Rumor identification: There is no preventive medicine for the new coronavirus. Rumor analysis: 1. The culprit of this pneumonia is a new coronavirus named “2019-nCoV”, and there are no confirmed effective anti-new coronavirus drugs. Although oseltamivir (trade name “Tamiflu”) and ribavirin (trade name “Viralin”) are antiviral drugs, the former is mainly used for the treatment and prevention of influenza caused by H5N1, H9N2 and other subtypes of influenza viruses. The latter is often used to prevent and treat parainfluenza, hepatitis A, B and C, measles, herpes simplex, and possibly anti-tumor effects. However, the effect of both on this new coronavirus has not been found. 2, “Tamiflu” and “Viralin” may also cause adverse reactions if taken by themselves, including diarrhea, nausea, vomiting, liver function damage. Special Note: At present, the new coronavirus pneumonia can be prevented and controlled, so the public mainly relies on daily protective measures to prevent the disease, such as washing hands regularly before and after meals; washing hands with soap or alcohol-based hand sanitizer after coughing or sneezing; avoiding crowded public places and wearing masks when going out; keeping windows open and the environment clean at home and workplace.
