| isolation of sindbis (alphavirus) and leanyer viruses from mosquitoes collected in the northern territory of australia, 1974. | mosquitoes collected near darwin, northern territory, in 1974 yielded two virus strains. one was identified as sindbis virus, not previously isolated from the northern territory. the other is antigenically distinct from viruses previously isolated from arthropods in australia, and the name "leanyer" is proposed for it. its properties suggest that it may be a togavirus serologically unrelated to available alphaviruses and flaviviruses. | 1977 | 23749 |
| the molecular epidemiology of kokobera virus. | we describe herein the molecular epidemiology and phylogeny of kokobera (kok) virus, a flavivirus found in australia and papua new guinea. we sequenced a region encompassing the 200 nucleotides of the 3' terminus of the ns5 gene, and the first 300 nucleotides of the 3' untranslated region (utr). the study included 25 isolates of the virus, including an isolate from png, and several recent isolates from the south-west of western australia (wa), where the virus had not previously been detected. we ... | 2000 | 10930658 |
| rainfall and vector mosquito numbers as risk indicators for mosquito-borne disease in central australia. | there have been 5 confirmed cases of murray valley encephalitis virus (mve) infection in the alice springs region during the high rainfall years of 1999/00 and 2000/01, compared with one case in the preceding 9 years. there also appeared to be an increased prevalence of ross river virus (rr) infection in the alice springs and tennant creek regions associated with high rainfall. this paper presents an analysis of summer rainfall from 1990/91 to 2000/01, numbers of seroconversion of sentinel chick ... | 2003 | 12725512 |
| arbovirus models to provide practical management tools for mosquito control and disease prevention in the northern territory, australia. | ross river virus (rrv) causes the most common human arbovirus disease in australia. although the disease is nonfatal, the associated arthritis and postinfection fatigue can be debilitating for many months, impacting on workforce participation. we sought to create an early-warning system to notify of approaching rrv disease outbreak conditions for major townships in the northern territory. by applying a logistic regression model to meteorologic factors, including rainfall, a postestimation analys ... | 2011 | 21485389 |
| arboviruses recovered from sentinel livestock in northern australia. | over 700 arboviruses were recovered between 1981 and 1987 from the blood of sentinel livestock near darwin. twenty-three isolates were made from sheep, goats, swamp buffalo (bubalus bubalis) and horses, and the remainder were from cattle. the isolates have been typed as 27 separate viruses belonging to the bluetongue, epizootic haemorrhagic disease, palyam, simbu, bovine ephemeral fever, tibrogargan and alphavirus groups. ten of these viruses have not been isolated elsewhere in australia and fou ... | 1988 | 3218073 |
| vector competence of culex pipiens quinquefasciatus for murray valley encephalitis, kunjin, and ross river viruses from australia. | australian populations of culex pipiens quinquefasciatus say from brisbane, charleville, cairns, kowanyama (queensland), darwin (northern territory), mildura (victoria), and port hedland (western australia) proved to be either poorly susceptible or refractory to oral infection with low passage level murray valley encephalitis, kunjin, and ross river viruses. with respect to past or future epidemics of murray valley encephalitis or kunjin (both known to cause clinical encephalitis in man), and of ... | 1982 | 6285750 |
| the viruses of australia and the risk to tourists. | australia is a climatically diverse country varying from a tropical climate in the north to arid central desert and grassland regions, and to temperate climates in the south. there are many viral infections found in australia that are common to developed countries worldwide, but this article will focus on those that pose a special risk for travellers to australia, especially the mosquito-borne viruses. the commonest are the members of the alphavirus genus, particularly ross river virus and barma ... | 2011 | 21679887 |
| ross river virus infection in a traveller returning from northern australia. | ross river virus is an arthropod-borne alphavirus (family togaviridae) causing epidemic polyarthritis in the australia-pacific region. the infection causes substantial morbidity due to long-lasting arthralgia. despite being the most common arboviral infection in australia, reports in travellers are scarce. here, we describe the disease in a german traveller who was not aware of the prevalence of this infection in his holiday destination, the northern territory and queensland, australia. the pati ... | 2009 | 19727811 |
| ross river virus and barmah forest virus infections: a review of history, ecology, and predictive models, with implications for tropical northern australia. | the purpose of the present article is to present a review of the ross river virus (rrv) and barmah forest virus (bfv) literature in relation to potential implications for future disease in tropical northern australia. ross river virus infection is the most common and most widespread arboviral disease in australia, with an average of 4,800 national notifications annually. of recent concern is the sudden rise in bfv infections; the 2005-2006 summer marked the largest bfv epidemic on record in aust ... | 2008 | 18279007 |
| [arthralgia and rash from australia caused by ross river virus]. | a 58-year-old entomologist presented with disabling arthralgia after a recent visit to the northern territory of australia. a faint maculopapular rash was noticed on the trunk and limbs. the presumptive diagnosis of rrv disease was confirmed by the finding of igm and igg antibodies against rrv in serum. rrv, a mosquito-transmitted alpha virus, is the most common cause of arboviral disease in australia. this disease, initially referred to as epidemic polyarthritis, is characterised by joint pain, ... | 2003 | 12621981 |
| predictive indicators for ross river virus infection in the darwin area of tropical northern australia, using long-term mosquito trapping data. | to describe the epidemiology of ross river virus (rrv) infection in the endemic darwin region of tropical northern australia and to develop a predictive model for rrv infections. | 2008 | 18482196 |
| communicable diseases network australia national arbovirus and malaria advisory committee annual report, 2006-07. | this report describes the epidemiology of mosquito-borne disease in australia for the mosquito-borne disease season 1 july 2006 to 30 june 2007, which was moderately low compared to previous seasons. ross river virus (rrv) infections (55%), barmah forest virus (bfv) infections (29%) and overseas acquired malaria (11%) were the most common mosquito-borne diseases reported in 2006-07. the number, proportion and rate of national bfv notifications were the second highest on record since 1998-99. the ... | 2008 | 18522303 |
