1、 Many schools around the country do not return to school
Recently, Nanjing University of Aeronautics and Astronautics, Nanjing Agricultural University, Huazhong University of science and technology and other universities have issued the notice of "no return to school". The offline opening process of the university is slow. However, some Chinese foreign cooperatively run universities have completely abandoned the opening of this semester and moved all courses to the Internet. The common points of the back to school arrangement of the above-mentioned universities are: the university basically tends to reply online to undergraduates and finish papers at home; the master and doctoral students who need to complete experiments and other offline operations are the mainstream of back to school; and the other grades basically tend to maintain the status of Online teaching. In short, people who have to be in school to complete research tasks such as experiments can basically not return to school. Kunshan Duke University has decided to extend the online teaching of master's programs and undergraduate programs to the end of the spring semester. In addition, Xijiao Liverpool University in Suzhou, Beijing Normal University Hong Kong Baptist University United International College in Zhuhai, as well as Southwest Petroleum University (undergraduate) and other universities have also issued "no return" notice. According to the Internet, Wenzhou Kean University, Shanghai New York University and other Chinese foreign cooperatively run universities have also issued relevant "no return to school" notices.
On novel coronavirus pneumonia, Beijing city education and Industry Commission spokesman Li Yi said in a news conference on April 14th in Beijing, that the University and kindergartens would not return to school. There is no timetable for the opening of universities in Beijing.
It is reported that the first batch of college students in Xinjiang, Shanxi, Qinghai and other places have successfully returned to school. Meanwhile, Ningbo Nottingham University has carried out the whole process of back to school drill, simulated various emergencies, and is continuing to improve the work plan of students back to school.
Facing the employment test, what are the graduates' anxieties? What are the solutions to the key and difficult problems given by relevant policies? Guangming Daily invited the person in charge of the Ministry of education and employment guidance experts to deeply analyze the "gift package" of employment policy for graduates, and summed up the "four word formula" of this year's College Students' employment. Fast: take immediate action to alleviate employment anxiety; long: it is necessary to take a broad view in job selection. The government and society are making every effort to expand employment channels. College graduates should not only seek for the long term, but also be busy at the moment; multi: multi hand preparation is not panic, that is, multi-channel understanding of employment information, looking for their own match points; quasi: accurate delivery of job information.
2、 Fudge: the new coronavirus is not produced in a laboratory environment
Anthony Fauci, director of the National Institute of allergy and infectious diseases, said recently that the latest research on the virus genome showed that the new coronavirus was transmitted from animals to humans, rather than produced or strengthened in the laboratory environment.
Recently, the epidemic in some European countries showed signs of slowing down. In some countries, the number of intensive care cases has decreased day by day, and the shortage of epidemic prevention materials has been alleviated. As of 18:00 local time on the 19th, Italian intensive care cases fell for 16 consecutive days. In France, the number of intensive care patients decreased and the shortage of masks eased. The prime minister said Spain had passed the most difficult time.
On the evening of the 19th local time, Czech President Zeman refuted the "conspiracy theory" of the origin of the new coronavirus and the claim against China in an interview with local media. He said that the story of conspiracy theory is laughable and sad.
Tan Desai, director general of who, said at the G20 health ministers' video conference Tuesday that some G20 countries are planning to reduce social restrictions, but they must do so in stages.
Tan Desai said that lifting the blockade does not mean the end of the epidemic, but the beginning of the next phase. It is important to educate the people and involve them in the prevention and rapid response to any recurrent epidemic, to ensure the ability to detect, detect, isolate and care for every case and track contacts, as well as the ability of the health system to receive any increased cases.
3、 Zhang Wenhong: there is a blind area in the health code. The best way to screen asymptomatic patients is nucleic acid detection
According to CCTV news on April 19, Zhang Wenhong said in an interview: for ordinary people, it may be necessary to learn to get used to the normalization of the epidemic while working and fighting the epidemic.
In the past week, several provinces, regions and cities have proposed nucleic acid testing requirements for personnel from high-risk areas. One of the important reasons is that Guangdong, Gansu and other places continue to have healthy green code of Hubei input asymptomatic infection and confirmed patients.
"The health code can only tell you that they have done some preliminary screening. In fact, there is no way to screen asymptomatic infections. So this can't be said to be a vulnerability of health code, just that it has a blind spot of screening. " Zhang Wenhong said that I am in favor of health code, because health code can cover most cases.
What to do if a small number of asymptomatic infections are missed? We need to set up some other mechanisms. Now the best technical means to screen asymptomatic virus carriers is nucleic acid detection. Collection of nasopharynx swabs and oropharynx swabs are two commonly used nucleic acid detection methods.
Zhang Wenhong said that the virus can't be seen or touched. Now the only thing that can be detected is the gene of the virus. A scratch in the mouth, a scratch in the nose, you can test the virus gene in a machine, as long as there are positive ones. So nucleic acid detection is very important for screening asymptomatic infection. The reason why three times of nucleic acid detection was not found was that there was a certain false negative probability in nucleic acid detection.
Zhang Wenhong said: a nucleic acid test, false negative rate should be 30%, false negative rate with what? Whether the sampling is done to get the bit, and how sensitive the detection is. But if we do it again, we can increase the sensitivity and reduce the false negative rate to 10%, so this is a very low probability event. There are loopholes through rigorous screening, and if we want to prevent them again, we need to continue to strengthen defense.
It has been reported that two doctors in Wuhan turned black after being rescued by ECMO. Experts explained that this may be due to the dark pigmentation and the dark skin of the whole body caused by the liver damage of severe patients. It may recover gradually after the liver function is repaired.
