The Cuiaba Health Surveillance Directorate, through the Strategic Health Surveillance Information Center (CIEVS), has issued a community alert about the increasing risk of Oropouche Fever (FO). This measure aims to strengthen surveillance and early detection of suspected cases in Cuiaba, and comes in response to various outbreaks recorded in several regions, including Brazil, Ecuador, French Guiana, Panama, Peru, and Trinidad and Tobago throughout 2024.
Outbreaks have affected people of all ages and genders, with children and young people being most affected, particularly in populations previously exposed to the disease. In Brazil, as of February 24, 2024, 2,104 positive samples for the virus were detected, the majority of which were concentrated in the northern region, especially in the Amazon region. However, isolated cases in other regions, such as one confirmed case in Rio de Janeiro with a history of travel to Amazonas and nine confirmed cases in Pará, highlight the importance of surveillance and early detection of the disease. To date, there are no confirmed cases of the disease in Cuiabá and the country.
Oropouche fever is a disease caused by oropouche virus, transmitted by the bite of vector mosquitoes of the genus Culicoides paraensis and Culicoides insignis, commonly known as “maruim” or “porvinha”. Symptoms include sudden fever, headache, muscle pain, joint pain, dizziness, sensitivity to light, nausea, vomiting, and, in more serious cases, central nervous system complications and hemorrhagic manifestations. It is important to consider Oropouche fever in patients with these symptoms, especially when tests for dengue, chikungunya, and Zika show negative results.
Prevention and control measures aim to reduce the spread of vector mosquitoes, including eliminating places where they breed and rest, such as wet areas rich in organic matter. Urban cleaning, sanitation and use of repellents are essential to control the vector.
Any suspected case of the disease must be reported to the Cuiaba Epidemiological Surveillance Center within 24 hours, via WhatsApp (65) 99206-8618. For travelers who exhibit symptoms, it is important to seek medical assistance, and report your travel route, especially if it includes areas affected by Oropouche fever.
