Core Viewpoint - The article discusses the outbreak of Chikungunya fever in Shunde District, Guangdong Province, highlighting the confirmed cases, symptoms, and the importance of preventive measures against mosquito-borne diseases [1][4]. Summary by Sections Outbreak Details - As of July 21, 2025, Shunde District reported a total of 2,471 confirmed cases of Chikungunya fever, primarily in Lecong, Beijiao, and Chen Village, with all cases being mild [1]. - The outbreak was traced back to an imported case from a worker returning from abroad, leading to local transmission by mosquitoes [1]. Disease Characteristics - Chikungunya fever is caused by the Chikungunya virus (CHIK-V), primarily transmitted by Aedes mosquitoes, characterized by fever, rash, and severe joint pain [1][3]. - The disease was first identified in Tanzania in 1952, and its name means "to become contorted" in the local language, reflecting the severe pain experienced by patients [4]. Symptoms and Comparison with Dengue Fever - Initial symptoms include sudden high fever and severe joint pain, particularly in small joints, followed by a rash that typically resolves within 3 to 5 days [4]. - Chikungunya fever shares similarities with dengue fever in terms of transmission and symptoms, but has a shorter incubation period and faster spread [4]. Vulnerable Populations - Although current cases are mild, special attention is needed for newborns and individuals over 65, especially those with underlying health conditions like hypertension, diabetes, and heart disease, as they are at higher risk for complications [5]. Transmission and Prevention - The virus does not spread directly between humans; transmission occurs through mosquito bites [6][8]. - Effective prevention strategies include mosquito control measures, such as eliminating standing water and using repellents, as well as personal protective measures like wearing long sleeves and using mosquito nets [8][9]. Travel Advisory - Travelers to regions where Chikungunya and dengue fever are prevalent should monitor local health advisories and take precautions against mosquito bites [9].
