However, the first batch of infected people have just begun to recover, and the Internet has been full of discussions about "secondary infection". "The more infections, the worse the immunity" and "Repeated infections will lead to death" also began to appear.
What people are most worried about is the harm caused by repeated infections.
Some people quoted a research result published in the international academic journal Nature Medicine in June, 2022, and thought that compared with patients infected for the first time, the risk of death caused by repeated infection increased by 1.654, 38+0.7%, and the risk of hospitalization increased by 23.2%. However, the research object of this report is American veterans with an average age of 63, and whether it is applicable to ordinary people is controversial.
A study published in The Lancet-Regional Health (Europe) in September this year pointed out that 99. 17% of secondary infections were mild, and only a few were severe (0.78%) or critical (0.05%). The symptoms of reinfection are lighter than those of primary infection, and only 1.08% of secondary infected people need hospitalization.
However, groups cannot represent individuals, and individuals cannot represent groups. In order to understand the real situation after repeated infection with COVID-19, Tamen interviewed nine patients who were repeatedly infected with COVID-19, hoping to provide some reference for everyone from the aspects of infection symptoms, interval of repeated infection, coping and preventive measures.
1. What are the physical symptoms after the second infection with COVID-19?
At present, there is no clear definition of secondary infection in COVID-19.
According to the diagnostic criteria published by Taiwan Province Provincial Epidemic Command Center on September 3rd, 2022, COVID-19 was diagnosed with secondary infection after 14 days. According to the World Health Organization, the second infection in COVID-19 should be at least 90 days after the first infection. If the interval is less than 90 days, but evidence of different branches of infection is found, it is also judged as secondary infection.
This time, we interviewed 9 friends whose two infections were separated by 2-9 months. Their symptoms of infection are quite different. Some people have mild symptoms after the second infection, some people have obvious physical decline after repeated infection, some people have mild symptoms after the first infection, and the second infection is aggravated several times.
1. "The second symptom is lighter than the first one"
Qian Mian, female, 29 years old, was not vaccinated.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
Generally speaking, the symptoms of the second time are much milder. Last time it was like a big flu, this time it was like a common cold.
The first infection, fever for 3 days, the highest is about 38.7 degrees, sore throat and a little cough. I feel sick when I have a fever. I can't eat any food. I threw up after eating it Lying in bed for two or three days, it turned cloudy on the tenth day.
The second time, my parents infected me first and gave it to my daughter. The next day, I was also recruited. Mainly a sore throat. The next day, a low-grade fever began, with a maximum of 37.8 degrees. You can obviously feel the pain moving upward from the throat along the nasopharyngeal tube, and then there are symptoms of slight nasal congestion, headache and runny nose. This time it turned cloudy faster than last time, turned positive on Saturday and turned positive on Wednesday.
I think the antibody is still effective, because this time it was spread among family members, and it should be the same strain, but my parents were infected for the first time and the symptoms were much heavier. My husband and I are both infected for the second time, and the symptoms are mild, even sick. I can still take care of the baby from morning till night.
Jiang Mumu, a 39-year-old male, has received three doses of vaccine.
The first infection occurred in March 2022, and the second infection occurred in February 2022, with an interval of 9 months.
I was infected once in Korea in March this year. At that time, I had a fever for 4 days, reaching about 39.4 degrees. I feel headache and ache all over. After taking antipyretics, it didn't get better until the fifth day.
Later, when I went to China, foreign drivers often came to the company for work reasons. I think the second infection started with a foreign driver. One night, my colleagues and I ate at home. The next day, he felt sick. I had an antigen and found myself infected.
The second time, the symptoms were much lighter than the first time. I still have a fever and physical pain, but it's not as bad as the first time. I have a runny nose, like a cold.
Because I am not familiar with which medicine is better, I only took Lianhua Qingwen and 999 Ganmaoling. Later, I found it troublesome to take medicine, so I stopped taking it. A few days after the infection, I was still working and doing housework. On the fifth day, although the antigen was still positive, the body no longer hurt, just like when it was not sick.
Both infections were caused by Omicron, and the first time I felt more painful. But after this infection, I grew a lump on my body, probably because my immunity decreased during my illness and my body became inflamed, so I needed to go to the hospital to have it removed.
