Introduction: Human rabies is a major public health problem in many African countries, including Côte d’Ivoire. the present work aims at describing the eco-epidemiological characteristics of human rabies cases recorded in Côte d’Ivoire. Methods: this was a retrospective and prospective cross-sectional descriptive study based on epidemiological surveillance data that ran from september 2014 to december 2017. the clinical data were extracted from the database of the human rabies epidemiological surveillance management service of the National Institute of Public Hygiene’s rabies centre. these data cover the period from 1 January 2012 to 31 December 2017. Results: Human rabies is endemic in Côte d’Ivoire, with most people exposed in the south and especially in the west of the country. there was no association between any of the climatological parameters (temperature, humidity, rainfall) and the occurrence of human rabies during the months of exposure to rabies infection. Conclusion: Ultimately, effective prevention and control of human rabies requires a thorough understanding of the links between climatological parameters and rabies. Health authorities must take ownership of these results if we are to achieve our goal of eliminating rabies by 2030.

ICRF Experiments and Potential Formation on the GAMMA 10 tandem Mirror

target plasmas, on which the formation of the electrostatic potentials and the improvement of the confinement are studied, are produced with ICRF in the GAMMA 10 tandem mirror. the ion temperature of more than 10 keV has been achieved in relatively low density plasmas. When the strong ICRF heating is applied, it is observed that the high frequency and the low frequency fluctuations are excited and suppress the increase of the plasma parameters. Recently, a new high power gyrotron system has been constructed and the ECRH power in plug extends up to 370 kW. the improvement of the confinement due to the formation of the potential in the axial direction and the strong radial electric field shear has been observed.
