Although the new crown pneumonia epidemic situation in Hong Kong has slowed down, the number of confirmed cases still fluctuates. There were zero local cases recently, but today (17th) there were 9 confirmed cases, of which 6 were local infections and 3 of them were at the source unknown.

Some political parties have asked the government to implement health codes as soon as possible. However, experts believe that Hong Kong is not the dominant player in the implementation of health codes, and neighboring areas may be discouraged by local cases.

Experts pointed out that it is more suitable to implement the health code after local cases in Hong Kong have been "returned to zero" for 14 consecutive days. However, it is believed that it will be possible to "zero out" at the earliest one month later. They call on the government to strengthen border epidemic prevention and take strict precautions against relaxing measures. The rebound is expected to enable the health code.

The Deputy Director of the Food and Health Bureau, Xu Deyi, said at a press conference today that when the two governments believe that the risk is low and the risks are similar, the health code can be implemented. The time is still immature.

Respiratory specialist Liang Zichao bluntly stated that Hong Kong is not the dominant player in the implementation of the health code. As the surrounding areas are worried about the impact of the epidemic on the local people’s livelihood and economy, "The prerequisite for implementation is that Hong Kong can be in line with the neighboring provinces and cities. There is no local case.” He believes that no local case should be used as an indicator, rather than a case of unknown source, because even if all confirmed cases have a source, they still cannot relax, "because they all represent local transmission." He explained that whether a case can be traced to the source is only reflected in the efficiency of case tracking and the effectiveness of social distancing measures. "It is more than reflecting the epidemic. If there is no lag in tracking, the source is usually traced. Is there an absolute number of local cases? Hard indicators, mid-actual."

Strictly prevent rebound first, and then clear zero

He continued that since the incubation period is generally 14 days, if there are no local cases for 14 consecutive days, it can be regarded as "clearing."

When asked when Hong Kong can reach this goal, he estimated that it will be possible at least one month later. He also said that the most important thing at the moment is to observe whether the government has relaxed social distancing and whether there is any rebound after the resumption of work and classes. Zero, many places will rebound once they are relaxed."

He suggested that the government should implement epidemic prevention measures at the border to prevent cross-infection between passengers and airport employees. "The mainland has done better measures against quarantine exemptions than Hong Kong. If you want to clear zero, you must do a good job in external defense, and local epidemic prevention measures must Continuous, the real-time reproduction rate is lower than 1 (that is, each person can infect less than one person)."

Xu Shuchang: If there is no zero diagnosis locally, neither the Mainland nor Macau will welcome Hong Kong people to cross the border

Xu Shuchang, a government expert consultant and chair professor of the Department of Respiratory Diseases at the Chinese University of China, said that it is difficult to assess when the number of confirmed cases in Hong Kong will return to zero at this stage. There are many cases of unknown origin, and the government is gradually relaxing measures, and the epidemic is subject to change at any time.

He also said that if Hong Kong wants to implement a health code, the ideal condition is that there is no local infection for 14 consecutive days. "If there is no local diagnosis, the mainland and Macau will not welcome Hong Kong people to pass."

He continued that if the health code is introduced, the epidemic situation in Hong Kong becomes unstable again and the validity period of the health code will be shortened.

He cited China and Hong Kong drivers as an example. When the epidemic is stable, the validity period of the health code is 14 days; when it is unstable, it will be reduced to seven days, three days, or even 24 hours.

Regarding when the confirmed cases in Hong Kong will be returned to zero, the co-chairman of the Infectious Disease Advisory Committee of the Medical Association Zeng Qiyin said to himself "Hopefully, I believe it will be returned to zero." The time depends on how hard the government works to find invisible patients and how much the public cooperates. Anti-epidemic.

He said that the second wave of the epidemic in Hong Kong will take 8 to 10 weeks to clear the cases. In response to the third wave of the epidemic, the government has introduced a series of stringent epidemic prevention measures on July 15, including an order for banning food in the evening and masks. .

Calculating from that day, he estimated that it would take 12 weeks at the earliest to quell the third wave of the epidemic. He concluded that the most optimistic scenario would be that the number of cases could be "zeroed" from mid to late October.

Xu Deyi pointed out at a press conference today that the health code software is mature, but it will take time to observe when it can be used. The two governments can implement it only when they believe that the risk is low and the risks are similar.

When asked whether the health code will be implemented on October 1, he said that the public does not need to focus on when to activate it. He reiterated that "when the two governments are assured that the risks are similar and low, more detailed discussions will begin. What time."
