Echoviruses diagnosed in two Children presenting with Acute Flaccid Paralysis (AFP): An Illustration of the Evolving role of the Zambian AFP Surveillance Programme in the Absence of Polio

ABSTRACT

Background: The Enteric Cytopathic Human Orphan virus commonly referred to by the acronym ECHO virus has been known to cause acute flaccid paralysis (AFP). Zambia has since 1993 run a national AFP surveillance program to primarily detect and confirm poliomyelitis cases. Through this program other enteroviruses have been confirmed to be associated to the non-polio cases. We describe two patients with acute flaccid paralysis presenting like poliomyelitis and yet are non-polio cases associated with ECHO virus.
