Since 2019, the new coronavirus has appeared in people's lives. In more than three years, the new coronavirus has undergone great changes; now, the new coronavirus is still very contagious. Although our country has implemented a comprehensive liberalization policy, we still need to pay attention to self-protection in peacetime, because a little carelessness may lead to new coronavirus infection.
Many experts say that there will be a second peak of infection of the new coronavirus during the Spring Festival. However, the end of the Spring Festival has arrived, and we still have not seen people around us with positive symptoms. Therefore, many people think that the current new coronavirus cannot be transmitted.
Therefore, we can see many people without masks on the street. These people think that the infection of the new coronavirus has become a fixed trend, and people who have been infected will not be infected again. But in fact, this idea is wrong; even after the epidemic, people are still at risk of being infected with the new coronavirus, so they must pay attention to self-protection in normal times and do not take it seriously.
The mutation process of the new coronavirus
So far, the new coronavirus has experienced alpha virus, beta virus, gamma virus, delta virus and Omicron .
The new coronavirus has evolved five times since its birth. The first evolution was in the United Kingdom, where it evolved from the common virus into the alpha virus; the second evolution occurred in South Africa, where the beta virus appeared; the third time was in Brazil, where the gamma virus was officially born; the fourth time was in India, where the most deadly delta virus appeared; and the fifth time was in South Africa, where the most contagious virus and the real "king of strains" Omicron virus was born.
The most widely spread virus in the world is the Omikron virus. Although the toxicity of the Omikron virus is not very strong and is not even comparable to previous viruses, the biggest "advantage" of the Omikron virus is its transmissibility.
Omicron is not only extremely mysterious, but also has a very long incubation period. Coupled with its asymptomatic infection characteristics, the detection of Omicron virus has become very difficult; maybe the COVID-19 test yesterday was negative, but today it turns out to be positive .
Omicron's powerful "invisibility" and contagiousness earned it the title of "Poison King". Omicron is more likely to cause reinfection than delta and previous variants. In addition, repeated infections still carry a certain risk of severe illness and can be transmitted to high-risk groups such as the elderly at home and those with underlying diseases. The
virus "cannot be transmitted"? Expert: The infection rate of the new coronavirus conforms to the law of virus transmission
htmlOn November 25, The official website of the China Centers for Disease Control and Prevention released the epidemic information of the new coronavirus infection nationwide,Nucleic acid detection results In terms of results, since December 9, 2022, the number of positive nucleic acid tests in each province and the positivity rate of the reported population have shown a trend of first increasing and then decreasing. The number of positive people peaked on December 22 (6.94 million) and then gradually declined, reaching a minimum of 15,000 on January 23, 2023; 5.5%.
Trends in the positive number and positivity rate of new coronavirus antigen tests in the national reporting population; on January 27, the director of the Institute of Critical Care and Critical Care Research at Shanghai University of Traditional Chinese Medicine said: “The spread of the new coronavirus is gradually weakening, not because of major changes in the epidemic, but because society maintains a certain low level of transmission. immune barrier has been consolidated, and the vast majority of people have been infected, forming herd immunity ”
The epidemic develops cyclically, from peak to trough, and then from trough to peak, which is in line with the law of virus development. For example, the United States and Japan have experienced several peaks since the COVID-19 epidemic.
html After the implementation of Article 120, nearly 80% of the people in the country have been infected with the new coronavirus, showing a "small peak" of transmission. Although it will not appear in the short term, there will still be a peak. This does not mean that the new coronavirus will disappear! Under the current circumstances, personal protection is still necessary.
What are the sequelae that will occur after being infected with new coronavirus ?
. It will leave some sequelae for respiratory system
The respiratory system is the main damage target of the new coronavirus, especially in the early stage of infection with the new coronavirus, the virus mainly causes damage to the respiratory tract, such as damage to the upper respiratory tract mucosa, causing patients to cough, increase sputum, etc.
However, many people are in a mild state after being infected with the new coronavirus. Therefore, the symptoms are tolerable and will not cause hypoxia and difficulty breathing.
However, some patients may gradually recover from mild symptoms after being infected with the new coronavirus. When the condition develops into severe disease, the patient's lungs will be more seriously affected and the patient will develop severe illness.
Although some patients developed severe pneumonia and were rescued after active treatment, the sequelae left by pneumonia cannot be ignored! For example, pulmonary fibrosis can cause atelectasis, hypoxemia, etc. In short, the adverse effects of the new coronavirus on the respiratory system cannot be ignored.
. It will have a certain impact on the nervous system
Some patients also feel slight headaches for a long time after being infected with the new coronavirus. In fact, this is also a sequelae left by the new coronavirus.
The main reason for this is that the new coronavirus will cause certain damage to the nerves, and the nerves can be repaired by the body in a short period of time and eventually return to normal state.
However, if the patient has experienced severe infection, the nerves in certain parts may be irreversibly damaged; at this time, the patient will not only have headaches, but also symptoms such as nerve conduction disorders.
Therefore, for such sequelae, when the body cannot repair itself, drug-assisted treatment is needed to hope for recovery; especially the elderly and children, repeated episodes of neurological sequelae should be paid more attention to, and early treatment is expected to better restore neurological function.
. It will have a certain impact on the taste and reproductive system
There are also a few patients who will feel no appetite for anything in a short period of time after being infected with the new coronavirus. In fact, this is a typical loss of taste; loss of taste is a sequelae left after viral infection, but after a period of recovery, the patient's taste can gradually recover.
In addition, many men will feel that their reproductive system is affected in a short period of time after being infected with the new coronavirus, which may have a certain impact on people's "sex life" quality.
However, don’t be too nervous, because this kind of sequelae will not last forever, and will eventually return to normal after a period of recovery; therefore, you don’t have to worry too much about hypogeusia and reproductive system sequelae.
extension: How to take care of yourself after being infected with COVID-19 to prevent sequelae?
After being infected with the new coronavirus, you must first do a good job in isolation, and during the treatment period, you must exercise your respiratory function and physical fitness through daily care to avoid sequelae.
In addition, it is recommended that patients do more breathing exercises, such as going up and down stairs, skipping rope, or I can adjust the body and mind through exhalation and inhalation, so as to achieve the effect of deep gas exchange.
In addition, COVID-19 patients can also perform resistance breathing training by blowing balloons or whistling, which can also avoid sequelae to the lungs.
You can usually do more aerobic exercises such as squatting, chest expansion, and climbing stairs to improve your physical condition and reduce the chance of sequelae after recovery; in addition to physical sequelae, some patients may also develop psychological sequelae, such as depression and anxiety.
Therefore, it is recommended that new coronavirus pneumonia patients adjust their mentality, communicate more with others, educate themselves, and avoid falling into a state of panic.
If long-term depression, anxiety and other emotions cannot be relieved, or post-traumatic stress disorder has developed, it is recommended that the patient go to the hospital's psychology department for professional psychological treatment in time to prevent depression, anxiety and other mental diseases!
In addition, after being infected with the new coronavirus, you should wear a mask when going out and avoid touching public facilities, so as to prevent the virus in your body from infecting other healthy people and avoid cross-infection; in addition, you must pay attention to washing your hands after returning home.
Hands are the organs in the human body that come into contact with most objects. They are easily infected with other viruses. A little carelessness may lead to cross-infection of viruses, which will have an adverse impact on human health!
