基孔肯雅热（Chikungunya fever，CHIK）是由基孔肯雅病毒引起的一种蚊媒传染病，主要通过感染病毒的伊蚊（埃及伊蚊和白纹伊蚊）叮咬传播，急性 期患者、隐性感染者和感染病毒的非人灵长类动物是本病的主要传染源。目前尚无直接人传人的报道。 什么是基孔肯雅热？ 这种病怎么传播？ 基孔肯雅热的传播途径和登革热相同，都是通过携带病毒的媒介伊蚊叮咬传播。山东省的媒介伊蚊主要是白纹伊蚊，也就是"花斑蚊"，城乡分布广泛。这 种蚊子一般在白天叮咬人，活动高峰在日出前后1～2小时和日落前2～3小时。伊蚊在叮咬感染病毒的人或动物后，病毒在蚊虫体内经过2至10天的繁殖并 到达唾液腺内增殖，再通过叮咬传播出去。病毒可在蚊虫体内存活较长时间。 这种病通常在哪儿发生？ 人群普遍易感，感染后可获得持久的免疫力。基孔肯雅热在全球热带和亚热带地区流行，已有119个国家和地区发生过本土传播病例。东南亚、南亚、非 洲和美洲部分地区疫情持续活跃。近期广东省发生输入疫情引发的本地传播。 潜伏期几天？临床症状主要有哪些？ 潜伏期为1～12天，多为3～7天。患者症状主要表现为突然发热（≥39℃），部分患者热退后再次出现发热；经常伴有严重关节痛， ...

Core Viewpoint - The World Health Organization (WHO) has issued a warning regarding the spread of chikungunya virus, urging countries to prepare for potential outbreaks as approximately 5.5 million people are at risk globally, with 119 countries reporting cases [1] Group 1: Current Situation - As of July 22, over 3,000 confirmed cases of chikungunya have been reported in Foshan, Guangdong Province, since the first case was detected on July 8 [1] - The Beijing Center for Disease Control has noted occasional imported cases, indicating a persistent risk of case importation due to increased international exchanges [1] Group 2: Transmission and Symptoms - Chikungunya is primarily transmitted through mosquito bites, specifically by Aedes mosquitoes, with no evidence of human-to-human transmission [2] - Symptoms include fever, rash, and severe joint pain, with most patients experiencing mild cases that typically resolve within 5 to 7 days [4][3] - The clinical characteristics observed include low to moderate fever, rash appearing within 1 to 3 days, and significant joint pain, particularly in the fingers and ankles [3][4] Group 3: Prevention Measures - Key prevention strategies include eliminating mosquito breeding sites, such as standing water, and using household mosquito repellents [6] - Recommendations for personal protection include installing screens on windows, using mosquito nets while sleeping, and wearing light-colored long-sleeve clothing outdoors [6] - Individuals exhibiting symptoms such as high fever, severe joint pain, or rash, especially with a history of mosquito bites or travel to affected areas, should seek medical attention promptly [6]

Group 1 - The article emphasizes the importance of community participation in controlling mosquito breeding environments to prevent diseases like dengue and malaria [1][2] - Mosquitoes go through four life stages, and eliminating standing water is crucial as even a bottle cap of water can breed hundreds of mosquitoes [1][2] - Regular cleaning of potential water sources can reduce mosquito density by over 80% [1] Group 2 - In community and park settings, measures such as filling low-lying areas and regularly cleaning ponds are recommended for ecological mosquito control [2] - Physical mosquito control methods, such as using mosquito nets and electric mosquito swatters, are highlighted as safe and effective [2] - Chemical control methods should be used judiciously to avoid environmental contamination and to prevent mosquitoes from developing resistance [2] Group 3 - Travelers to malaria-endemic regions are advised to carry mosquito nets and repellents, and to seek medical attention if they exhibit symptoms of malaria or dengue upon returning [3]

Core Points - The article discusses the increased activity of mosquitoes and other insects during summer, highlighting the health risks associated with their bites, including potential infections and severe reactions [2][3][4][5][6][7][8][11]. Group 1: Tick Prevention and Treatment - Ticks are prevalent in summer, especially for outdoor workers, and can cause severe health issues if not handled properly after a bite [3][4]. - It is advised not to pull ticks out forcefully to avoid leaving parts inside the body, which can lead to infections [3]. - Proper removal techniques include using fine-tipped tweezers to pull the tick straight out and seeking medical assistance if necessary [3][4]. Group 2: Prevention of Hidden Winged Insects - Hidden winged insects, such as the "hidden wing bug," can cause skin reactions if crushed on the skin, leading to severe dermatitis [5][6]. - To avoid bites, it is recommended to gently blow or brush these insects away instead of swatting them [5][6]. - Treatment for skin damage from these insects varies based on severity, with options ranging from mild topical treatments to antibiotics for severe cases [5][6]. Group 3: Mosquito Bites and Reactions - Mosquito bites can lead to varying reactions, with some individuals experiencing significant swelling and redness [7][8]. - Factors influencing mosquito attraction include body temperature, sweat, and carbon dioxide output, making certain demographics more susceptible [8][10]. - Preventive measures include maintaining cleanliness, using repellents, and wearing light-colored clothing to deter mosquitoes [11].
