Since late 2023, several outbreaks of Oropouche fever have been occurring in the Americas. In Brazil alone, more than 17.400 cases were recorded between 2023 and 2025, according to data Ministry of Health.
Fulfilling the mission of providing responses to public health, professionals from the Oswaldo Cruz Institute (IOC/Fiocruz) have been contributing with a series of initiatives. The most recent is the production of an operational manual to guide teams of entomologists from the Americas in identifying the main taxonomic and ecological characteristics of the species of the insect vector of the disease.
The document prioritized species of greatest interest to public health and whose identification uses techniques and equipment easily found in laboratories. Click on the image to access
Named “Operational document for the identification of Culicoides Latreille (Diptera: Ceratopogonidae)”, the guide was prepared by Maria Luiza Felippe Bauer and Maria Clara Alves Santarém, curators of the Ceratopogonidae Collection of IOC, linked to the Diptera Laboratory. The product was produced in partnership with the Pan American Health Organization (PAHO).
The document highlights the diagnostic characteristics of the main species that are frequently and abundantly found in entomological surveys in Central and South America, as well as their distribution and bionomy. An illustrated key for identifying the species of the paraensis group is also provided.
Caused by virus Orthobunyavirus oropoucheense, Oropouche fever is transmitted mainly by Culicoides paraensis, popularly called maruim or sandfly.
In addition to Brazil, cases of the disease are distributed across Bolivia, Colombia, Cuba, Guyana, Peru and the Dominican Republic.
Spider gnats are very small insects, which makes them difficult to capture and identify: they measure between 1,5 mm and 3 mm. Their sting is known to be very painful. click here for more details about the insect and here to check out special of news about oropouche.
Recently, experts have drawn up a Technical note with guidelines to improve surveillance of Oropouche fever vectors in the state of Rio de Janeiro.
Watch the recent session of the Center for Studies of IOC on 'Contributions from clinical, entomological and virological aspects to the national emergency of the Oropouche virus'.
