Southern Chinese City Battles Chikungunya Virus Outbreak with Fish, Drones, and Surveillance Techniques
In the bustling industrial city of Foshan, Guangdong Province, China, a significant public health event has unfolded. An outbreak of Chikungunya fever, a mosquito-borne virus, has been reported with over 8,000 confirmed cases since July 2025 [1][3]. This marks the first major outbreak of Chikungunya in China, involving sustained local transmission primarily due to increased presence of Aedes mosquitoes and lack of population immunity [1][3].
Transmission and Symptoms
Chikungunya virus (CHIKV) is spread by Aedes mosquitoes, which thrive in the Foshan area’s environment. The virus causes symptoms including fever, joint pain, and rash [2]. Genomic analysis of virus samples from the outbreak showed the strains belong to the Central African Clade of the East-Central-South African genotype [2]. Human cases are infectious to mosquitoes during the early symptomatic period, enabling local transmission cycles.
The symptoms reported in Foshan include fever (86.8%), joint pain (81.4%), and rash (65.5%), with no severe illness or deaths documented so far [2]. All cases have been confirmed by RT-PCR and viral genome sequencing for surveillance [2].
Control Measures
To combat the outbreak, a multi-layered containment strategy has been implemented. This includes aggressive mosquito control, patient-level interventions, surveillance and diagnostics, and enforced measures [1][2][3].
- Vector control: Drone-based fogging, fines for noncompliance, use of mosquito-eating fish, and elimination of mosquito breeding sites within 100 meters of case locations [1][3].
- Patient-level interventions: Insecticide-treated window screens, bed nets, and residual repellents applied at patients’ homes to prevent mosquito bites and interrupt transmission [2].
- Surveillance and diagnostics: Active case detection and differential screening from dengue, routine nucleic acid testing implemented in healthcare settings to identify and manage cases promptly [2].
- Enforced measures: Quarantines and household inspections reminiscent of prior COVID-19 responses have been instituted to ensure compliance with mosquito control efforts [1].
Current Status
As of the latest reports, the outbreak has primarily affected the population of Foshan and nearby areas [1][3]. Given the lack of prior immunity to the Chikungunya fever in the population, authorities are closely monitoring the situation.
