prevalence of west nile virus in wild american kestrels (falco sparverius) of southern quebec, canada.we assessed west nile virus (wnv) antibody prevalence in american kestrels (falco sparverius) in southern quebec by sampling 152 birds during the 2003-05 breeding seasons. we analyzed the dependence of antibody prevalence on age group, year, and gender; a significant relationship was detected only between age (adults vs. nestlings) and antibody prevalence. furthermore, reproductive success did not appear to be linked with the prevalence of anti-wnv antibodies in this population.201020688659
determining the rate of underrecognition of west nile virus neurologic disease in the province of quebec in 2012.during a major outbreak of west nile virus (wnv) infection in the province of quebec in 2012, public health authorities (phas) suspected underrecognition of west nile neurologic disease (wnnd). with data on acute infections detected in blood donors, an estimate of the degree of underrecognition was produced.201728301049
risk factors associated with west nile virus mortality in american crow populations in southern quebec.soon after the appearance of west nile virus (wnv) in north america, a number of public health authorities designated the american crow (corvus brachyrhynchos) a sentinel for wnv detection. although preliminary studies have suggested a positive association between american crow mortality and increased risk of wnv infection in humans, we still know little about dynamic variation in american crow mortality, both baseline levels and mortality associated with wnv. we hypothesized that the complex so ...201020090033
the analysis of crow population dynamics as a surveillance tool.west nile virus (wnv) infection, a zoonotic disease for which birds act as a reservoir, first appeared in north america in august 1999. it was first reported in quebec in 2002. the quebec surveillance system for wnv has several components, including the surveillance of mortality in corvid populations, which includes the american crow (corvus brachyrhynchos). the main objectives of this study are to better understand the population dynamics of this species in quebec and to evaluate the impact of ...200919811623

effects of climate on west nile virus transmission risk used for public health decision-making in 2002, major human epidemics of west nile virus (wnv) were reported in five cities in the north east region of north america. the present analysis examines the climatic conditions that were conducive to the wnv epidemic, in order to provide information to public health managers who eventually must decide on the implementation of a preventive larvicide spraying program in quebec, canada. two sets of variables, the first observed in the summer of 2002 and the second in the preceding winter were ...200717883862
development of three additional culex species-specific polymerase chain reaction primers and their application in west nile virus surveillance in 2002, more than 17,000 mosquito pools collected in canada (quebec, ontario, and manitoba) were tested at the national microbiology laboratory in winnipeg, manitoba, for infection with west nile virus (wnv). using real-time reverse-transcriptase polymerase chain reaction (rt-pcr), 558 mosquito pools (86% culex species and 14% other species) had evidence of infection with wnv. only 30% of the culex specimens, however, were identified to the species level. in this study, culex species-specific p ...201020402349
the geosimulation of west nile virus propagation: a multi-agent and climate sensitive tool for risk management in public health.since 1999, the expansion of the west nile virus (wnv) epizooty has led public health authorities to build and operate surveillance systems in north america. these systems are very useful to collect data, but cannot be used to forecast the probable spread of the virus in coming years. such forecasts, if proven reliable, would permit preventive measures to be put into place at the appropriate level of expected risk and at the appropriate time. it is within this context that the multi-agent geosim ...200818606008

assessing interventions to manage west nile virus using multi-criteria decision analysis with risk scenarios.the recent emergence of west nile virus (wnv) in north america highlights vulnerability to climate sensitive diseases and stresses the importance of preventive efforts to reduce their public health impact. effective prevention involves reducing environmental risk of exposure and increasing adoption of preventive behaviours, both of which depend on knowledge and acceptance of such measures. when making operational decisions about disease prevention and control, public health must take into accoun ...201627494136
characterizing environmental risk factors for west nile virus in quebec, canada, using clinical data in humans and serology in pet dogs.the identification of specific environments sustaining emerging arbovirus amplification and transmission to humans is a key component of public health intervention planning. this study aimed at identifying environmental factors associated with west nile virus (wnv) infections in southern quebec, canada, by modelling and jointly interpreting aggregated clinical data in humans and serological data in pet dogs. environmental risk factors were estimated in humans by negative binomial regression base ...201728835296
