• Where is Malaria ?

    Malaria is a very old disease and prehistoric man is thought to have suffered from malaria. It probably originated in Africa and accompanied human migration to the Mediterranean shores, India, and South East Asia. In the past it used to be common in the marshy areas around Rome and the name is derived from the Italian, (mal-aria) or "bad air" ; it was also known as Roman fever.

  • Atmosphere, diseases and monitoring from space

    During the 21st Century, CO2 concentration in the atmosphere is to increase considerably causing global temperature increase. Few degrees increase in the atmosphere can have serious consequences on public health and diseases re-emergence and diffusion. For example, tropical diseases could increase in mid-latitudes, since mosquitoes and other disease-carrying insects may found appropriate climate and environment.
    Warming/cooling trends can be due also to natural cycles or low-frequency (...)

  • Climate/ environment and Rift Valley Fever

    Incidence of climate and environment on human health is well-known. Local climate conditions have biological implications on some diseases vectors and can modulate the Extrinsic Incubation Period (EIP) of vectors as well as behavior of pathogenic agents.
    Satellites monitoring from space agencies such as CNES, CONAE, and NASA among others, with derived added-values products and analyses, can help providing real-time climate and environment variability possibly linked to epidemics’ risks. (...)
