The Oropouche virus (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 (''Bradypus tridactylus'') and a pool of Ochlerotatus (''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 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. ==Epidemic Sites== Between 1961 to 1980, OROV was reported in the northern state of Pará, Brazil, and from 1980 to 2004, OROV had spread to the Amazonas, Amapá, Acre, Rondônia, Tocantis, and Maranhão.〔 The virus would cause Oropouche fever, an urban arboviral disease that has since resulted in >30 epidemics during 1960-2009.〔
