In January 2005, an epidemic of chikungunya fever broke out in the Comoro Islands and lasted until May 2005. In April, cases were also reported in Mayotte and Mauritius. On Réunion Island, the first cases were reported at the end of April. Surveillance of this epidemic required an adaptive system, which at first was based on active and retrospective case(More)
AIMS AND METHODS Long term effects of air pollution on mortality were studied in 14,284 adults who resided in 24 areas from seven French cities when enrolled in the PAARC survey (air pollution and chronic respiratory diseases) in 1974. Daily measurements of sulphur dioxide, total suspended particles, black smoke, nitrogen dioxide, and nitric oxide were made(More)
Given the hypothesis that particulate air pollution is associated with systolic blood pressure, the effect of daily concentrations of air pollution on blood pressure was assessed in 2612 elderly subjects in the urban area of Bordeaux, France. Blood pressure was measured by a digital monitor. Particle concentrations (PM10) were obtained from the AIRAQ(More)
The Phytoner study investigated a possible association between neuropsychologic performances and long-term exposure to pesticides in Bordeaux vineyard workers, most of whom use fungicides. Among the 917 subjects interviewed from February 1997 to August 1998, 528 were directly exposed to pesticides through mixing and/or spraying (mean exposure duration: 22(More)
Current knowledge about potential interactions between socioeconomic status and the short- and long-term effects of air pollution on mortality was reviewed. A systematic search of the Medline database through April 2006 extracted detailed information about exposure measures, socioeconomic indicators, subjects' characteristics and principal results. Fifteen(More)
On Reunion Island, in response to the threat of emergence of the pandemic influenza A(H1N1)2009 virus, we implemented enhanced influenza surveillance from May 2009 onwards in order to detect the introduction of pandemic H1N1 influenza and to monitor its spread and impact on public health. The first 2009 pandemic influenza A(H1N1) virus was identified in(More)
PAQUID is an epidemiological cohort which aims to study cerebral and functional factors of ageing. We have examined the relationship between dyspnea level at entrance into this cohort and mortality occurring during the subsequent 8 years. Dyspnea was evaluated by a questionnaire derived from a Fletcher's five-degree scale. Mortality was recorded during(More)
BACKGROUND During August 2003, record high temperatures were observed across Europe, and France was the country most affected. During this period, elevated ozone concentrations were measured all over the country. Questions were raised concerning the contribution of O3 to the health impact of the summer 2003 heat wave. METHODS We used a time-series design(More)
BACKGROUND Facemasks and respirators have been stockpiled during pandemic preparedness. However, data on their effectiveness for limiting transmission are scarce. We evaluated the effectiveness of facemask use by index cases for limiting influenza transmission by large droplets produced during coughing in households. METHODOLOGY AND PRINCIPAL FINDINGS A(More)
BACKGROUND In 2005-2006, a major epidemic of CHIKV infection occurred in the Islands of the south-western Indian Ocean, and longstanding manifestations seemed to be more frequent than described before. OBJECTIVES To describe the frequency and related factors of late clinical manifestations of CHIKV infection among imported cases living in Aquitaine area,(More)
