The rising concern of Oropouche fever: a call for enhanced surveillance and research in emerging arboviral threats.

ABSTRACT

AIM OF STUDY The study aims to assess the growing public health threat posed by Oropouche virus (OROV), focusing on its epidemiology, transmission patterns, and the challenges in diagnosis and control. By analyzing the recent spread of OROV to new regions, including Cuba and Colombia, the study seeks to highlight the need for improved surveillance, enhanced diagnostic capabilities, and research into potential treatments and vaccines. Additionally, the study investigates the clinical similarities between Oropouche fever and other arboviruses, which often lead to diagnostic difficulties and mismanagement in affected regions. RESULTS: The virus has caused over 500,000 cases in Brazil alone, with recent outbreaks reporting fatalities, suspected vertical transmission, and potential associations with microcephaly in newborns. Underreporting and limited surveillance have likely led to the underestimation of the true burden of Oropouche fever. Current diagnostic methods, such as serology and RT-PCR, are often inaccessible in low-resource settings, further complicating efforts to control the spread of the virus. The study highlights the importance of improving diagnostic capacity, enhancing surveillance, and conducting further research into vector control, antiviral treatments, and vaccine development. CONCLUSION: This study emphasizes the urgent need for coordinated international efforts to address the rising threat of Oropouche virus. Considering its rapid spread and potential for global transmission, comprehensive public health measures are necessary to protect vulnerable populations and mitigate the impact of this emerging disease. Enhanced surveillance and the development of accessible diagnostics, vaccines, and treatment options are critical to containing OROV and preventing further outbreaks.
