The recommendations of a virologist
For his part, the expert in virology Mahjoub Ouni recommended, Wednesday September 3, 2025, to take all the measures necessary to eliminate the mosquito transmitting the virus of Western Nile fever.
Mahjoub Ouni, the prevention indicates that prevention comes above all through the protection of dwellings with mosquito nets, the use of repellents and insecticides, as well as the elimination of stagnant waters, real foci of mosquitoes proliferation.
Transmission and symptoms
The virus mainly affects birds. Some mosquitoes become bearers after stinging an infected bird and can then transmit the virus to humans. Ouni insisted:
“The virus is never transmitted from one human being to another”.
He added that 80% of infected people have no symptoms. The remaining cases can suffer from fever, headache, muscle pain, fatigue, digestive disorders or rashes. In the elderly or fragile, infection can evolve towards serious neurological complications, requiring hospitalization.
No specific vaccine or treatment currently exists against Western Nile fever. Monitoring is provided in Tunisia by several research centers, including the Pasteur Institute, which monitors the evolution of the situation.
