Theia “Risks Associated with Infectious Diseases” scientific expertise centre (SEC) brings together research teams from UMR AstreUMR TetisUMR Espace-Dev, CRC-Université de Bourgogne and  Cnes, all developing transmission risk maps for the various infectious diseases, vector-borne or otherwise, using Earth Observation data.

These products are destined to help spread information on epidemiological risks linked to infectious diseases among public health care players.

Risk maps, modelling and mapping tools and land use maps

The products proposed are risk maps, defined in terms of the probability of cases occurring or the presence of vectors :

  • For various infectious diseases: Nil fever, Rift Valley fever, malaria, dengue or chickungunya
  • For various areas of study (Europe, Africa, South America, Asia and the Indian Ocean)
  • At different space scales
