Rift Valley Fever Seroprevalence in Kenyan Livestock (2013 Survey)

Environmental Information Data Centre provides seroprevalence data from a 2013 cross-sectional survey of 460 cattle, 949 goats, and 574 sheep in Tana River County, Kenya. The dataset combines serological test results for anti-Rift Valley Fever virus IgG with household-level and animal-level variables. Field surveys were implemented from August to November 2013, with laboratory analyses completed in June 2015.

Use Cases

• Model Rift Valley Fever virus exposure risk using serological results, animal breed, age, and sex.
• Analyze the effect of land use (irrigated vs. non-irrigated areas) on seroprevalence patterns across livestock species.
• Investigate correlations between household livestock ownership totals, geographical coordinates, and animal-level body condition scores.
• Map seroprevalence against sampling site altitude and geographical coordinates to identify spatial risk factors.

Strengths

• Includes data from 1,983 total animal serum samples (460 cattle, 949 goats, 574 sheep).
• Integrates serological lab results with field-collected household and animal-level variables.
• Clear temporal scope with field surveys in 2013 and lab completion in 2015.
• Collected by experienced researchers from the Ministry of Livestock Development and the International Livestock Research Institute.

Limitations

• Sample size is moderate and confined to a single county in Kenya, limiting generalizability.
• Data is from a 2013 survey and may not reflect current seroprevalence or environmental conditions.
• Unknown column structure and potential for missing data points not detailed in the description.
