This time the new coronavirus, really give people the feeling that its particularly cunning, the ability to spread very strong not to mention, induced symptoms are relatively complex, according to Zhong Nanshan academician team expert group in medRxiv published the content of the paper to see, only 43.1% of the patients in the hospital at the time of admission with fever, 87.9% of the hospitalization during the emergence of fever, so some people questioned the body temperature screening is still meaningful?

In fact, screening temperatures is not only meaningful, it's significant!

We can putThis fight against the epidemic caused by the spread of a new coronavirus is treated as a battle!And our enemy is an almost invisible, very tiny virus that we don't really see, so how can we detect it and defeat it?

Taking a temperature is the equivalent of being at the forefront of a battle! And it doesn't require mobilizing large numbers of professionals.

This virus is so small that we cannot see it, but when it invades the human body, it produces a variety of symptoms, which gives us the opportunity to discover it and find it.thread (of a story)。

Although, at this point in time, just under 50% of the population may experience symptoms of fever in the early stages, it is possible to do so by taking a temperature, which is very simple, easy to do, and anyone can learn to do itA preliminary screening. Especially in public places where many people come and go, such as supermarkets and office buildings, if we find people with elevated body temperatures, we can promptly tell them to go to the hospital for relevant examinations to clarify whether it is a new type of pneumonia.

Although not all of these elevated temperatures are necessarily the result of a new type of coronary pneumonia, one can think about theIf large numbers of people with elevated temperatures are placed in public places without screeningWhat are the consequences of having a patient with a new virus, pneumonia? I believe those who have been following the news reports are more aware of it.

Once the febrile patient has been screened, it's time to call out the professionals!

Once these febrile people have been screened, I am afraid that the presence of novel coronavirus infection in patients can no longer be determined by simple temperature measurement, and at this point a professional must step in!

ifIf our friends who take temperatures are militia, the medical professionals are soldiers.！

The healthcare provider will first ask the patient in detail if they have a 4th or confirmed case, or if they have been in contact with people in the infected area, do aepidemiologicalof screening. This is followed by giving the patient act and blood tests., these checks are the equivalent of a weapon in the hands of a warrior!

These tests are used to clarify the presence of specific ct imaging findings in these febrile populations, such asFrosted glass shadows, nodular shadows, whether there is a relatively speaking specific blood manifestation.
If a febrile patient hasEpidemiologic history of exposureinsymptoms、ct and other imaging findings和blood testIf two of the three are positive, he or she will be listed as a suspected case!

If there is no history of epidemiologic exposure, ifsymptoms、ct and other imaging findings和blood testThose who are positive for three of the three will also be listed as suspected cases. (There is a difference between the suspected diagnosis in Hubei Province, where the imaging features of pneumonia can be classified as a suspected case!)

This puts us within striking distance of catching the new coronavirus! So how do we make a definitive diagnosis? We have the killer!

According to the 5th edition of the Guidelines for the Treatment of Aberrant Coronavirus Pneumonia, suspected cases require real-time fluorescent RT-PCR of respiratory or blood specimens for detection of the novel viral nucleic acid and respiratory or blood specimens for viral gene sequencing! A positive test for either of these two tests confirms the diagnosis of a patient with aberrant coronavirus pneumonia.

It is also mentioned in the current paper published by the team of academicians from Nakanoyama, that if we take theA combination of ct examination, nucleic acid kits and clinical signs ofThe accuracy of the diagnosis can be greatly improved!

Once the diagnosis is confirmed, it is important to give systematic treatment, and patients receive professionalinfectious diseases, respiratory medicine, and many other medical specialists.These medics are the equivalent of the army.Special Forces.Having a better ability to kill the enemy would be a better way to save a diagnosed patient!

In addition to fever, there are other symptoms that must also be taken seriously

The clinical manifestations that may be triggered by this virus have been described in detail in the fifth edition of the treatment guidelines:

Based on current epidemiologic investigations.Incubation period is 1-14 days, mostly 3-7 days. The patient's symptoms are characterized byFever, malaise, dry coughPredominantly, a few patients are accompanied by nasal congestion, runny nose, sore throat and diarrhea.

