Update on the early return of the tiger mosquito in the south of France, especially in Gironde, due to the rainy weather conditions of this winter and warm spring. Several departments have been placed on red alert because of tropical diseases such as dengue or Chikungunya, of which it is the vector. Commentary on factual images, illustration images, and explanations on infographics alternating with the interview of Jérôme SALOMON, Director General of Health, on the precautions to be taken.
The Health Directorate called for enhanced surveillance in the Var, as the presence of the mosquito potentially carrying the virus has been established there. The virus itself has not been detected but prevention and information actions have begun. Interview with Charles JEANNIN, entomologist: he explains how the mosquito arrived in the Var. Interview of residents of Ste-Maxime, who do prevention.
Report. A mosquito has been the vector of tropical diseases in Europe for several years. The aedes albopictus has for several years colonized the coast of the Maritime Alps, as it has in 25 years colonized huge areas in the world benefiting from global warming. It spreads through human means of transport (train, car...). In Paris a laboratory of the Institut Pasteur is studying the mosquito capable of spreading dengue and chikungunya, diseases against which there is no drug. A vaccine against chikungunya is currently being developed. Comments on factual images, illustrations and maps alternating with the interview of Charles JANIN, entomologist, Anna-Bella FAILLOUX, entomologist at the Institut Pasteur, Antoine FLAHAULT, of the French cell of research on chikungunya, Odile LAUNAY, researcher at the Cochin Pasteur Hospital.
Report in Fréjus where the disease, Chikungunya, has just been diagnosed in a resident of a neighborhood of the city. He is the first native of the disease and the child is currently being treated at home. The virus is transmitted by tiger mosquitoes, which have colonized a part of the world in 25 years. However, there is little risk of spreading the disease if a demoustication campaign is organized. Commentary on factual images interspersed by the interview of Dr.Philippe DESPRES (from the Institut Pasteur) and Jean-Jacques COIPLET (Director of Public Health at the regional health agency Provence Alpes Côte d'Azur).
Report. Announcement of the alert from the health authorities of the French Riviera, following the report of a case of West Nile virus infection in Nice. This disease had not been found on a human in France since 1963. Alternating commentary on factual images, illustration images, geographical maps (with luminous or colour animations of cases found in the world and the spread of the disease in the United States in 1999) and the interview with the professor of the CHU de Nice, Pierre DELLAMONICA. [Source: France 2 prompter] That brings us to health. The authorities are on alert on the French Riviera. A case of West Nile virus infection has been reported for the first time in France since 1963. Jean-Daniel FLAYSAKIER, Olivier THERON
Report filmed in the Nice region, where the "tiger mosquito", vector of the Chikungunya virus in La Réunion, was detected by scientists, but without being carrier of the disease. Commentary on images of a Nice district and amusing reactions of pétanque players, photo of the mosquito on a computer screen and illustration images alternating with interviews with Didier FONTENILLE, researcher at the IRD (Institut de Recherche pour le Développement), and Pascal DELAUNAY, medical entomologist (CHU de Nice).
Global warming will have a lasting impact on the health of people living in countries bordering the Mediterranean. This is particularly the case with the development of insects carrying diseases such as dengue fever or Chikungunya
A year after the outbreak of a chikungunya epidemic in Réunion, we know a little more about this famous mosquito virus. Despite the demoustication operations, it is still present on the island and extends into the Indian Ocean. According to some experts, it could even one day win European capitals. The struggle is ongoing. Sometimes you have to kill mosquito larvae, sometimes you have to kill adult mosquitoes. The other fight is in the labs. Interviews with Julien THIRIA, Head of Mosquito Control at Reunion Island, Professor André FLAHAULT, Director of the Chikungunya Research Cell and the Minister of Health, Xavier BERTRAND on the first successes of treatment with nivaquine.
Report to La Réunion on the fight against the epidemic of Chikungunya, a virus known in Africa and Asia that is transmitted by mosquitoes and which has recently spread to the island. Interviews with Alain MONTMAYEUR, dental technician, about the symptoms of this virus and Nathalie LEKEUX, pharmacist, who testifies to the spread of the disease.
Can the tiger mosquito transmit diseases? This is an aboriginal case that was identified in Biscarosse. In this case, mosquitoes must be eradicated in a vector radius, 150 metres around the victim. Interview with Fabienne JOUANTHOUA, head of the ARS health division in Gironde.
The chikungunya virus that struck Reunion Island in 2005, did not remain confined to tropical regions. The mosquito that transmits this virus has also adapted to the Mediterranean climate. It already proliferates in Languedoc-Roussillon, and particularly in Hérault. It did not happen because of global warming, but by globalization via international trade in tyres exactly. Eggs were lodged in small water tanks inside the tires. The mosquito arrived in Italy in 1990, then recovered in oil stain and entered France through the border. 15 cases of Chikungunya were reported in 2011 in the PACA region. A team of researchers based in Montpellier is currently monitoring its development. At the same time, entomologists inspect the vicinity of the case, destroy mosquito roosts, and spray insecticides against larval and adult stages. They inform the inhabitants of the area on how to empty the water tanks to limit the densities of the tiger mosquito and the appearance of secondary cases (or outbreaks). The good thing is to drain the small water containers collected at home very regularly (winter and summer). The tiger mosquito has already been spotted in all departments of the region and especially in Herault. To protect yourself, you should know that the female Albopictus stings especially at the beginning and end of the day.
