After the release of the 20 articles on optimizing epidemic prevention and control, many over-the-counter cold medicines, including Lianhua Qingwen capsule, have become the target drugs that the public hoarded. On November 17, the reporter of Beijing Business Daily found that on public platforms such as Xiaohongshu, some consumers gave a list of drug hoarding. "Shopping in pharmacies like shopping in supermarkets, and storing medicine like storing vegetables." Some users wrote this sentence on their personal social platform. There are ibuprofen and acetaminophen for relieving fever and pain on the list of stored medicines; Cephalosporin, amoxicillin and roxithromycin for anti inflammation; The cough syrup, Chuanbei loquat, Runhou tablet, Lianhua Qingwen, 999 Ganmaoling, and Huoxiang Zhengqi soft capsule have become the standard configuration. Influenced by drug hoarding, several cold drug concept stocks rose sharply. By the end of November 17, Yiling Pharmaceutical, the manufacturer of Lianhua Qingwen, had risen by the limit, closing at 43.63 yuan per share; China Resources Sanjiu, the manufacturer of 999 Ganmao Ling, rose 6.24% to close at 59.28 yuan/share; Sunflower Pharmaceutical, Jichuan Pharmaceutical, Guizhou Sanli and Guizhou Bailing all rose to varying degrees. Drug hoarding also led to a shortage in the market. "There are still dozens of boxes left. Please come quickly. There is no guarantee that they will be available in three hours." The owner of a drugstore in Haidian District told the Beijing Business Daily that consumers had been snapping up Lianhua Qingwen for three days. Yesterday, 500 boxes were sold one day. The staff of a Guoda pharmacy in Chaoyang District said that there were two boxes of Lianhua Qingwen left in the store yesterday, but they were sold out today. "The headquarters will distribute the goods tomorrow morning," the staff member further said. Ibuprofen, Lianhua Qingwen and other drugs belong to the "four categories", namely antipyretics, cough medicines, antibiotics and antiviral drugs. Consumers need to register their name, address, ID number and contact information when purchasing. A staff member of Baikang Pharmacy in Chaoyang District pointed to the three pages of the registration book in his hand and told the Beijing Business Daily reporter, "This is all about hoarding drugs these two days.". In addition to some consumers hoarding drugs, some consumers remain calm. "The shelf life of both food and medicine is not long. Besides, the medicine has side effects, so we should be careful when using it. It is also a great waste if everyone hoards it out of date." Consumer Xiaosi told the reporter of Beijing Business Daily. Jin Dongyan, a professor of the School of Biomedical Sciences of the University of Hong Kong and an expert in virology, said in an interview with the Beijing Business Daily that the drug reserve related to accelerating the treatment of COVID-19 mentioned in the 20 articles on optimizing the prevention and control of the epidemic is a national reserve, hoping to reduce severe cases and deaths, rather than let people hoard drugs. At present, COVID-19 is a self limited and self-healing disease. The best specific drug is the neutralizing antibody produced by COVID-19 vaccination in the body. If the fever caused by COVID-19 is not treated with antipyretic drugs, it will subside 24 hours later, which is a sign of recovery. If there is a shortage of common cold medicine at home, it can be properly supplemented, but if you buy a lot, it will not be used in the future, and it will cause waste. "There is no need to hoard medicine at all", virologist Chang Rongshan told reporters of Beijing Business Daily that there are many causes of fever, which may be viral infection or bacterial infection