In the new paper published by the team of academician Zhong Nanshan, we can also see that 87.9% and 67.7% of patients with clinical manifestations ofHospitalizationFever and cough were present. While the chances of vomiting (5%) and diarrhea (3.7%) symptoms are not high. Severe patients tend to develop respiratory distress after one week of illness Severe patients progress rapidly to acute respiratory distress syndrome with the possibility of septic shock.

summarize

Although there are some patients who do not develop significant fever early in the development of the novel coronavirus, during initial screening, theTaking your temperature is a very important part, is among the links that should never be abandoned.

In the face of the spread of this new coronavirus pneumonia, please pay attention to personal protection, must reduce the number of times you go out, must do not gather, less to the confined space, wear a mask, wash your hands diligently, return to work is even more important to pay attention to wear a mask, pay attention to hand hygiene, pay attention to the work environment as well as the home environment of the ventilation and hygiene conditions to maintain.

Remind friends must always pay attention to their own body, pay attention to whether they have fever symptoms, in addition to the emergence of obvious dry cough, chest tightness should also be alert, such as high suspicion that they are new virus pneumonia patients, theIt is recommended that you always go to the nearest fever clinic with protection, seek professional medical help, and have a ct examination as well as blood tests taken., it is imperative that you do not hide your condition, otherwise the damage caused if it spreads can be immense.

I am Xie Xinhui, who insists on using simple language to explain the knowledge of complex diseases, it is not easy to code, if you agree with my point of view, please help to point out a concern or click a like it, thank you!

Is there a significance of temperature testing during the incubation period of the new coronavirus?

It certainly makes sense. It is the last line of defense in detecting a potentially infected person. The current incubation period for the new coronavirus is about 1 to 14 days, usually 3 to 7 days. And fever is still the main symptom of a person infected with the new coronavirus. Many people do not know that the strangers they come in contact with are not infected with the virus. Therefore, the purpose of testing the temperature of all people entering and leaving the neighborhoods, supermarkets and other places is to detect and isolate them at an early stage, which is the most important measure for preventing infectious diseases, and also to allow infected people to be diagnosed and treated at an early stage, which is as significant as preventing a second outbreak of the neo-coronavirus infection.

What if I'm worried that the virus is in incubation and can't be detected without a fever?

This problem, in fact, do not have to worry too much. District, supermarket testing is a group prevention and control measures for all people to do, and for those who may have in the incubation period of the virus, the country has now implemented medical isolation and observation and home isolation measures, so as to avoid the possible potential risk of spreading to healthy people. Now many places have stipulated that if you come back from abroad regardless of whether you have been to the infected area, you need to isolate yourself at home for 14 days to avoid contact with others; close contacts with confirmed and suspected patients will be placed under centralized isolation for medical observation, and shall not be separated from the isolation area without authorization, and once these groups of people are found to have fever or other respiratory symptoms will be reported by the management staff, and be transferred to the sentinel hospitals to be examined. Therefore, it can be seen that the country's prevention and control of this epidemic is very strict, never miss a person, on the willful concealment of non-reporting of people and the corresponding criminal penalties (will go to jail).

Finally, I would like to remind everyone again that good personal protection is the most basic means to protect ourselves from infection. It is now the most critical time to go out less, wear masks, wash hands regularly, ventilate the room and strengthen the body, so as not to let the virus take advantage of it.

Welcome to like, forward, leave a message, I am physician Yang Hao, focusing on common diseases, multiple diseases diagnosis and treatment, chronic disease management, health science. If you want to know more about medical knowledge, welcome to pay attention to this headline!

In February 2020, there was a sudden outbreak of neocoroniasis in the country and a number of people lost their precious lives due to this neocoroniasis virus.

After this painful lesson, the people of the country have summarized a set of very experienced measures to prevent the epidemic, and it is believed that when the epidemic is detected, it will be very good to narrow down the scope of its contagion.

Now wherever you go, you need to do a code entry and temperature test. If your temperature is not normal, then you are not allowed to enter this mall, supermarket, or the station there is a possibility that you will also be tested for nucleic acid, which is a good precautionary measure.

Is such a precautionary measure as temperature testing useful and meaningful or not?

We all know that the new coronavirus patients his seizure state is: fever, cough, chest tightness, weakness in the limbs and other states.

The most obvious state is fever, so even if you have a regular normal fever, once you're detected at the station with an abnormal temperature, you can't go in.

So is temperature measurement very effective in detecting the risk posed by the new coronavirus or not, and is it meaningful?

