AURORA, Colo. -- The Centers for Disease Control and Prevention confirmed Monday that a rare respiratory virus has indeed sickened children in Colorado.

The disease, which is similar to a common cold but can develop into a serious illness, was discovered in three-quarters of the samples sent to the CDC for analysis.

Last week, Children's Hospital of Colorado said they had treated more than 900 since Aug. 18 for severe respiratory illness. Eighty-six were admitted to the hospital.

Doctors suspected the patients had human enterovirus 68 or EV-D68, but it was not confirmed at the time.

Children's said cases of severe respiratory illness are still on the upswing with 447 children seen in the emergency room and 39 admitted from Sept. 4 to Sept. 7.

Every major hospital in the metro area is seeing a surge in respiratory infections in kids, forcing hundreds into the ER and others into ICU. Rocky Mountain Hospital for Children reports a 5-7% spike in severe respiratory infections in kids.

Three year old Amaziah Chir Chir is one of those kids. He’s been in the Pediatric Intensive Care Unit since Tuesday. For nearly a week his dad has watched on as he breathes with the help of tubes and machines.

Job Kimeli, Amaziah’s dad said, “He’s doing much better today, but he’s still on high-flow oxygen.”

Amaziah has mild asthma, so when he came down with cold-like symptoms last week, his dad treated him at home and waited, but he got significantly worse and fast. Kimeli said, “He was breathing so fast you could see that he was using his abdominal muscles, going up and down so fast. You could tell he was really struggling. “

Dr. Tracy Butler at RMHC said, “Seeing your child on life support is very stressful, but they are seeing that they’re getting better.” But, she said she does expect to see more sick kids as this virus continues to spread, as its doing across the country.

“It happens to be, this virus, that causes in wheezing in kids, in particular, and it happens every couple years or so, and we’re getting the whole middle of the county his with this virus,” said Dr. Christine Nyquist. She’s the Medical Director for Infection Control at Children’s Hospital Colorado.  She says they’re seeing a 12-15% increase in children with severe respiratory problems. “One out of three children are coming to the ER with respiratory problems. That’s a lot.”

Amaziah’s dad says don’t wait to go to the ER if your child can’t breathe. “I think this viral infection progresses so fast that it doesn’t give you enough time to wait, so you have to do it fast.”

Children’s Hospital Colorado sent 25 samples to the CDC. ¾ of them tested positive for Enterovirus 68.

Ten states have contacted the CDC for assistance in investigating clusters of enterovirus — Colorado, North Carolina, Georgia, Ohio, Iowa, Illinois, Missouri, Kansas, Oklahoma, and Kentucky.

Enteroviruses, which bring on symptoms like a very intense cold, aren’t unusual. They’re actually common. When you have a bad summer cold, often what you have is an enterovirus, he said. The season often hits its peak in September.

The unusual situation now is that there have been so many hospitalizations.

The virus has sent more than 30 children a day to a Kansas City, Missouri, hospital, where about 15% of the youngsters were placed in intensive care, officials said.

In a sign of a possible regional outbreak, Colorado, Illinois and Ohio are reporting cases with similar symptoms and are awaiting testing results, according to officials in those states.

In Kansas City, about 475 children were recently treated at Children’s Mercy Hospital, and at least 60 of them received intensive hospitalization, spokesman Jake Jacobson said.

“It’s worse in terms of scope of critically ill children who require intensive care. I would call it unprecedented. I’ve practiced for 30 years in pediatrics, and I’ve never seen anything quite like this,” said Dr. Mary Anne Jackson, the hospital’s division director for infectious diseases.

“We’ve had to mobilize other providers, doctors, nurses. It’s big,” she said.

The Kansas City hospital treats 90% of that area’s ill children. Staff members noticed an initial spike on August 15, Jackson said.

“It could have taken off right after school started. Our students start back around August 17, and I think it blew up at that point,” Jackson said. “Our peak appears to be between the 21st and the 30th of August. We’ve seen some leveling of cases at this point.”

No vaccine for virus

This particular type of enterovirus — EV-D68 — is uncommon, but not new. It was first identified in the 1960s and there have been fewer than 100 reported cases since that time. But it’s possible, Pallansch said, that the relatively low number of reports might be because EV-D68 is hard to identify.

EV-D68 was seen last year in the United States and this year in various parts of the world. Over the years, clusters have been reported in Georgia, Pennsylvania, Arizona and various countries including the Philippines, Japan and the Netherlands.

