[Creative Cultivation Program] How to distinguish between "re-positivity" and "reinfection" with COVID-19?

Is it Yang? Is it Yang Kang? This is the most frequently asked question recently. Everyone will be Yang Kang in a few days, what should we ask next? Someone said, do I know what to ask about Wang Chongyang? There are actually two cases of Wang Chongyang, one is called Fuyang and the other is called secondary infection. This article specifically tells you the difference and connection between the two.

First of all, let’s talk about re-positivity. You may be on the ninth or tenth day of the onset of the disease, and you feel that there is nothing wrong with your body. You do an antigen test, poke the nasal mucosa with a cotton swab, and the result is negative. A negative result means that the cotton swab did not find any trace of the virus at this location on the nasal mucosa, that is, the N protein on its shell was not found. But does it mean that there is no virus in your body at all? Not necessarily. There may still be residual viruses in your trachea, bronchi and lungs. Later, when you go back and cough and expectorate, you may bring the virus to the nasal mucosa. The next day you say you want to take another test, and another test shows two bars. This is normal. It just means that the viruses have come here. That brings two questions: First, if it is re-positivity, do you need to take medicine? In essence,

Fuyang is just a different stage of the outbreak this time, the difference is whether the tail is here or here. It has just reached the end stage, so as long as there are no symptoms, there is no need to take medicine. But was it contagious in Fuyang? Of course it was. If the virus can run from inside to outside and breathe again, is it still contagious after it goes out? So wear a mask if you need to, isolate if you need to, to avoid spreading it to others. This is Fuyang.

What is the secondary infection? Secondary infection usually does not occur in the short term of the onset of the disease. It is often more likely to occur three months later. What is the situation? In addition to the bf7 or BA5.2 of Omicron, there are new strains, such as bq1 or xbb. The virus may not look the same as the original virus. After entering the body, the antibodies produced by our immune cells have come. We don’t know whether it is a bad guy or not. We don’t know it. There is no bad guy in our family, so don’t do it first. It escaped our immune monitoring. It is called secondary infection when it breaks out again. At this time, because it also carries n protein on its virus shell, you will see two bars when you do the antigen, but the principle of the two bars is different from the two bars of re-positive. It is not a strain. Is it contagious at this time? Of course, do you need to take medicine? The new strain has escaped the immune attack. It may also cause fever, headache, muscle aches, sputum and other symptoms. Of course, if there are symptoms, you need to take medicine. So there is a big difference between secondary infection and our re-positive. But in a special case, the two are connected and even equal. What is the situation? After your wave of Fuyang, you did not pay attention to maintenance and nutrition, which led to the resurgence of the virus in your body. Although there are two bars in this course of disease, its essence is equivalent to secondary infection. For example, after the virus enters your body, you experience symptoms such as fever and cough. Finally, our body produces antibodies and begins to eliminate the virus. Your symptoms are getting lighter and lighter. You are very happy that it is negative in two days and you are fine. You tell your family that you are healthy and you want to go out for running, swimming, playing football and climbing. As a result, you go out for strenuous exercise, overdraw your physical strength, and sweat a little without taking good care of yourself, so your immune system is suppressed, which is commonly known as low immunity. You were originally producing antibodies in batches to eliminate the virus, but as soon as your immunity is low, the production line is shut down, and no products come off the production line. Who will kill this virus? If there are only a few of these viruses left, it's fine. But if there are still 5% of them, even if there are no symptoms or it's not a big problem, but if no one cares about this virus, I go out on the street and see no police, and it starts to reproduce again, what is this called? It's essentially equivalent to secondary infection, it's a resurgence. So in the process of treating the new crown, we must be careful of this resurgence. If your husband's child's antigen is already negative, it means that there is no nasal mucosa at this location, and you want to go out for exercise, you say yes, but you are not allowed to run or jump today, just go out for a walk to get some air, and you can exercise tomorrow. But if your husband runs 10 kilometers every day, this time he is allowed to run 2 kilometers today. After coming back, wipe off the sweat and keep warm quickly, and then make some nutritious food for him to eat, so that his immune ability is always online, 3 kilometers on the third day, 4 kilometers on the fourth day, and restore his exercise ability little by little, isn't this safe and reliable?

As for secondary infection, you have to be careful and don't think it's special and long-winded. This secondary infection also needs to be prevented. Some people say that I didn't prevent Omicron this time with a mask, but there is nothing I can do. This time we were infected with Omicron, and its R0 value, which represents the transmission ability, reached a terrifying 16~18, which is too scary. However, the next virus, even the new coronavirus, may have an R0 value of 2 3 4, and wearing a mask can have a good blocking effect. So in order to prevent secondary infection, don't take off the mask easily, and don't go to places where people gather. These protective measures are equally effective in preventing secondary infection.
