The fifth edition of the diagnosis and treatment plan was proposed for the first time, “asymptomatic infection may also become a source of infection”, so it is necessary for the people to be isolated at home for one week before returning to work.
On the afternoon of February 3, the National Health and Medical Commission issued the “Pneumonitis Diagnosis and Treatment Program for New Coronavirus Infection (Trial Fifth Edition)”. Compared with the previous version, this version has stronger guidance and operability, and focuses on optimizing the treatment of critically ill and critically ill patients. Compared with the fourth edition, the fifth edition has the following major updates:
In terms of epidemiological characteristics, it is first clear that “asymptomatic infection may also become a source of infection.” According to Lin Ling and Li Taisheng, infection physicians at Peking Union Medical College Hospital, this means that the infected person may also transmit the virus during the incubation period before symptoms appear, so it is necessary for the people to be isolated at home for one week before returning to work.
The second plan states that “transpiration through respiratory droplets and contact is the main route of transmission.” Ordinary people should pay attention to droplets and contact transmission, wear masks and wash their hands frequently when going to public places and taking public transportation.
For the description of susceptible people, retain “general susceptibility”, delete “the elderly and those with underlying diseases are more severely infected, and children and infants are also affected”. According to interpretation, this article emphasizes the general susceptibility of the population.
In terms of diagnostic criteria, the fifth edition changes “fever” to “fever and / or respiratory symptoms”. It is currently known that fever may not be the first symptom of some patients with neo-coronary pneumonia, and some patients have low body temperature, which needs to be combined with pulmonary imaging and nucleic acid screening for diagnosis.
In terms of treatment, the fifth edition proposes for the first time: “No effective antiviral treatment is currently confirmed.” Lin Ling and Li Taisheng interpreted that experts have recently unified this opinion, so it is effective for rumors of Shuanghuanglian, clinzhi (namely, lopinavir / ritonavir), and Remdesivir. It is still to be confirmed that people should not store or take medicine without authorization.
Furthermore, the fifth edition has revised a lot of content, such as changing the incubation period to “1-14 days, mostly 3-7 days”; emphasizing “ensure safety” when transferring suspected patients; emphasizing close contact with infected people In patients, even if common respiratory pathogens are detected positive, it is recommended to perform new coronavirus detection in a timely manner.
It is worth noting that in the afternoon of February 3, the National Health and Medical Commission also held a press conference. Regarding the use of drugs in front-line clinical treatment, Song Shuli, a spokesman for the National Health and Medical Commission, said that there are currently Kelizhi and traditional Chinese medicine treatments, and clinical trials are collecting clinical information data. There is also a recent drug called Redecive. Medical institutions are conducting clinical trials on the drug organization, as well as researching the safety and effectiveness of the drug.
