This summer, several cities carried out operations to mosquito control. The latest were held in Colombes (Hauts-de-Seine) and in the 13th arrondissement of Paris, at the end of August, following the detection of dengue fever cases. These operations are triggered in specific cases.
“When a case of dengue fever, chikungunya or zika is identified by a health professional, he reports it to the Regional Health Agency”explains theARS. An epidemiological survey is then carried out with each patient concerned in order to identify the places frequented during their period of viremia (contagious period when the person can transmit the virus to a mosquito during a bite).
How does a mosquito control operation take place?
Then, research is carried out in the immediate vicinity of the people concerned and the places they frequent, continues the ARS. “The objective is to identify the possible presence of tiger mosquitoes and to take the appropriate control measures”. The objective is “to prevent tiger mosquitoes present from biting the sick person and transmitting the disease to other people around”.
The treatments are aimed at adult tiger mosquitoes. Indeed, “the eggs, larvae and nymphs of this mosquito are not contaminating”, specifies the ARS. Treatments are initiated by the health authorities in the event of a risk of epidemic spread of the virus. dengue, chikungunya or zika. They are sprayed at night within a perimeter of 150 m around places frequented by patients.

What is dengue fever?
The dengue is an infectious disease that is transmitted from person to person through the bite of an infected tiger mosquito. The virus circulates regularly in the French departments of the Antilles, as well as in the French islands of the Pacific and the Indian Ocean.
Symptoms are most often flu-like (fever, headache, body aches) and appear within 3 to 14 days following the mosquito bite. Often mild, dengue fever can present complications. Hemorrhages then appear on the skin, mucous membranes and digestive walls.
If you have symptoms, it is necessary to consult your doctor, reminds the Ministry of Health.
What are the right steps to take?
L’Considered recalls the habits to adopt to destroy the breeding grounds of tiger mosquitoes and thus curb their proliferation. Think of :
– regularly empty or remove the cups under the flower pots, vases… or fill them with sand in order to retain the humidity without there being stagnant water
– store, sheltered from the rain, buckets, gardening equipment, toys or miscellaneous containers
– cover the water collection containers with a mosquito net or fabric
– clear the gutters to facilitate the proper flow of water.
On the clothing side, opt for long, loose and light clothes. You can also use cutaneous repellents by following the precautions for use indicated as well as mosquito nets.
