No most toxic only more toxic, the new crown virus of the same class of virus is still quite a lot?

!---- The global total of more than 16 million confirmed cases of new coronavirus pneumonia has become a major threat to public health in China and around the worldAt present, the new crown virus pneumonia has been included in the "Class B" infectious diseases stipulated in the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases, and according to the "Class A" infectious disease management; It was also made clear that the relevant testing should be carried out in a biosafety level II (BSL-2) or above laboratory, with the use of biosecurity level III (BSL-3) laboratory personal protection; Color photos from the Lancet new crown virus did not think, so powerful let people shiver shaking for more than half a year of "new crown virus", whether in the WHO risk (CLASS III), China's pathogenic microbial harm classification (class II), or China's infectious disease classification (Class B), these "three rankings", all belong to the "second danger level", thinking, then can not help but ask a sentence, and "new crown virus" and the same pathogens? This article takes you to understand that the world in addition to the "new crown virus", those who were once "wind and waves", blood and rain, sensational, awe of the natural "new crown virus" with the same class of pathogensHow are infectious diseases and biosecurity levels classified in our country? In order to prevent, control and eliminate the occurrence and epidemic of infectious diseases and ensure human health and public health, China enacted the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases as early as 1989, which is divided into "Class A", "Class B" and "Class C" according to the severity and statute of limitations, and has been revised and updated with the development of domestic related outbreaks for more than 20 yearsThe administrative department of public health under the State Council may decide to increase, reduce or adjust the types of infectious diseases of Class B and Class C according to the outbreak, epidemic situation and the degree of harm caused by infectious diseases and make them publicIt is worth noting that in the "Class B" infectious diseases, the new coronavirus infection of pneumonia, infectious atypical pneumonia, anthrax in the three infectious diseases are included in Class B, but can be directly adopted "Class A" infectious disease prevention, control measuresBiosecurity classification biosecurity is an important part of the country's overall biosecurityAccording to the WHO Laboratory Biosecurity Manual, China's Regulations on biosafety in pathogenic microbiology laboratories and the forthcoming Biological Safety Law of the People's Republic of China, pathogenic microorganisms can be divided into four categories according to pathogenicity and hazardA bit similar to the martial arts in the "hundred Xiaosheng" of the "weapons spectrum and figure list", according to the pathogen species is divided into four categories of viruses (four gate factions), according to the degree of harm (force value) will be various types of pathogens (each faction of the disciples) also divided into "one, two, three, four" category (see table below), the details of a classic spread of the "human infectious pathogenic microorganisms list." In order to strengthen the biosafety management of pathogenic microorganism laboratory and standardize the experimental activities of pathogenic microorganisms, china has further formulated the Directory of Pathogenic Microbes for Human Infection, which records in detail the hazard level of all types of pathogenic microorganisms and the level of safety protection required for experimentsThis article mainly introduces the "viral class" of pathogenic microorganisms in the "Human Borne Pathogen Microbiology List" of the same class as the new crown virusBiosecurity levels required for experiments on virus culture and animal infections are relatively higher than in the rest, such as nucleic acid testing of uncultivated materials that only need to be performed in Biosecurity Level II (BSL-2) laboratories, but also requirebiosafety level III (BSL-3) laboratory-level personal protection, but experiments involving virus culture and animal infections must be conducted at bSL-3 or above, and the level of personal protection must be increasedThe following are all the "second category" viruses, can be divided into several major sections: First, Bunia virus (17) in bunia virus, we may be relatively familiar with the "Hantan virus" that causes renal syndrome haemorrhagic fever, which is a sub-diastolic segment of the negative chain RNA virus, mainly divided into three: causing Hantan virus pulmonary syndrome (HPS), the other causes Hantan virus renal syndrome haemorrhage fever (HFRS) and other virusesHPS is mainly popular in the United States, China has not been found, but there is a possibility of occurrenceHFRS is the common renal syndrome haemorrhagic fever in China, the kidney is the early primary damage organ, the virus is the direct factor of kidney injuryIIThe bifa virus section (9 kinds) III, yellow virus department we common b encephalitis virus (JEV) belongs to the yellow virus departmentThe main symptoms are high fever, headache, vomiting, drowsiness, cramps, etcSeverely ill people can have peripheral height fever, convulsions, cerebral edema, respiratory or circulatory failure and die, some patients have sequelaeThe elimination of mosquito breeding grounds and the eradication of winter mosquitoes and new mosquito generation are the key to prevent ingestionPigs are the main intermediate host and infectious source of