In the cases, limb weakness first appeared an average of just five days after the start of a mild viral illness.

And enteroviruses—like some other viral respiratory infections—often peak when AFM does, in late summer to fall. Collectively, the circumstantial evidence points to the idea that in some children, respiratory infections from enteroviruses spill over into motor neurons in the spinal cord and cause devastating damage.
But while that hypothesis seems like a slam-dunk, the evidence to back up the connection between EV-D68 and AFM has been maddeningly hard to get. From the confirmed AFM cases in , health officials were able to collect just respiratory samples.
Of those, only 30 tested positive for EV-D68, while ten others were positive for EV-A71 and 14 were positive for other enterovirus infections. Likewise, officials collected 74 samples of cerebrospinal fluid from the cases, and only one tested positive for EV-D One other sample tested positive for EV-A The main purpose of the call to action is to prompt doctors to speed up their reporting, Dr.

Tom Clark tells Ars. Faster reporting could help officials collect more samples faster, as well as try out additional tests. Beyond fingering a specific virus behind AFM cases, there are still plenty of other questions to answer.
Namely, why are cases suddenly popping up now, or in these two-year cycles, or in certain, otherwise healthy children, and how is AFM best treated? Investigators have found evidence of EV-D68 infections in sets of siblings, while only one sibling develops AFM, hinting at some unknown, individual-specific risk factors.
Answers to these questions are far more speculative. Upticks in GBS cases were noted in the wake of recent Zika outbreaks , for instance. Unlike AFM, GBS tends to start with weakness in the legs and back and progress toward paralysis relatively slowly, over weeks rather than days. Intriguingly, a report from suggested that a single virus— West Nile virus —was associated with both AFM cases and a GBS-like syndrome in a cluster of 32 patients in Colorado. West Nile virus infects birds in the US and spreads to humans via mosquito bites, typically causing asymptomatic infections or ones with vague viral symptoms, such as fever and body aches.
Another odd ripple comes from a report from an international team of researchers who noted that a cluster of eight cases of AFM during an outbreak of hand-foot-and-mouth disease caused by EV-A71 in Malaysia also seemed to be associated with a second virus, an unusual adenovirus.
This led them to wonder if the overlap or interactions of the viruses had something to do with the severe illness.
