Cases of extensively drug-resistant Shigella infections are rising in the United States, prompting the Centers for Disease Control and Prevention (CDC) to warn of a growing public health threat. The agency says the proportion of drug-resistant cases has climbed sharply in recent years, with limited treatment options now available for some infections.
In a new report released on April 9, the CDC highlighted that resistance has increased from 0% of tested isolates between 2011 and 2015 to 8.5% in 2023, signalling a significant shift in how the infection is spreading and responding to treatment.
