Land Use Change, Transmission Potential Networks and Disease Spread in Madagascar.

Land Use Change, Transmission Potential Networks and Disease Spread in Madagascar.

Funded by the Ecology and Evolution of Infectious Disease Program (NIH, $2,451,309)

This highly interdisciplinary team of natural and social scientists investigates anthropogenic land use and its impact on infectious disease transmission among humans and animals in Madagascar.  We are:

  • Using network science and geographic approaches to model transmission pathways in rural communities.
  • Testing whether the transmission pathways explain patterns of infection.
  • Identifying the factors that influence the contact patterns, which is crucial for understanding social networks and controlling disease transmission.
  • Investigating the role of land use change and small mammal communities (especially rats) on human infectious disease risk.
