What is the difference in prevention and control after adjustment?
——Social prevention and control are more concentrated in key places, institutions and groups of people
Chang Jile, deputy director of the National Bureau of Disease Control and Prevention, said that after the adjustment, there are four main differences in prevention and control:
First, in terms of discovering the source of infection, it is mainly through medical institution visits, residents' self-health monitoring, and testing of key populations to find infected people.
Second, in terms of the management of the source of infection, home health management is adopted for asymptomatic infections and mild cases.
Third, in terms of social prevention and control, social prevention and control measures are more concentrated in key places, key institutions, and key groups of people, cancel or reduce restrictions on the activities of institutions and personnel in other places, and minimize the impact on the normal production and life of the masses. Impact.
Fourth, in terms of border health and quarantine, after the implementation of "Class B and B Control", measures such as closed-loop transshipment and centralized isolation will no longer be implemented for inbound personnel.
Personnel coming to China fill out the health declaration card in accordance with customs requirements, and those who have declared normal and have no abnormalities in the routine quarantine at the customs port can directly enter the social area, and no preventive disinfection will be carried out on imported items, and imported cold chain foods will no longer be carried out. sampling.
What about medical reserves?
——The needs of different regions are different, and various measures are taken to expand medical resources
Jiao Yahui, director of the Department of Medical Affairs of the National Health Commission, pointed out that as the epidemic develops into different stages and the needs of different places are different, various measures should be taken to expand medical resources:
First of all, we need to expand the resources of fever clinics. Hospitals above the second level and all primary medical and health institutions must open fever clinics or fever clinics. They should be opened and set up as much as possible.
At the same time, the treatment process of fever clinics has been simplified, and the provision of medicines has been increased.
Second, implement hierarchical diagnosis and treatment.
In cities, prefecture-level cities are used as units to divide grid-based medical consortiums, while in rural areas, county-level medical consortiums are established to provide patients with hierarchical medical treatment services using a hierarchical diagnosis and treatment model.
At the same time, through Internet diagnosis and treatment services, online consultation and medication guidance are provided for fever patients, corresponding prescriptions are issued, and drug supply is increased through multiple channels.
Do you want to publish monitoring data?
- Announced once a month
Yin Wenwu, chief physician of the Department of Communication and Prevention of the China Center for Disease Control and Prevention, said that after the new crown virus infection was adjusted to "Class B and B", disease monitoring, reporting, and public announcements have been adjusted. The number of existing hospitalized cases and existing severe cases, including For the number of critically ill and cumulative death cases, the reports of previous close contacts are deleted, and the distinction between local cases and overseas imported cases is no longer made.
In terms of monitoring content, the network direct reporting of infectious diseases was mainly adjusted to comprehensive monitoring of case reports, nucleic acid and antigen detection, sentinel hospital monitoring, and monitoring of key populations and key places, especially the mutation of virus strains.
The frequency is dynamically adjusted according to the situation of the epidemic situation, and finally returned to Class B infectious diseases and announced once a month.
In terms of the announcement platform, the China Centers for Disease Control and Prevention will publish it regularly on the website of the Center.
In response to some netizens' opinion that after entering public places after "Class B and B Pipelines", Yin Wenwu emphasized that after the implementation of "Class B Pipelines and B Pipelines", the source of infection in the society is more uncertain, so it is even more important to do a good job. personal protection.
"When going to crowded places or taking public transportation, we still have to regulate the wearing of masks. For some key groups, such as the elderly with underlying diseases, children, pregnant women, etc., it is best to go out and gather less during the epidemic." Yin Wenwu Say.
What is the "white lung" rumored on the Internet? How's it going?
——White lung is severe lung inflammation, the actual proportion is very low
Jiao Yahui responded to the "white lung" that was hotly discussed on the Internet, saying that the so-called "white lung" that has emerged now has nothing to do with the original strain and vaccination, and the current prevailing strain is still the Omicron strain.
White lung is when there is inflammation or infection in the alveoli, and when there are exudate and inflammatory cells, the alveoli are filled with these exudate and inflammatory cells, and the rays cannot penetrate, and white areas appear on imaging.
She emphasized that not all lung inflammation is called white lung.
Generally speaking, when the inflammation of the lungs is severe and there is a lot of exudation, that is, the area of the white image area reaches 70% to 80%. At this stage, patients will experience hypoxemia or respiratory distress. Clinically, especially White lung may appear in elderly patients with serious underlying diseases, but the proportion is very low.
In addition, not only the new coronavirus, multiple pathogens can cause lung inflammation, such as respiratory syncytial virus, influenza virus, including some bacteria such as Legionella can cause lung inflammation.
"In terms of treatment, we now have a mature expert consensus and treatment plan, mainly prone position ventilation, and oxygen therapy, including non-invasive ventilator, invasive ventilator, and ECMO, which is called a life-saving artifact by netizens. .Strengthening the etiological treatment of the primary disease, a considerable part of white lung patients can get better." Jiao Yahui said.
