Symptoms and Signs of Non-Polio Enterovirus Infection

Doctor's Notes on Non-Polio Enterovirus Infection

Enteroviruses are common viruses spread among people by secretions from the gastrointestinal tract or sometimes by respiratory secretions. They are small RNA viruses that belong to the family Picornaviridae and are typically classified as polioviruses or non-polio enteroviruses. A number of different viral types belong to the non-polio enteroviruses, including Coxsackieviruses, echoviruses, enterovirus D68, and others.

Non-polio enterovirus infections often do not produce any symptoms or cause only mild illness with symptoms such as runny nose, cough, sneezing, fever, rash, mouth blisters, and body aches. Other non-polio enterovirus infections may cause meningitis, accompanied by symptoms such as painful headache, sensitivity to light, fever, stiff neck, irritability, and nausea and vomiting. Serious infections with non-polio enteroviruses are less common but may cause pericarditis (inflammation of the outer lining sac of the heart), myocarditis (inflammation of the heart muscle), encephalitis (inflammation of the brain), and paralysis.
