Understanding Oropouche fever: symptoms of this mosquito-borne illness | Health

Oropouche fever, a mosquito-borne disease caused by the Oropouche virus, has recently made headlines with the first-ever case reported in Italy on June 15. This marks the first case to be detected in continental Europe, while Latin America and the Caribbean have already experienced outbreaks this year.

The patient diagnosed in Italy had recently returned from a trip to the Caribbean, highlighting the potential for international spread of the disease. Oropouche virus disease is primarily transmitted through the bites of infected midges and mosquitoes, putting travelers at risk in affected regions.

Countries like Brazil have seen a significant increase in diagnosed cases of Oropouche fever this year, with over 5,500 cases reported compared to about 840 cases in 2023. This rise in cases has also been observed in countries that have never previously detected the disease, such as Cuba, where the WHO reported the first-ever outbreak with 70 confirmed cases.

Symptoms of Oropouche fever are similar to dengue and typically include fever, headaches, joint pain, chills, and occasionally nausea and vomiting. The disease usually lasts about seven days, with severe cases being rare. Despite the similarities to dengue, there is currently no specific vaccine or antiviral treatment available for Oropouche fever.

The spread of Oropouche fever is influenced by various factors, including climate conditions and environmental changes. While tropical climates are typically associated with transmission events, some outbreaks have occurred outside of these conditions. Additionally, vegetation loss and deforestation appear to be linked to outbreaks of the disease, highlighting the impact of human activities on the spread of Oropouche fever.

As the global health community continues to monitor and respond to the spread of Oropouche fever, it is important for individuals to take precautions when traveling to affected regions and be aware of the symptoms of the disease. Stay informed and follow guidelines from health authorities to prevent the spread of Oropouche fever and other mosquito-borne illnesses.
