Motion-based video monitoring for early detection of livestock diseases: The case of African swine fever
PLOS ONE published this new research article
Body temperature and motion: Evaluation of an online monitoring system in pigs challenged with Porcine Reproductive & Respiratory Syndrome Virus
New research article published in Research in Veterinary Science journal.
Highly contagious and emerging diseases cause significant losses in the pig producing industry worldwide. Rapid and exact acquisition of real-time data, like body temperature and animal movement from the production facilities would enable early disease detection and facilitate adequate response. In this study, carried out within the European Union research project RAPIDIA FIELD, we tested an online monitoring system on pigs experimentally infected with the East European subtype 3 Porcine Reproductive & Respiratory Syndrome Virus (PRRSV) strain Lena. We linked data from different body temperature measurement methods and the real-time movement of the pigs.

|Dr. Sanchez-Vizcaino is the director of the OIE reference laboratory for African Swine Fever and a full professor of animal health at the Veterinary School of the Universidad Complutense of Madrid, Spain. The scientific contributions of Professor Sanchez-Vizcaino have notably contributed to the control and eradication of various animal diseases, among them the African Swine Disease, Horse Sickness and Classical Swine Disease. All of that thanks to the development of new methods and fast and sensitive diagnostic reagents, new epidemiologic strategies as well as the development of new vaccines.
His current scientific interest is centered in the study of animal infectious diseases and particularly in the development of new diagnostic techniques and new strategies for its control by means of analyzing the risk and development of epidemiologic models as well as establishing networks for sanitary monitoring.
This week we have the pleasure of hosting the researchers Dr. Manabu Yamada and Dr. Kentaro Masujin, both from the National Insitute of Animal Health (NIAH) in Japan.
Dr. Manabu Yamada is Principal Researcher at the Exotic Disease Research Unit of the Division of Transboundary Animal Disease (TAD) and has more than 17 years experience studying the viral disease in domestic animals.
Dr. Kentaro Masujin is Senior researcher at Exotic Disease Research Station and his work focuses in the characterization of African Swine Fever virus.
The visit will focus in the exchange of knowledge concerning African Swine fever virus diagnosis.
Next tuesday July 11, 2017 at the Mathematics Faculty of the UCM, Eduardo Fernánez Carrión will defend his doctoral thesis titled "Mathematical models for introduction, spread and early detection of infectious diseases in veterinary epidemiology" directed by Ángel Manuel Ramos, Benjamín Ivorra and Beatriz Martínez López.
Epidemiology is a discipline that studies the distribution and the factors related to the spread of (infectious) diseases in susceptible populations, and then uses this knowledge to control them. In this discipline, mathematical modeling plays a fundamental role in explaining the influence of potential risk factors, patterns of disease spread and the effects produced.
Applying mathematical models to epidemiology requires identifying the variables that influence the behavior of a disease in order to obtain a set of equations whose solution agrees with what happens in reality. The goal is to generate epidemiological models that not only explain the spread of diseases based on past experimental information, but also predict possible future scenarios. In this way, mathematical modeling is often the basis for decisions and practices aimed at preventing, controlling or eradicating disease.
The present thesis has focused on the development of three tools that cover surveillance, early detection and decision-making, each aimed at solving a real epidemiological problem in the field of animal health. This thesis is multidisciplinary in its approach and its scope: it combines methodologies in mathematics, statistics and computing to generate models useful to epidemiological and veterinary sciences.
The first tool developed in this thesis is based on a three-level deterministic numerical model to assess the risk of introducing vector-borne diseases by simulating wind-borne transport of insects from infected areas.
The second tool is a motion-based monitoring system that allows the detection of significant changes in the behavior of animals that develop febrile disease through computer vision techniques.
The third tool, called Be-FAST (Between and within Farm Animal Spatial Transmission), uses Monte Carlo methods to generate different scenarios of disease spread within and between farms based on the integration of stochastic variables.