Quilt, 36 years old, from Shanghai, has been vaccinated with 1 vaccine.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
At the end of April and the beginning of May this year, I was infected once during the blockade in Shanghai. I felt a sore throat and a headache at that time. I have had a fever for several days, and I can't get down at about 37.4 degrees. On the seventh day, it turned cloudy.
After turning cloudy for the first time, the body easily feels tired. Later, when Shanghai was unsealed, I felt very tired and weak when I came home from work every day. I was lying in bed panting all the time, and I felt my body was evacuated. This state lasted for more than a month, and then it got better after taking multivitamins.
After the release of 65438+ in February, many people around me were positive. First, the colleague sitting next to me measured two bars, and the company asked us to work at home. Later my husband also measured two bars. I've always been fine myself, and I still think the antibody I was infected with for the first time is a little useful.
As a result, one day I felt a sore throat and sneezed several times. At four or five in the afternoon, my voice suddenly became hoarse. I feel terrible. Detected the antigen and found that the second one is very weak, which is estimated to be a scam.
The second infection was mild, with a low fever for two days, a little cough and yellow sputum, and the antigen turned negative on the fifth day. But I still work at home now, and I don't exercise much, so I don't feel weak before.
2. "Secondary infection will obviously reduce physical fitness."
Cheng Jiaqi, female, 32 years old, has received 3 injections.
The first infection occurred in February 20021year, and the second infection occurred in February 2022, with an interval of 3 months.
No sooner had I finished the third shot of vaccine than I got the second infection.
Before vaccination, I had a slight cough and sore throat, which worsened immediately after vaccination. Everyone around me was infected at that time. Although I wear a mask and take vitamins every day, it's useless. I thought that the antibody infected for the first time could last at least another six months, but I didn't expect to be "recruited" three months later.
Although the second infection turned negative within a week, I felt that my physical fitness dropped significantly this time:
I believe in Buddhism, and I used to do "big worship" (also called "kowtow") every day. When I was infected for the first time, although I was sleepy every day, I could still knock on three or four hundred "big services" every day. But the second time I coughed badly and had no strength at all.
The symptoms of the third infection were mild at first. I have no fever or cough. It turned cloudy in less than a week.
However, this year, my physical strength has been greatly reduced, and I will gasp when I move. Now it is confirmed that it is insufficient blood supply to the heart and myocardial ischemia. Chinese medicine says this is the sequela of COVID-19. Moreover, I think my memory has deteriorated a lot now, and I often forget what I promised others.
Xiao Hu, female, 2 1 year-old, has received 3 injections.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
During the incubation period of the first infection, my throat was always uncomfortable, and then I had a fever all night and found that the antigen was two bars.
The more serious symptom at that time was cough. I have been coughing intermittently for almost a month, especially in the first week. I wake up several times every night, I can't sleep all night, and occasionally I cough up phlegm after turning cloudy.
I have had two injections of Kexing, and I can get a booster injection six months after infection, so I went to zhifei on February 2 1 65438 to get the third injection, trying to enhance my immunity, but I had a fever the next night. I guess it was infected before, but it was still in the incubation period, and the symptoms came out after the fight.
The second infection burned me all night, and my cough was not as bad as the first one, just a headache and general weakness. I lay in bed for two days with a runny nose. Now I feel tired climbing stairs and it is difficult to breathe. I can't breathe because there is no elevator on the fifth floor of my house. I used to feel very relaxed when I climbed the fifth floor, and I wouldn't be so tired that I was panting. I feel very painful to breathe now.
Beckham, female, 28 years old, has received 2 injections.
The first infection occurred in March 2022, and the second infection occurred in February 2022, with an interval of 9 months.
The first infection was serious, with fever, soreness, fatigue, cough and various symptoms superimposed. I was in a state of fatigue and sore throat from March 26th to Tomb-Sweeping Day holiday. Fever for three days, cough 1 more than a month.
In the week of 65438+February, 1 1, the policy was released, and my friends and I went to make soup. Two days later, my friend became Yang. 14 began to have a sore throat, and it was not until 17 that yang weakness was detected, and 2 1 turned cloudy. The second time I was infected with Yang was quite short, but my cough has not been completely cured yet.
