Hong Kong’s disease prevention authorities have confirmed a new locally transmitted case of Chikungunya fever in a 23-year-old woman residing in Sheung Wan, prompting immediate and decisive public health actions across the Central and Western District to curb potential community spread. The patient, who lives on Queen’s Road West, experienced initial joint discomfort on November 27, 2025, followed by a fever and rash. She was admitted to Queen Mary Hospital on December 1st, where laboratory testing verified the viral infection. She is reported to be in stable condition, and authorities have begun rigorous epidemiological tracing and vector control operations.
Local Transmission Confirmed
The Centre for Health Protection (CHP) classified this incident as a local case after determining the woman had no recent travel history during the necessary incubation period. Initial investigations suggest her usual residential and activity areas do not overlap with locales previously linked to other recent cases, indicating a potentially isolated transmission event. This latest confirmation brings Hong Kong’s total number of Chikungunya cases this year to 77, with eight being locally acquired infections.
Following the confirmation, the CHP and the Food and Environmental Hygiene Department (FEHD) immediately mobilized resources. Inspections were conducted near the patient’s residence, specifically around the Queen’s Road West, Morrison Street, and Hollywood Road vicinities. This involved targeted surveillance and large-scale mosquito mitigation efforts aimed at drastically reducing the presence of the
Aedes mosquito, the primary vector for the virus.
Public Action and Surveillance
To proactively manage the risk of further spread, the CHP is urging individuals who were in the affected Sheung Wan area on or after November 15 and who have developed symptoms—including fever, joint pain, or rash—to seek medical attention promptly.
Community Engagement and Consultation:
- From December 4, a CHP health consultation booth will be operational daily between 9 a.m. and 6 p.m. at the main entrance of the Sheung Wan Civic Centre to assess symptomatic individuals.
- The dedicated CHP inquiry hotline (2125 2373) is running daily from 9 a.m. to 8 p.m.
- Outreach teams are engaging residents to raise awareness of symptoms and emphasize the importance of household hygiene and source reduction.
Furthermore, healthcare providers, educational institutions, and primary care doctors in the affected districts are being updated with the latest guidance. They are instructed to remain vigilant for compatible symptoms and arrange timely testing to ensure quick containment.
Combating High-Risk Hotspots
Separate from the Sheung Wan case, authorities continue to address an existing high-risk transmission area around the Tsing Yi Nature Trails, where several previous cases reported being bitten by mosquitoes while hiking. The FEHD has significantly escalated its eradication program in this area using advanced technologies.
Mosquito control efforts on Tsing Yi include:
- Intensive adulticidal fogging and deployment of large ultra-low-volume foggers.
- The trial use of specialized equipment, including a robotic device, to enhance operational thoroughness in difficult terrain.
- Removal of standing water sources and application of larvicidal oil or biologics where water cannot be drained.
Inter-departmental anti-mosquito task forces are meeting regularly across Hong Kong to synchronize enhanced prevention and control strategies, highlighting the government’s commitment to controlling vector-borne diseases through coordinated, multi-district efforts. Visitors to high-risk areas are strongly advised to use insect repellent and wear long sleeves and trousers.
