There was a time when most people might have turned pale at the mention of masculinity, but now it is commonplace to see people with masculinity everywhere on the street. Currently, 99% of infected people can fully recover within 7 to 10 days.

Once upon a time, most people may have turned pale when they heard the mention of positive and , but now it is commonplace that the streets are full of Xiaoyang people. Some people even said: "If you haven't met a 'Xiao Yang person' yet, please review your social skills." In fact, the current and strains are less pathogenic than previous new coronavirus strains. Currently 99% of infected people can fully recover within 7 to 10 days. Li Tong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital and a medical expert at Xiaotangshan Fangcang Hospital, once summarized an analysis of the symptoms of ordinary young and middle-aged patients infected with the new coronavirus from the first day to the seventh day after the onset of the disease, and the nucleic acid turned negative.

On the first day, you may feel a slight dryness and sore throat, and your body is sore and weak. Fever symptoms began to appear on the second day. Some young people may have a high fever of around 39 degrees and worsen throat discomfort. Day 3 is the day when symptoms are most severe for most people. Some people will have a high fever of over 39 degrees on this day, along with body aches, fatigue, and worsening sore throat. The peak temperature began to decrease from the 4th day. Many people's body temperature will be normal on this day, but they will still have symptoms of sore throat and itchy throat, and some people may have symptoms such as runny nose and cough.

By the fifth day, the body temperature of most people can return to normal, but symptoms such as nasal congestion, runny nose, sore throat, cough, and physical weakness still exist. On the 6th day, the body excretes necrotic cells through runny nose, cough, etc., so symptoms such as runny nose and cough may worsen on this day. All symptoms began to improve significantly on the 7th day, and the test results are likely to turn negative. Of course, everyone's body is different, so each person's specific symptoms and the time when symptoms appear may not exactly match this. These situations summarized by Dr. Li Tongzeng are for reference only.

Some people with good health may be fine in less than a week, and some may still not be fine after a week. The question that everyone is more concerned about now may be whether there will be any physical discomfort after recovery? Furthermore, we are worried that one infection will leave some permanent sequelae to our body? In fact, the issue of the sequelae of COVID-19 has been a concern for almost everyone in the past three years. At present, the vast majority of positive people will turn negative within a week or so, but after turning negative, they may still have symptoms such as fatigue, insomnia, memory loss, dizziness, headache, cough, and loss of smell or taste.

These symptoms may continue to exist for weeks, months or even longer after turning negative, but these symptoms cannot be called sequelae in a strict sense. The so-called "sequelae" in medicine refers to the irreversible and permanent dysfunction of human tissues and organs after the condition improves. In other words, sequelae refer to symptoms that permanently bother the patient, while symptoms that slowly disappear over time are not called sequelae. The symptoms mentioned above may indeed continue to exist for a period of time after the symptoms turn negative, but they will slowly disappear as time progresses and the health condition continues to improve.

Symptoms like this that will slowly disappear are not called sequelae. Academician Zhong Nanshan once explained the situation after human beings are infected with the new coronavirus: "Whether humans will get sick after being infected with the pathogen and the severity of the disease are the result of the combination of the number and virulence of the pathogen and the human body's immunity." The outcome of the struggle between virus and the human immune system will determine the severity of the symptoms. Likewise, whether there will be any sequelae after turning negative is also determined by the outcome of the struggle between the human immune system and the virus. Currently, about 99% of infected people have mild symptoms that can fully recover within 7 to 10 days.

At present, most of these mild patients have not found any sequelae after returning to normal. Although about 99% of infected people now have mild symptoms, there are still a few severe patients. Objectively speaking, these severe patients may still have some sequelae. In early November this year, the US Centers for Disease Control and Prevention reported that nearly 24 million adults in the United States were suffering from "long-term COVID-19" sequelae.Why do so many people in the United States suffer from "long-term COVID-19" sequelae, but many medical experts in my country say there are no obvious signs of sequelae?

This is mainly due to the differences in the epidemic situations between China and the United States: China's achievements in fighting the epidemic in the past three years are obvious to all. At present, the vast majority of infected people in our country have mild symptoms, so the possibility of sequelae is relatively low; in contrast, sequelae are relatively common in the United States. We need not over exaggerate the problem of so-called “coronavirus hangover”. Judging from the current domestic clinical experience, basically no cases of sequelae have been found. Of course, just because it hasn’t been discovered yet doesn’t mean it won’t be discovered in the future.

We should neither exaggerate the so-called "COVID-19 sequelae" nor ignore the possibility of sequelae. How can we avoid the sequelae of COVID-19 to the greatest extent? First of all, we must base ourselves on conquering the enemy without fighting. At present, we still need to avoid contracting the new coronavirus as much as possible. To take a step back, infection should be delayed and minimized as much as possible. Wear a mask when going out, maintain social distance, insist wash hands frequently, try to go to crowded places as little as possible, pay attention to personal hygiene... these are still what we need to pay attention to at the moment. As long as you are not infected by the new coronavirus, you don’t have to worry about any sequelae.

Enhancing immunity is also an important means to prevent the sequelae of COVID-19. Whether there will be sequelae depends largely on the outcome of the body's immune system's fight against the virus. Protecting our immunity is crucial in our fight against COVID-19. Staying up late, smoking, and drinking alcohol are all behaviors that may lead to weakened immunity. Proper exercise is helpful to enhance immunity, but excessive strenuous exercise can lead to a decrease in immunity. Especially when the weather is getting colder, you should pay attention to keeping warm and cold. If you catch a cold during this period, it will undoubtedly weaken the body's resistance .

There are two main "magic weapons" to protect our immunity: First, strict self-discipline and excessive gender control. If you can sleep well, don’t stay up late; if you can eat well, don’t overeat. The second magic weapon is the vaccination of vaccine . Although vaccination cannot prevent viral infection, it is still an effective way to prevent severe infection. Another thing is to maintain a good attitude. There is a certain relationship between human mood and body: a bad mood will weaken our immunity to a certain extent, while a good mood is more conducive to protecting our immunity. In addition, eating more high-protein foods such as eggs, beef, and dairy products during the epidemic will also help improve immunity.
