Epidemic ** virus is an RNA virus, RNA and DNA are the genetic material of organisms, RNA is the "transporter" of DNA synthesis protein, and it belongs to the low-level genetic material. Because DNA and RNA are composed of countless genes (base pairs), and genes are easy to mutate (base pairs are replaced, lost, increased, etc., which will lead to genetic mutations, it can be said that the mutation of human genes occurs every day, but most of the mutations can not be maintained, but a few will be inherited or sick if they are preserved, such as tumors, genetic mutation is one of the main reasons), especially the RNA of the virus - the mechanism is very complex, I won't go into detail here, hehe- Because viruses are small and reproduce by exchanging RNA with the host, the base pairs (genes) in the RNA are susceptible to mutation due to the influence of the host RNA in the process of RNA exchange. After mutation, the type of virus will change, and the protein on its shell that causes the body's immunity will also change, causing the body's immunity to the original protein (also becoming antibodies) to fail, and the person will be infected with this new influenza virus again, and the flu will be affected.

Different antibodies and memory cells exist in the body for different periods of time, some can last for a lifetime (such as smallpox), and some are only a few days, and a cold is one of the shorter ones, usually a month. The mutagenic nature of cold viruses is also an important reason.
-
Taking cold infusion medicine is likely to lead to the production of antibodies, increase the course of the cold, and make the cold recur.
-
It leads to the production of antibodies, because it helps our physical health, and it also helps our body to develop, so I think it leads to the production of antibodies.
-
Yes, long-term infusions and taking medicines will cause the body to produce antibodies, so that the drug will not work and a new one will need to be replaced.
-
Because the production of antibodies requires certain conditions.
-
This is because our bodies do not allow it.
-
Because the conditions under which antibodies are produced are particularly stringent.
-
This is because our bodies are relatively special.
-
Because these bad viruses are also self-immune.
-
After all, we humans are relatively fragile creatures.
-
Because the human body is still very fragile, isn't it?
-
This is because viruses are always changing.
-
I think there are a lot of reasons.
-
Because the immune system is not yet able to produce antibodies.
-
First of all, because of the diversity of cold viruses; secondly, cold virus variability; The above two points lead to the fact that the cold virus can evade the first line of defense detection of the immune system every time, and finally the body's immune system must use its fighting ability to defeat the virus.
However, it is precisely because of the diversity of cold viruses that the body's immune system is trained all year round, which reduces the chance of serious illness in the human body.
-
Because the cold virus will mutate and be different every time, there will be no antibodies to get a cold. This is also the reason why people always keep catching colds throughout their lives. In general, it is not easy to catch a cold when you are in good physical condition.
Cold symptoms generally lessen or improve in about a week, and there are currently no specific anti-cold viral drugs, so not taking medicine after a cold will not have much effect. Taking medication is usually to reduce symptoms.
This is true of colds, but not all diseases can be resisted. If you are not feeling well, it is best to treat the symptoms of the disease as soon as possible, so as not to delay a minor illness into a major illness, so that it is too unwise not to treat it.
-
Of course, it is best to resist the past without taking medicine, and you will not catch colds often in the future.

Hello, the virus will not produce antibodies, especially repeated virus risk will weaken the resistance, we say that the virus is not like chickenpox, chickenpox will produce permanent immune antibodies, a person generally has chickenpox once in his life.
Guidance: I suggest that to prevent the virus, first of all, we must strengthen our resistance, pay more attention to rest, don't stay up late, drink more water, be in a good mood, breathe more fresh air, avoid staying up late to drink alcohol, avoid going to crowded places, and it is recommended that you can increase some common sense of dietary therapy to prevent colds, such as eating more bitter gourd, etc., I wish you good health.
-
Analysis: Hello, this is because the virus that causes a cold is not one, when you have antibodies to one cold virus, but you will not be resistant to another disease liquid poison. Quietly touch so that people will catch a cold many times. At the same time, the existence of cold antibodies is also relatively short.
Suggestions: You can improve your physical fitness through physical exercise and reasonable diet, which can reduce colds. I wish you health and happiness.
-
Because you are not immune to all the colds in the world.
-
To put it simply, because cold viruses are constantly mutating, and there are many viruses that can cause colds, the antibodies after a cold cannot resist the newly mutated viruses.
Pay attention to keeping warm, drink more boiled water, pay attention to keeping warm when the weather has cooled recently, and eat more vegetables. Strengthen physical activity.
I hope Chi Pi Zheng can help you!
