Can Enterovirus D68 Be Leading to Polio-Like Paralysis in Children?

During the last two months, a serious pediatric respiratory disease known as Enterovirus D68 (EV-D68) provides made its way directly into nearly every area of the U . s . States, sickening 500 kids in 42 states.


Herpes, which primarily affects newborns, children, and teens, leads to wheezing and difficulty breathing in. This week, the Facilities for Disease Control plus Prevention (CDC) announced that it is wanting to determine whether EV-D68 is also responsible for polio-like symptoms (limb weakness and paralysis) observed in some patients—polio will be also an enterovirus—and regardless of whether the virus is exactly what cause the deaths associated with four infected children.


Figuring out EV-D68 is proving in order to be a challenge. Many hospitals don't have checks that can distinguish in between it and hundreds associated with similar viruses—to associated with contact, they have to provide in the government or the particular CDC. To further confuse matters, CDC spokeswoman Darlene M. Foote says that will EV-D68 causes "no signs and symptoms at all" in several patients.

We caught upward with Mary Anne Knutson, a physician who minds the infectious disease section at Mercy Children's Medical center in Kansas City, Missouri—the first facility to review suspected cases of EV-D68—about her team's experience of the particular outbreak.

Mother Jones: Just how did your people recognize the first cases?

Martha Anne Jackson: On September 15, I got an email from our emergency physician, who was seeing a number of children—five or six over one shift—with severe respiratory system symptoms. Then we found out that we had an unusually high rate of positives on a test called Multiplex PCR with regard to a certain class of viruses: enteroviruses and rhinoviruses. The test does not say which one it is, and there are more than 100 rhinoviruses and one hundred enteroviruses. But rhinoviruses are more of a late fall/winter thing. We are right in the midst of our enterovirus season. We had unusually severe respiratory disease, a microbiology signal. From that, We were already worried this was an Enterovirus D68. I knew it has been rare, but in 2008, there were scattered reports in the literature of severe respiratory symptoms and EV-D68. But they had been in very tiny groupings of just a couple patients.

MJ: What did you perform when you began to suspect it was EV-D68?

MAJ: On August 19, we notified the CDC. By that period, beds were fully occupied and our own intensive care unit experienced several of these individuals. We asked other physicians nationwide and we obtained reports, especially from the particular Midwest, saying they had been seeing the same factor. By this point, we all have had more situations in our hospital compared to had been identified within the whole previous 10 years by the CDC. Now i'm guessing that the claims that are not impacted only need not recognized the particular cases yet. I believe this is likely to include virtually every state. Issue is D68, this is likely to be an unusually huge outbreak.

MJ: At exactly what point did you start to suspect that situations of limb weakness can also be caused simply by EV-D68?

MAJ: We understand that higher-numbered viruses within the D-class of enteroviruses can cause neurological symptoms. So we started looking in viral meningitis and seizures. We found a case of transverse myelitis, which is a very common neurologic syndrome. It entails pain or weakness in limbs, often in younger males. We found nothing out of the regular. But then we had an additional case a week later on. We looked at the MRI, and it looked more typical of what we'd see in a polio-like illness. In Denver colorado they were seeing nine cases [with neurological symptoms] over the course of about a 7 days. They had four instances that tested positive with regard to EV-D68. They had already asked for the CDC to come investigate. Then we had another case here.

MJ: But if only four of the cases tested positive for EV-D68, then why do they think that's what's causing the neurological symptoms?

MAJ: The virus is only going to be in the nose [the site of the test] for a period of time, and the timeframe between onset and presentation can be a few days to a few weeks. The virus could be gone by the time the limb weakness occurs. So far, there is still nothing to prove that the neurological symptoms have to do with EV-D68. But EV-D68 is the focus of the investigation.

MJ: Are the neurological signs and symptoms permanent or temporary?

MAJ: So much, most of these children with neurological symptoms are certainly not getting better. Take this particular with a grain associated with salt, because it's as well soon to say regardless of whether they will fully recuperate.

MJ: So what's following?

MAJ: The best question right now is: Is this likely to be like old-fashioned polio? How common is this particular going to be? Actually with polio, 95 % of patients had simply no symptoms, 4 percent experienced mild symptoms, 1 % had nonparalytic neurologic manifestation—1 in 1, 000 experienced a paralytic presentation. Indeed, you had countless children in iron lungs, but it was the vast minority.

MJ: What should parents know about the virus?

MAJ: We are reassuring parents that the most likely thing their kids have is a common cold. If your child has asthma, be aware of this respiratory manifestation, since we are seeing it more in children with a history of asthma. And even if your child doesn't have asthma, if they develop labored breathing, see a physician. Or if they develop limb weakness. This is not a subtle diagnosis.
