| protective behavior survey, west nile virus, british columbia. | we investigated personal protective behaviors against west nile virus infection. barriers to adopting these behaviors were identified, including the perception that deet (n,n-diethyl-m-toluamide and related compounds) is a health and environmental hazard. televised public health messages and knowing that family or friends practiced protective behaviors were important cues to action. | 2004 | 15496260 |
| predicting outbreaks: a spatial risk assessment of west nile virus in british columbia. | west nile virus (wnv) has recently emerged as a health threat to the north american population. after the initial disease outbreak in new york city in 1999, wnv has spread widely and quickly across north america to every contiguous american state and canadian province, with the exceptions of british columbia (bc), prince edward island and newfoundland. in this study we develop models of mosquito population dynamics for culex tarsalis and c. pipiens, and create a spatial risk assessment of wnv pr ... | 2006 | 16704737 |
| notes on the distribution of mosquito species that could potentially transmit west nile virus on vancouver island, british columbia. | we record the spatial and temporal distribution of 8 potential vectors of west nile virus (wnv) on vancouver island in 2003 and 2004. five species were widely distributed, but the other 3 were restricted to specific larval habitats. adults were trapped from early april to september. the findings indicate a potential for wnv transmission if the virus arrives on the island. the results extend the published range of 5 mosquito species. | 2006 | 17067062 |
| a bird's eye view: using geographic analysis to evaluate the representativeness of corvid indicators for west nile virus surveillance. | the objective of this evaluation was to determine whether reports of dead corvid sightings and submissions of dead corvids for west nile virus testing were representative of true corvid mortality in british columbia in 2004, a year with no west nile virus activity, in order to ensure the system was accurately describing corvid mortality rather than reflecting regional differences in surveillance methods. | 2007 | 17263891 |
| use of geographic information systems to assess the feasibility of ground- and aerial-based adulticiding for west nile virus control in british columbia, canada. | geographic information systems (gis) analysis of 34 forecasted high west nile virus (wnv) risk communities in british columbia (bc), canada was useful to assess feasibility and planning of the operational logistics of an emergency spray event in advance of a wnv outbreak. the geographic coverage and operational time required to perform ground- and aerial-based ultra-low volume (ulv) adulticiding were calculated using gis. the mean geographic coverages of the ground-, aerial-, and combination of ... | 2007 | 18240516 |
| communicating the risks of a new, emerging pathogen: the case of cryptococcus gattii. | the news media are an important channel for communicating public health messages, providing important information about geographic extent, symptoms, and precautionary measures. this function may be particularly important in the case of new and emerging infectious diseases, which are unfamiliar to both the public and health professionals. we conducted a content analysis of the coverage in six canadian newspapers of two emerging infectious pathogens in british columbia (bc), west nile virus and cr ... | 2008 | 18419655 |
| west nile virus range expansion into british columbia. | in 2009, an expansion of west nile virus (wnv) into the canadian province of british columbia was detected. two locally acquired cases of infection in humans and 3 cases of infection in horses were detected by elisa and plaque-reduction neutralization tests. ten positive mosquito pools were detected by reverse transcription pcr. most wnv activity in british columbia in 2009 occurred in the hot and dry southern okanagan valley. virus establishment and amplification in this region was likely facil ... | 2010 | 20678319 |
| infections in the natural environment of british columbia, canada. | the canadian province of british columbia has a luxurious environment, complete with the multitude of wildlife and insects, and would at first glance appear to be suitable for the transmission of diseases in nature communicable to humans. despite this potential, such diseases are relatively uncommon, although several have the potential for serious consequences. attention has been recently focused on hantavirus infection, water-borne toxoplasmosis and parasitic diarrheal diseases, cryptococcosis ... | 2008 | 20701841 |
| west nile virus finally debuts in british columbia 10 years after its introduction to north america. | abstract since its first detection in new york (1999), west nile virus (wnv) has spread across the united states and canada with the first activity reported in canada in 2001. by 2004, wnv had been detected almost in every province of canada and the contiguous regions of the united states with the exception of british columbia (bc), this despite being detected in alberta in 2003 and washington as early as 2002. in august 2009, two human cases were serologically found to have wnv infection. they ... | 2010 | 21028958 |
