On January 21, Zhong Nanshan, the leader of the national expert group, and He Jianfeng, the director of the Infectious Diseases Institute of the Guangdong Provincial Center for Disease Control and Prevention, attended the press conference of the Guangdong Provincial Information Office.

[16:46] Zhong Nanshan: The new coronavirus has been clearly transmitted from person to person and can be confirmed in Wuhan and Guangdong. In Wuhan, there was mutual infection between medical staff and patients, and there were two families with family members. The virus travels through the respiratory tract and does not affect the distance, but the virus may stick to droplets. Therefore, isolate the patient and keep him away from other people. At present, Guangdong has taken effective quarantine measures. In Zhuhai and Shenzhen, family members have been infected, but no one has heard of and infected others. If there is a second-generation infection, the virus will spread quickly. Seventeen years ago, SARS was due to poor control of transmission. In the crowd, the virus will gradually adapt to the process, and there will be interactions between animals and humans. Especially super communicators, that's a big problem. I went to Wuhan the day before yesterday and went to Beijing in the afternoon to participate in the highest-level prevention and control video conference. Because human-to-human transmission has now occurred, patients must be strictly quarantined, and close contacts must be tracked. This link must be grasped so that it will not spread like SARS. This approach is very correct. To achieve strategic advancement, there is currently no effective targeted drug for new viruses.

[16:15] Li Bin, deputy director of the National Health Commission, will meet reporters in Beijing at 10 am tomorrow morning.

Hong Kong's response to emerging diseases

Expanded reporting standards for suspected cases in Hong Kong

The Hong Kong Government has amended legislation since January 8 to force the Hospital Authority and the Department of Health to report suspected cases related to Wuhan pneumonia, and to expand the reporting guidelines until January 20. If there is a fever, symptoms of acute respiratory infections or pneumonia, Patients who have been to Hubei Province or a hospital in the Mainland 14 days before the onset of illness, or have had close contact with a person diagnosed with new virus pneumonia, are notifiable cases. If someone refuses segregated treatment or is illegal, the maximum fine is 5,000 yuan and imprisonment for half a year.

1. Require Wuhan passengers arriving by plane to fill out a health declaration

From January 21, the Department of Health requires passengers on Wuhan inbound flights to fill out health declaration forms. If passengers meet the reporting criteria, they will be compulsorily referred to public hospitals for isolation and treatment. Refusal to fill out the forms may be illegal, with a maximum fine of 5,000 yuan and half a year in prison.

2. Strengthen port temperature detection

The Department of Health has set up infrared temperature detection at various ports. If the passenger's temperature exceeds 35.5 degrees Celsius, the instrument will issue a warning. The agency also measured the body temperature of the passengers of the two high-speed trains arriving in Hong Kong by Wuhan daily.

3. Public hospitals provide isolation beds and designated clinics

There are 480 negative-pressure isolation beds available in public hospitals. If there is a need to move about 1,400 isolation beds to respond to the epidemic, and if there are confirmed cases in Hong Kong, the HA will consider setting up a designated clinic in each of the 7 networks to handle Wuhan Patients with pneumonia-related cases to reduce the risk of cross infection.

New coronavirus origin unknown

Mainland authorities shared the new coronavirus gene map with the World Health Organization on January 12. Local laboratories can make rapid tests to speed up the identification of confirmed patients. Within one week after the gene map was released, the number of confirmed cases in the country has multiplied. Hong Kong Chinese Xu Shuchang, a chair professor of respiratory sciences at the university, estimates that since new testing technologies can enable hospitals everywhere to find patients, it is expected that the number of confirmed cases, including overseas cases, will continue to increase.

The National Health Commission said on January 19 that the source of the virus could not be determined. Yuan Guoyong, a professor in the Department of Microbiology at the University of Hong Kong, pointed out that the new virus is a Beta-like coronavirus, which is similar to SARS virus in 80%. He estimated that the virus passed from bats to live game meat and then to humans.

According to the report of Zhejiang Health Commission, at least 5 cases of suspected neopneumonia have been recorded since January 17, including those from Zhoushan. All patients need to be treated in isolation.

WHO confirms virus "limited to people"

The WHO confirmed on January 19 that the 2019 new coronavirus is a "limited human-to-human transmission". According to the limited information currently published in the Mainland, two of Wuhan's cases belong to family groups. Male patients who worked in the South China Seafood Market developed the disease first, and his wife had not been to the market, but the same happened 5 days later. According to mainland information quoted by the Center for Health Protection, only 70% of the first 41 confirmed cases have visited the wet market, and some patients have reported that they have not visited the wet market.

CUHK expert Xu Shuchang believes that reflecting the virus has exited the market, it is expected that Wuhan has been infected in many places; Liang Zichao, chairman of the Infectious Diseases Advisory Committee of the Hong Kong Medical Association, pointed out that data shows that there is a large-scale community outbreak in Wuhan, which is more efficient than human transmission. Wei's statement may be higher, and the authorities need to investigate again. He Bailiang, director of the Center for Infectious and Infectious Diseases of the University of Hong Kong, believes that the second round of transmission has already occurred, and it is only a matter of time before a confirmed case appears in Hong Kong. He reminds the public to pay attention to personal hygiene.

Experts worry about the spread of the Spring Festival and Lunar New Year

As the Chinese New Year approaches the Chinese New Year each year, the total number of passengers in the Spring Festival is in the hundreds of millions. Kong Fanyi, director of the Department of Infectious Diseases at the Department of Internal Medicine of the University of Hong Kong, is concerned that a large number of passengers have been in close contact with the same space (such as trains and airplanes) for a long time, or increased the risk of virus transmission .

Professor Guan Yi, director of the State Key Laboratory of Emerging Infectious Diseases of the University of Hong Kong, expects that the Spring Festival will definitely further expand the epidemic, and if patients go around or make the situation out of control. He mentioned that he has played an important role in responding to SARS and Middle East Respiratory Syndrome (MERS) outbreaks. The current disease development is similar to SARS, and the first confirmed case was recorded before the new year. He pointed out that the main outbreak areas of SARS that year were in Beijing, Guangzhou and Hong Kong. The epidemic affected "not reaching its peak." It cannot be ruled out that the outbreak may be more serious than during the SARS period. "If patients go everywhere, we are completely out of control."

However, Guan Yi said that the Hong Kong government has the virus genetic information and corresponding epidemic prevention measures. The most important thing is that suspect cases must be inspected and quarantined immediately to prevent Hong Kong from "reoccupying again".
