Enterovirus D68 (EV-D68) is one of more than 100 non-polio enteroviruses. This virus was first identified in California in 1962.
What are the symptoms of EV-D68 infection?
EV-D68 can cause mild to severe respiratory illness.
- Mild symptoms may include fever, runny nose, sneezing, cough, and body and muscle aches.
- Severe symptoms may include wheezing and difficulty breathing. See EV-D68 in the U.S., 2014 for details about infections occurring this year.
Anyone with respiratory illness should contact their doctor if they are having difficulty breathing or if their symptoms are getting worse.
How does the virus spread?
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 a surface that is then touched by others.
What time of the year are people most likely to get infected?
In the United States, people are more likely to get infected with enteroviruses in the summer and fall. Cases are likely to decline later in the fall.
How common is EV-D68 in the United States?
In general, a mix of enteroviruses circulates every year, and different types of enteroviruses can be common in different years. Small numbers of EV-D68 have been reported regularly to CDC since 1987. However, this year the number of people reported with confirmed EV-D68 infection is much greater than that reported in previous years. See EV-D68 in the U.S., 2014 for details about infections occurring this year.
