Zhong Nanshan expressed his belief that with the strong measures taken by various countries, the global epidemic situation can be brought under control. “I think it should be around the end of April, and the epidemic situation should be down.”
On April 1, Academician Zhong Nanshan was interviewed by Shenzhen Satellite TV. The main contents are as follows:
Zhong Nanshan judges that there will be no second outbreak in China
When talking about whether there will be a second wave of epidemic peaks in China, Zhong Nanshan said that people with asymptomatic infections will not cause major outbreaks.
Zhong Nanshan said that because we have a strong monitoring system, we will immediately isolate the asymptomatic infected persons and isolate and observe the contacts at the same time. If the transmission chain is cut off immediately, there will be no outbreak like the first wave.
Zhong Nanshan anticipates a turning point in the global epidemic at the end of April
Zhong Nanshan expressed his belief that with the strong measures taken by various countries, the global epidemic situation can be brought under control. “I think it should be around the end of April, and the epidemic situation should be down.”
จงหนานซาน: Fuyang patients have a lower chance of infection
การเก็บตัวอย่างน้ำลายเป็นวิธีที่ไม่เป็นอันตรายและไม่เจ็บปวดเพื่อให้ได้ DNA, there are some patients who are discharged from the hospital to detect Fuyang. Zhong Nanshan believes that the nucleic acid detection of the rehabilitation patients only detects some fragments of Fuyang, not the whole virus. นอกจากนี้, patients will produce relatively strong antibodies after recovery, and generally will not re-infect, and the chance of transmission to others is also small.
จงหนานซาน: There is no evidence to prove that asymptomatic infections are highly contagious
Talking about whether an asymptomatic infected person is infectious and how strong the infection is, Zhong Nanshan said that asymptomatic patients have a clear infectiousness, which has been confirmed. อย่างไรก็ตาม, there is no evidence to show whether it is highly contagious.
จงหนานซาน: “Double detection” should be conducted for two key groups of people
Zhong Nanshan said that it is temporarily impossible to prove that asymptomatic infections are highly contagious, and two types of key populations should be “dual-tested”: one is close contacts, and the other is people returning from key epidemic areas.
Zhong Nanshan talks about whether rehabilitation patients will have sequelae
Zhong Nanshan said that it is difficult to tell whether patients with new coronary pneumonia have sequelae after recovery because the new coronary pneumonia outbreak only needs three months before and after the outbreak.
How to detect new coronary pneumonia?
The positive rate of throat swabs in diagnosed patients is roughly 30%-50%. Some time ago, Academician Wang Chen stated in an interview with CCTV that the positive rate of pharyngeal swabs in the diagnosed patients was only 30%-50%; according to the literature report first published by Liu Yanbin Network of West China Hospital of Sichuan University, the Wuhan Red Cross Hospital In 100 cases of new coronavirus pneumonia, pharyngeal swabs and nasal swabs were taken at the same time. The positive detection rate of pharyngeal swabs was 54%, and the positive rate of viral nucleic acid in nasal swab samples was 89%; while the typical cases reported by the media, It was a patient’s throat swab specimen that was tested negative for nucleic acid three times, and a nucleic acid test for a pulmonary alveolar lavage fluid sample was taken during hospitalization after hospitalization.
