In the heart of China's Guangdong province, particularly in Foshan city, a significant outbreak of Chikungunya fever has been reported since June 2025. With over 8,000 confirmed cases as of August 2025, this outbreak marks one of the largest in China's history [1][3][4]. The rapid spread and sustained local transmission are notable features of this outbreak.
The Chikungunya virus is transmitted by Aedes mosquitoes, whose populations have been amplified by monsoon flooding and favorable environmental conditions [2]. This outbreak is a stark reminder of the role these environmental factors play in the spread of infectious diseases.
While China grapples with this outbreak, Russia currently faces a potential risk from Chikungunya. As climate change brings warmer temperatures and increased rainfall, the geographic range of Aedes mosquitoes is expanding, potentially increasing the risk of Chikungunya spread into regions such as Russia [2]. However, it is important to note that as of mid-2025, there is no direct evidence of local transmission of the virus in Russia.
Symptoms of Chikungunya include severe joint and muscle pain, fever, swelling, nausea, rash, fatigue, and headache [5]. The incubation period for the disease is typically four to seven days. Fortunately, Chikungunya usually does not cause serious complications.
In response to the outbreak in China, China has implemented several prevention and control measures. These include aggressive mosquito control efforts using drone-based fogging, household inspections, enforced bed-netting, and legal penalties for violating mosquito control guidelines [1]. Public health campaigns also recommend protective behaviors such as wearing long sleeves and pants, using DEET-containing insect repellents, and employing mosquito netting, especially for vulnerable groups like infants [2]. Quarantine and containment strategies reminiscent of COVID-19 protocols aim to reduce human-mosquito contact [1]. Vaccination is recommended by the CDC, particularly for travelers and long-term residents in outbreak areas [2].
For regions at potential risk, such as Russia, preventive measures should focus on surveillance for Aedes mosquito presence and virus introduction, public education on mosquito bite prevention, preparedness for vector control programs, and monitoring travel-related cases to detect any introduction early [6].
This year, the disease is spreading in South Asia, on the Indian Ocean islands, Madagascar, Somalia, and Kenya. Chikungunya fever is most commonly reported in South American, Asian, and African countries [6].
Russia's consumer protection agency has warned of a potential threat of Chikungunya infection being brought into Russia due to the outbreak in China. Vigilant surveillance and preventive actions remain essential to minimize future risk [1][2][3][4].
