Outbreaks of African horse sickness in Senegal, and methods of control of the 2007 epidemic.

Abstract: Since first being detected in Nigeria in January 2007, African horse sickness virus serotype 2 (AHSV-2) has spread throughout the northern hemisphere, and was first reported in Senegal. A retrospective study was conducted from December 2009 to April 2010 using data collected in the field combined with information available at the Direction of Veterinary Services. The epidemic started in the Dakar region with two outbreaks in March and June 2007, respectively, and spread in several parts of the country between July and November 2007. During this period, 232 outbreaks and 1137 horse deaths were reported. The epidemic was controlled by mass vaccination using a polyvalent-attenuated vaccine. This retrospective study was conducted with various assumptions of AHSV-2 introduction, and provides recommendations for implementing an early warning surveillance system for African horse sickness in Senegal.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article discusses the spread and control of the African horse sickness virus serotype 2 (AHSV-2) that began in Nigeria in January 2007 and hit Senegal later that year. By using field data and a retrospective study, the researchers were able to trace the virus spread with mass vaccination being the primary method of controlling the epidemic.

Research Methodology and Findings

  • The research was a retrospective study that utilized data collected from the field, in conjunction with information obtained from the Direction of Veterinary Services. This study took place from December 2009 to April 2010.
  • It was found that the epidemic started in the Dakar region with two initial outbreaks reported in March and June of 2007. From there, the disease spread to various parts of the country between July and November of the same year.
  • During the escalation of the epidemic, there were 232 reported outbreaks and 1,137 horse deaths. The widespread and rapid transmission of the virus showcased its severity and the urgent need for containment and management measures.

Control Measures and Recommendations

  • The epidemic was primarily controlled through the application of mass vaccination, which used a polyvalent (effective against different strains of the disease) attenuated (weakened) vaccine.
  • The authors also conducted the retrospective study under varying assumptions about the introduction of AHSV-2 into the population, which enabled them to simulate potential reactions and response strategies under different scenarios.
  • Based on their extensive analysis, the study offers recommendations for establishing an early warning surveillance system for African horse sickness in Senegal. This system would enable quicker and more effective responses to future outbreaks, and potentially save more horses from falling victim to the disease.
