Yellow fever is a viral hemorrhagic fever that is transmitted by mosquitoes. It was one of the most feared epidemic diseases in the world with the capacity to bring devastation to almost every continent. Mass vaccination campaigns in the mid-20th century succeeded in bringing the disease under control for over 40 years. However, since the late 1980s, this deadly disease has returned, putting a new generation at risk in West and Central Africa and threatening to erupt into devastating urban epidemics 1.
