Heartworm Transmission Risk Factors for Dogs in Iberian Peninsula and Islands, 2023-2024

Spain and Portugal data from 3,670 antigen-positive dogs collected between 2023 and 2024. Rodrigo Morchón analyzed geographic, climatic, and host-related factors associated with Realized Transmission Risk (RTR) using an Ecological Niche Model. The findings suggest transmission is shaped by geographic, climatic, and anthropogenic interactions, with high risk in insular territories and hot semi-arid climates.

Use Cases

• Modeling disease risk based on geographic region and climatic classifications mentioned in the description
• Assessing the impact of indoor versus outdoor dog housing on parasite exposure risk
• Analyzing temporal trends in transmission risk based on the 2024 data increase
• Developing One Health prevention strategies for insular and semi-arid areas

Strengths

• Includes 3,670 antigen-positive canine cases
• Integrates an Ecological Niche Model for Culex pipiens with parasite development thresholds
• Analyzes data from a specific time range (2023–2024)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the Iberian Peninsula study area
