The Massachusetts Department of Public Health (MDPH) has released an MDPH Entero D68 Fact Sheet. Enteroviruses cause respiratory and gastrointestinal illness, rash, and neurologic illnesses, such as aseptic meningitis and encephalitis. While most infections cause mild or no symptoms, some can be severe. The current outbreak of enterovirus D68 has been predominantly associated with respiratory disease and not nervous system infection. Patients with asthma have been experiencing more severe symptoms, like they would with any respiratory infection, and should seek care early.
