Enterovirus D68 (EV-D68) is one of more than 100 non-polio enteroviruses. This virus was first identified in California in 1962. EV-D68 can cause mild to severe respiratory illness and is likely spread from person to person when an infected person coughs, sneezes, or touches a surface that is then touched by others.
From mid-August to November 12, 2014, Centers for Disease Control and Prevention (CDC) or state public health laboratories have confirmed a total of 1,116 people in 47 states and the District of Columbia with respiratory illness caused by EV-D68.
Every year, enteroviruses and rhinoviruses cause millions of respiratory illnesses in children, this year, EV-D68 has been the most common type of enterovirus identified, leading to increases in illnesses among children and affecting those with asthma most severely. Other rhinoviruses and enteroviruses continue to be detected as well.
