Last update date: 2020-08-08 09:09The government announced that it will launch a voluntary free test for all people, which is estimated to be implemented in two weeks. Xu Shuchang, an expert consultant to the Government’s Anti-epidemic Steering Committee and Chair Professor of Respiratory Department of CUHK, said that the successful control of the epidemic in Beijing, Wuhan and Hubei, etc., is because in accordance with the stay-at-home order, invisible spreaders and patients do not travel in the community.

Xu Shuchang explained in the Hong Kong and Taiwan program "Saturday Accountability" that voluntary testing for all people is a backup plan. Because the nationwide testing on the mainland has successfully controlled the epidemic, it is because of mandatory enforcement and cooperating with the stay-at-home order. However, it is difficult for Hong Kong to stop the society for one week to enforce: "Restrictions. If resistance is strengthened, the public may not accept it."
He explained that asymptomatic people may also carry the virus. I believe that with the assistance of the company and the Mainland during the national test, the diagnosis time will be more than the current two to three days required by the HA.
Xu Shuchang, an expert consultant to the Government’s Anti-epidemic Steering Committee and Chair Professor of Respiratory System of CUHK, suggested that when Hong Kong implements universal testing, employers should arrange employees to work at home as much as possible to control the flow of people, cut off the chain of transmission and find invisible spreaders.

He bluntly said that the nationwide testing has a lot of resources and will only be carried out once; while specific, high-risk groups can be tested cyclically. For example, staff in residential care homes for the elderly may be tested periodically.
As for the testing method, Xu Shuchang believes that the company in charge should decide, but it is possible to consider different methods based on age or citizen's voluntary choice. For example, he pointed out that if the elderly have to take blood-thinning medicine due to chronic illnesses, the nasopharyngeal swab test (commonly known as "puffing the nose") may be more prone to nosebleeds and other discomforts. Deep throat saliva can be used; as for those who do not know how to vomit People with sputum should use the nasopharyngeal test.
Mainland personnel coming to Hong Kong to assist in the implementation of universal testing has caused controversy. However, Xu Shuchang believes that Hong Kong has limited resources. Without assistance from the Mainland, it is impossible to increase the amount of testing so much. The relevant personnel have "fire fighting experience" in the Mainland and it is only a short-term cooperation. acceptable.
There are suggestions that people who test negative for the whole nation can be exempted from social restrictions within the specified time limit. Xu Shuchang bluntly suggested that it is not feasible. He used the earlier diagnosis of a cross-border driver as an example, saying that he was negative when he entered the Mainland, but he was diagnosed after returning to Hong Kong. Therefore, the public was tested negative when he was tested and could be diagnosed with infection later. "It is impossible to be negative today. Nothing happened for a few days."
