Abstract

Classical Swine Fever is a contagious viral disease affecting pigs and wild boars. Is considered the most economical important disease in swine production around the world. Ecuador is a country where the disease is endemic, but since 2014 a control program has been implemented, applying strategies for surveillance, control and projecting the future eradication. The veterinary epidemiological surveillance system represents the backbone of a complex process, applied for animal health and productivity improvement. This process includes activities such as farm inspection, gathering and processing data, sampling, health and geographic data analysis, risk factors interpretation and serologic or molecular diagnosis. Those prevention and control activities have strong impact in the productive chain and in the lives of thousands of producers. The evaluation of the epidemiologic surveillance system is an essential process to go forward in to the control and eradication plans, because the more sensitive, trustworthy and representative the system is, the better the comprehension of the disease dynamics will be. Therefore, the efficiency and effectiveness of the proposed activities are likely to be able to decrease and eradicate the disease in less time. One of the best strategies applied to the epidemiologic surveillance improvement is the risk-based surveillance because is created in accordance with the specific real needs based on the evaluation. This technique will allow an effective system restructuring. Namely, design modifications capable of maximizing its sensitivity, considering the present risk factors in the target population. The objective of this work is to evaluate the classical Swine Fever surveillance system applied in Ecuador, and propose a risk-based surveillance model supporting the eradication process in that country.
