Current Status of Disinfection Equipment and Disinfectants Used by Epidemic Prevention Personnel

At present, as the COVID‑19 pandemic continues to deepen, the need for daily disinfection among public health workers and office employees has become increasingly urgent. It is now clear that the pandemic will persist and the virus will continue to evolve and generate new variants; yet life must go on, and prolonged lockdowns and isolation are simply not feasible. The stark contrast between the “lying flat” approach adopted by some foreign governments and the Chinese government’s stringent prevention‑and‑control measures has led to vastly different outcomes.
We have all undergone numerous large-scale nucleic acid tests, yet localized outbreaks continue to flare up one after another, significantly impacting both our daily lives and work. In response to the pandemic, every sector has made tremendous contributions: for instance, trains entering the country are equipped with spray‑disinfection systems; truck containers have dedicated disinfection lanes; mail and parcels are processed through UV‑disinfection units; fresh produce is treated with spray‑disinfection machines; and various types of protective gear have become standard equipment. However, the most critical component—the personnel disinfection system—has yet to be deployed on a large scale. The main reasons are as follows:
1. Personnel turnover is significant, activities are dispersed and difficult to consolidate, and a single disinfection effort may not be thorough.
2. Chemical disinfectants It has strong oxidizing properties (causing fabric to fade) and its irritating odor poses a significant hazard to the human respiratory tract.
3. Automated disinfection equipment that uses the aforementioned disinfectants is susceptible to corrosion, has low reliability, a short service life, and excessively high costs.
Finding alternatives to chemical disinfectants and developing durable automated disinfection systems has become the bottleneck in addressing this issue.
At the beginning of the year, we joined forces with the Zhuhai Jingshi Beizhong Institute of Science and Technology to tackle this challenging problem. They successfully addressed the issue of using traditional Chinese medicine extracts to inactivate viruses; moreover, the formulation is non-irritating to the respiratory tract and skin, and when sprayed onto the body, it releases the distinctive aromatic fragrance characteristic of Chinese herbs. Taste.
As a herbal extract, this disinfectant delivers gentle yet long-lasting efficacy, with an optimal aerosol particle size of 10 µm or smaller; conventional high-pressure atomization simply cannot meet these requirements. Based on these characteristics, we have specially designed a fully automated aerosol disinfection system that precisely controls spray volume and atomization quality. Currently being successfully implemented at the Fifth People’s Hospital of Zhongshan, we hope it will effectively address the challenges associated with personnel disinfection systems.
