The government used the interdisciplinary team of the University of Hong Kong to conduct sewage monitoring and required residents of Fengze Building and Kaihui Building in Choiyun (2) Village in Ngau Chi Wan to undergo mandatory testing. As of yesterday (9th), 9 invisible patients were successfully identified.

The Secretary for the Environment, Huang Jinxing, stated in his blog today (10th) that due to the complex sewage network in the local community, dozens of colleagues from the Drainage Services Department and the Environmental Protection Department have recently supported the selection and sampling of "sewage inspection" sites in the epidemic buildings.

Researchers have so far collected hundreds of domestic sewage samples from sewage collection systems in different regions for nucleic acid testing of the new coronavirus.

In the past six months, the Environment Bureau and the Environmental Protection Department, together with the Drainage Services Department, have actively participated in the interdisciplinary team of the University of Hong Kong in the research and development of methods to detect the new coronavirus in domestic sewage.

Since mid-2020, the team has continued to optimize and validate new methods, work together to support scientific research and exploration, and connect with the Food and Health Bureau and related departments to try to assist the feasibility of community anti-epidemic measures.

An invisible patient was found in the "exploration" of Feng Chak House and Kai Fai House.



Huang Jinxing said that Choi Wan (II) Village is one of the "exploration" research and application cases. At the end of last year, Kwun Tong and Wong Tai Sin districts were hot spots of epidemic concern. There have been many confirmed cases in Mingli Building, which shares many facilities with the adjacent Fengze Building and Kai Fai Building. The team then conducted a trial of sewage virus monitoring in Feng Chai Building and Kai Fai Building, and studied whether there was cross-infection. Invisible patients in the village of the virus, 9 invisible patients were found in two rounds of forced testing.

The local community sewage network is quite complicated. Huang Jinxing pointed out that recently dozens of colleagues from the Drainage Services Department and the Environmental Protection Department have supported the selection and sampling of "sewage detection" related to the epidemic building, including analyzing the distribution of community cases and finding corresponding sewage discharge building plans , Selection of sewage manholes, field inspection and comparison and evaluation, arrangement of sampling contractors, contacting estate management, field sampling operation and quality assurance, freezing temporary samples and express delivery to the laboratory, etc., and in accordance with the general daily habits of residents, field sampling is mostly Start in the early morning.

Researchers have so far collected hundreds of domestic sewage samples from sewage collection systems in different regions for nucleic acid testing of the new coronavirus.

He quoted Lu Zhenlong, an engineer of the Drainage Services Department, as saying, "In a race against time, it is necessary to take a sample of sewage safely and as soon as possible, and deliver it to Hong Kong University for further detection."

No confirmed case. Sewage samples from Fung Chak House, Choi Wan Village, No. 4, were positive for the virus. All buildings must be checked

In addition, one of the sampling contractors is a sewage treatment and environmental protection company. Last year, it also participated in the funding project for tertiary graduates of the Environmental Bureau's "Green Employment Program" under the Government's Anti-epidemic and Anti-epidemic Fund, and recruited young people to "enter the industry."

Huang Jinxing said that some of the newly hired young people of the company have also participated in this sewage "epidemic" work.
