Core Viewpoint - The article emphasizes the importance of recognizing and differentiating between dengue fever and chikungunya, both transmitted by mosquitoes, and provides guidance on symptoms, management, and prevention strategies [2][16]. Group 1: Disease Differentiation - Dengue fever and chikungunya are both transmitted by Aedes mosquitoes, but they exhibit distinct symptoms and risks [2][16]. - Typical symptoms of dengue include sudden high fever lasting 2-7 days, severe headaches, muscle and joint pain, and potential bleeding [3]. - Chikungunya typically presents with high fever above 39°C, joint pain that can last for months, and a shorter fever duration [3]. Group 2: Management Guidelines - For fever above 39°C, it is crucial to manage temperature actively, avoiding aspirin due to its potential to worsen dengue bleeding and chikungunya joint damage, with acetaminophen recommended instead [5]. - Hydration is essential, with a daily intake of at least 2000 milliliters, and intravenous fluids may be necessary if vomiting prevents oral intake [6]. - Isolation and protective measures are vital during the first five days of illness to prevent mosquito bites and further transmission [8]. Group 3: Prevention Strategies - Effective prevention involves eliminating standing water where mosquitoes breed, with recommendations to regularly clean and empty containers that can hold water [10][11]. - Personal protection includes using mosquito nets, repellents, and wearing light-colored clothing to reduce mosquito attraction [12][13]. - Travelers to endemic areas should carry mosquito repellent and monitor their health for 12 days post-return, seeking medical attention if symptoms arise [15][16].

Core Viewpoint - The World Health Organization has issued a warning about the global spread risk of chikungunya virus, with 119 countries reporting cases and approximately 5.5 million people at risk of infection [1][2]. Summary by Relevant Sections Global Situation - As of July 23, 2025, there have been 3,195 confirmed cases of chikungunya in Foshan, China, with sporadic cases reported in northern cities, indicating a risk of further spread [1][2]. Prevention Guidelines - Public health experts emphasize the importance of early prevention, diagnosis, and intervention for chikungunya [1][2]. - Recommendations for personal protection include wearing light-colored long-sleeved clothing, using insect repellent containing DEET or Picaridin, and creating a mosquito-free environment at home [3]. Treatment Principles - For symptomatic patients, the primary treatment focus is on symptom relief and preventing complications. Acetaminophen is recommended for fever and pain relief, while aspirin and ibuprofen should be avoided to reduce bleeding risks [5]. - Patients are advised to maintain hydration and limit joint activity during the acute phase of the illness [5]. Immunity and Transmission - Chikungunya virus infection typically provides lifelong immunity, with reinfection being rare. The virus is transmitted only through mosquito vectors, and there is a potential for vertical transmission from mother to child, necessitating heightened precautions for pregnant women [6].
