Oropouche Fever -An Emerging Public Health Concern in Tropical Regions

Abstract

Oropouche fever is an emerging infectious disease caused by the Oropouche virus and has become an increasing concern for public health. The virus is spreading more widely across regions, influenced by environmental, social, and ecological factors such as climate change, urbanization, and vector distribution. Its symptoms-fever, headache, muscle pain, and fatigue-closely resemble those of other Arboviruses, making accurate diagnosis essential for effective management and prevention. The disease is transmitted mainly through insect vectors, particularly biting midges and mosquitoes, which play a key role in viral proliferation. Once inside the human body, the virus invades host cells and triggers immune responses that contribute to symptom development. In some cases, severe complications may arise, including neurological effects, death, and risks to unborn babies, highlighting the need for timely detection. Diagnosing Oropouche fever remains challenging due to symptom overlap with other infections. Current Diagnostic methods, including serological and molecular techniques, have limitations in accuracy, availability, and accessibility, especially in low-resource settings. As a result, misdiagnosis is common. There are no specific antiviral drugs or approved vaccines available, so Supportive care remains the primary approach to patient management. Strengthening Disease surveillance, improving diagnostic tools, and developing vaccines are crucial steps in controlling the spread of OROV and reducing its impact on affected populations.
