CDC Reports Alarming Increase in Polio-Mimicking Virus Among US Kids

The Centers for Disease Control and Prevention (CDC) reported a concerning rise in a polio-like virus affecting children across the United States. This respiratory virus, known as enterovirus D68 (EV-D68), gained attention due to its potential to cause a rare but serious condition called acute flaccid myelitis (AFM). AFM affects the nervous system and leads to severe weakness in the arms and legs, primarily in young children.

Rising Concerns

Health officials across the United States grew increasingly worried about the spread of a respiratory virus linked to paralysis in children. The virus, identified as enterovirus D68 (EV-D68), showed a significant increase in wastewater samples nationwide. This surge raised concerns about a potential rise in cases of acute flaccid myelitis (AFM), a rare but serious condition affecting the nervous system.

Researchers detected a notable increase in EV-D68 levels through wastewater monitoring across the country. Alexandria Boehm, program director of WastewaterSCAN and professor at Stanford University, confirmed the rising presence of EV-D68 nucleic acids in wastewater samples. This detection method provided valuable early warning signs of potential outbreaks.

Seasonal Patterns

Epidemiologists noted that the timing of the EV-D68 increase coincided with historical patterns of AFM outbreaks. September traditionally marked the peak month for AFM cases, according to past data. This alignment of seasonal trends with the current virus detection raised additional concerns among health experts.

Understanding Enteroviruses

Enteroviruses, including EV-D68, were identified as a common group of viruses affecting many people. Most enterovirus infections result in mild symptoms such as runny nose, cough, and headache. However, the D68 strain gained notoriety for its potential to cause more serious health issues. The contrast between typical mild symptoms and the rare but severe complications of EV-D68 highlighted the complex nature of these viruses.

Historical Context

The year 2014 marked a significant shift in the understanding of EV-D68 and its connection to AFM. That year, the United States experienced its first notable spike in pediatric AFM cases, with 120 children diagnosed. This outbreak brought attention to the potential severity of EV-D68 infections. The 2014 cases served as a wake-up call for health officials and researchers to investigate the link between the virus and AFM.

Impact on Affected Children

Children diagnosed with AFM faced significant challenges in their recovery process. There was no specific cure or treatment for the paralysis caused by the condition. Many affected children required years of intensive physical therapy to regain function. Despite these efforts, some children were left with lasting disabilities that altered their daily lives.

Ongoing Research

Researchers continued to investigate the complex behavior of EV-D68 and its connection to AFM. Experts considered various factors that might influence the virus’s impact, including potential changes in the virus itself or shifts in population immunity. Dr. Kevin Messacar, a pediatric infectious disease physician, emphasized the ongoing nature of this research.

Current Case Numbers

The Centers for Disease Control and Prevention (CDC) reported 13 confirmed AFM cases in 2024 at the time of the report. Since 2014, a total of 758 AFM cases were documented across the United States. These numbers represented a significant increase from the rare occurrences of AFM before 2014.

Personal Impact

The Kagolanu family from Los Altos, California, shared their experience with AFM. Their son, Vishnu, was diagnosed with the condition in 2014 at the age of seven. The family recounted the sudden onset of symptoms during a game night, which rapidly progressed to full paralysis.

Challenges in Diagnosis and Treatment

Vishnu’s case highlighted the challenges faced by medical professionals in diagnosing and treating AFM. Doctors initially struggled to identify the cause of his symptoms, as the connection between EV-D68 and AFM was not yet established. The lack of understanding and available treatments left families like the Kagolanus feeling helpless and frustrated.

Recovery and Resilience

Despite the initial grim prognosis, Vishnu made significant progress in his recovery through years of physical therapy. He regained his ability to walk, though some limitations remained. Vishnu’s journey inspired him to create a nonprofit organization called Neurostronger, aimed at supporting children with neurological conditions.

Developing Treatments and Raising Awareness

Researchers, including Dr. Buddy Creech from Vanderbilt University Medical Center, worked on potential treatments for EV-D68 and AFM. Early studies of a monoclonal antibody showed promise in preventing AFM in mouse models. While these efforts provided hope for future interventions, the development process was expected to take several years. In the meantime, increased awareness and support for affected individuals remained crucial in addressing the challenges posed by EV-D68 and AFM.