The second infection is mainly a symptom of respiratory tract. I swallowed a knife, coughed and got hoarse. I will have a slight headache at night, but I will sleep well. There is obvious fatigue after turning cloudy, such as going out to buy food. It used to be easy to walk over, and I felt very tired after the second infection.
From the point of symptoms, the second time was mild, but from the point of physical recovery after recovery, the second time was obviously weak.
3. "The symptoms of primary infection are mild, and the secondary infection is obviously aggravated."
My neighbor totoro, female, 24 years old, has received 3 injections.
The first infection occurred in June 20021year, and the second infection occurred in June 2022, with an interval of 2 months.
The first time was basically asymptomatic, with a slight cough and a dry throat. I have a fever for the second time. I have a sore throat, headache, backache, stuffy nose and a bad cough.
Mainly because I thought I was infected and would not be infected again, I went out to eat too many times with confidence, and the infection rate was greatly improved. My roommate doesn't go out to eat much, and he is always very negative.
Max, female, 24 years old, has received 3 injections.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
When I was first infected, I didn't have any symptoms. I have a slight sore throat and dizziness, like tonsillitis. It only hurt for a day or so.
But then I obviously felt that my memory was getting worse and worse. Sometimes I forget things at work. Sometimes I bring something, but I still look everywhere. I went to the physical examination some time ago and found an extra thyroid nodule. The doctor said it might be related to COVID-19 infection.
The symptoms of the second infection are much more serious than the last one. The first day, I had a high fever, a sore throat, a cough and a stuffy nose. I started to sleep at 9 o'clock in the evening, but I didn't sleep all night because of my headache. At that time, I thought I had nothing to do, so I took a shower and my symptoms got worse. The next day, I lost my strength. I had a high fever of 39 degrees and fainted all day. Repeated high fever lasted for 3 days before it subsided, and now it has just turned cloudy on the seventh day, with a cough and stuffy nose.
The second time I was infected, it was already very serious in the company. Both my parents are infected. Antibodies may still be effective within 6 months, but they will be useless after a long time.
Zhang, male, 26 years old, was not vaccinated.
The first infection occurred in July 2022, and the second infection occurred in June 5438+February 2022, with an interval of 5 months.
The first infection, uncomfortable for two or three days. At first, I had a sore throat. I was awakened by pain at five or six the next morning, and then I began to have a headache. I couldn't sleep all night. On the third day, my head stopped hurting and I coughed for two days. Basically, I'm fine.
The pain of the second time is at least three times that of the first time. The first night, I felt sick and couldn't sleep. I woke up in two or three hours, but I was not fully awake. I can't sleep well. My temperature was over 38 degrees and I stayed up until six o'clock in the morning. Repeated fevers alone tortured me for three or five days. I don't even want to pick up the cup with water at hand. It took a week to relieve. Now it's the tenth day, and occasionally I cough up phlegm.
This infection surprised me, because I didn't go out much in recent days, and I didn't have much contact with others. I don't understand how I got infected.
Second, how to treat COVID-19 after repeated infection?
Although there are many voices on the Internet, most of the interviewees said they don't want to be infected repeatedly. On the one hand, the process of infection is painful, on the other hand, people worry that repeated infection will damage immunity.
In this interview, the voices we heard the most were "Don't get infected if you can, because it's very uncomfortable" and "Do your own protection, but there is really no way to get infected in the end".
1. "Since you can't escape, you must be optimistic."
Jiang Mumu, a 39-year-old male, has received three doses of vaccine.
The first infection occurred in March 2022, and the second infection occurred in February 2022, with an interval of 9 months.
COVID-19 was very dangerous at first, but it's been a long time now. Just like a cold.
I think the sooner you get infected, the better. I didn't catch a cold for a long time after I was infected for the first time. I think it is because there are antibodies after infection, so it is not easy to get sick immediately.
It is said that it will be easy to get infected again after 3 ~ 6 months. I just recovered and have antibodies, so I don't care. But the main purpose is to be healthy, so I'd better be careful and try not to be infected again.
