Date of last update: 2020-06-15 19:40The epidemic situation of the new coronavirus is unsettled. Yuan Guoyong, a member of the government’s expert advisors and a lecturer professor in the Department of Microbiology of the University of Hong Kong, and Du Qihong, a clinical associate professor in the Department of Microbiology of the University of Hong Kong, wrote an article in the Hong Kong Medical Journal on the situation of new pneumonia in Hong Kong.
Yuan Guoyong and Du Qihong mentioned that people in southern China eat a game culture, so Hong Kong has been able to predict a new wave of animal-to-human viruses in the future more than ten years ago. The two expected that the virus would continue to circulate in the summer, and there would be another major outbreak in the winter. Regarding the Luquanlou group in Liyuan Village, Shatian, which recently appeared, they were wary of the need for Hong Kong people to pay attention to the repair and maintenance of pipes, and suggested that the government should test at least one person out of every 1,000 people with symptoms.

Yuan Guoyong and Du Qihong said that animal studies after the SARS show that nearly 40% of the "Chinese horseshoe bats" (Heliobats) can harbor SARS-like coronaviruses, plus the culture of southern China eating wild game. Starting in 2007, it can predict that there will be a new wave of SARS outbreak or other new viruses transmitted from animals to humans in the future.
I believe most patients do not wear masks when infected
The two stated that measures such as wearing masks by the people of Hong Kong, government border control, rapid case tracking and social distance by the authorities have enabled the spread of local cases to be controlled. At present, there are more than 1,000 cases in Hong Kong, only 40% of which are locally diagnosed cases. It is believed that most of the patients did not wear masks when infected.

It is recommended that the government test at least one of the 1,000 people with symptoms every day
However, the article states that Hong Kong cannot be complacent because a super-transmission incident is enough to paralyze the medical system. As the residents of a building recently required emergency evacuation due to a plumbing problem, the two were vigilant to the people of Hong Kong concerned about the maintenance of the plumbing. They specifically mentioned that the Luquan Building in Liyuan Village, where patients live on at least 6 units on different floors, or a harbinger of super-transmission events, should not be simply treated as a group infection. The two believed that the government needed to step up testing in the 18 districts, and recommended that every 1,000 citizens with symptoms of respiratory tract infection should have at least one person tested every day.
Coronavirus has not been able to end or become a seasonal respiratory infection
The article pointed out that due to the low immunity rate of Hong Kong people, it is expected that the virus will continue to circulate in the summer, and there will be a large outbreak again in the winter. The two also mentioned that it is difficult for safe and effective vaccines to be widely available in the coming year. It is estimated that the outbreak will not be completed in a short period of time, and it is likely to become a seasonal respiratory infection coronavirus.
