'''''Ross River virus'''''  ('''RRV''') is a small encapsulated single-strand [[RNA virus|RNA]] ''[[Alphavirus]]'' [[Endemic (epidemiology)|endemic]] to Australia, [[Papua New Guinea]] and other islands in the South Pacific. It is responsible for a type of [[mosquito]]-borne, non-lethal but extremely debilitating [[tropical disease]] known as [[Ross River fever]], previously termed "epidemic [[polyarthritis]]". There is no known cure, and it can last in the host's system for up to 20 years. The virus is suspected to be [[enzootic]] in populations of various native Australian mammals,<ref>Ong OTW, Stephensen EB, Johnson BJ, Old JM (2021).

==Classification and morphology==
[[File:Aedes Mosquito.jpg|thumb|''[[Aedes]]'' mosquito]]
Taxonomically, ''Ross River virus'' belongs to the virus genus ''[[Alphavirus]]'', which is part of the family ''[[Togaviridae]]''. The alphaviruses are a group of small enveloped single-strand positive-sense RNA viruses. RRV belongs to a subgroup of "Old World" (Eurasian-African-Australasian) alphaviruses, and belongs to the SF antigenic complex of the genus Alphavirus.<ref name=Harley/>

The virions (virus particles) themselves contain their genome in a protein capsid 700 [[Angstrom|Å]] in diameter. They are characterised by the presence of two [[glycoproteins]] (E1 and E2) embedded as trimeric dimers in a host-derived lipid [[virus envelope|envelope]].<ref name=panbio>{{cite web|url=http://www.panbio.com.au/modules.php?name=Content&pa=showpage&pid=38 |title=Ross River fever |publisher=[[Panbio Diagnostics]] |access-date=29 October 2008 |url-status=dead |archive-url=https://web.archive.org/web/20080925113853/http://www.panbio.com.au/modules.php?name=Content&pa=showpage&pid=38 |archive-date=25 September 2008 }}</ref>

Because RRV is transmitted by [[mosquito]]s, it is considered an [[arbovirus]], a non-taxonomic term for viruses borne by arthropod [[Vector (epidemiology)|vector]]s.

==History==
In 1928, an outbreak of acute febrile arthritis was recorded in [[Narrandera]] and [[Hay, New South Wales|Hay]] in [[New South Wales]], Australia. In 1943, several outbreaks of [[arthralgia]] and [[arthritis]] were described in the [[Northern Territory]], [[Queensland]] and the [[Schouten Islands]], off the northern coast of [[Papua New Guinea]]. The name "epidemic polyarthritis" was coined for the disease. In 1956, an epidemic occurred in the [[Murray River|Murray Valley]] which was compared to "acute viral polyarthritis" caused by [[Chikungunya virus|the Chikungunya virus]]. The Australian disease seemed to progress in a milder fashion. In 1956, [[serology|serological]] testing suggested an unknown new species of alphavirus (group A arbovirus) was the likely culprit.<ref name = Harley/>

In July and August 1956 and 1957, a virus recovered from [[mosquito]]es collected near [[Tokyo]], [[Japan]], and was dubbed '''''Sagiyama virus'''''.<ref>{{cite journal |vauthors=Scherer WF, Funkenbusch M, Buescher EL, Izumit |title=Sagiyama virus, a new group A arthropod-borne virus from Japan.

