Transmission of the dengue virus was identified in the Hérault department, in the town of Cessenon-sur-Orb, northwest of Béziers.
This indigenous case has been taken care of and his state of health does not cause concern. This person was infected in mid-July, while he was staying near a swimming area and nautical activities between the municipalities of Cessenon-sur-Orb and Murviel-lès-Béziers, at a place called La base by Réals.
The imported case causing the contamination (returning from a trip to a risk area) was identified nearby.
Dengue is a generally mild disease whose symptoms, similar to those of the flu (high fever, joint pain, severe headaches), can be temporarily disabling. This disease is transmitted from person to person through the bite of a tiger mosquito (Aedes albopictus) previously infected with the virus.
Since the start of the seasonal surveillance period on May 1 and with the exception of this event, all cases reported nationally are “imported” cases, linked to travelers returning to France. A case is said to be “indigenous” when a person contracts the disease without having traveled to a contaminated area in the 15 days preceding the onset of symptoms.
In view of this “indigenous” case identified in the Hérault department, reinforced prevention measures are implemented near the case and the area concerned.
Reinforced prevention measures
To avoid a possible spread of the virus, reinforced preventive and health surveillance measures are being implemented. They mobilize the services of the State, the Regional Health Agency -ARS- of Occitanie, Public Health France, as well as health professionals in the sector and the mosquito control operator.
A local epidemiological survey will be carried out in the coming days with the neighborhood, in order to identify possible other sick people. Health professionals in the sector are also made aware of the identification of sick people and their reporting to the ARS.
