Key Points
- China’s CDC top officials, led by Shen Hongbing (沈洪兵), rapidly deployed to Foshan, Guangdong province, to guide and escalate efforts against a localized Chikungunya fever outbreak.
- Response strategy includes aggressive mosquito eradication, environmental sanitation, and a strict “grid-based management” approach to eliminate breeding sites and prevent spread.
- The mission activates a “quadruple responsibility” (四方责任) mechanism, assigning accountability to local governments, departments, institutions, and individuals to contain the epidemic swiftly.
- A multi-pronged approach involves revitalizing “patriotic health campaigns” for public participation in prevention (e.g., removing stagnant water) and upgrading clinical protocols for diagnosis, treatment, and severe case prevention.
China is mobilizing its top public health officials to tackle a localized Chikungunya fever outbreak, offering a masterclass in rapid, top-down epidemic response.
On August 3, 2025, Shen Hongbing (沈洪兵), the heavy-hitter who serves as both Deputy Director of the National Health Commission and Director of the National Administration of Disease Prevention and Control (National CDC), personally led a team to Foshan, a major city in Guangdong province.
Their mission: to guide and escalate the city’s prevention and control efforts against the mosquito-borne virus.
This isn’t just any visit. When leaders at this level show up on-site, it signals a high-priority, no-failure-tolerated situation.
They were joined by other key figures, including Sun Yang (孙阳), Deputy Director of the National CDC, and Tang Yifeng (唐屹峰), Foshan’s Municipal Party Committee Secretary, underscoring the coordinated effort between national and local authorities.
Boots on the Ground: A Look at Foshan’s Prevention Strategy
Shen’s team didn’t stay in a boardroom. They went straight to the front lines.
The delegation visited the Pingbu (平步) and Shajiao (沙滘) communities in Lecong Town (乐从镇), located in the city’s Shunde District (顺德区).
Here’s what they were looking for:
- Mosquito Eradication: How effectively are local teams killing mosquitoes, the vectors of the disease?
- Environmental Sanitation: Are public spaces clean? Are mosquito breeding grounds being eliminated?
- Public Awareness: Do residents understand the risks and know how to protect themselves?
Shen emphasized a strategy of strict grid-based management. This involves dividing communities into smaller, manageable grids to ensure no area is overlooked.
The core directive was clear: aggressively disinfect high-risk zones, eliminate breeding sites for disease vectors, and effectively sever all paths for the virus to spread.

The “Quadruple Responsibility” Playbook: China’s Top-Down Approach
Shen Hongbing framed the mission within a broader political context, referencing directives from General Secretary Xi Jinping. This highlights the national significance of containing the local outbreak.
He called for the full activation of a “joint prevention and control mechanism” built on the principle of “quadruple responsibility” (四方责任).
For those unfamiliar, this is a cornerstone of China’s public management strategy. It assigns accountability to four distinct parties:
- Local Governments: Overall responsibility for their jurisdiction.
- Government Departments: Specific duties related to their function (e.g., health, environment).
- Institutions & Companies: Responsibility for their own sites and employees.
- Individuals: Personal responsibility for their own health and compliance with public measures.
The end goal is simple but ambitious: contain the epidemic in the shortest possible time to protect public health and maintain social stability.
From Drains to Clinics: A Multi-Pronged Attack on Chikungunya
The strategy isn’t just about government mandates. It’s a comprehensive campaign targeting the environment, the public, and the healthcare system simultaneously.
Mobilizing the Masses: The Patriotic Health Campaign
Shen called for a revitalization of China’s “patriotic health campaigns”—a classic public mobilization tool.
This involves encouraging every single household to participate directly in prevention by:
- Overturning pots and jars where water can collect.
- Clearing any and all sources of stagnant water.
The idea is to transform personal responsibility into a collective, city-wide effort, creating what officials call a “rigorous defense line of mass prevention and control.” It’s grassroots public health, guided by top-down directives.
Upgrading the Clinical Playbook
On the medical front, the instructions were just as precise.
Shen stressed the need to:
- Implement Updated Protocols: Ensure all medical facilities use the latest version of the Chikungunya fever diagnosis and treatment plan.
- Improve Testing Quality: Strengthen quality control for diagnosis to avoid false negatives or positives.
- Standardize Treatment: Manage outpatient and emergency departments efficiently to provide standardized care for all cases.
- Prevent Severe Outcomes: The ultimate clinical goal is to prevent any cases from becoming severe or resulting in fatalities.
Boosting Public Awareness with Health Education
Finally, the plan calls for a major push in health education (健康教育).
Using all available channels, the goal is to educate the public on how to protect themselves, recognize symptoms, and seek help.
This proactive communication aims to build a population that is not just compliant but also consciously aware and capable of participating in its own defense.
As China demonstrates its playbook for handling a Chikungunya fever outbreak, it provides a valuable look into a highly organized and scalable public health system designed for rapid containment.