Quilt, 36 years old, from Shanghai, has been vaccinated with 1 vaccine.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
I was quite scared before this wave came. After all, there was one before, but when I really saw the second bar, I thought it was unexpected and reasonable. Since we can't escape, we have to face it optimistically.
I have read foreign studies, and repeated infections are lighter every time. I think this thing still has some antibodies. As far as my own personal experience is concerned, it's not that terrible. I should get another booster vaccine.
2. "Not so scary, not so cold."
Zhang, male, 26 years old, was not vaccinated.
The first infection occurred in July 2022, and the second infection occurred in June 5438+February 2022, with an interval of 5 months.
At the beginning of 2020, I didn't go out at home for more than 50 days, and I was scared by this thing. I feel horrible.
After the first infection, I felt less terrible. I'm pretty sure it was a bad cold and nothing happened.
After the second infection, my mind changed again. Not as horrible as I knew at first, nor as indifferent as I thought later. Still seriously ill, we need to pay attention to it and try not to get infected.
3. "I am still afraid of repeated infections."
Xiao Hu, female, received 3 injections after 00.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
I'm still afraid of repeated infections, because many people on the internet say that my health will get worse after being infected many times. I have done it for the second time now. If this situation continues, it will not be far from the third and fourth time.
Many foreign friends have experienced several infections. I will go to see their experience stickers and see how others are doing. Now I think I can stop being infected and take good care of myself, but I really can't help being infected.
Max, female, 24 years old, has received 3 injections.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
At first, I thought this kind of thing would never happen to me. I was very careful after the first infection, but I really didn't want it after the second infection. Because repeated infections still have a great impact on the body, every fever will affect various functions of the lungs and the body, so I am a little anxious.
Some people think that the sooner the better, it seems that it is not a good thing now, because the virus will mutate, and the strain infected each time may be different, but the antibody may only be six months. I am worried about the third infection because it is impossible to prevent.
Beckham, female, 28 years old, has received 2 injections.
The first infection occurred in March 2022, and the second infection occurred in February 2022, with an interval of 9 months.
I feel very sad after knowing the infection, and I am worried that there will be a second time, a third time and a fourth time. No one can tell the consequences of the COVID-19 incident. I don't know if I will encounter other problems, so I am worried.
Many people around me are very supportive of letting go. They think infection is inevitable, and even hope to get infected early, so they don't like masks. At that time, I had an idea whether the liberalization of the policy would have an impact on my future friends. For example, some people just don't like masks and just like to go to crowded places, so this person has a greater chance of carrying the virus. So should I reduce my contact with him? I have this question myself.
4. "I am mainly worried about the elderly."
Qian Mian, female, 29 years old, was not vaccinated.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
For people who are usually in good health, I have never felt that the disease itself is terrible. I'm worried about other things.
The first time I got infected, I was mainly worried about children and cats at home. What should I do if we go to quarantine? What about the cat? Worried about whether it will infect neighbors and whether neighbors will be afraid of us.
Now I am mainly worried about the elderly. There are many elderly people infected with this wave, and there are also many people in the hospital. My grandma and grandma are both over 80 years old, and they are both infected this time. I can only be glad that they don't have dangerous symptoms. If they are really serious enough to go to the hospital, their families must be very worried.
Three. What are the countermeasures/preventive measures in behavior?
After two infections, many people have taken a more cautious attitude towards the epidemic, saying that they can no longer take it lightly, and they should do a good job of protection and wear masks. In addition, some people insist on fitness habits to improve their body resistance, some people buy oximeters and oxygen generators for emergencies, and some people go to the hospital to take pictures to check whether the lungs are damaged.
In addition, people's understanding of the epidemic is that virus prevention should not disrupt the rhythm of normal life. As the interviewee @ Zhang said: "I was injured during normal walking, and the wound dressing has to move forward. I can't always revolve around this matter."
1. "Go to the hospital for examination"
Xiao Hu, female, received 3 injections after 00.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
I was worried that the infection might hurt my lungs, so I went to have a CT scan. The result was normal, so I was relieved. If you have a bad cough, you still have to go to the hospital for examination.
