Rising Cases of Paralytic Illness Caused by Enterovirus D68

Chapter 1: Understanding Enterovirus D68
A troubling trend is surfacing across the United States — the resurgence of a respiratory virus capable of causing a severe paralytic illness in children. Recent wastewater surveillance has indicated a marked increase in the detection of Enterovirus D68 (EV-D68), which has raised concerns about a potential rise in cases of acute flaccid myelitis (AFM), a rare yet devastating neurological disorder.
The Enterovirus Phenomenon
Enteroviruses are commonly encountered, with most people experiencing only mild symptoms like runny noses and headaches. However, the EV-D68 strain poses a more serious threat, first drawing significant attention in 2014 when the U.S. faced a notable increase in pediatric AFM cases. This virus has shown a disturbing pattern of resurgence, typically following a biennial cycle of increased AFM occurrences.
The Cyclical Pattern of AFM
Since 2014, the U.S. has experienced notable AFM outbreaks, with spikes occurring in 2016 and 2018. The pandemic-related lockdowns in 2020 led to a decrease in viral transmission, which curiously correlated with a lack of expected AFM cases in 2022 despite the presence of EV-D68 in wastewater samples. This discrepancy has left experts searching for answers.
The Unexplained Disconnect
Researchers are perplexed by the apparent disconnect between the resurgence of EV-D68 and the absence of a corresponding increase in AFM cases. Dr. Kevin Messacar, an infectious disease specialist at Children’s Hospital Colorado, notes that while the virus linked to previous AFM cases has been identified, the anticipated paralysis cases have not followed suit.
Theories and Speculations
Experts are examining several hypotheses to unravel this mystery. It is possible that the virus has mutated, or perhaps increased immunity among the U.S. population is preventing severe manifestations of the illness. However, the exact reasons for this puzzling phenomenon are still under investigation.
The Ongoing Impact of AFM
Despite a decrease in reported AFM cases, the enduring impact on affected families cannot be overlooked. Since 2014, there have been 758 documented cases, leaving many families grappling with the long-term consequences of paralysis. The story of the Kagolanu family and their son, Vishnu, who was among the first diagnosed with AFM, exemplifies the profound challenges faced by these families.
Vishnu's Journey: A Heartbreaking Tale
In November 2014, while playing Monopoly, 7-year-old Vishnu began tilting his head uncontrollably, ultimately losing movement in his arms and legs within an hour. At the time, the link between EV-D68 and AFM was not yet established, leaving his family and doctors in confusion.
The Road to Recovery
Doctors warned Vishnu's family that he might never regain mobility, a devastating prospect for a boy who was once the "king of the playground." Over the years, Vishnu underwent extensive physical therapy, striving to walk again, though he still bears the physical reminders of his battle with this mysterious illness.
Empowering Others Through Neurostronger
Despite the obstacles associated with AFM, Vishnu has chosen to inspire others. He founded a nonprofit organization called Neurostronger, dedicated to fundraising and raising awareness for children facing neurological challenges. His story is a powerful testament to the resilience of those affected by this debilitating condition.
The Quest for Effective Treatments
As the medical community contemplates the resurgence of EV-D68 and the potential for another wave of AFM cases, the pressing need for effective treatments becomes increasingly clear. Dr. Buddy Creech, a pediatric infectious disease specialist at Vanderbilt University Medical Center, and his team are conducting safety studies on a monoclonal antibody that could potentially halt EV-D68's progression.
The Frustration of Limited Treatment Options
"We all get frustrated when we reach this point and lack effective antiviral medications," Dr. Creech expresses. "There’s very little we can offer these children." This shortage of treatment options adds to the hurdles faced by families and healthcare providers.
A Call for Vigilance and Awareness
As the country prepares for the possibility of another spike in AFM cases, the need for increased awareness and vigilance is paramount. Epidemiologists like Caitlin Rivers from the Johns Hopkins Center for Health Security stress the importance of monitoring the situation closely, especially during the time of year when AFM cases typically peak.
Confronting the Viral Challenge with Innovation
The resurgence of EV-D68 and the looming threat of acute flaccid myelitis highlight the continuous battle against emerging viral threats. While the medical community works to understand this complex condition, stories of resilience, such as that of Vishnu Kagolanu, inspire hope. As researchers strive to find effective treatments and deepen our understanding of the virus, collective efforts from healthcare professionals, researchers, and the community will be vital in addressing this growing challenge and safeguarding the health of children across the U.S.