Whether it's a person or a thing, you can't be perfect, so let's talk about the strengths and weaknesses of temperature testing.

This time, the new coronavirus, its morbid state is mainly fever, once people suffering from this virus, they will definitely have a high fever constantly. Once there is no temperature detection in places with heavy flow of people, then these patients with fever will not be detected, and they will easily come into contact with a lot of people, which will lead to a mass contagion.

That's why temperature testing can be a good way to rule out some of the risks, and once a person with an abnormal temperature is tested, they don't need to be questioned by a professional, they can just be pulled in for a nucleic acid test to isolate them and see if there's a problem.

That's why temperature testing is a good way to screen for risk.

To return to his shortcomings, the temperature test is only able to screen for some of the risks, but it is not yet able to rule out 100% of the risks.

Why?

As the weather gets colder since the beginning of winter, the cold weather is a good environment for the virus to survive, while its infectivity and survival time in the human body will reach a longer period of time.

It is likely to mutate, just like in asymptomatic patients.

What is an asymptomatic patient?

Asymptomatic patients are just like us normal people, no fever, no cough, no cold, no abnormality, this time the temperature test for asymptomatic patients do not play a big role at all.Since they do not have fever at all and they are still carrying this virus, only a nucleic acid test can detect whether they have this new coronavirus, and with such a heavy flow of people in the market every day, who can tell who is an asymptomatic patient?

All temperature tests are also not 100% sure if a population is safe.

Then there are so many people we come into contact with in our daily lives that we can't tell which is an asymptomatic patient and which is normal.

The Spring Festival is approaching soon, and the volume of people in the Spring Festival is very large, and the number of people in contact with it is also very large, so once there are asymptomatic patients in it, then the consequences can be imagined.

What kind of precautions do we need to take to get through this Spring Festival and get home safely?

1, must wear a good mask when you go home, try not to socialize with others when in the station, try not to eat in the car, so as not to cause cross-infection, if the journey is farther friends can reduce the number of meals.

2. Those who are able to stagger the peak of the Spring Festival in advance must take leave to go home in advance.

Because the Spring Festival traffic is very large, from all over the world, no one can guarantee that they have contacted those new crown patients and returning Chinese, in this group of people have a virus carrier, then it will be very easy to cause a large-scale aggregation of infections, so all friends can be able to go home in advance to take time off to go home as far as possible in advance to take time off to go home, don't rush to return in the Spring Festival that few days, so as to avoid aggregation of infections.

Those who have a car can drive themselves home is also the safest way.

3. For some people like these, try not to go home and choose to spend New Year's Eve locally.

For example, the elderly pregnant women with diseases, such people resistance is very poor, not to mention the new crown virus is highly contagious, even if a common influenza, they are also very easy to be infected, once the journey home in contact with the new crown virus carriers, then it will be very easy to be infected, so this year, like some of these people, it is best not to go home to New Year's Eve, safety first, if the family has the conditions, then you can If you have the means at home, you can drive home, so that you can avoid coming into contact with a lot of people.

Summarize: soon to be the New Year, I am here, I hope you can go home safely for the New Year, in the way home, be sure to pay attention to personal epidemic prevention measures, safety first.

Of course it makes sense.

I. Is temperature testing meaningful during viral incubation?

Last year the epidemic broke out in Wuhan and spread throughout the country. This year, the first phase of the epidemic in China has ended, but the domestic outbreak has been delayed by the influence of the epidemic abroad.

In contrast to cases, the most worrisome are asymptomatic infections, where patients have no obvious clinical symptoms but are contagious.

In order to detect suspected cases at an early stage, hospitals, schools, neighborhoods, supermarkets and other public places are using temperature testing as one of the most important means of epidemic prevention and control.

However, during the incubation period of the virus, an asymptomatic infected person may be asymptomatic and not have a fever, but also be contagious, so is there still a point to temperature testing?

It certainly makes sense. Academician Zhong Nanshan mentioned that China has a relatively small percentage of asymptomatic infections.

Looking at asymptomatic infections alone, one would think that the number is quite high, but compared to the number of cases, the number of asymptomatic infections is very small, so it is necessary to identify potential cases in the population through temperature testing.

