| vectors vs. humans in australia--who is on top down under? an update on vector-borne disease and research on vectors in australia. | australia has a diversity of vectors and vector-borne human diseases. mosquito-borne arboviruses are of greatest concern, but there are issues with other vector and pathogen systems. mosquitoes were responsible for more than 35,000 cases of ross river virus during 1991-1997. barmah forest virus is increasing nationwide, and unidentified bunyaviruses suspected of causing illness have been isolated. cases of murray valley encephalitis have occurred in 14 of the past 20 years in northern australia. ... | 1998 | 9673928 |
| [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 |

| 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 |
| 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 |
| 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 |
| a geospatial evaluation of aedes vigilax larval control efforts across a coastal wetland, northern territory, australia. | adjacent to the northern suburbs of darwin is a coastal wetland that contains important larval habitats for aedes vigilax (skuse), the northern salt marsh mosquito. this species is a vector for ross river virus and barmah forest virus, as well as an appreciable human pest. in order to improve aerial larval control efforts, we sought to identify the most important vegetation categories and climatic/seasonal aspects associated with control operations in these wetlands. by using a generalized linea ... | 2009 | 20836835 |
| 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 |
| 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 |
| applications of a sugar-based surveillance system to track arboviruses in wild mosquito populations. | effective arbovirus surveillance is essential to ensure the implementation of control strategies, such as mosquito suppression, vaccination, or dissemination of public warnings. traditional strategies employed for arbovirus surveillance, such as detection of virus or virus-specific antibodies in sentinel animals, or detection of virus in hematophagous arthropods, have limitations as an early-warning system. a system was recently developed that involves collecting mosquitoes in co2-baited traps, ... | 2014 | 24359415 |
| an overview of the epidemiology of notifiable infectious diseases in australia, 1991-2011. | we reviewed the first 21 years (1991-2011) of australia's national notifiable diseases surveillance system (nndss). all nationally notified diseases (except hiv/aids and creutzfeldt-jakob disease) were analysed by disease group (n = 8), jurisdiction (six states and two territories), indigenous status, age group and notification year. in total, 2 421 134 cases were analysed. the 10 diseases with highest notification incidence (chlamydial infection, campylobacteriosis, varicella zoster, hepatitis ... | 2016 | 27586156 |
| determining culex annulirostris larval densities and control efforts across a coastal wetland, northern territory, australia. | the darwin coastal wetlands provide suitable breeding conditions for culex annulirostris, which is abundant between december and august each year. this species is the principal vector for arboviruses, including ross river virus and murray valley encephalitis, and is an appreciable pest species. aerial control is conducted when routine larval surveys for this species predict high numbers of emergent adults. we sought to determine the most productive vegetation categories and seasonal aspects asso ... | 2016 | 27860005 |