In 1959, a new alphavirus was identified in samples from a mosquito (''[[Aedes vigilax]]'') trapped in the [[Ross River (Queensland)|Ross River]], located in [[Townsville, Queensland|Townsville]], Queensland, Australia. Further serological testing showed that patients who had suffered "epidemic polyarthritis" in Queensland had antibodies to the virus. The new virus was named ''Ross River virus'', and the disease [[Ross River fever]].<ref name = Harley/>

The virus itself was first isolated in 1972 using suckling [[mouse|mice]]. It was found that RRV isolated from human serum could kill mice. However, the serum containing the virus that was used had come from an [[Aboriginal Australians|Aboriginal]] boy from [[Edward River]], North Queensland. The child had a fever and a rash but no arthritis, making the link between RRV and Ross River fever less than concrete.<ref name = Harley/>

The largest-ever outbreak of the virus was in 1979–1980 and occurred in the western Pacific. The outbreak involved the islands of [[Fiji]], [[Samoa]], the [[Cook Islands]], and [[New Caledonia]].<ref name=Barber09/> However, RRV was later isolated in humans following a series of epidemic polyarthritis outbreaks in [[Fiji]], [[Samoa]] and the [[Cook Islands]] during 1979. RRV was isolated in an Australian patient suffering from Ross River fever in 1985.<ref name = Harley/>

In 2010, ''Ross River virus'' was found to have made its way to the [[Aundh (Pune)|Aundh]] area in [[Pune]], [[India]], and spread to other parts of the city. The RRV infection is characterised by inflammation and pain to multiple joints. Hydration by sufficient fluid intake is recommended, to ensure that the fever does not rise to very dangerous levels. It is also recommended that a doctor be consulted immediately as regular paracetamol gives only temporary reprieve from the fever.{{citation needed|date=March 2013}}

==Ecology==
In rural and regional areas of Australia, the continued prevalence of ''Ross River virus'' is thought to be supported by [[natural reservoirs]] such as large [[marsupial]] mammals. [[Antibodies]] to ''Ross River virus'' have been found in a wide variety of [[Eutheria|placental]] and marsupial mammals, and also in a few bird species. It is not presently known what reservoir hosts support ''Ross River virus'' in [[metropolitan area|metropolitan]] areas such as [[Brisbane, Queensland|Brisbane]].<ref name=Harley/>

The southern saltmarsh mosquito (''[[Aedes camptorhynchus]]''), which is known to carry the ''Ross River virus'', was discovered in [[Napier, New Zealand]], in 1998. Due to an 11-year program by the [[Ministry of Health (New Zealand)|New Zealand Ministry of Health]], and later the [[Ministry of Agriculture and Forestry (New Zealand)|Ministry of Agriculture & Fisheries]], the species was declared completely eradicated from New Zealand in July 2010.<ref>{{cite web|url=http://beehive.govt.nz/release/new+zealand+first+wipe+out+%E2%80%98aussie+mozzie039|title=New Zealand first to wipe out the 'Aussie mozzie'|date=1 July 2010|publisher=New Zealand Government|access-date=24 January 2013|archive-date=19 November 2010|archive-url=https://web.archive.org/web/20101119160713/http://beehive.govt.nz/release/new+zealand+first+wipe+out+%e2%80%98aussie+mozzie039|url-status=live}}</ref> As of September 2006, there has never been a report of a case of ''Ross River virus'' acquired within New Zealand.<ref name=ARPHS>{{cite web|title=ARPHS Fact Sheet – Ross River Virus (RRV) Disease|url=http://www.arphs.govt.nz/Portals/0/Health%20Information/Communicable%20Disease/Disease%20Fact%20Sheets/Ross%20river%20virus/RossRiver.pdf|publisher=Auckland Regional Public Health Service|access-date=23 January 2013|archive-date=20 December 2012|archive-url=https://web.archive.org/web/20121220152806/http://www.arphs.govt.nz/Portals/0/Health%20Information/Communicable%20Disease/Disease%20Fact%20Sheets/Ross%20river%20virus/RossRiver.pdf|url-status=live}}</ref>

Separate mosquito species may act as vector, widespread across areas and seasonal/geographical locations. In southern and northern regions, the ''[[Aedes]]'' group (''A. camptorhynchus'' and ''A. vigilax'') are the main RRV carriers. However, inland the ''[[Culex annulirostris]]'' is the main carrier with ''Aedes'' mosquitoes becoming active during wet seasons.<ref>{{Cite journal|title = Ross River virus: ecology and distribution|last = Russell|first = R.C.|date = 31 January 2007|journal = Annu Rev Entomol|doi = 10.1146/annurev.ento.47.091201.145100|pmid = 11729067|volume=47|pages=1–31}}</ref>

