Guyana has confirmed its first case of Oropouche fever, part of a broader outbreak in the Americas that has seen over 12,000 infections reported by the Pan American Health Organization (PAHO). Health authorities are increasing surveillance and urging citizens to take preventive measures.
As of July 27, 2025, PAHO documented 12,786 cases across 11 countries, with local transmission reported in seven nations. In the Caribbean, Cuba has recorded 28 cases, while Guyana’s first infection marks the virus’s entry into the country.
Oropouche fever is transmitted by the Culicoides paraensis midge, thriving in urban areas affected by climate change and deforestation. Brazil is the outbreak’s epicenter, with 11,888 cases and five reported deaths.
Symptoms include high fever, intense headaches, muscle and joint pain, and fatigue, typically appearing four to eight days post-infection. While most recover within two to three weeks, relapses can occur, and severe complications, although rare, may arise.
Currently, there is no vaccine or specific antiviral treatment. Health officials emphasize the importance of early diagnosis to differentiate it from similar diseases like dengue. The Ministry of Health in Guyana is intensifying monitoring, particularly in high-risk areas, and promoting public education on prevention and symptom recognition.
