Introduction: In the long river of history, we humans have been affected by various plagues and the natural disasters of . From ancient times to the present, plagues have been an inevitable disaster for us humans to escape , and the sudden outbreak of the new coronavirus has completely disrupted our lives.
After the initial panic, our country successfully controlled the spread of the virus, and and experts also conducted corresponding research on the new coronavirus as soon as possible.
Since the outbreak of the new crown pneumonia epidemic , all countries have tried various epidemic prevention measures. and The vaccination rate of the new crown vaccine has been very high, but it still cannot bring everyone's life back to normal levels.
— SARS
It is undeniable that SARS virus did cause huge losses to us humans that year. That year, we all did not have the special drug for dealing with the SARS virus , let alone vaccinated.
Sas virus has the characteristics of high infectivity, high pathogenicity and high mortality.
Some patients will easily experience chest tightness and shortness of breath. This phenomenon will gradually worsen, and may even lead to respiratory failure , which will endanger life in severe cases.
The main transmission route of SARS virus is respiratory secretions and saliva If it comes into contact with respiratory secretions of SARS patients or close contact with with the patient, it will be easily infected.
We humans do not have natural immunity to SARS coronavirus, so humans are generally very susceptible to this problem.
Because of the lack of effective antiviral drugs, it mainly treats symptomatically in clinical practice . When necessary, it will also use a ventilator to assist breathing to help patients change the problem
——Serious Sars
The sequelae of SARS is caused by extremely dangerous RNA viruses, which can easily lead to fibrosis in the lungs, and the entire lung head will become as stiff as wood , causing the patient to be unable to breathe independently, and eventually die of respiratory failure.
Many experts and hospitals consider using large doses of hormones to save patients' lives and respiratory functions. Using large doses of glucocorticoid for impact treatment will leave sequelae in a few patients, and will easily lead to the phenomenon of femoral head necrosis .
Why did SARS suddenly disappear?
The main reason for the disappearance of SARS is that it successfully blocked the transmission pathway, and the active intervention and treatment of the disease by medical staff.
cut off the transmission pathway is the most effective form, and another direct treatment is also a very good method.
Although there is no specific drug for SARS, relying on its own resistance and other drug inhibition, the cure problem can be effectively achieved.
In fact, we humans cannot completely eliminate the SARS virus. The SARS era disappeared, which was more like the weather getting hotter and the virus itself died.
What is the difference between SARS virus and the new coronavirus?
Novel coronavirus pneumonia and SARS is that the new coronavirus pneumonia is caused by the infection of the new coronavirus SARS-CoV2, and SARS is caused by the infection of the SARS coronavirus SARS-CoV.
The genes of the novel coronavirus are very similar to the SARS virus and have many homology, but these are indeed two different viruses. The two viruses, , have certain differences in infection ability and mortality rate.
After SARS patients are infected with the virus, the general incubation period is 1 to 16 days, the disease is urgent, and the infection ability is strong;
After the infection of the novel coronavirus, the general incubation period is about 14 days, and the clinical manifestations are relatively mild at the onset, mainly mainly due to problems such as fever, fatigue, and dry cough.
Why is new crown difficult to eliminate?
One: The new coronavirus has a high variability
The variability of the new coronavirus is difficult for many people to figure out. Many people have found a lot of strain mutations before , such as α, β, delta, lamada, etc.
These mutated new coronavirus strains are not exactly the same in cleaning the body, so experts and doctors predict that the new coronavirus will continue to produce new variants in the future, and the virus strains are also constantly mutating, which brings great difficulties to the development of drugs and epidemics of seedlings.
The second: Eradication is very difficult
Medical experts compared "smallopsis" and " polio ", and the final result of found that the eradication of the new coronavirus is very difficult.
The immune protection effect of COVID-19 infection is currently unsure of how long it can last. Currently, there are cases of patients with secondary infection with , and these all indicate that the immune protection of COVID-19 may have a certain period of time.
The third: I cannot grasp the development situation
The new coronavirus has the characteristics of a pandemic and is still constantly mutating. Whether it is going to develop in a moderate direction or to develop in a more serious direction , it is unknown, so it cannot be completely eliminated.
The new crown has lasted for three years. When will it end?
The new coronavirus has been around for about three years now, and the epidemic has also allowed people all over the world to live in dire straits.
According to relevant incomplete statistics, the number of new coronary pneumonia caused at least 3.3 million deaths last year, and the number of confirmed cases exceeded 270 million.
COVID-19 is an RNA virus. The mutation rate of this virus is very high, so it is easy to have a large number of quasi-species mixed together.
and WHO also stated that when all countries and regions around the world give up holidays, ensure the use of the new crown pneumonia vaccine, and take corresponding prevention and control measures , the new crown epidemic is expected to end around 2023.
Can the new crown herd immunity barrier be established?
Vaccination with new coronavirus vaccine can help build a herd immunity barrier, which is also an important measure to effectively block the spread of the new coronavirus , and is a very convenient and effective means to protect the health of the whole people.
I hope everyone can get the COVID-19 vaccine and actively cooperate and take the initiative to do vaccination. Let us work together to establish an immune barrier and restore our work, study and life to the right track.
Experts from my country's Health Commission once suggested that if the epidemic is over, we must meet 4 conditions. The mutated ability of the virus is weakened, so that the virus's transmission ability will be weakened; the vaccine studied by experts can more effectively prevent the feeling of the new coronavirus Infection makes our antibodies the best weapon to effectively fight the new coronavirus;
Actually, these problems are very simple to say, but there are indeed some difficulties in implementing them. At present, the frequency of virus mutations is getting faster and faster, and the infectivity of the mutant strains that appear is also increasing.
And now although most people have received the COVID-19 vaccine, some people still cannot get vaccinated for individual reasons.