A study comparing the risk of contracting ''Ross River virus'' (RRV) and the distance of the dwellings from Muddy Lakes.<ref name=":1">{{Cite journal|title = Ross River Virus Risk Associated with Dispersal of Aedes (Ochlerotatus) camptorhynchus (Thomson) from Breeding Habitat into Surrounding Residential Areas: Muddy Lakes, Western Australia|last = Jardine, A., Neville, P.

The study suggests that there is a significantly higher risk of contracting RRV when living closer to Muddy Lakes however, there was a rise in the two kilometre buffer zone of 3700 mosquitos with 94% ''Ae. camptorhynchus''.
A similar trend in the study same study conducted in the Peel region resulting in less mosquitoes the further away the buffer distance.<ref name=":0" />

In 1995–96 Leschenault and Capel-Busselton were affected by an outbreak of 524 cases of RRV disease.<ref name=":2">{{cite journal | last1 = Vally | first1 = H. | last2 = Peel | first2 = M. | last3 = Dowse | first3 = G.

This shows an elevated risk of contracting the disease if living in close proximity to the [[Leschenault Estuary]], within 2&nbsp;km being the strongest disease risk gradient.<ref name=":2" />

Evidence shows that there is a strong correlation between contracting RRV when living in close proximity to wetlands in the south west of Western Australia.<ref name=":0" /><ref name=":1" /><ref name=":2" /> However, due to continuous growth and development of residential areas around these wetlands it is expected that problems with RRV disease will occur.

== Risks ==
There are several factors that can contribute to an individual's risk for ''Ross River virus'' in Australia. These risks were trialed in a study conducted in tropical Australia<ref name=":3">{{Cite journal|title = Risks for Ross River virus disease in tropical Australia|last1 = Harley|first1 = David|date = 2005|journal = International Journal of Epidemiology|doi = 10.1093/ije/dyh411|pmid = 15659466|issue = 3|volume = 34|pages = 548–555|last2 = Ritchie|first2 = Scott|last3 = Bain|first3 = Chris|last4 = Sleigh|first4 = Adrian C|doi-access = free}}</ref> which illustrate that factors such as camping, light coloured clothing, exposure to certain flora and fauna and specific protective mechanisms are able to increase or decrease the likelihood of contracting the virus. By increasing the frequency of camping the individual's risk increases eight-fold, suggesting that an increased exposure to wildlife increases risk. This is shown by the narrow 95% confidence interval of 1.07–4.35 within the study. For example, an individual's exposure to [[kangaroo]]s, [[Wallaby|wallabies]] and [[Bromeliaceae|bromeliad plants]] also increased risk, suggesting that they are reservoirs for infection, breeding sites for mosquitoes and potential vectors of the virus. ''Ross River virus'' antibodies have been found in captive populations of [[Tammar wallaby|tammar wallabies]] and [[wallaroo]]s in urban areas in New South Wales, Australia, and are potential [[Natural reservoir|reservoirs]] for the virus.<ref>{{Cite journal |last1=Old |first1=Julie M |last2=Deane |first2=Elizabeth M |date=July 2005 |title=Antibodies to the Ross River Virus in Captive Marsupials in Urban Areas of Eastern New South Wales, Australia |url=http://dx.doi.org/10.7589/0090-3558-41.3.611 |journal=Journal of Wildlife Diseases |volume=41 |issue=3 |pages=611–614 |doi=10.7589/0090-3558-41.3.611 |pmid=16244073 |s2cid=43361929 |issn=0090-3558 |access-date=2 May 2023 |archive-date=2 July 2023 |archive-url=https://web.archive.org/web/20230702003526/https://meridian.allenpress.com/jwd/article/41/3/611/123094/Antibodies-to-the-Ross-River-Virus-in-Captive |url-status=live }}</ref> Although these areas show a higher risk for the virus, humans should still enjoy the wildlife but consider that preventive mechanisms as increasingly important while camping.