ethyl encephalovirus, before the epidemic season, pigs should be vaccinated, can effectively reduce the incidence of B-brainVaccination of the human body can improve the resistance to the infection of b-brain virus, the prevention of b-brain also has a good effect4Pox Virus Section V, impeachment virus section rabies virus (RV) belongs to the gangvirus familyThe shape is elastic, the nuclear shell is spiralsymmetrical, the surface has a coating, containing single-stranded RNAIt is a pathogen of zoonotic rabiesInfections are mainly through broken skin and mucous membranes, and can also be infected through the respiratory tract and digestive tractEffective treatment or vaccination soon after exposure to rabies can prevent symptoms and deathEmergency procedures include the immediate thorough flushing and cleaning of wounds with soap and water, detergents, polyoxoneio disinfectants or other solutions that kill rabies virusThe retrovirus HIV (HIV), the human immunodeficiency virus that causes acquired immunodeficiency syndrome (AIDS), was first detected in Central America in 1981HIV is integrated into the genome of host cells after infection, and current antiviral treatments do not eradicate the virusHIV is mainly transmitted through sexual transmission, blood transmission and mother-to-child transmissionHIV-infected people are the source of infection, but handshakes, hugs, kissing, swimming, mosquito bites, sharing cutlery, coughing or sneezing, daily contact, etcwill not spread7 Small RNA virus section, poliovirus can invade the central nervous system, damage the front corner of the spinal cord motor nerve cells, resulting in limb relaxation paralysis, causing poliomyelitis, because it is common in children, so also known as poliomyelitis There are no specific drugs for poliovirus infection, and control of the disease depends largely on the use of vaccines The disease spread widely and was reported in the country in 1955 Mr Gu Fangzhou (who died in 2019, aged 92) tested drugs with his son, who was just a full moon, successfully developed two live vaccines, liquid and sugar pills, and used a sugar pill to protect all children in China, saving hundreds of thousands of children from disability, many of whom still remember the taste of sugar pills as children This has devoted his life to polio prevention and control, and deserves the respect and praise of the whole country! 8 Positive sticky virus avian influenza is an infectious disease in poultry (poultry and wild poultry) caused by influenza A virus It can be characterized by mild respiratory symptoms, digestive symptoms, low mortality, or more severe systemic, hemorrhagic, septic symptoms, higher mortality According to the pathogenicity and toxicity, avian influenza can be divided into highly pathogenic, low pathogenic and non-pathogenic avian influenza Human infection with highly pathogenic avian influenza (represented by H5N1 and H7N7) has also been prevalent in China, the morbidity and mortality rate are very high, the harm is great, and included in the management of Class A infectious diseases, but with the understanding and treatment of diseases, according to the outbreak of infectious diseases, epidemic status and the degree of harm has been lifted Class A management, returned to Class B management IX In 2003, the World Health Organization announced that a variant of the coronavirus SARS was officially recognized as a pathogen causing severe acute respiratory syndrome (atypical pneumonia) Which is an infectious disease with acute, rapid transmission and high fatality rates, and most of the infected patients come into direct or indirect contact with the patient or live in the endemic zone The study reported that today's "new coronavirus" and the previous "SARS virus" is "parallel", belong to the coronary virus section, with SARS virus has 79.5% similarity, has also been included in the degree of harm classification of the second class of pathogenic microbial management Is there any new crown virus equivalent pathogen other than the virus? The above is described so much, are "second class of pathogenic microorganisms" classification of the "virus class", however, "second class" in addition to "virus class", there are "viruses," bacteria, line bacteria, chlamydia, mycoplasma, like transverse, spiral, fungi and other three categories, these pathogens are not small It may seem like a very distant dangerous pathogen, but it's actually very close to us For example, in the "bacteria" of the "second pathogenic microorganism", Yersinia pestis (commonly known as the plague bacteria) can lead to a natural epidemic of infectious diseases common to humans and animals - plague, is a statutory Class A infectious disease in China, highly contagious, high mortality rate, easy to cause a pandemic On July 3, 2020, Beijing time, the ituri provincial government of the Democratic Republic of the Congo (DRC) announced an outbreak of bubonic plague in the Djugu region of the province On July 5, a herdsman in the town of Urat Zhongqiweng in Bayangar City, Inner Mongolia, was confirmed as a case of bubonic plague Biosecurity alarm bells, awe of nature, building the future of mankind, working together to deal with the new crown virus and other types of outbreaks will be the future of global cooperation trend Although lucky to be born, do not take all things primates for their own, it is this arrogant self-esteem idea, it is hindering the progress of people, we are only a part of all things in heaven and earth, is the life of all things in one body, and will eventually melt in all things Source: Test Medicine Network, !-- content display ends -- !-- determine whether the login ends.