2. "Should protective measures be taken or will be taken?"
My neighbor totoro, female, 90 years old, has received 3 injections.
The first infection occurred in June 20021year, and the second infection occurred in June 2022, with an interval of 2 months.
Going out to eat now will be more cautious, and protective measures still need to be taken. Although everyone has been infected and has group immunity, they are still worried that they will be infected with new strains. After a loss, I'm not as arrogant as before.
Max, female, 24 years old, has received 3 injections.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
After the first infection, I felt that my physical fitness didn't keep up and went to the gym. The result still failed to resist the virus. I think we should keep healthy when we have the chance. When the virus comes, it depends on whether your immunity can be beaten, keep a good routine and exercise properly.
It's time to coexist with the virus. Everyone should protect himself. I don't think ordinary masks have any effect. You can basically wear N95.
3. Buy antipyretics, oximeters and oxygen generators.
Qian Mian, female, 29 years old, was not vaccinated.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
Our family has prepared some antipyretics and oximeters, so we can monitor our situation at home and know when to go to the hospital if there is any discomfort, so as not to be particularly anxious.
For ordinary people, what we can do is to plan ahead and live the life we should live. It is impossible for us not to go out and go to work because of this virus.
Zhang, male, 26 years old, was not vaccinated.
The first infection occurred in July 2022, and the second infection occurred in June 5438+February 2022, with an interval of 5 months.
After the second infection, because the symptoms were a little serious, I was worried that the elderly at home would be affected, so I bought an oxygen generator and an oximeter.
Illness is an inevitable part of life. Without this disease, there will be other diseases and we must live a normal life. While living a normal life, wear more masks, exercise more, prepare more medicines at home, and prepare some medical equipment for the elderly.
Beckham, female, 28 years old, has received 2 injections.
The first infection occurred in March 2022, and the second infection occurred in February 2022, with an interval of 9 months.
I really don't want to be infected again. You will still wear masks and disinfect your hands when you go to crowded places. This time it was my parents, grandparents were infected, because grandparents had oxygen machines at home. Now I let them take turns to take oxygen every day. I also bought them oxygen machines, but it will take a week to deliver them. At that time, I found that many stores were out of stock.
4. "Watch less social media and reduce anxiety"
Qian Mian, female, 29 years old, was not vaccinated.
The first infection occurred in April 2022, and the second infection occurred in June 5438+February 2022, with an interval of 8 months.
I have a feeling that if I often go to social media, I will find the epidemic particularly scary, because people with mild symptoms may not share these experiences online, and only those who are particularly uncomfortable will want to share them online.
I think it's better to spend less time on social media and create less anxiety for yourself at special times. If I see some strange rumors, I will still be anxious until I find that they are false. This is a kind of internal friction, so I choose to watch less social media and less mass news.
Fourth, write it at the end.
As of the date of publication (65438+February 29, 2022), the "Ten Articles of New China" has not been launched for one month, and most people in the country are still in the initial stage of infection.
Therefore, the samples we can interview who have experienced "secondary infection" are limited: most of them are young people who are active on social media, have no basic diseases, and are mild cases in COVID-19. Although it can't represent all possible situations of "secondary infection", I hope to provide you with some references other than macro data.
At present, people have a lot of unscientific understanding of secondary infection. The internet is full of all kinds of information, either sensationally fabricating rumors or downplaying the symptoms and injuries of secondary infection. We hope to remind everyone that secondary infection is not so terrible, but we should not take it lightly, based on the real experience of 9 cases of repeated infection in COVID-19.
In addition, we also want to express that there are many studies on secondary infection at present, but not all secondary infected people follow the "significant" research conclusion. For example, studies have shown that vaccination can effectively reduce the risk of secondary infection. More than half of the respondents have been vaccinated with 3 injections and are still infected with secondary infection.
In the case that the consequences of secondary infection are unknown, the only thing we can do is to consult all kinds of information extensively and make more screening, instead of believing it unilaterally or denying it completely. If it causes internal friction, it is better to watch less social media and mass news, just as the interviewee @ Qianmian said, to make your mind more peaceful, or as @ said in the interview, "it is safe when you come".
I hope I can help you!
