Talk about epidemic control: overseas is still in a high position
Zhong Nanshan said that China's new coronary pneumonia epidemic situation is basically under control, but it is still high overseas. Because nucleic acid testing has not achieved full coverage, it is not clear how many people are diagnosed in Africa. "Confirmed cases in populous countries such as Africa, India and Pakistan are in the climbing stage, while China is in the stage of basic control. Such a contrast will cause imported cases, and there will be patients who are infected after imported from outside."
Zhong Nanshan said that Guangzhou has taken full coverage of nucleic acid detection for foreign personnel entering the spike, which is actually a measure to upgrade foreign defense imports and is related to the current world epidemic situation. It is necessary to adopt full coverage nucleic acid detection and isolation.
"From the perspective of the current world epidemic situation, international students are a very noteworthy group, especially in some developing countries. The epidemic situation is still difficult to estimate. Therefore, international students and their close contacts must pass regular inspections. Agree to come back to class. "Zhong Nanshan said.
Recently, there have been multiple cases of imported cases in Guangzhou. Zhong Nanshan did not think it was a rebound of the epidemic. "What is a rebound? An outbreak that occurs in a large group is a rebound. I do n’t believe that entering from other cities, he has no close contacts. Infectious diseases, no boundaries, early detection is a good thing. Guangzhou takes measures earlier, this is The good thing is not to think of a rebound, but to the practices and results discovered early. "

Talking about asymptomatic infections: not the late characteristics of new coronavirus
The hidden danger of "asymptomatic infected persons" has become a common concern of the public. Zhong Nanshan said that asymptomatic infections are not a feature of the late stage of the new coronavirus. Such people have always existed. "Like the Diamond Princess, many are asymptomatic infections."
"At present, the rule we observe is that patients have symptoms in 3 to 5 days, and the viral load is very high in 5 days." Zhong Nanshan said that the symptoms are a subjective feeling, fatigue is one of the main symptoms of new coronary pneumonia, and everyone responds differently There are subjective reasons for the presence or absence of symptoms.
Zhong Nanshan said that at present, from many overseas import cases, many people have no symptoms of virus infection abroad, and symptoms do not appear during or after arrival in China. This also promotes the society to pay more attention to asymptomatic infected people, "I also reiterate, This is an infectious disease. Do n’t expect the epidemic to disappear, as long as it does not affect life and production. "
Talking about the recurrence of the epidemic: vaccines and human intervention are important
"I absolutely don't believe in natural immunity. This is the opinion of decades ago. Now that people's knowledge and technology are so high, why should they still use this method?" Zhong Nanshan said, the world is racing against time and working hard to develop new crowns day and night The vaccine against pneumonia depends on the vaccine.
Human intervention is important to prevent the recurrence of the epidemic. Zhong Nanshan said, “We used to have a team to make predictions that the epidemic in China will come down in mid-February. In fact, this is really the case because we have strong human intervention. Now many countries are beginning to pay attention to this issue.” Zhong Nanshan believes that the new crown Whether the pneumonia epidemic will occur again depends on the intensity of human intervention, especially government intervention.
"Will this autumn and winter season happen again? I dare not say that it is possible, but it will not be as embarrassed as this time." Zhong Nanshan said that the intermediate host of the new coronary pneumonia is still unclear. It is much more contagious than SARS, but The case fatality rate is not so high, "I don't believe that the current situation will appear early next year, because we already have preventive methods, early diagnosis and early isolation experience."
Zhong Nanshan said that he had exchanged anti-epidemic experience with South Korea and found that South Korea had done a good job. "They had lessons in 2015. MERS caused more than 10,000 infections that year. They were very nervous this time and started screening early. Isolate as soon as you discover it, and do a good job early. " (Finish)
