The last update date: 2020-08-08 11:17Yuan Guoyong, a government expert consultant and chair professor of the Department of Microbiology of the University of Hong Kong, criticized in a commercial TV program that the government's relaxation of a number of epidemic prevention measures in mid-June was a big mistake. He explained that more than 2,800 people were diagnosed in the third wave of the epidemic in Hong Kong, mainly local cases, which are believed to be caused by exemption from testing. In June, the Hong Kong government relaxed epidemic prevention measures. The citizens were lax and the streets were crowded. About one adult did not. Wearing a mask is obviously a big mistake. He emphasized that the first thing to do is to do a good job of checkpoints. Even if there are fish that slip through the net, they should not be spread in the community.

Yuan Guoyong said in a commercial program that the current wave of epidemics began to approach its peak on the 17th of last month and is now beginning to decline, which proves that the tightening of epidemic prevention measures has begun to take effect. However, due to the current insufficient number of tests, it is expected that the number of confirmed cases will remain at 80 for some time. Many cases.
He emphasized that the virus is very contagious, and unless there are quite targeted measures to ensure the control of high-risk group transmission, and there are sufficient virus tests, the epidemic prevention measures cannot be relaxed. He reiterated that ventilation in restaurants is very important. The law only requires 1 to 2 air changes per hour. He believes that it should be increased to 6 to 10 times with powerful exhaust fans to reduce the chance of spread of the virus. The number of people at the table, otherwise "I will come back when I relax.

National testing is a good policy
The Hong Kong Government announced that it will launch a voluntary free test for all people, which is estimated to be implemented in two weeks. Yuan Guoyong pointed out that there are still dozens of confirmed cases in Hong Kong every day, but the time for testing and tracing to isolation is too long. He described voluntary testing for all people as a good policy. "People who want to be tested can be tested immediately," which is what Hong Kong expects in the past 5 months. Do, but can't do. He believes that 500,000 tests per day with the assistance of the Mainland is sufficient, but he is not sure how many people are willing to test, so the effect is unknown.
As for which method to use for detection, he believes that the focus is on correct and effective sampling. Some people think that it is not appropriate to allow mainland personnel to come to Hong Kong to assist in testing. Yuan Guoyong believes that the most important thing is to act in accordance with the law and maintain the original testing level. Testing must be done in a certified laboratory in Hong Kong, so there is no need to worry.

The United States is expected to launch a new pneumonia vaccine by the end of this year. It is expected that Hong Kong will have to wait another 9 to 12 months. Yuan Guoyong urged the public to continue to work hard to take adequate preventive measures. Regarding some people worrying about the quality of vaccines in the Mainland, Yuan Guoyong said bluntly that, regardless of where the vaccines come from, the most important thing is to have scientific data to prove their effectiveness.
High risk in the market, the virus survives for a long time in the cold block of the fish stall
Hung Hom Market and To Kwa Wan Market broke out in groups, but the environmental samples taken from the two markets all tested negative for the novel coronavirus. Yuan Guoyong took the Hung Hom Market as an example, saying that it might have been cleaned too well and too quickly after the outbreak, and the source was not found. He emphasized that the markets are generally hotter. People tend to remove their masks. In addition, they will speak loudly when bargaining, which increases the risk of spreading droplets. In high-risk areas, most fish stalls use cold pieces to keep fish fresh. "When bargaining, the virus drops. You can survive in the cold block for a long time." He urged the public to wear masks correctly and wash their hands frequently. In addition, markets should also maintain ventilation and collect heat for citizens who enter to reduce risks.
He also said that mice had been seen during the inspection of the Hung Hom Market, and cats that love to hang around in fish stalls may also be infected by humans and spread the virus. However, he emphasized that humans should respect the moving life of wild animals. Cats and dogs are human friends, and humans pass the virus to them. Therefore, even if the animal is sick, it should be treated and not killed or abandoned.
