Last updated: 2020-01-25 19:46The outbreak of "Wuhan pneumonia" caused by the new coronavirus continued to spread. The number of infected people in mainland China exceeded 1,300 and 41 died, of which 16 died yesterday. A doctor in Wuhan died this morning.
There have been five confirmed diagnoses in Hong Kong, of which the third confirmed patient had stayed in the non-negative pressure ward for three or four minutes during the consultation at Tuen Mun Hospital. The HA said it might affect other people and was assessing the risk. In addition, one of the diagnoses deteriorated and required a ventilator.
Yuan Guoyong, a professor in the Department of Microbiology of the University of Hong Kong, pointed out that the virus transmission rate is 83%, and the next few days will be the last chance to prevent the virus from spreading to Hong Kong. An analysis of 41 cases in the Mainland of the authoritative medical journal "Acupuncture Needle" pointed out that the virus resembles SARS, with a mortality rate of 15%. The journal also published a study from the University of Hong Kong confirming that the patient was passed down from person to person.
[18:06] Lin Zheng was asked whether the Masking Law and the Director of Health Chen Hanyi still suggested that going out without a mask is related to the judicial review of the Masking Law. Lin Zhengyue stated that there were no political considerations. "You doubt that I count, I should doubt Director Chen."
[17:48] Liang Zhuowei:
All anti-epidemic strategies should be based on science, and there must be no considerations other than science, especially politics.
48 hours ago, the WHO used two days (the original estimate was four or five hours) to open an emergency committee. Discussion lasted eight hours on the first day and six hours on the second day. The conclusion was that the epidemic was very serious, but the public health emergency of International Concern had not yet arrived, and it was clear that travel warnings should not be issued to the mainland of China. There are many scientific considerations behind it.
The people inside are not political, they are all scientific considerations.
Hong Kong's SARS, bird flu, and swine flu. There is no case of H7N9 bird flu in the Yangtze River Delta in Hong Kong. We have never tried customs clearance. Wuhan and its neighboring cities, with a population of 20-30 million, are internationally accepted practices, and are clearly recognized practices.
Are we going to close Hong Kong? Hong Kong is an international hub. Unless we are alone, we close all passengers, not for a specific place. This is based on scientific evidence. This morning, I, Yuan Guoyong, Xu Shuchang, and Professor Fukuda (then the US CDC representative helped Hong Kong to do the 1997 bird flu epidemic), we share the same opinion: customs clearance is not a correct and feasible strategy . I never have political considerations in my public health strategy.
Liang Zhuowei used the Swiss cheese metaphor to mean that although there are many holes in each piece, if many pieces of cheese are stacked together, they will not pass through the holes in a straight line, thinking that multiple measures and multiple approaches can block the epidemic.
[17:36] Lin Zheng: The reporter asked if he would follow other countries or other cities in the Mainland to seal off passengers from Hubei. Lin Zheng Yue'e said that other cities in Hubei Province have no direct flights and high-speed rail to Hong Kong. Impractical, because you can come to Hong Kong through other places. No other factors were considered. These measures will not be affected by the relationship between Hong Kong and the Mainland, and the health of the public will be the first priority.
Some medical personnel called on the authorities to take customs clearance measures, otherwise an industrial operation was initiated. Lin Zhengyue appealed that all sectors of the society should invest in the fight against epidemics. If the medical care is worried about workload, equipment or arrangements after work, I hope you can discuss with us happily, not With fierce action. Maybe everyone used to use fierce action in the past seven months, but now I hope not to use fierce action.
[17:22] Chen Hanyi, director of the Department of Health: The electronic declaration has been introduced in trials. It is being tested in West Kowloon today and hopes to introduce it later. The isolation camp has launched MacLehose Centre and Lei Yue Mun is ready. Other non-governmental organizations have been contacted and the resort will be requisitioned. Fanling has not occupied the public housing Huiming Village, or it can be used as a dormitory for medical staff.
HA: Reduce non-emergency surgery after Chinese New Year
Yang Runxiong, director of the Education Bureau: extended the holiday until February 17th to resume classes, during which the examination and testing activities were cancelled, and the school building was open during the suspension period. Student allowance, originally scheduled for February 15th, will be extended to February 28th.

[17:09] Liang Zhuowei:
Clinical severity
Data were published 36 hours ago in the study journal. Sickness requires hospitalization, with a mortality rate of about 14%, with one death per 7 to 8 people, similar to SARS (then the mortality rate in Hong Kong was 17%).
This is based on the fact that all patients are so serious that they need to be hospitalized. Almost 100% of SARS infections require hospitalization and there will be no persistent invisible patients in the community.
