| west nile virus, guadeloupe. | to determine whether west nile virus (wnv) had reached the archipelago of guadeloupe, a serologic study in horses and birds was conducted in 2002. immunoglobulin (ig) g, igm, enzyme-linked immunosorbent assay, and seroneutralization tests identified wnv infection in horses and chickens. six months later, a high rate of seroconversion was observed in horses. | 2004 | 15200864 |
| west nile virus surveillance, guadeloupe, 2003-2004. | we conducted extensive surveillance for west nile virus infection in equines and chickens in guadeloupe in 2003-2004. we showed a high seroprevalence in equines in 2003 related to biome, followed by a major decrease in virus circulation in 2004. no human or equine cases were reported during the study. | 2005 | 16022789 |
| west nile virus in guadeloupe: introduction, spread, and decrease in circulation level: 2002-2005. | in july 2002, a surveillance system was implemented on guadeloupe to detect for the potential introduction and monitor the spread of west nile virus (wnv). from 2002 to 2004, equines and chickens were serologically assayed for antibodies to wnv by igg and igm enzyme-linked immunosorbent assay (elisa), epitope-blocking elisa, and plaque reduction neutralization tests. after introduction, probably through migratory birds at the end of 2001, many seroconversions occurred between july and october 20 ... | 2006 | 17135513 |
| changes in epidemiology of leptospirosis in 2003--2004, a two el niño southern oscillation period, guadeloupe archipelago, french west indies. | our study aimed at analysing the changes in epidemiological features of leptospirosis cases from the hospital of pointe à pitre in guadeloupe in 2003--2004 compared to reliable data in 1994--2001. leptospirosis incidence increased fourfold during 2002--2004, a period with two el niño events. whereas the main risk factors were unchanged (male gender, occupational exposure, contact with cattle or pigs) a major role of rodent exposure emerged (52%, p=0.02, multivariate analysis). interestingly, mea ... | 2008 | 18096102 |
| risk factors for west nile virus seropositivity of equids in guadeloupe. | in guadeloupe, west nile virus (wnv) activity was first observed in equids in 2002, and a high seroprevalence was found in 2003. the objective of our study was to determine individual and environmental factors associated with the risk of wnv seropositivity during 2002-2003. fieldwork was conducted to retrospectively determine the location of equids at the time of virus circulation and to collect information regarding environmental and individual variables. sera were collected from 369 equids out ... | 2009 | 19664833 |
