Environmental and ecological determinants of West Nile virus occurrence in horses in North Dakota, 2002.

Abstract: West Nile virus (WNV) outbreak in North Dakota in 2002 included over 569 horse cases, clustered mainly in the eastern and northeastern parts of the state. The pattern of occurrence observed suggested existence of specific environmental and ecological factors that increased the risk for infection and illness in those locations. We developed a predictive model with factors that explained the pattern of WNV occurrence observed. Results indicated that surface elevation, temperature, precipitation, reported WNV-positive birds, reported WNV-positive humans, and reported WNV-positive mosquitoes were important predictors of occurrence in horses. However, case distance from water bodies was not significant in the model. Future predictive models of WNV occurrence in horses should take into account these factors in order to improve accuracy and reliability. Research into other potential determinants such as horse management factors are required to determine more differential risk factors associated with WNV occurrence in horses.

The research paper discusses a study conducted to identify the environmental and ecological factors influencing the outbreak of West Nile Virus (WNV) in horses in North Dakota in 2002. The researchers built a predictive model incorporating these factors to explain the patterns of WNV occurrence in horses.

Research Context and Purpose

  • The study was conducted in the context of a major West Nile virus outbreak in North Dakota in 2002, where over 569 horse cases were reported.
  • The aim of the research was to identify the specific environmental and ecological factors that made certain locations more susceptible to WNV infection, as suggested by the clustering of cases mainly in the eastern and northeastern parts of the state.

Predictive Model Development and Factors Considered

  • The researchers developed a predictive model to explain the patterns of WNV occurrence in horses based on certain factors.
  • The factors included in the model were surface elevation, temperature, precipitation, reported WNV-positive birds, humans, mosquitoes, and the case distance from water bodies.
  • The model aimed at predicting WNV occurrence in horses using these factors.

Results of the Study

  • The results from the predictive model highlighted surface elevation, temperature, precipitation, the presence of WNV-positive birds, humans and mosquitoes as significant determinants of WNV occurrence in horses.
  • The case distance from water bodies did not significantly contribute to the model, thus was not considered as a significant determinant of WNV outbreak in horses.

Implications and Recommendations

  • The study suggests that future predictive models of WNV occurrence in horses can improve their accuracy and reliability by considering the highlighted factors.
  • Further research is recommended to investigate other potential determinants such as horse management factors, which could help identify more definitive risk factors associated with WNV occurrence in horses.
