Recent Wastewater Analysis

Recent wastewater analysis has revealed a concerning rise in the presence of enterovirus D68 (EV-D68) in New Hampshire, with five out of six samples taken from Dover testing positive over the last 10 days. This respiratory illness has been linked to polio-like symptoms and poses a serious risk, particularly to children.

Nationwide Trends

According to data provided by the nonprofit organization WastewaterSCAN, EV-D68 is showing medium levels in 323 out of 429 samples tested nationwide. This surge is observed not just in New Hampshire, but across several states in the South and Northeast, raising alarms among health officials.

Implications of EV-D68

The implications of EV-D68 extend beyond mild symptoms like a runny nose or cough. It can lead to acute flaccid myelitis (AFM), a neurological condition that results in sudden muscle weakness, potentially leaving some affected children unable to move their limbs or even facial muscles. While there have only been 13 confirmed cases of AFM this year, several more are currently under investigation.

Confirmed AFM Cases

States reporting confirmed AFM cases include California, Florida, New York, and Texas, among others. This mysterious condition has been the subject of intense research since AFM cases began increasing in 2014, with 758 confirmed cases documented since tracking began. Despite the absence of a direct link to the enterovirus that causes polio, the similarities in severity raise significant concerns.

Past Patterns and Predictions

Past patterns suggest that AFM cases typically trend upward in September, correlating with the increased circulation of enteroviruses during this season. However, health experts, including infectious disease specialist Dr. Kevin Messacar, acknowledge the unpredictability of these trends, noting that expectations for a rise in AFM cases following spikes in D68 infections in previous years have not materialized, possibly due to changes in viral behavior or increased herd immunity.

Transmission and Prevention

D68 spreads easily through respiratory secretions, direct contact with infected individuals, or contaminated surfaces. The absence of a vaccine adds an additional layer of caution, making preventative measures critical. The CDC recommends thorough handwashing, regular disinfection of commonly touched surfaces, and practicing proper respiratory etiquette to minimize transmission risk.

Symptoms to Monitor

Parents and caregivers should remain vigilant for both respiratory symptoms and potential signs of AFM, which include muscle weakness and facial paralysis. Key symptoms to monitor include:

Enterovirus D68 Symptoms

- Stuffy or runny nose - Cough - Fever - Muscle pain or body aches - Sore throat - Wheezing - Shortness of breath - Diarrhea

AFM Symptoms

- Weakness - Slurred speech - Difficulty swallowing - Drooping eyelids - Difficulty moving eyes - Facial paralysis - Pain in back, neck, arms, or legs

Conclusion

As health officials continue to investigate this troubling trend, communities are urged to stay informed and adhere to recommended preventative practices. The upcoming months could prove critical in battling this stealthy virus and preventing further outbreaks of AFM. Stay safe and informed!
