In April 2005, an outbreak of Chikungunya fever occurred on the island of Réunion in the Indian Ocean. During winter 2005, six patients developed meningoencephalitis and acute hepatitis due to Chikungunya virus. Our objectives were to determine the incidence and mortality of atypical Chikungunya viral infections and to identify risk factors for severe(More)
During the summer of 2014, all the pre-requisites for autochthonous transmission of chikungunya virus are present in southern France: a competent vector, Aedes albopictus, and a large number of travellers returning from the French Caribbean islands where an outbreak is occurring. We describe the system implemented for the surveillance of chikungunya and(More)
From 1994 to 2009, national field epidemiology training programmes (FETP) have been installed in Spain, Germany, Italy, France and Norway. During their two year duration, different components of the FETP are devised as follows: 63-79 weeks are spent on projects in hosting institutes, 2-26 weeks in outside projects, 9-30 weeks in courses and modules, and 1-2(More)
Sera collected in May 1984 from 132 adult residents of Karamoja district, Uganda, were examined by haemagglutination inhibition tests for antibodies against selected arboviruses, namely Chikungunya and Semliki Forest alphaviruses (Togaviridae); dengue type 2, Wesselsbron, West Nile, yellow fever and Zika flaviviruses (Flaviviridae); Bunyamwera, Ilesha and(More)
A cluster sample survey was conducted in January 1989 in 3 provinces of Burkina Faso to evaluate an immunization programme (based on two contacts, providing inactivated poliomyelitis vaccine plus DPT) that had been launched in 1982-84. The objectives were to estimate neonatal tetanus (NNT) mortality and poliomyelitis prevalence in the study area. The target(More)
Early in the 1980s, those involved in public health held symposiums to assess the training of epidemiologists in France showed inadequacies in the teaching of field epidemiology. Hitherto epidemiology in France had been largely confined to research. Evolution of public health practice, with an increasing demand to base decisions on epidemiological data,(More)
A study of frequency of treponematosis among pregnant women in Mother Hood of Zogbo (Cotonou) shows 5.1 +/- 2.8% of positivity with risk of 5% by TPHA and VDRL. The low level of endemicity, associated with the absence of cutaneous lesions of treponematosis in Cotonou may correspond to a syphilis infection. This study points out the necessity to strengthen(More)
