| deployable molecular detection of arboviruses in the australian outback. | the most common causes of human infection from the arboviruses that are endemic in australia are the arthritogenic alphaviruses: ross river virus (rrv) and barmah forest virus (bfv). the most serious infections are caused by the neurotropic flaviviruses, murray valley encephalitis virus (mvev) and the kunjin subtype of west nile virus. the greatest individual risk of arbovirus infection occurs in tropical/subtropical northern australia because of the warm, wet summer conditions from december to ... | 2016 | 27402516 |
| arboviral diseases and malaria in australia, 2009-10: annual report of the national arbovirus and malaria advisory committee. | the national notifiable diseases surveillance system received 7,609 notified cases of disease transmitted by mosquitoes for the season 1 july 2009 to 30 june 2010. the alphaviruses barmah forest virus and ross river virus, accounted for 6,546 (79%) of these notifications during the 2009-10 season. there were 37 notifications of dengue virus infection locally-acquired from north queensland and 581 notified cases in australia that resulted from overseas travel. this number of overseas acquired cas ... | 2012 | 23153083 |
| efficacy of residual insecticide biflex aquamax applied as barrier treatments for managing mosquito populations in suburban residential properties in southeast queensland. | the pyrethroid insecticide biflex aquamax (bifenthrin) was evaluated for its ability to suppress coastal mosquito populations in a controlled suburban backyard study in mango hill, queensland, australia. the insecticide was applied to perimeter vegetation, fencing in selected backyards, or both, and mosquito populations were monitored weekly from 3 wk before to 8 wk after treatment (11 wk total) by using cdc miniature light traps and human bait landing rates. in addition, bioassays were conducte ... | 2012 | 23025182 |
