Why did the cold disappear after the epidemic came?

Why did the cold disappear after the epidemic came?

actually, I feel quite strange when I see this question, because I don't know what the subject said!

I thought about it later, which should be related to these three points!

First, because of the sudden outbreak and strong infectivity, the prevention and control strategy of isolating the whole people at home and reducing going out was adopted, and fewer people came to the hospital because of common fever and cold.

Secondly, due to the sensitive period of COVID-19 epidemic, many people are worried that they will be forced to be isolated because of fever, and they will pay more attention to their health, so the number of patients with colds and fever has also decreased;

Third, in fact, the number of patients with colds and fever has indeed decreased compared with before. Why? Quite simply, the common cold, flu and so on are also caused by virus infection, and this is also a respiratory disease, which is the same as the main transmission route of novel coronavirus infection this time.

Therefore, while preventing and controlling the spread of Covid-19, we have actually blocked the transmission routes of common cold and some influenza viruses, so that there will be no common cold and flu, and some people will be infected and sick when they arrive.

However, it is wrong to say that the cold is gone, regardless of whether the epidemic occurs or not. It can only be said that there are fewer people with colds than before. Why can't a cold disappear like smallpox?

First of all, let's think about how smallpox was defeated by us. Did we find a special drug to kill it?

No, but the emergence of effective smallpox vaccine! From the perspective of infectious diseases, it protects susceptible people. We humans produce an antibody on us through smallpox vaccination, so that smallpox can't be a demon in us. As we all know, viruses can't survive independently and must be placed in the host. Therefore, the virus will die slowly.

Then, why can't a cold disappear by inoculating corresponding antibodies just like smallpox!

it's simple!

First, there are many reasons for colds, including bacterial and viral. Bacterial, we have a way, can be sterilized with antibiotics, but most colds are caused by virus infection, such as the most common rhinovirus, adenovirus and influenza virus.

So many viruses, if you want to make a vaccine, you have to make many kinds, and then it's no big deal, you can kill them!

The key point is that vaccines can't keep up with the speed of virus mutation, and not all vaccines can produce lifelong immunity after being injected into our bodies!

The most common flu, influenza, is now available, but we can all find that we still face the flu every winter and spring, and some people die of the flu every year, such as the United States. Since last September, the number of people who have died of the flu has been close to 2,!

Think about it, everyone has the flu vaccine, and there are special anti-influenza drugs like oseltamivir. Why do so many people still die of the flu in the United States?

In fact, the most important thing is the variation of influenza virus, and antiviral drugs are far behind antibacterial drugs. The main reason is that the research and development of antiviral drugs can't keep up with the rhythm of virus variation.

We have developed an antiviral drug for this influenza virus today, and a new influenza virus may appear in the next step.

We now have vaccines that can prevent several influenza viruses, but we still can't avoid influenza virus infection 1%, because it may mutate and have new kinds, which the current vaccines can't prevent.

Moreover, the current flu vaccine can only protect you from infection for about 1 months, and it is also the known flu viruses that are prevented. After that, the antibody in the body will drop, and it will lose its protective effect. You can still be infected if you don't take it next year!

The most important thing is that rhinovirus, adenovirus and influenza virus, which cause colds now, are all viruses born with us human beings. You don't know where they are, but they will always appear at a certain moment.

Therefore, it is possible that this epidemic will pass, but it is impossible to pass the cold, and it doesn't matter if it doesn't pass. After all, it is a self-limited disease, and most people can recover from the common cold in 7-1 days!

There is a correlation between epidemic situation and cold, but there is no causal relationship between them.

It's a typical attribution error to think that "the flu disappeared when the epidemic came" is exactly the same as the conclusion that "smoking can kill the virus", and the most classic case is "survivor bias".

therefore, we have to understand several points: just because you don't see someone catch a cold doesn't mean they really don't have it.

Before the epidemic, the cold was mainly external, and symptoms such as cough, sneezing and runny nose were obvious and easy to detect. However, after the outbreak, many people wore masks, even if they caught a cold, it was not easy to be found.

