Core Points - Chikungunya fever is a mosquito-borne disease caused by the Chikungunya virus, primarily transmitted through bites from infected Aedes mosquitoes, with no direct human-to-human transmission reported [1] Transmission - The transmission route of Chikungunya fever is similar to that of dengue fever, primarily through bites from infected Aedes mosquitoes, particularly the Aedes albopictus, which is widely distributed in urban and rural areas [4] - Aedes mosquitoes typically bite during the day, with peak activity occurring 1-2 hours before sunrise and 2-3 hours before sunset [4] - The virus can survive in mosquitoes for an extended period after they bite an infected person or animal, with a replication period of 2 to 10 days before it reaches the salivary glands [4] Geographic Distribution - Chikungunya fever is prevalent in tropical and subtropical regions, with local transmission cases reported in 119 countries and regions globally, particularly active in Southeast Asia, South Asia, Africa, and parts of the Americas [5] - Recent local transmission cases have been reported in Guangdong Province, China, following imported cases [5] Clinical Symptoms - The incubation period for Chikungunya fever ranges from 1 to 12 days, with most cases occurring between 3 to 7 days [6] - Symptoms include sudden high fever (≥39°C), severe joint pain (especially in the wrists), and a rash that typically appears 2-3 days after fever onset [6] - The overall duration of the illness is usually 5 to 7 days, with most patients recovering within a week, although joint pain may persist in some cases [6] Prevention Measures - Effective prevention includes mosquito control measures, such as avoiding areas with high mosquito activity, using mosquito nets, and installing screens on windows and doors [8] - Eliminating breeding sites for Aedes mosquitoes by removing standing water and using insecticides in areas where water cannot be removed is crucial [9] - Personal protective measures include wearing light-colored long-sleeved clothing, avoiding mosquito breeding areas, and using repellents [10] - Travelers are advised to monitor health for 14 days after returning from areas with Chikungunya outbreaks and to seek medical attention if symptoms arise [12]
