Member of the Moroccan Scientific Committee for Vaccine Said Moutaouakkil sounded caution around the spread of the mosquito-borne virus dengue fever as cases increase worldwide.
Morocco, “like every other country, is not exempt from the risk of dengue fever cases” he told Hespress EN.
Dengue fever, also known as breakbone fever, is a viral infection transmitted through the bite of infected Aedes mosquitoes. These mosquitoes are most active during the day and thrive in warm, humid environments.
Moutaouakkil said, “The virus causes a range of symptoms, including high fever, severe joint and muscle pain, headaches, nausea, vomiting, and a rash.”
While most cases of dengue fever are mild and resolve within a week or two, more severe cases can lead to complications such as internal bleeding, shock, and in some rare instances, even death.
The recent spread of dengue fever around the globe has raised concerns among health experts and policymakers.
According to the World Health Organization (WHO), dengue fever is now endemic in over 80 countries, with an estimated 390 million infections occurring annually. In 2024, over 10 million infections were reported worldwide.
The disease is currently prevalent in Southeast Asia, the Western Pacific, and Latin America, but cases are also increasing in Africa and the Mediterranean region.
With its warm climate and coastal areas, Morocco is not immune to dengue fever threat. In 2002, the Aedes aegypti mosquito, a primary vector for dengue fever, was isolated in Marrakech and another in Rabat in 2015.
The increasing risk of dengue fever in Morocco is compounded by the effects of climate change. Rising temperatures and altered rainfall patterns are creating more favorable conditions for the Aedes mosquitoes, expanding their range and extending the transmission season.
This, in turn, increases the likelihood of human contact with the infected mosquito and the spread of dengue fever.
Beyond these efforts, individual preventative measures are also crucial: Prof. Said emphasizes “the use of anti-mosquito measures” mosquito nets, applying insect repellents with DEET or other approved ingredients, and wearing long sleeves and pants when in areas with high mosquito activity. Additionally, individuals should seek medical attention promptly if they experience any symptoms of dengue fever, such as high fever, severe joint pain, or a rash.
Vaccines against dengue fever exist; however, as Prof. Moutaouakkil noted, “the vaccine is currently only available in some countries and is not accessible to everyone.”
Dengue fever can be a hidden threat to Morocco, particularly in the context of climate change. Therefore, by implementing effective prevention and control strategies, raising public awareness, and supporting research efforts, Morocco can mitigate the risk of dengue fever outbreaks and protect its citizens from this potentially debilitating disease.
