北京疾控：本地感染基孔肯雅热风险极低 今夏已完成两轮全市灭蚊

Core Viewpoint - The Beijing Disease Control Center has stated that the risk of local transmission of Chikungunya fever in Beijing is extremely low due to the absence of the primary mosquito vectors, Aedes aegypti and a low proportion of Aedes albopictus, and that the disease is preventable and controllable [1] Group 1: Disease Overview - Chikungunya fever is primarily transmitted through mosquito bites, specifically by Aedes mosquitoes, and is not spread from person to person [1] - Infected individuals typically experience mild symptoms, including sudden fever and joint pain, with most recovering within a week [1] Group 2: Mosquito Species and Behavior - Aedes albopictus, known for its distinctive black body and white markings, is more active during early morning and late evening [2] - This mosquito species breeds in small containers of stagnant water, and its activity is generally limited to a 100 to 200-meter radius from its breeding site [2] Group 3: Mosquito Control Measures - Beijing has conducted two rounds of city-wide mosquito control this summer, with a significant 43% decrease in adult mosquito density compared to the same period last year [3] - The city has designated specific weeks for unified mosquito control activities, focusing on cleaning breeding sites [3] Group 4: Preventive Actions - Recommendations for reducing mosquito breeding sites include removing stagnant water from various containers and cleaning up potential breeding areas [4][5][6] - Specific measures include regularly changing water in plant pots and ensuring that containers are covered to prevent water accumulation [5][6] Group 5: Personal Protection - When outdoors, it is advised to wear light-colored long sleeves and long pants, and to use mosquito repellent containing DEET or Picaridin [7][8] - Travelers should check the mosquito-borne disease situation at their destination and prepare appropriate protective measures [8]
