[leptospirosis and environment. study of 2 major foci in new caledonia].a study of human and animal leptospirosis was carried out in new caledonia's two most important focuses. this survey showed an annual incidence in the human population of 8.8 p. thousand in the nera basin and 0.88 p. thousand in the coulée basin. male adults with agricultural and livestock occupations are the most exposed, especially from march to may, the end of the hot season. frequent contacts with fresh water and animals, and the failure to use of gloves and boots, significantly increase the ...19883231845

[human leptospiroses in the overseas departments and territories: 10 years' immunological diagnosis (1970-1979)].in french overseas departments and territories, leptospiroses exist. in the caribbean zone, human leptospiroses are frequently found; in martinique island, and some cases are recorded in french guyana. in the indian ocean, "la réunion" island, approximately 40 cases are diagnosed every year (mortality rate: 17%). in polynesian areas, 3 serovars are found. biological diagnosis is easier now with screening tests. sera are to be sent to the national leptospirosis centre, paris, for confirmatory tes ...19807226358
public health importance of human leptospirosis in the south pacific: a five-year study in new caledonia.a retrospective study of 192 cases of human leptospirosis in new caledonia (south pacific) diagnosed between 1989 and 1993 showed that the disease was endemic throughout the territory. the annual incidence rate was 30 per 100,000 population, and the disease was more frequent in males (67.5%). cases occurred mainly in march each year. forty isolates were obtained (20.8%) and identified as belonging to serovars icterohaemorrhagiae (28), pomona (6), pyrogenes (3), ballum (2), and javanica (1). most ...19968780456
epidemiology of leptospirosis in new caledonia (south pacific): a one-year survey.we describe a series of 144 cases of leptospirosis diagnosed in 1989 in new caledonia. the incidence rate was 90 per 100,000 person-years, with a specific mortality rate of 4% patients. those affected (100 males, 44 females) were mainly aged 20 to 40 years. incidence in rural areas (112 per 100,000 person-years) was seven times higher than in urban settlements. two periods with higher incidence were noticed corresponding to highest rainfall. twenty-nine of the cases occurred in individuals with ...19979084999
clinical aspects of ocular leptospirosis in new caledonia (south pacific).the incidence of leptospirosis is very high in new caledonia (average annual incidence rate: 180/100 000 of the population). to investigate the role of pathogenic leptospires as an aetiological agent of ocular diseases, we report the results of a 5-year survey in new caledonia.199910641895
rapid leptospira identification by direct sequencing of the diagnostic pcr products in new caledonia.most of the current knowledge of leptospirosis epidemiology originates from serological results obtained with the reference microscopic agglutination test (mat). however, inconsistencies and weaknesses of this diagnostic technique are evident. a growing use of pcr has improved the early diagnosis of leptospirosis but a drawback is that it cannot provide information on the infecting leptospira strain which provides important epidemiologic data. our work is aimed at evaluating if the sequence poly ...201021176235
rodent abundance dynamics and leptospirosis carriage in an area of hyper-endemicity in new caledonia.widespread but particularly incident in the tropics, leptospirosis is transmitted to humans directly or indirectly by virtually any mammal species. however, rodents are recognized as the most important reservoir. in endemic regions, seasonal outbreaks are observed during hot rainy periods. in such regions, hot spots can be evidenced, where leptospirosis is "hyper-endemic", its incidence reaching 500 annual cases per 100,000. a better knowledge of how rodent populations and their leptospira preva ...201122039557
[epidemiological study of leptospirosis in new caledonia].this epidemiological survey includes the study of human and animal leptospirosis in new caledonia from clinical cases as well as a systematic serological study about exposed human and animal populations. the results show that this disease is endemic on the whole territory with a few important focuses in agricultural area, especially on the western coast. leptospira icterohemorrhagiae is the main serotype and is responsible for serious human leptospirosis. the male farmers constitute the most exp ...19883416406
outbreak of leptospirosis in new caledonia: diagnosis issues and burden of disease.a leptospirosis epidemic affected new caledonia during the first semester of 2008. a total of 135 cases were diagnosed with a relatively low fatality rate of 3.7%. heavy rainfalls, related to la niña, favoured this epidemic. the pcr, routinely used, confirmed 54% of the cases, and the microagglutination test 56%. epidemiological and economical data on this epidemic are presented and discussed.200919552660
[laboratory based human leptospirosis surveillance in new caledonia (2001-2005)].the pasteur institute in new caledonia performs for this territory the biological diagnosis of human leptospirosis; therefore its activity locally gives a rather exhaustive description of this pathology. the results presented here cover the 2001-2005 period and describe the principal epidemiological and biological features of human leptospirosis in new caledonia. the investigated patients were recruited by the main medical structures: territorial and provincial hospitals, public dispensaries, cl ...200717727039
