Epidemiological surveillance of acute flaccid paralysis in the territory of the Republic of Armenia for 2003-2015

摘要

Purpose: Starting from 1988 and up to 2014, cases of wild poliovirus have decreased by over 99% as a result of an effective expanded immunization program and epidemiological surveillance of acute flaccid paralysis (AFP). There are only two countries that remain polio-endemic (Afghanistan and Pakistan). The Republic of Armenia was certified by the WHO as a polio-free zone in 2002. The purpose of the study is the implementation of an active epidemiological surveillance of AFP detectability among the population of Armenia by investigation of stool samples of patients obtained from AFP cases and their contacts, also from children of high-risk group (boarding schools).