== Prevention ==
''Ross River virus'' can be easily prevented through small behavioural mechanisms which should be of high importance in tropical areas and during participation of outdoor activities.<ref name=Barber09>{{Cite journal|url = http://search.informit.com.au.ipacez.nd.edu.au/documentSummary;dn=251179120364691;res=IELHEA|title = Ross river virus|last1 = Barber|first1 = Bridget|date = 2009|journal = Australian Family Physician|last2 = Denholm|first2 = Justin T.|issue = 8|volume = 38|pages = 586–589|last3 = Spelman|first3 = Denis|pmid = 19893779}}{{Dead link|date=April 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Firstly, insect repellent should be rigorously used as to prevent bites from insects that specifically include mosquitoes which are vectors that carry the disease. A study in tropical Australia<ref name=":3" /> shows a very narrow 95% confidence interval of 0.20–1.00 for a decrease in ''Ross River virus'' risk as a result of increased use of insect repellent, suggesting a strong correlation between the two. Following, burning [[Citronella oil|citronella]] candles are based on the same principle, that it repels insects that are vectors of the virus. Burning such candles also show a strong correlation with decreased ''Ross River virus'' risk shown in the same study with a narrow 95% confidence interval of 0.10–0.78.  Secondly, wearing light coloured clothing decrease the risk of ''Ross River virus'' three-fold.<ref name=":3" /> This is again based on the repelling of vectors such as mosquitoes through the use of bright colours.  Lastly, high risk areas should be minimised by mechanisms of prevention that are applied within households.<ref name=Barber09 /> For example, screens should be fitted to windows and doors to prevent entry of insects carrying the virus and potential breeding areas such as open water containers or water holding plants should be removed. Therefore, specific climatic environments should be assessed for high risk factors and the appropriate precautions should be taken in response.

==Lab research==
The study of RRV has been recently facilitated by a mouse model. Inbred mice infected with RRV develop hind-limb arthritis/arthralgia. The disease in mice, similar to humans, is characterised by an inflammatory infiltrate including [[macrophage]]s which are immunopathogenic and exacerbate disease. Furthermore, recent data indicate that the serum component, C3, directly contributes to disease since mice deficient in the C3 protein do not suffer from severe disease following infection.<ref>{{cite journal |vauthors=Morrison TE, Fraser RJ, Smith PN, Mahalingam S, Heise MT |title=Complement contributes to inflammatory tissue destruction in a mouse model of Ross River virus-induced disease |journal=J.

== Symptoms ==
''Ross River virus'' can cause multiple symptoms in someone who is infected, the most common being [[arthritis]] or joint pain. Other symptoms include a [[rash]] on the limbs of the body, which often occurs roughly 10 days after arthritis begins. [[Lymph node]]s may enlarge, most commonly in the arm pits or groin region, and rarely a feeling of [[Paresthesia|'pins and needles']] in the persons hands and feet, but only occurs in a small number of people.<ref>{{Cite web|url = http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Ross_River_disease|title = Ross River Virus Disease|date = March 2013|access-date = 15 April 2015|website = Better Health Channel|publisher = Department of Health, State Government, Victoria|archive-date = 15 April 2015|archive-url = https://web.archive.org/web/20150415070750/http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Ross_River_disease|url-status = dead}}</ref>  The virus also causes moderate symptoms in [[horse]]s.<ref>{{cite journal |vauthors=Kumanomido T, Kamada M, Wada R, Kenemaru T, Sugiura T, Akiyama Y |title=Pathogenicity for horses of original Sagiyama virus, a member of the Getah virus group |journal=Vet Microbiol |volume=17 |issue=4 |pages=367–373 |date=1988 |doi=10.1016/0378-1135(88)90050-8 |pmid=2847399}}</ref>

