Increased incidence of Enterovirus causing Aseptic Meningitis this spring & summer

Laboratory confirmed enterovirus infections have been noted to be resulting in a higher than expected incidence of aseptic meningitis in young people within Alberta this spring and summer. The enterovirus serotyping which has been done on the positive lab specimens has shown the majority are Coxsackie A9.

To date 44/83 cases in Alberta are from the Edmonton Zone and most have been between 11-29 years old.

Most cases have presented with headache, stiff neck and fever. Some have also experienced rash, photophobia and GI symptoms. Some of the cases have been hospitalized for a few days, but to date the affected individuals have recovered completely with supportive treatment.

Enterovirus is spread through direct contact with nose and throat secretions as well as the feces of infected persons, or by droplet spread. Asymptomatic individuals can transmit infection. Diagnosed and probable cases should stay home until the symptoms resolve, unless hospital admission for supportive or other therapy is indicated. Promoting hand washing, cough etiquette, discouraging sharing of water bottles, and other hygienic measures at home and in the community will help prevent transmission to others.
