The return of the Aedes aegypti mosquito in the French Riviera, specifically in the Alpes-Maritimes, is a cause for concern. This species, known for its ability to transmit diseases like dengue and chikungunya, is expected to make its grand entrance around April 20th, marking the beginning of a challenging season for residents and health authorities alike. The article highlights the importance of understanding the mosquito's behavior and the potential risks associated with its presence. The Aedes aegypti mosquito, which thrives in urban environments, requires water for its larvae to develop and a mild climate to resume activity. The recent weather conditions, including heavy rainfall and slightly above-average temperatures in February and March, have created favorable conditions for the mosquito's survival and reproduction. The focus is on the Aedes aegypti, as the Aedes detritus, another winter mosquito, is not a primary concern for health authorities. The Aedes aegypti's eggs, which are different from those laid during the spring and summer, will hatch, and the larvae will develop more slowly, taking at least a month instead of a week. The first adult mosquitoes are expected to emerge around April 20th, with their population increasing significantly by May. The article emphasizes the need for vigilance and proactive measures to prevent the spread of diseases. The region has experienced a significant outbreak of chikungunya, with 141 cases in Antibes, the largest ever recorded in metropolitan France. This outbreak, along with another in Fréjus, accounted for 60% of the country's chikungunya cases. The article also mentions the importance of eliminating mosquito breeding sites and adopting preventive measures, such as limiting stagnant water and using mosquito nets. The potential for long-term symptoms of chikungunya is a significant concern, with up to 20% of patients experiencing persistent joint pain months after infection. The article features personal accounts of individuals who have suffered from prolonged symptoms, highlighting the impact on their daily lives. The medical community is working to address these post-infectious syndromes, but the lack of specialized care and awareness among the public poses challenges. The article concludes by emphasizing the increasing risk of arboviral diseases, such as dengue, chikungunya, and West Nile, due to climate change. The French Riviera's exposure to these diseases is a growing concern, and the need for proactive measures to prevent their spread is crucial.
