The outbreak of the new crown epidemic in 2020 poses a serious threat to the lives and safety of people around the world. The COVID-19 pandemic has deepened our understanding of national governance, international cooperation and changes in the international landscape.
Fighting the epidemic requires active cooperation among countries around the world, exchange mutual communication in vaccine research and development, medical supplies, prevention and control experience, etc., and jointly build human health community .
The current COVID-19 epidemic is capricious and the prevention and control situation is severe and complex. We must never relax. We must further improve our awareness of protection and do all protection work in an orderly manner. So in what way will the global COVID-19 pandemic end? Let’s analyze it together today.
In what way will the global COVID-19 epidemic end? Expert analysis: There may be 3 possible
From China's achievements in this epidemic, it can be seen that the source of infection is cut off, the transmission route is blocked, and public health intervention has successfully controlled the spread of the virus.
If the virus is allowed to spread in the population, and then almost everyone is infected, the body's immune system will produce an organism that can compete with the virus. Whether it is accepted or not, when the virus is out of control and the person continues to be infected, passive herd immunity will appear. To fully exert the inhibitory effect of the new coronavirus, we must reduce the chance of human-to-human transmission.
Through comprehensive vaccination and effective epidemic prevention, the new coronavirus has been completely eliminated. The main obstacle at present is that this virus is an RNA virus that mutates too quickly. At least from the moment, it seems that the development of a "broad-spectrum, effective prevention of infection" vaccine is far away.
The development of human technology is rapid. Perhaps this vaccine will appear on the scale of 5-10 years, or 10-20 years. If we agree that COVID-19 is similar to flu , then we should be mentally prepared. This disease may last for a long time in the human world and regularly attack humans, so vaccine development is very important.
The virulence of the new coronavirus may gradually weaken. Just like the influenza virus of
has become a seasonal disease like an influenza virus, but due to the improvement of human defense awareness, the guarantee of medical quality, lifestyle changes and the improvement of self-immunity, the lethality of the virus may not be so strong, and the chance of pneumonia or death is reduced.
Why can't the new coronavirus be eliminated?
According to the biological science author Zhang Tiankan, the virus will start to replicate after entering the cell. During the tens of thousands of replication, random errors will occur and mutations will occur. The genetic material of
coronavirus is the largest among RNA viruses. Although RNA fidelity is worse than DNA, it is more convenient for coronavirus mutation and makes people unable to defend against it.
Asymptomatic infected person causes the virus to spread implicitly, which is difficult to eliminate directly, and may even have immune escape. That is, antibodies produced by previous infections or antibodies produced after vaccination may gradually weaken the effect on the new coronavirus strain, making the new coronavirus more difficult to deal with.
The epidemic has been repeated. How to improve your immunity?
Immunity is the body's own ability to resist disease or defense. It can resist the invasion of viruses and foreign bodies on the outside, and can handle aging, damage, death, and degeneration cells on the inside, ensuring the normal operation of the human system.
Immunity is one of the most important indicators to measure whether a person is healthy, prone to illness, and after recovery.
During the epidemic, you should pay more attention to hygiene, wash your hands frequently, and eat food after it is cooked. Develop good living habits, quit smoking, limit alcohol and drink more water, and do not take supplements and health supplements randomly. Boiled water helps promote the body's metabolism and enhances the vitality of lactate dehydrogenase in various organs of the body, thereby achieving the effect of enhancing the body's immunity and disease resistance.
health products can easily cause additional burden on the human body and may also react chemically with other prescription drugs.
Under the epidemic, we should pay more attention to diet adjustments and need a balanced diet. In daily diet, try to ensure that you consume enough fresh fruits and vegetables every day; eat more high-quality foods with high protein protein content, such as milk, eggs, soy products, fish, shrimp, etc. For children, adequate intake of high-quality protein is an important factor in improving children's immunity.
Obtain all kinds of nutrients needed by the human body during the diet. In this way, maintaining a healthy state can naturally reduce the risk of infectious diseases. This is also a matter that needs to be paid attention to in the process of improving resistance.
High-quality sleep can promote the human body to produce more sleep factors. Sleep factors can promote the increase of white blood cells , and at the same time strengthen the liver's detoxification ability, so as to eliminate bacteria and viruses that invade the human body. Therefore, high-quality sleep can help improve human immunity.
ventilate the room in all directions during the day and refresh the air. At the same time, proper ventilation at night helps sleep and breathe fresh air.
WHO points out that when people develop negative emotions, more than 70% of people will digest these emotions by attacking their bodies' organs.
Long-term repeated nervousness and fear will cause changes in the body, such as increased secretion of tension hormones, causing accelerated heartbeat, increased blood pressure and blood sugar, vasoconstriction, insomnia, and decreased blood supply of internal organs and mucosa. Over time, it may cause lesions such as arrhythmia, hypertension, , diabetes , gastrointestinal inflammation and decreased immunity.
Regular exercise and increase exercise is the second greatest magic weapon to improve our body's immunity, and life lies in exercise. You must exercise regularly to extend your body's lifespan, improve immune function, and enhance physical fitness. You can run, play ball, climb and other leisure entertainment activities. You must have a good body and live and work better.
Many people lack exercise for a long time and do not have any exercise during the epidemic, which may have a negative impact when their resistance is weak. Therefore, if you want to promote physical health and effectively improve resistance, the most important thing is to exercise more.
Since the beginning of the pandemic, in order to curb the spread of the novel coronavirus, epidemiological and public health experts have been using mathematical models to predict future situations. But modeling infectious diseases is not easy.
Epidemiologists warn that models are not crystal balls that can predict the future, and even predict complex models that use machine learning together may not necessarily reveal when the pandemic will end and how many people will die.
