Ndumu virus is an RNA virus in the genus Alphavirus . [1] It was first isolated in 1961 from culicine mosquitoes collected in northern Natal, Union of South Africa. [2]
Ross River virus (RRV) is a small encapsulated single-strand RNA Alphavirus 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, and has been found on occasion in horses.
The o'nyong'nyong virus (ONNV) was first isolated by researchers at the Uganda Virus Research Institute in Entebbe, Uganda, during a large outbreak of a disease in 1959 that resembled dengue fever. ONNV is a togavirus, genus Alphavirus, is closely related to the chikungunya and Igbo Ora viruses, and is a member of the Semliki Forest antigenic complex. The name was given to the disease by the Acholi tribe during the 1959 outbreak. The name comes from the Nilotic language of Uganda and Sudan and means "weakening of the joints". The virus can infect humans and may cause disease.
Alphavirus is a genus of RNA viruses, the sole genus in the Togaviridae family. Alphaviruses belong to group IV of the Baltimore classification of viruses, with a positive-sense, single-stranded RNA genome. There are 32 alphaviruses, which infect various vertebrates such as humans, rodents, fish, birds, and larger mammals such as horses, as well as invertebrates. Alphaviruses that could infect both vertebrates and arthropods are referred dual-host alphaviruses, while insect-specific alphaviruses such as Eilat virus and Yada yada virus are restricted to their competent arthropod vector. Transmission between species and individuals occurs mainly via mosquitoes, making the alphaviruses a member of the collection of arboviruses – or arthropod-borne viruses. Alphavirus particles are enveloped, have a 70 nm diameter, tend to be spherical, and have a 40 nm isometric nucleocapsid.
Oropouche orthobunyavirus (OROV) is one of the most common orthobunyaviruses. When OROV infects humans, it causes a rapid fever illness called Oropouche fever. OROV was originally reported in Trinidad and Tobago in 1955 from the blood sample of a fever patient and from a pool of Coquillettidia venezuelensis mosquitoes. In 1960, OROV was isolated from a sloth and a pool of Ochlerotatus serratus mosquitoes in Brazil. The virus is considered a public health threat in tropical and subtropical areas of Central and South America, with over half a million infected people as of 2005. OROV is considered to be an arbovirus due to the method of transmission by the mosquitoes Aedes serratus and Culex quinquefasciatus among sloths, marsupials, primates, and birds.
Culex or typical mosquitoes are a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles.
Sindbis virus (SINV) is a member of the Togaviridae family, in the Alphavirus genus. The virus was first isolated in 1952 in Cairo, Egypt. The virus is transmitted by mosquitoes. SINV is linked to Pogosta disease (Finland), Ockelbo disease (Sweden) and Karelian fever (Russia). In humans, the symptoms include arthralgia, rash and malaise. Sindbis virus is widely and continuously found in insects and vertebrates in Eurasia, Africa, and Oceania. Clinical infection and disease in humans however has almost only been reported from Northern Europe, where SINV is endemic and where large outbreaks occur intermittently. Cases are occasionally reported in Australia, China, and South Africa.

Kunjin virus (KUNV) is a zoonotic virus of the family Flaviviridae and the genus Flavivirus. It is a subtype of West Nile virus endemic to Oceania.
Aedes pembaensis is a mosquito.
Jamestown Canyon encephalitis is an infectious disease caused by the Jamestown Canyon virus, an orthobunyavirus of the California serogroup. It is mainly spread during the summer by different mosquito species in the United States and Canada.
The Peruvian horse sickness virus (PHSV) is a cause of the neurological disorder Peruvian horse sickness resulting in encephalitis in horses and other livestock. The disease has significantly affected livestock in areas of Peru and has also been documented in northern Australia.
Lubombo virus (LUBV) is an orbivirus that infects vertebrates and culicine mosquitoes, thought to be its arthropod vector. It is classified in the genus Orbivirus and the family Reoviridae. It is studied at biosafety level 2.
Spondweni virus is an arbovirus, or arthropod-borne virus, which is a member of the family Flaviviridae and the genus Flavivirus. It is part of the Spondweni serogroup which consists of the Sponweni virus and the Zika virus (ZIKV). The Spondweni virus was first isolated in Nigeria in 1952, and ever since, SPONV transmission and activity have been reported throughout Africa. Its primary vector of transmission is the sylvatic mosquito Aedes circumluteolus, though it has been isolated from several different types of mosquito. Transmission of the virus into humans can lead to a viral infection known as Spondweni fever, with symptoms ranging from headache and nausea to myalgia and arthralgia. However, as SPONV is phylogenetically close to the ZIKV, it is commonly misdiagnosed as ZIKV along with other viral illnesses.
Aedes cordellieri is a sub-Saharan African species of mosquito suspected of being a vector of yellow fever. The species name honors Dr. Roger Cordellier, a former medical entomologist with Office de la Recherche Scientifique et Technique Outre-Mer (ORSTOM) in Ivory Coast, in recognition of his contributions to the knowledge of the mosquito fauna of Africa.
Culex perfuscus is the only Culex species mosquito currently implicated as a possible vector of Zika virus. The species type was described in 1914 from Port Herald, Nyasaland by entomologist Frederick Wallace Edwards.
The Afrotropical mosquito genus Eretmapodites contains species that exhibit facultative cannibalism in their larval developmental stages. The species was first described in 1901 by Frederick Vincent Theobald. The type species is Eretmapodites quinquevittatus Theobald
Palm Creek virus (PCV) is an insect virus belonging to the genus Flavivirus, of the family Flaviviridae. It was discovered in 2013 from the mosquito Coquillettidia xanthogaster. The female mosquitoes were originally collected in 2010 from Darwin, Katherine, Alice Springs, Alyangula, Groote Eylandt, Jabiru and the McArthur River Mine, and had since been preserved. The discovery was made by biologists at the University of Queensland. The virus is named after Palm Creek, near Darwin, from where it was originally isolated.
Middelburg virus (MIDV) is an alphavirus of the Old World Group that has likely endemic and zoonotic potential. It is of the viral family Togaviridae. It was isolated from mosquitos in 1957 in South Africa, MDIV antigens have now been found in livestock, horses, and humans.
Kedougou virus (KEDV) is an arbovirus of the Flaviviridae family, genus Flavivirus, belongs to the IV group of a viruses. The virus was first isolated from Aedes minutus mosquitoes in Senegal in 1971. KEDV belongs to the Kedougou virus group. It is endemically present in the Kédougou Region, from which it takes its name, together with other arboviruses of the genus Flavivirus such as: Yellow fever virus (YFV), West Nile virus (WNV) and Zika virus (ZIKV). KEDV has also been isolated from Aedes circumluteolus mosquitoes collected in Ndumu, KwaZulu-Natal, South Africa.
Ngari virus (NRIV) is a single-stranded, negative sense, tri-segmented RNA virus. It is a subtype of the Bunyamwera virus (BUNV) and closely related to the Batai virus (BATV). NRIV is the only reassortment virus of the subtypes. There is evidence suggesting that NRIV stems from a naturally occurring reassortment event in which a host was infected with both BUNV and BATV. It is commonly found in areas that experience an outbreak of Rift Valley fever virus (RVFV)
