Enterovirus D68 (EV-D68) is one of more than 100 non-polio enteroviruses. EV-D68 virus was first identified in the USA in 1962. Enteroviruses are a common cause of human disease and can cause mild to severe respiratory illness. A mix of enteroviruses circulates in different areas of the world every year. These viruses are a frequent cause of summer and autumn colds.
EV-D68 spreads when an infected person coughs, sneezes, or touches a surface that is then touched by others. It may also spread through contact with an infected person's faeces (poo).
