Enterovirus D68 Hits Michigan


KENT COUNTY, MI – The CDC confirms three cases of EV-D68 (enterovirus) in EV68-infographicMichigan. One of these cases is confirmed in Kent County.

Enterovirus D68 is a rare, highly contagious strain of the respiratory illness.  According to the CDC, symptoms include fever, runny nose, sneezing, coughing and body and muscle aches.




Enterovirus D68 (EV-D68) is one of many non-polio enteroviruses. This virus was first identified in California in 1962, but it has not been commonly reported in the United States.

EV-D68 can cause mild to severe respiratory illness.

  • Mild symptoms may include fever, runny nose, sneezing, cough, and body and muscle aches.
  • Most of the children who got very ill with EV-D68 infection in Missouri and Illinois had difficulty breathing, and some had wheezing. Many of these children had asthma or a history of wheezing.

Since EV-D68 causes respiratory illness, the virus can be found in an infected person’s respiratory secretions, such as saliva, nasal mucus, or sputum. EV-D68 likely spreads from person to person when an infected person coughs, sneezes, or touches contaminated surfaces.

From mid-August to September 19, 2014, a total of 160 people in 22 states were confirmed to have respiratory illness caused by EV-D68. (See States with Lab-confirmed Enterovirus D68.) The cases of EV-D68 infection were confirmed by the CDC or state public health laboratories that notified CDC.

EV-D68 infections are thought to occur less commonly than infections with other enteroviruses. However, CDC does not know how many infections and deaths from EV-D68 occur each year in the United States. Healthcare professionals are not required to report this information to health departments. Also, CDC does not have a surveillance system that specifically collects information on EV-D68 infections. Any data that CDC receives about EV-D68 infections or outbreaks are voluntarily provided by labs to CDC’s National Enterovirus Surveillance System (NESS). This system collects limited data, focusing on circulating types of enteroviruses and parechoviruses.

In general, the spread of enteroviruses is often quite unpredictable, and different types of enteroviruses can be common in different years with no particular pattern. In the United States, people are more likely to get infected with enteroviruses in the summer and fall.

In general, infants, children, and teenagers are most likely to get infected with enteroviruses and become ill. That’s because they do not yet have immunity (protection) from previous exposures to these viruses. We believe this is also true for EV-D68.

Among the EV-D68 cases in Missouri and Illinois, children with asthma seemed to have a higher risk for severe respiratory illness.

EV-D68 can only be diagnosed by doing specific lab tests on specimens from a person’s nose and throat.

Many hospitals and some doctor’s offices can test ill patients to see if they have enterovirus infection. However, most cannot do specific testing to determine the type of enterovirus, like EV-D68. Some state health departments and CDC can do this sort of testing.

CDC recommends that clinicians only consider EV-D68 testing for patients with severe respiratory illness and when the cause is unclear.

Respiratory illnesses can be caused by many different viruses and have similar symptoms. Not all respiratory illnesses occurring now are due to EV-D68. Anyone with respiratory illness should contact their doctor if they are having difficulty breathing, or if their symptoms are getting worse.

There is no specific treatment for people with respiratory illness caused by EV-D68.

For mild respiratory illness, you can help relieve symptoms by taking over-the-counter medications for pain and fever. Aspirin should not be given to children.

Some people with severe respiratory illness may need to be hospitalized .

There are no antiviral medications currently available for people who become infected with EV-D68.

You can help protect yourself from respiratory illnesses by following these steps:

  • 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, especially if someone is sick.

Also, see a graphic that shows these prevention steps.

Since people with asthma are higher risk for respiratory illnesses, they should regularly take medicines and maintain control of their illness during this time. They should also take advantage of influenza vaccine since people with asthma have a difficult time with respiratory illnesses.

CDC recommends:

  • discuss and update your asthma action plan with your primary care provider.
  • take your prescribed asthma medications as directed, especially long term control medication(s).
  • be sure to keep your reliever medication with you.
  • if you develop new or worsening asthma symptoms, follow the steps of your asthma action plan. If your symptoms do not go away, call your doctor right away.
  • parents should make sure the child’s caregiver and/or teacher is aware of his/her condition, and that they know how to help if the child experiences any symptoms related to asthma.