There is a bigger reason. Because the epidemic is coming, most people stay indoors, and the number of people you see is less than 9%. In terms of probability, there are even fewer people you see catching a cold.

But in fact, many people caught a cold during the epidemic. Not to mention, my wife had a cold, but she had a common cold and recovered in a few days. It's just that others don't know, and there's no need to advertise it widely. There is a correlation between epidemic situation and cold, but it is not a causal relationship.

When the epidemic comes, everyone stays at home. If it's just a common cold and the symptoms are not so serious, everyone is afraid to go to the hospital. The reason is simple: going to the hospital will increase the risk of cross-infection. Instead, it is safer to stay at home.

In other words, because of the epidemic, some common colds often choose to take medicine at home or "heal themselves", but this does not mean that the cold is gone.

from the time point of view, it is true that after the outbreak, people see fewer colds, but this is only a superficial phenomenon. Just because two things happen one after another does not mean that there is an inevitable causal relationship between them. The epidemic situation makes people pay more attention to physical protection, which may be a factor leading to the reduction of colds.

Of course, we should also see that because of this epidemic, we pay more attention to personal hygiene and physical health, and have developed good habits of washing hands frequently, opening windows for ventilation and wearing masks when going out.

It is precisely because of the formation of these good habits that the incidence of the common cold may actually be reduced objectively, and there is no need to see a doctor or take medicine. Although I have no data to support this conclusion, it is entirely possible.

Therefore, to sum up, the statement that "the cold disappeared after the epidemic came" in the title is not rigorous. There is a certain correlation between the two, but it is not a direct causal relationship, because the cold is not really less, but fewer people go to the hospital to see a doctor, and people pay more attention to self-health protection.

colds are always there.

At the time of the epidemic, the cold has become an underground worker.

do you dare to sneeze in crowded places?

do you dare to go to the hospital clinic and say that you have a fever?

do you dare to go to the drugstore to buy antipyretics and anti-inflammatory drugs?

if you dare, prepare for isolation!

you'll be caught on the way to the quarantine.

maybe in the process of suspected detection, you will be unexpectedly upgraded.

so, if you have a cold, you can only catch a cat.

Cats like cats.

you can't say that I caught a cold before until I get back to normal.

so, no one caught a cold.

no one dares to catch a cold.

This epidemic has focused everyone's attention on this infectious disease, so many people have the illusion that colds are rarely seen since novel coronavirus came.

However, this is not the case. I believe that many people caught a cold during the epidemic. novel coronavirus and the symptoms of a cold overlap, such as cough, fever, muscle aches, stuffy nose, runny nose, etc. Many people were quickly sent to the hospital for isolation when they had symptoms of fever. In order to effectively control the progress of the epidemic, many places would rather kill 3 thousand by mistake than let one go.

During the epidemic period, many people still caught a cold, but many people were afraid of being isolated. Although the state provided free medical care for such patients, many people were lucky, and isolation for 14 days would make them unacceptable, so they simply kept it a secret. Those who have a fever and headache should solve it themselves first, drink some antipyretics and painkillers, and then go to the hospital. Let me talk specifically about why there is a feeling that the epidemic has come and the cold has disappeared. 1. Travel is obviously restricted, which reduces the occurrence of colds:

In the past, it was impossible for people to stay at home honestly around the Spring Festival, but they would definitely go to the streets, have parties, and join in the fun and go to crowded places. We need to understand that colds are contagious. If a person has low immunity and often goes to crowded places, he is likely to catch a cold.

However, the emergence of this epidemic has greatly restricted our travel. We need to register and take temperature when going home. These inconveniences and the severity of the epidemic also make it possible for people not to go out. If you go out less, you are less likely to catch a cold. 2. When relatives stay together for a long time, many people will feel better:

Nowadays, people's life pressure is relatively high, and many people go out to work every year before they reach 15, just to earn more money to improve their family conditions and quality of life. However, with the arrival of this epidemic, many people have to postpone their work, so they will stay at home for a long time, which will prolong their contact with their loved ones. Those older people must be in a better mood and their natural immunity will be better, so they will be given the risk of infection.