The medical journal "Acupuncture Needles" was also published by Yuan Guoyong's team. There are cases of mild symptoms that do not require hospitalization, and the transmission is potentially risky. Because there are minor cases, the overall mortality rate will not be so high.
Detection methods and basic clinical data
HKU Shenzhen Hospital, some cases are not symptoms, but fever and discharge. Depending on the incubation period, about 6 days, more than 90% of patients, the incubation period will reach 14 or 15 days.
To achieve the above scientific and medical data in Hong Kong, we have made unremitting efforts for 17 years after SARS, and the Food and Health Bureau Research Fund and the Department of Health have also funded us so that we have the current data. The HKU and CUHK teams constantly exchange data with overseas and mainland China. I hope everyone supports the scientists and doctors who work hard. We must now fight the epidemic with a high degree of alertness and a calm mood.
We use a containment policy. We do not see any signs of local transmission, but we must be mentally prepared to have local transmission and a buffer time to slow down the epidemic and allow all contingency measures to be implemented.
call:
1. Wash your hands frequently
2. Hold your mouth and nose while sneezing or coughing
3. Get a flu shot and let medical staff identify if you have flu protection
4. Wear masks, take public transportation and go out to protect yourself and others. Wash your hands before taking off the mask, and then wash your hands after folding the mask in the plastic bag. It is called for wearing glasses. If you have no nearsightedness, you should consider wearing flat glasses to protect yourself.
[17:00] Liang Zhuowei, Dean of the University of Hong Kong:
Communication power
In the past few days, WHO has held emergency meetings. Our team's research, published a mathematical model last week, and last night we communicated with the WHO headquarters and more than ten different countries in the world as epidemiological teams. The basic reproductive rate, this outbreak, is 2, that is, each infected patient spreads to 2 close contacts on average, and each patient generates two.
By extension of doubling time, the number of infections will double in one week. That is about the same as SARS in 2003. The basic reproduction rate for SARS is 2 to 3, and the doubling time is 7 to 8 days. Wuhan pneumonia is by no means weaker than SARS. In 2009, the swine flu reproductive rate was about 1.4 to 1.5, but the time for swine flu to double was doubled. Therefore, the epidemic must not be taken lightly.
There is no local transmission in Hong Kong. There are temporarily imported cases. At present, the containment strategy should continue to be used. The imported cases should be isolated and treated as soon as possible. Swine flu was blocked in 2009. The first imported case from Mexico on May 1st was successfully delayed until the 40th day before the first local infection, which waited until the epidemic situation slowly receded.

[16:37] Lin Zhengyue met with reporters including Director of Food and Health Bureau Chen Zhaoshi, Deputy Director Xu Deyi and Director of Education Bureau Yang Runxiong. She pointed out that from the meeting at 9:30 this morning to the end of the meeting, she heard the opinions of Liang Zhuowei, Yuan Guoyong, and Xu Shuchang.
Lin Zhengyue announced the establishment of six major strategies:
1. Improve the epidemic prevention mechanism and organizational structure. Contingency plans are alert, serious, and urgent. Will now be promoted to the highest level, Urgent. There is the Chief Executive's Steering Committee and Command Center, which has set up four working groups: the Epidemic Prevention and Control Working Group (led by the Director of the Food and Health Bureau), the Contingency Working Group (led by the Chief Secretary for Administration), and the Public Participation Working Group (Home Affairs Bureau Secretary-General), Anti-epidemics Working Group (Leaded by the Secretary of the Constitutional and Mainland Affairs Bureau).
The Chief Executive has led the Steering Committee and Command Center and appointed four people, Liang Zhuowei, Yuan Guoyong, Xu Shuchang, and Fukuda Keiji.
2. Strengthen the control of entrances and exits and control the spread of the epidemic. Indefinitely suspend flights and high-speed trains to and from Wuhan; expand the Mainland's entry health declaration to all ports; take the temperature of departing people to Shenzhen, Macau, and Zhuhai for priority treatment. Updated tourism health advice, the entire Hubei Province is calling on citizens not to go. Suspend all sports activities sponsored by the SAR Government to the Mainland.
3. Cancel large-scale events. Cancel the Standard Chartered Marathon, Lantern Festival, and the Spring Festival of the SAR Government. Call on other NGO sponsors to follow along.
4. Delays in elementary and secondary schools, kindergartens, kindergartens and special schools, which will resume classes until February 17. Evaluate later. Colleges and universities should strengthen relevant measures. Social welfare facilities, residential homes, and increasingly service centers need not be closed for the time being, because many disadvantaged groups need these services. The authorities provide additional resources to enhance cleaning, and visitors must take temperature and wear masks.
