    This paper presents an analysis of the interaction between the various variables associated with Rift Valley fever (RVF) such as the mosquito vector, available hosts and rainfall distribution. To that end, the varying zones potentially occupied by mosquitoes (ZPOM), rainfall events and (...)

  • Mapping of zones potentially occupied by Aedes vexans and Culex poicilipes mosquitoes, the main vectors of Rift Valley Fever in Senegal

    Abstract. A necessary condition for Rift Valley fever (RVF) emergence is the presence of Aedes (Aedimorphus) vexans and Culex (Culex) poicilipes mosquitoes carrying the arbovirus and responsible for the infection. This paper presents a detailed mapping in the Sahelian region of Senegal of zones potentially occupied by these mosquitoes (ZPOMs) (...)

    The abundance of mosquitoes around ponds is essentially linked to the intraseasonal variability of rainfall which can be modulated by a panoply of climate signals. Larvae sites for the Aedes vexans and Culex poicilipes can thus proliferate (...)

  • Mapping Rift Valley fever and malaria risk over West Africa using climatic indicators

    Extract of ATMOSPHERIC SCIENCE LETTERS - 18 August 2010
    Published online in Wiley Online Library DOI : 10.1002/asl.296
