After the global outbreak of the new crown pneumonia epidemic, the research on specific drugs has been slow, and the vaccine development process has taken a long time. The medical community has not yet effective prevention and treatment methods.Plasma therapy, this method has been proven and widely used in China. Not only in China, the American Journal of Pathology also published news about the safety and effectiveness of this therapy.
The principle of plasma therapy is to use the specific antibodies against the 2019-nCov in the plasma of recovered patients to quickly identify and capture the virus, and activate the complement system in the body to clear the virus.However, in the "Diagnosis and Treatment Plan for Pneumonia Caused by COVID-19 Infection", the Chinese Health Commission also clearly limits the clinical application of plasma therapy to "severe and critically ill patients."
Wu Yuzhang, director of the Department of Immunology of the Basic Medical College of the Army Military Medical University, emphasized that "plasma therapy" has a therapeutic effect on some critically ill patients, and does not mean that it can be used for prevention of healthy people, just like we cannot use antivenom to prevent snake bites.The most important thing for healthy people is to take protective measures to block the transmission route.
What are the protective measures to block the route of transmission?
1. Keep wearing a mask
The epidemic in China has been brought under control, but the notice issued by the local government should be followed for whether to wear masks. For example, where new confirmed cases of COVID-19 are found, it is recommended that everyone wear disposable masks.
However, as the United States has many continents, there is a higher risk of infection. It is recommended that people use disposable medical surgical masks and wear N95/KN95 masks when necessary.
2. Wash your hands frequently and keep your hands clean
Thousands of items are exposed to hands every day, among which door handles and
elevator buttons are highly contaminated article.Washing with soap or alcohol-containing hand sanitizer can achieve the purpose of cleaning, but before washing our hands, we should not touch our eyes, mouth and nose with our hands.
3. Maintain social distancing
Because one of the ways of transmission of the virus is droplet transmission, we try to keep a distance of 6 feet when we talk to others. This is for the sake of others and for our own health. In areas where the risk of infection is particularly high, special attention is needed.
