“Most reported cases involve adult men,” explains Dr. Kalif Keita, Deputy Director General of Public Health and Hygiene. The Ministry of Health has identified 12 confirmed cases so far in Bamako, Koulikoro, and Kalaban Coro districts, signaling an emerging public health crisis.

Dengue in Mali: a recurring threat

This isn’t Mali’s first encounter with dengue. The virus was first detected in 2008, with subsequent outbreaks in 2017 and 2019. Following Burkina Faso’s declaration of cases early this year, Malian authorities intensified surveillance. However, limited diagnostic resources and overlapping symptoms with malaria complicate tracking and reporting across West Africa.

Why is dengue underreported?

• Diagnostic challenges: Many healthcare facilities lack the tools to distinguish dengue from malaria.
• Symptom mimicry: Fever, headaches, and muscle pain often lead to misdiagnosis.
• Data gaps: Insufficient epidemiological studies obscure the true scale of outbreaks.

Health experts emphasize the need for enhanced surveillance and public awareness to curb transmission, especially as rainy seasons approach.

Prevention: the best defense

The World Health Organization (WHO) recommends proactive measures to combat mosquito populations:

• Eliminate stagnant water sources (breeding grounds for mosquitoes).
• Use insect repellents and wear protective clothing.
• Install window screens and sleep under mosquito nets.

Travelers to Mali and returning residents are urged to monitor symptoms for 14 days and seek immediate medical care if fever or severe pain occurs.

Key takeaways

• Mali confirms 12 dengue cases in Bamako and surrounding areas.
• Dengue resurfaces periodically, with prior outbreaks in 2008, 2017, and 2019.
• Underreporting stems from diagnostic limitations and symptom overlap with malaria.
• Preventive measures are critical to curb transmission during peak mosquito seasons.