An analysis by the CDC showed at least 30 of the Kansas City children tested positive for EV-D68, according to the Missouri Department of Health and Senior Services.

Vaccines for EV-D68 aren’t currently available, and there is no specific treatment for infections, the Missouri agency said.

“Many infections will be mild and self-limited, requiring only symptomatic treatment,” it said. “Some people with several respiratory illness caused by EV-D68 may need to be hospitalized and receive intensive supportive therapy.”

Some cases of the virus might contribute to death, but none of the Missouri cases resulted in death and no data are available for overall morbidity and mortality from the virus in the United States, the agency said.

Symptoms include coughing, difficulty breathing and rash. Sometimes they can be accompanied by fever or wheezing.

Jackson said physicians in other Midwest states reported cases with similar symptoms.

“The full scope is yet to be known, but it would appear it’s in the Midwest. In our community, meticulous hand-washing is not happening. It’s just the nature of kids,” Jackson said.

“Worst I’ve seen”

Denver also is seeing a spike in respiratory illnesses resembling the virus, and hospitals have sent specimens for testing to confirm whether it’s the same virus.

More than 900 children have gone to Children’s Hospital Colorado emergency and urgent care locations since August 18 for treatment of severe respiratory illnesses, including enterovirus and viral infections, hospital spokeswoman Melissa Vizcarra said. Of those, 86 have been sick enough to be admitted to the Aurora facility.

And Rocky Mountain Hospital for Children had five children in intensive care and 20 more in the pediatric unit.

“This is the worst I’ve seen in my time here at Rocky Mountain Hospital for Children,” Dr. Raju Meyeppan told the outlet. “We’re going to have a pretty busy winter at this institution and throughout the hospitals of Denver.”

Will Cornejo, 13, was among the children in intensive care at Rocky Mountain Hospital for Children after he came down with a cold last weekend and then woke up Tuesday night with an asthma attack that couldn’t be controlled with his medicine albuterol. His mother, Jennifer, called 911 when her son’s breathing became shallow, and her son was airlifted to the Denver hospital, she said.

Her son was put on a breathing tube for 24 hours.

“It was like nothing we’ve ever seen,” Jennifer Cornejo said. “He was unresponsive. He was laying on the couch. He couldn’t speak to me. He was turning white and his lips turned blue.

“We’re having a hard time believing that it really happened,” she added. “We’re much better now because he is breathing on his own. We’re on the mend.”

Restricting kids’ visits with patients

In East Columbus, Ohio, Nationwide Children’s Hospital saw a 20% increase in patients with respiratory illnesses last weekend, and Dr. Dennis Cunningham said patient samples are being tested to determine whether EV-D68 is behind the spike, WTTE reported.

Elsewhere, Hannibal Regional Hospital in Hannibal, Missouri, reported “recent outbreaks of enterovirus infections in Missouri and Illinois,” the facility said this week on its Facebook page.

Blessing Hospital in Quincy, Illinois, saw more than 70 children with respiratory issues last weekend, and seven of them were admitted, WGEM reported. The hospital’s Dr. Robert Merrick believes that the same virus that hit Kansas City is causing the rash of illnesses seen at the Quincy and Hannibal hospitals, which both imposed restrictions this week on children visiting patients, the affiliate said.

“Mostly we’re concerned about them bringing it in to a vulnerable patient. We don’t feel that the hospital is more dangerous to any other person at this time,” Merrick told WGEM.

Blessing Hospital is working with Illinois health officials to identify the virus, the hospital said in a statement.

While there are more than 100 types of enteroviruses causing up to 15 million U.S. infections annually, EV-D68 infections occur less commonly, the Missouri health agency said. Like other enteroviruses, the respiratory illness appears to spread through close contact with infected people, the agency said.

“Unlike the majority of enteroviruses that cause a clinical disease manifesting as a mild upper respiratory illness, febrile rash illness, or neurologic illness (such as aseptic meningitis and encephalitis), EV-D68 has been associated almost exclusively with respiratory disease,” the agency said.

Clusters of the virus have struck Asia, Europe and the United States from 2008 to 2010, and the infection caused relatively mild to severe illness, with some intensive care and mechanical ventilation, the health agency said.

To reduce the risk of infection, individuals should wash hands often with soap and water for 20 seconds, especially after changing diapers; avoid touching eyes, nose and mouth with unwashed hands; avoid kissing, hugging and sharing cups or eating utensils with people who are sick; disinfect frequently-touched surfaces such as toys and doorknobs; and stay home when feeling sick, the Missouri agency said.
