The Oropouche fever is a tropical infectious disease caused by the Oropouche virus. It occurs in the Amazon , the Caribbean, and Panama . The name is derived from the Oropuche River on the island of Trinidad .
The pathogen is the Oropouche virus and belongs to the Bunyaviridae family . It is caused by mosquitoes or through the midge Culicoides paraensis the people transferred and therefore the non-taxonomic group of arboviruses expected. Wild mammals ( sloths ), birds and, after the virus has adapted, recently also humans serve as virus reservoirs .
The first outbreak occurred in the 1950s. The disease is now one of the most common infectious diseases in Brazil , with hundreds of thousands of people suffering from it. The intensification of cocoa cultivation in Brazil (mosquito brood in empty, water-filled cocoa shells) has led to an increase in mosquitoes in recent years and thus to an increased, epidemic-like increase in transmissions and diseases to humans.