Public facilities under different government departments, such as playgrounds, swimming pools, libraries, markets, etc., will be cleaned more frequently, and bobo pools will be temporarily closed. Public transport agencies and private property management have strengthened epidemic prevention. Strengthen the personal hygiene of Hong Kong citizens.
Contact a mask supplier to ensure that demand is met in the short term. Suppliers will do their best to find suitable sources in the Mainland and other regions. The Mainland is the main source of supply and has personally sent a letter to the State Council asking for supply.
5. Strengthening anti-epidemic facilities and services such as the Department of Health and the Hospital Authority.
6. Resources are not a limitation. As long as there is a need, for the health of the public, resources will not be regretted.

[15:45] It is understood that the government will explain whether the Standard Chartered Marathon is postponed.
[15:00] Chief Executive Lin Zheng Yue'e met with reporters at 4:30 this afternoon to explain the latest epidemic situation.
[14:05] On the first day of the Chinese New Year, many pharmacies were closed. A pharmacy in Mong Kok opened its own market. A box of N95 medical masks was found at 1,400 yuan.
[14:00] Twenty-two provinces (municipalities, autonomous regions) across the country initiated the highest level of "level one response", Hong Kong still maintained the second level of "severe" level, and Ocean Park and Disneyland were still open.
[13:44] Tuen Mun Hospital hits directly: The patient stayed in a non-negative pressure ward, and a man was sent to an isolation ward.
[13:00] Three cases were confirmed in Malaysia, and the patients were family members of patients diagnosed in Singapore.

[11:30] Zhong Jianli pointed out that after receiving a call from the infection control director of Tuen Mun Hospital this morning, there was a third case where there was a need to "see it clearly" in the emergency department's treatment process. He arrived at the emergency room on the evening of the 23rd. Since there were two negative-pressure wards in use in the emergency room, the patient was placed in a traumatic room. The patient stayed for three to four hours, and after inspection, it was found that the room was not negative. Patients have a chance to be affected. "I have asked colleagues and experts to look at the whole process and see how much risk it will affect other patients.
Zhong Jianli pointed out that there is a small area outside the room, waiting for X-rays, not for the densely populated lobby. The Centre for Health Protection was notified for a risk assessment and failed to answer how much the risk was. However, the room used by the patient will be thoroughly disinfected before being used again.
When asked about the difference between a negative pressure ward and an ordinary ward, Zhong Jianli said that negative pressure is to isolate airborne pathogens, such as chicken pox and lung diarrhea. Wuhan pneumonia is a droplet transmission, mainly within three feet. Wuhan pneumonia should be treated in a negative pressure ward, mainly because it is afraid of aerosolization measures such as sputum, it will turn droplets into airborne in a short time, so it is necessary to be in a negative pressure ward. Therefore, I will go to Tuen Mun Hospital immediately to see clearly.
Zhang Zhujun said that the daughters of the fourth and fifth confirmed patients had fevers about the same time as their parents.
Asked to shut down all amusement facilities in multiple provinces in the Mainland, Guangzhou required all passengers in Wuhan to be isolated, and Hainan required all passengers in Hubei to be isolated.
[11:15] Press conference of the Center for Health Protection
Dr. Zhang Zhujun, Director of the Department of Infectious Diseases, Centre for Health Protection, Department of Health, and Dr. Zhong Jianli, Director of Quality and Safety of the Hospital Authority, met with reporters.
Zhang Zhujun described the epidemic as menacing, and called on citizens to wear masks.
Zhong Jianli said that there were 62 new suspected cases yesterday and 107 people were hospitalized for observation. He said that the five confirmed patients were in stable condition, and one of them was slightly worse. This morning, he will use an oxygen machine to assist breathing . There were 603 negative-pressure beds, with a usage of 40%; the negative-pressure wards increased from 290 to 325, with a usage of about 60%. Worried about more patients after the Spring Festival holiday, the hospital will be more stressed. There are five medical colleagues in public hospitals reporting because of the reporting mechanism. They will detect the new coronavirus and the situation is basically stable. Two of them have had a cold but have been to Shenzhen Hospital. Some colleagues are wearing full equipment, but have contacted the patient and had a cold. So isolate first. One has been discharged, three have tested negative for the new coronavirus, and the others are watching. Zhong Jianli clarified that she would not arrange pregnant employees to work in high-risk places. For example, negative pressure rooms and shunts are high-risk, but there are other places in the emergency department that are not high-risk. They will consider colleagues' concerns and their own ideas.
There are currently two medical practitioners in isolation, and Zhong Jianli clarified that there is no need to take a big vacation for isolation.
