A standard case definition of a suspected case of Poliomyelitis was circulated among the medical profession in 1988 as a strategy for polio In addition, measles funds support approximately 80 international and national staff members (e.g., epidemiologists, surveillance officers, data managers, and laboratory coordinators) and fund diagnostic kits and laboratory equipment. with adequate stool specimens tested in 86% of all AFP cases (Table).
The four steps of surveillance are: finding and reporting children with acute flaccid paralysis (AFP) transporting stool samples for analysis response to outbreaks of other infectious diseases highlight the need for a more comprehensive global disease detection system.
In the Region of the Americas, the AFP surveillance system has been expanded or used as a model to fully implement case-based measles surveillance with laboratory confirmation of suspected cases. AFP Surveillance For the Polio Eradication program, crucial that AFP surveillance should not miss poliomyelitis cases Case definition has to catch as many cases as possible even those that are not polio: High sensitivity Low specificity All geographic areas to be covered, up to district All AFP cases investigated and polio excluded Alpha Fetoprotein (AFP): Alpha fetoprotein (AFP) is the most widely used biomarker for HCC surveillance, but this test has a sensitivity of only 47 to 64% and a specificity of 82 to 95% for detecting HCC among persons with HCV infection. 7.

The GPEI has developed and maintained AFP surveillance as the primary means of monitoring the impact of polio eradication activities, enabling prompt poliovirus detection and outbreak response throughout the world. Our study aims to determine the prevalence of non-poliovirus enteroviruses found in the surveillance of Acute Flaccid Paralysis (AFP) in Côte d'Ivoire and to study their distribution according to individual characteristics and associated factors.

UNICEF, World Health Organization, United Nations Population Fund. Acute flaccid paralysis (AFP) surveillance is key for global polio eradication. It is the process of detecting and investigating (including stool sample collection) of all AFP cases in children below 15 years of age. Laboratory surveillance for wild and vaccine-derived polioviruses. AFP surveillance is the intelligence network that underpins the entire eradication initiative. Acute Flaccid Paralysis or AFP is a clinical syndrome, which refers to a collection of signs and symptoms, instead of a diagnosis. Expansion of AFP surveillance systems has increased the responsibilities of SMOs in dozens of countries.
It is used to demonstrate the presence or absence of poliovirus and for certification of a country as polio-free [ 9, 10 ].
