Yellow Fever: A Reemerging Threat in the Modern World
Yellow fever, a viral hemorrhagic disease transmitted by infected mosquitoes, has been a significant public health concern for centuries. Despite the availability of an effective vaccine, the disease continues to pose a substantial threat, particularly in tropical regions of Africa and South America. Recent outbreaks highlight the persistent challenges in combating yellow fever and underscore the need for sustained global health efforts.
Historical Context and Epidemiology
Yellow fever has a long history, with documented outbreaks dating back to the 17th century. The virus is primarily transmitted by Aedes aegypti mosquitoes, which thrive in urban environments. Historically, yellow fever outbreaks have caused significant mortality and morbidity, leading to economic disruptions and public health crises (Centers for Disease Control and Prevention [CDC], 2024).
In recent years, there have been notable outbreaks in Angola, the Democratic Republic of the Congo, and Brazil. These outbreaks have underscored the ongoing vulnerability of populations in endemic regions and the potential for urban centers to become epicenters of transmission. The World Health Organization (WHO) estimates that yellow fever causes 30,000 to 60,000 deaths…