Maybe you don't quite understand what I wrote. Although you are generally susceptible to novel coronavirus, its main high-risk population is 45-6 years old. If people of this age group are well controlled, the epidemic control will be obviously improved.

Imagine that if all our children go out to work and leave only their parents at home, they will definitely be in a bad mood for some time, so that their immunity will be reduced to a certain extent, and the time we spend with our parents will be greatly reduced with the acceleration of social rhythm. 3. Anyone who has a cold must try not to tell anyone:

During the epidemic period, we all stayed at home, and the chances of contact with others were obviously reduced. Everyone was worried about the epidemic, so who caught a cold and still spread it around? I'm sure I can hide it if I can, and I'll seek professional treatment if I can't hide it.

Because there are some similarities between symptoms and colds in novel coronavirus, fever should be reported, but for various reasons, many people still don't want to isolate them if they have fever.

Who said that after the outbreak of pneumonia in Covid-19, all the colds and fevers disappeared, and it happened correctly, but this cold and fever is different from usual:

First, if you have a cold and fever, you will definitely go to the hospital immediately, but now that there is an epidemic outside, many people choose to buy some cold medicine and fever medicine and eat it at home.

Secondly, I really have a cold and a fever, so I'm afraid to come out now, because the symptoms are too similar to those of pneumonia in Covid-19. If I come to an outsider, everyone will hide, and many of them will definitely call the police. So, I really have a cold and a fever, and people dare not go out.

Third, even the most common cough is held back. No matter what you cough, people around you, a few meters away from him, want to push him away.

Moreover, we say that in just a few days, the two major children's hospitals in Beijing have treated hundreds of children with fever, among which several cases were diagnosed with Covid-19 pneumonia and more than 2 cases were suspected.

Look, there are still many people who have colds and fever. Moreover, the turn of winter and spring and the beginning of spring are the seasons with frequent colds and fever. But because of the above three reasons, we can't see people with colds and fever, but we can't see them, not without them, so there are still many.

the last reason: everyone stays at home, and the probability of catching the flu is reduced a lot. There must be a cold, which is a "chronic disease" of our human beings. How can there be no cold germs because of Covid-19?

Therefore, people at home usually have a cold. If they have a slight fever, they won't feel very bad as long as they don't have a dry cough and weakness. Generally, it can be judged by experience that it is a common cold. Just take some cold medicine at home. Of course, if you want to relieve your symptoms after taking cold medicine, you will prove that your judgment is correct. If the symptoms are not relieved after taking cold medicine, you should go to the nearest hospital for examination. During the epidemic, if someone catches a cold, it will also cause their own panic. In fact, it is unnecessary.

During the epidemic period, many people caught a cold due to the increasing temperature difference between morning and evening during the Spring Festival. The symptoms of a cold will certainly have some mild cough, and some are accompanied by a low fever. Others may feel weak all over. This will make many people panic. Thinks he has COVID-19. Insist on going to the fever clinic for examination.

In fact, this is a bit too much, because catching a cold at ordinary times is very common, and it often happens when the weather changes. Why do you have to go to a fever clinic when there is an epidemic? Actually, if you ask me, I can't hide it! You think about it, you had nothing to do, and you had to go to the fever clinic because of a little cold. If you happen to meet a real virus carrier, you will go with them. What an injustice you have caused! Most smart people don't go to the hospital easily in this extraordinary period, so the cold seems to have disappeared.

indeed, smart people will judge their own physical condition. Of course, the main condition is that we judge the condition ourselves, and after taking relevant drugs, the symptoms should be alleviated, which should be clear. If the symptoms persist, even if you take cold medicine, you still have to go to the hospital. Because at this time, a professional doctor is still needed to make a diagnosis.

If the symptoms are relieved after taking the medicine, there is no need to worry too much. Combined with your travel history, it is easy to determine whether your discomfort is caused by a cold.

Therefore, we have the ability to judge whether we have a cold or not, so we don't need to go to the hospital. Then the feeling that gives people in the near future is naturally that there are no patients with colds!
