramatically, rising from virtually non-existent in 2011 to approximately 8.5% of all infections by 2023. The CDC's Morbidity and Mortality Weekly Report highlighted these findings, characterizing the trend as a major concern for both medical professionals and the public.
Shigellosis is known for its ease of transmission, typically spreading through direct contact with an infected person's stool, contaminated food, or surfaces. Symptoms commonly appear within one to two days of exposure and include severe diarrhea, which can be bloody, accompanied by fever and stomach pain. While most individuals recover within a week, some may experience prolonged illness or develop serious complications, such as life-threatening dehydration. The infection poses a particular risk to vulnerable populations, including young children, travelers, men who have sex with men, and individuals with compromised immune systems.
The rise of drug-resistant Shigella is particularly alarming because these infections do not respond to the most common antibiotics, and there are currently no FDA-approved oral medications available for treatment. The CDC has confirmed that approximately one-third of individuals infected with the resistant strain required hospitalization, and nearly half of those who reported their HIV status were also HIV positive. Crucially, over 80% of infected patients indicated they had not traveled internationally, underscoring that the superbug is spreading within the United States. The CDC emphasizes the critical need for ongoing monitoring, robust public health responses, and increased public education to curb the outbreak. Health officials are reiterating recommendations for meticulous handwashing with soap and water, avoiding raw or contaminated food, and staying home when ill to help prevent the spread of infection. Doctors have been advised by the CDC to report all cases of drug-resistant Shigella to local health departments and to adhere to new guidelines for managing these challenging infections, while the agency continues to research treatment options and promote hygiene awareness.
