CDC Warns Drug-Resistant Shigella Infections Are Rising in the U.S.

**Rise in Drug-Resistant Shigella Infections Raises Public Health Concerns**

The Centres for Disease Control and Prevention (CDC) has issued a warning regarding a significant rise in drug-resistant strains of Shigella, a bacterium responsible for the gastrointestinal illness shigellosis. Reported data indicates that cases of these resistant infections have surged by 8.5% across the United States from 2011 to 2023, highlighting an emerging public health threat.

Shigellosis is primarily transmitted through the fecal-oral route, which can occur through sexual contact or consumption of contaminated food and water. The symptoms associated with shigellosis are distressing and may include persistent diarrhoea, fever, and severe stomach pain. Persons infected typically exhibit symptoms within one to two days, with episodes generally lasting from five to seven days, although some individuals may experience prolonged illness.

The CDC’s analysis of over 16,700 Shigella samples from January 2011 to October 2023 revealed a concerning trend: no drug-resistant infections were identified during the period from 2011 to 2015, but by 2023, 8.5% of infections were confirmed to be resistant to standard antibiotic treatments. The first discovery of a drug-resistant strain was traced back to 2016, and it has predominantly affected adult males, with a median age of 41. Notably, 82.4% of those with reported travel histories had not recently travelled abroad, suggesting that the infection is spreading domestically.

Historically, Shigella infections were manageable with antibiotics; however, the emergence of strains resistant to essential medications such as ampicillin, azithromycin, ceftriaxone, ciprofloxacin, and trimethoprim-sulfamethoxazole has left healthcare providers with limited treatment options. Alarmingly, there is currently no FDA-approved oral treatment available for these infections, increasing the urgency for effective responses to this public health crisis.

Those most vulnerable to severe infection include children, travellers, individuals engaging in anal sex, and those experiencing homelessness. The CDC urges individuals with weakened immune systems to promptly seek medical advice if they experience symptoms indicative of shigellosis. Additionally, those with alarming symptoms such as high fever, bloody diarrhoea, frequent vomiting, or signs of dehydration should seek immediate medical attention.

To combat the spread of shigellosis, the CDC recommends several preventative measures. Regular handwashing is crucial to reduce the risk of infection, particularly after using the toilet or before preparing food. Individuals are also advised to avoid swallowing water while swimming and to adhere to safe practices regarding food and water consumption when travelling. Moreover, it is recommended that anyone infected refrain from sexual activity for a minimum of two weeks to prevent further transmission.

The rise in drug-resistant Shigella infections underscores the importance of public health efforts directed towards awareness and education about prevention strategies. As healthcare professionals grapple with these challenging cases, the CDC continues to monitor the situation closely in hopes of controlling the spread of this increasingly prevalent infection.
