This research article explores the occurrence and impact of West Nile Virus in equine populations in Egypt. It investigates the role of horses in the transmission and maintenance of the virus in nature, as well as records the isolated case of equine encephalitis resulting from the virus.

Research Context and Background

  • The article starts by outlining the scope and impact of West Nile fever, which is similar to dengue and present in much of Africa, the Middle East, and India.
  • It highlights that the current understanding of the virus’s epidemiology and ecology comes mainly from studies done in Egypt and Israel.
  • The researchers explain that the primary infection cycle involves mosquitoes of the Cu/lex species and various types of birds, with humans and other vertebrates being infected secondarily.
  • Hay discuss that even though secondary infections usually do not contribute to the virus’s spread (referred to as ‘dead end’), the role of non-avian vertebrates has not been adequately studied.

Role of Horses in West Nile Virus Transmission

  • The study notices that the serological surveys carried out previously in the Nile delta show a wide range of vertebrates getting infected. Still, horses show the highest incidence of antibody.
  • This is significant because horses are known to host several arthropod-borne viruses like the eastern, western, Venezuelan, and Japanese encephalitis viruses.
  • Therefore, the researchers felt it was necessary to evaluate the importance of horses in the natural history of West Nile fever.

Research Findings and Experiments

  • The research gives an account of the incidence and distribution of West Nile virus infection in the horse populations of the Nile delta and Upper Egypt.
  • It presents the isolation of the West Nile virus from a case of equine encephalitis in Upper Egypt.
  • The authors summarize the experiments that were designed to clarify the role of horses in the cyclical passage and maintenance of the virus in nature.