The symptoms of ''Ross River virus'' are important to recognise for early diagnosis and therefore early treatment. Symptoms have been illustrated in a case report of an infected Thuringian traveller returning from South-East Australia.<ref>{{Cite journal|title = Ross river virus infection in a Thuringian traveller returning from south-east Australia|last1 = Schleenvoigt, B.T.|date = 2015|journal = Infection|doi = 10.1007/s15010-014-0695-0|pmid = 25380568|volume = 43|issue = 2|pages = 229–230|last2 = Baier, M.|last3 = Hagel, S.|last4 = Forstner, C.|last5 = Kotsche, R.|last6 = Pletz, M. W.| s2cid=33629748 }}</ref> This case showed flu-like symptoms that include [[fever]], [[chills]], [[headache]] and pains in the body. Additionally, [[Arthralgia|joint pain]] arose in which some joints become swollen and joint stiffness was particularly noticeable. A clinical examination of the infected individual shows a significant decrease of specific antibodies despite the normal blood count levels. A rash is a good indication that is likely to occur but usually disappears after ten days. The symptoms of ''Ross River virus'' are important to be aware of so that early treatment can be administered before the virus worsens. The time between catching the disease and experiencing symptoms is anywhere between three days to three weeks, usually it takes about 1–2 weeks. A person can be tested for ''Ross River virus'' by a [[blood test]], other illnesses may need to be excluded before diagnosis.<ref>{{Cite web|url = http://www.sahealth.sa.gov.au/|title = Ross River virus infection – Symptoms, Treatment and Prevention|website = SA Health|access-date = 16 April 2015|archive-date = 2 July 2023|archive-url = https://web.archive.org/web/20230702003539/https://www.sahealth.sa.gov.au/wps/wcm/connect/Public+Content/SA+Health+Internet/|url-status = live}}</ref>

== Diagnosis ==
Testing for ''Ross River virus'' should occur in patients who are experiencing acute polyarthritis, tiredness and/or rashes (~90%) with a history of travel within areas prone to infection from the virus.<ref>{{Cite journal|title = Epidemic polyarthritis and Ross River virus disease|last = Fraser|first = J.R.|date = 12 August 1986|journal = Clin Rheum Dis|pmid = 3026719|volume=12|issue = 2|pages=369–88|doi = 10.1016/s0307-742x(21)00556-7}}</ref> Serology (blood tests) is the appropriate manner by which to diagnose ''Ross River virus''. Within 7 days of infection, the virus produces [[Immunoglobulin M|Immunoglobulin M (IgM)]] and is a presumptive positive diagnosis. IgM may persist for months or even years and therefore false positives may be triggered by [[Barmah Forest virus]], [[rubella]], [[Q fever]] or [[rheumatoid factor]]. To completely test for ''Ross River virus'', a second serology test must be conducted 10–14 days after the first. The patient may then be declared positive for ''Ross River virus'' infection if there is a 4-fold increase of IgM antibody count.<ref name=Barber09/>

== Ross River fever ==
{{main|Ross River fever}}
Ross River fever is also known as ''Ross River virus infection'' or ''Ross River virus disease''. ''Ross River virus'' is named after the Ross River in Townsville, which is the place where it was first identified. Ross River fever is the most common mosquito-borne disease in Australia, and nearly 5000 people are reported to be infected with the virus each year.<ref>{{Cite web|url = http://www.kimberleyaustralia.com/|title = Ross River Virus – Ross River Fever|website = Kimberley Australia|access-date = 16 April 2015|archive-date = 15 May 2023|archive-url = https://web.archive.org/web/20230515153632/https://www.kimberleyaustralia.com/|url-status = live}}</ref>
