(Fighting against New Coronary Pneumonia) Li Lanjuan's trans-oceanic "cloud" answers questions and sends anti-epidemic tips for overseas students abroad

　　China News Service, Hangzhou, April 18th (Reporter Zhang Yuhuan) On the evening of April 17, the “Sentimental Love Youxin Heart Disease Prevention Epidemic Prevention At This Time” live broadcast of the scientific epidemic prevention activity of Zhejiang Care Overseas Chinese and Overseas Students, Academician of the Chinese Academy of Engineering Li Lanjuan, a member of the expert group at the level, gave live broadcasts of epidemic prevention knowledge to Chinese citizens traveling to Spain, overseas Chinese and overseas students, and gave online answers to topics such as how to protect themselves and what to pay attention to after resuming production.

How to avoid the risk of infection

　　Chen Pengyu, an international student in Madrid, Spain, asked if there are low levels of vigilance against the epidemic in a shared living room (shared living room, kitchen, toilet, etc.) with a roommate, if there are some details or hygienic habits in the shared living, can you help you avoid it Potential infection risk around you?

　　"When renting together, don't move too much between people, and prepare certain disinfection measures in your room. Use time of public space as staggered as possible to avoid simultaneous use." Li Lanjuan replied.

Is it safe to order takeout and go shopping

　　Chen Pengyu asked, if the person who ordered take-out or door-to-door did not wear a mask or related protection, is it necessary to disinfect the received items?

　　Li Lanjuan believes that when it is impossible to judge whether the deliveryman is safe, keep distance from others when accepting takeaways and other items, and try to avoid face-to-face handover. "For example, you can ask the other party to put the item in the designated place and wait for someone to leave it before taking it. You can first remove the outer packaging and then take the item in, and wash your hands in time after handing over the item."

　　Wang Shengwei, an international student in Valencia, Spain, asked: When going to the supermarket to purchase, how do you deal with the shopping materials to ensure its safety? Can disposable masks be used repeatedly?

　　Li Lanjuan told international students that they must first wear a mask when going out shopping. The purchased items are usually safe after the outer packaging is removed. During the epidemic period, it is recommended not to drink cold food, and the food must be cooked and imported again. "In addition, disposable masks are not recommended for repeated use."

How to avoid cross infection after resuming labor

　　Li Xinyu, a Spanish overseas Chinese in Madrid, asked Li Lanjuan. After the Spanish company resumed work, what other suggestions would it have in addition to measuring body temperature, wearing a mask, washing hands, using disinfectant and keeping a distance in preventing cross infection? The newly diagnosed and cured Spanish pneumonia patients were discharged and theoretically had antibodies in their bodies. But can't they be considered 100% safe and not contagious?

　　Li Lanjuan said that because there are still new cases in Spain, it is necessary to prevent the rebound of the epidemic after resuming work. Including the need to strengthen the detection of suspected patients and people in close contact, find out infectious asymptomatic patients and patients, isolate them, and prevent the spread of disease.

　　"At the same time, we must strengthen the health screening of re-workers. For those who have been discharged from hospital after two weeks of isolation, those who produce antibodies (IGG positive and IGM negative) can safely resume work," Li Lanjuan said.

Whether it is necessary for enterprises to purchase reagents for testing

　　Xue Ying, a representative of Spanish Chinese-funded enterprises, raised questions about the accuracy of rapid testing reagents and asked Li Lanjuan, "Do you recommend that Chinese-funded enterprises order some rapid testing reagents from China to prepare for suspected employees' initial self-test?"

　　Li Lanjuan said that the current "gold standard" for new coronavirus detection is still nucleic acid, and antibody detection is a good complement to nucleic acid detection technology. "In China, it is generally recommended to add nucleic acid detection and antibody detection. The accuracy of rapid detection reagents is relatively high, and some can reach more than 95%. However, in addition to the accuracy of the reagents, the test results are also related to the quality of the samples collected. , Factors such as the patient ’s course of disease, etc., require comprehensive judgment. "

　　Li Lanjuan pointed out that each country has its own medical regulations. Chinese-funded enterprises order reagents for employees to use as reference for testing, but not against it; but the testing process and results require professional doctors to guide and explain, and whether the testing results can be adopted by local medical institutions also depends on local management regulations.

　　It is reported that the live broadcast event was sponsored by the Chinese Embassy in Spain, the Joint Working Group of Chinese Citizens from Zhejiang Province, China, and Zhejiang Province. (Finish)
