Authorities say dengue fever is on the rise in Mali, posing a new threat to the West African nation struggling with extremist attacks and political turbulence.
A senior Malian health and public hygiene official confirmed 21 deaths and 600 cases of the disease as of Monday.
Dengue is a viral infection spread by mosquitoes that mostly causes flu-like illness. In severe cases, it can cause joint pain, swollen glands, bleeding and death. There is no specific treatment, but two vaccines have been recommended by the World Health Organization for countries that suffer regular outbreaks.
