Brazil is facing the largest outbreak of Oropouchi fever in history. As of the end of July, 7,500 cases had been confirmed in 21 states in the country, and there are suspicions of underreporting due to limited testing opportunities.
In addition, the disease, previously endemic in the Amazon region, has spread across the country, and doctors have documented new complications as cases rise: For the first time in history, Oropouche-related deaths have been confirmed, and eight cases of maternal Infant infection cases.

Symptoms of Orop’s disease include fever, malaise, fatigue, muscle pain and intestinal discomfort, a condition that is very similar to dengue fever. In rare cases, patients may develop meningitis and hemorrhagic fever.
This viral disease has an vector that has attracted little attention until this year, namely Culicoidesmaruim or sandflies, disease-carrying insects.
What do Oropuche mosquitoes look like?
Marums have round white spots on their wings (hence the name gunpowder) and live especially in areas with many fruit trees.
“Despite being called a sandfly, it is But actually sandflies are not mosquitoes, but insects.
Although it seems to be just a naming issue, it has a direct impact on disease control. one Technical description Guidance for health teams issued by the International Olympic Committee in August suggested that traditional methods of controlling the disease through insect bites may not be effective for Malum.
How to avoid Marum?
maruim are very small, about 1.5 mm, smaller than other disease-transmitting insects known to us, e.g. Aedes aegyptireaching 7 mm when filled with blood. Common mosquitoes are between 3 and 4 mm in size. Therefore, netting and mosquito nets may not be effective against sandflies – they are too small and can move through the plot.
“The most recommended fabrics are those made of a very fine mesh, such as voile (similar to tulle)”, researcher Maria Clara Alves Santarón, one of the curators of the technical note said Maria Clara Alves Santarém and Maria Luiza Felippe Bauer. In an interview with Fiocruz, they discussed the main characteristics of this insect.
Additionally, since maruim are not mosquitoes, they are immune to repellents and most insecticides. Therefore, for personal protection, experts recommend wearing long clothing, especially in the late afternoon. Another effective method is to apply body oil to your skin, as insects will eventually stick to the oil and be unable to fly due to their small size.
Another important difference with maruim is that it reproduces by decomposing organic matter rather than in water. This insect does not preferentially feed on blood and only does so during reproduction. Their bites are more painful than those of other insects and are usually felt.
Maruim is the main spreader of Oropuche fever Pernilingo may also be a threat
In addition to maruim, mosquitoes or muriçoca may also be secondary vectors of oropouche, especially in urban environments. Maruim can be infected with a low viral load, meaning they don’t need much contact with the virus, whereas mosquitoes require a high viral load. However, recent research has yet to show whether mosquitoes play a role in the current disease outbreak.
