The National Health and Wellness Commission announced on the 26th that novel coronavirus was renamed novel coronavirus Infection. According to the announcement, with the approval of the State Council, the measures for the prevention and control of Class A infectious diseases stipulated in the Law of People's Republic of China (PRC) on the Prevention and Control of Infectious Diseases will be lifted from June 8, 2023. Novel coronavirus infection is no longer included in the management of quarantine infectious diseases stipulated in the Frontier Health and Quarantine Law of People's Republic of China (PRC).
On the same day, the Comprehensive Group of Joint Prevention and Control Mechanism of the State Council released the Overall Plan of "B and B Management" for novel coronavirus Infection. According to the plan, comprehensive evaluation of virus variation, epidemic situation and prevention and control basis in China shows that China has the basic conditions to adjust novel coronavirus infection from "Class A infection" to "Class B infection".
The difference between Class A and Class B infectious diseases lies in different diseases and different management methods.
1, different diseases:
Class A infectious diseases refer to cholera and plague, and Class B infectious diseases are divided into 27 kinds, including SARS, viral hepatitis, AIDS, measles, epidemic hemorrhagic fever, whooping cough, tuberculosis, bacterial and amebic dysentery, etc.
2. Different management methods:
Class A infectious diseases belong to strong infectious diseases that are subject to compulsory management, and they need to be reported immediately within two hours after being discovered, while Class B infectious diseases need to be strictly managed, requiring direct network reporting within six hours after being discovered in towns and within 0/2 hours in rural areas.
Although Class B infectious diseases are also infectious diseases, the mortality rate is not very high, and it will not lead to large-scale deaths and outbreaks compared with Class A infectious diseases. Therefore, Class B infectious diseases are relatively light compared with Class A infectious diseases. But they all need isolation treatment, and they should be thoroughly disinfected to prevent infection.
Cholera, a class infectious disease
Cholera is mainly caused by cholera enterotoxin 0 139 and Vibrio cholerae 0 1. It is caused by eating polluted water, polluted seafood, polluted grains and polluted fruits and vegetables. Cholera is more acute when it occurs, and usually there are symptoms such as diarrhea and vomiting.
Class A infectious disease plague
Mainly infectious diseases caused by Yersinia pestis, mainly prevalent in marmots, rodents or other rodents. It is because Yersinia pestis will multiply and replicate in the body after invading the skin, and cause various uncomfortable symptoms, such as chills, high fever and shortness of breath. Some patients may have symptoms such as decreased blood pressure, tachycardia and unconsciousness.
Infectious atypical pneumonia caused by Class B infectious diseases
Infectious atypical pneumonia generally refers to severe acute respiratory syndrome, which is an acute respiratory infectious disease caused by SARS coronavirus. The World Health Organization named it Severe Acute Respiratory Syndrome. The disease is a respiratory infectious disease, and the main mode of transmission is close droplet transmission and contact with respiratory secretions of patients. This disease broke out in our country in 2003, which caused everyone's panic. The clinical manifestation of the disease is fever as the first symptom, and the body temperature often exceeds 38℃, showing irregular or relaxed fever. The course of fever is more than 1-2 weeks, accompanied by headache, muscle aches, general weakness and diarrhea. 3-7 days after illness, there will be dry cough, less phlegm or bloodshot blood, which is easy to cause secondary infection during this period.