II. Temperature testing is only the initial screening, nucleic acid testing and CT screening are the focus

One: Not all patients with fever are cases; some have fever triggered by respiratory illnesses and other causes. Temperature testing is only the first step in screening

Second: If the patient has fever symptoms, he or she will be asked by the hospital to go for a nucleic acid test so that the case can be detected early. In addition to the nucleic acid test, a CT test is also required to confirm the case, and many people are just detected early in the disease.

Third: Some asymptomatic infections also turn into confirmed cases at a later stage, so early temperature testing is necessary to identify febrile patients.

Some patients have a long incubation period, even more than 3 weeks, but if it is a case, there will be obvious symptoms, such as: fever, cough, fatigue, etc. Therefore, it is very meaningful to combine the three tests: temperature test, nucleic acid test, and CT test to identify asymptomatic infected people or cases.

Personally, I think it makes sense

The temperature test will be coupled with registration so that each person's journey through the line will be recorded for later tracking and faster tracking of contacts at the same time!

Such a working atmosphere can also remind everyone should pay attention to, but also can find some other problems, like yesterday I went out of the neighborhood to do a little thing, back is also a temperature test, in front of an old man, she brought a cotton mask, the staff in the detection of the temperature of the problem was found, free to give her a medical mask, and at the same time to tell her that such a mask is useless, and prompted her to Go back to pay more attention to the relevant safety knowledge!

From New Year's to now basically everyone has been quarantined at home for 14 days, so the incubation period has basically passed the first stage, and community temperature testing can actually have a role to play because there does exist a part of the population that is afraid of being quarantined to intentionally hide the fever, so that it will be prevented before it is too late!

This morning I read the news that an old man in Harbin deliberately concealed the fact that he had been to Wuhan, resulting in the whole neighborhood was closed, harming people and themselves! So it is also recommended that neighborhoods or communities do a good job of screening people, so that we all do a good job, our environment will be safe!

In any case, it's definitely beneficial for places to do this, so we should be open to fully supporting the work of others to fight this epidemic and achieve ultimate victory ✌.

I believe that lately everyone who goes in and out of villages, neighborhoods, or who comes home from the outside will have their temperature taken at the entrance to their neighborhoods, village intersections, supermarkets, highway intersections, and so on.

But then, some people will feel that they are just going in and out of the neighborhood, and they have not gone outside, and they think that this is very cumbersome and troublesome, and they are not willing to cooperate with the health care workers and assistants, so Kirk will tell you whether it is necessary to take temperature measurements during the epidemic of the new coronavirus or not:

1. Elevated body temperature is one of the clinical manifestations of novel coronavirus pneumonia:Fever, dry cough and fatigue are the typical clinical manifestations of this new coronavirus pneumonia. Among these three symptoms, dry cough and fatigue can be easily concealed by the patients themselves or not easily detected by the patients themselves, so it is not easy to be detected, only the symptom of fever can be detected by the instrument, which is an objective data reflection.

Under normal circumstances, the human body's axillary temperature is between 36.0-37.0, when the axillary temperature exceeds 37.3, it means that there are symptoms of fever. For people with a temperature over 37.3, the relevant medical and control personnel need to ascertain whether they have a history of going out and visiting crowded places, and then follow up by asking whether there are any other symptoms as well as taking temperature measurements to completely rule out the possibility of new coronary pneumonia.

2. The incubation period of C.N.C.P. is about 14 days.A few days ago, Mr. Zhong said that among the more than 1,000 clinical cases, the incubation period of one case was 24 days, but the incubation period of the other cases was basically less than 14 days, and during these 14 days, we don't know when the patient develops the disease, and we can only use the patient's history of contact, history of going out, and their own objective evidence to determine whether there is a risk of the development of new coronary artery disease.

3. Temperature testing is a convenient, rapid method of measuring theCompared to other blood tests and imaging tests, temperature measurement can be used to screen for fever and then confirm the diagnosis, which is now done with an electronic thermometer, which basically measures the temperature in a few seconds.

I am focusing on science and health knowledge of small grams, looking forward to your likes and comments, attention to small grams, to learn more about health knowledge.

There is significance for the group with fever symptoms, but currently most of the patients in the incubation period do not have fever, so the significance of just taking the temperature is not very significant, and it is recommended to reduce the movement of the crowd and limit the human contact with the earth is a more direct and effective approach

According to current experts, the body temperature will be normal during the incubation period, but it is still used as an important condition in screening because it spreads most intensely when it is elevated

I think it still makes sense. At least you can pinpoint your temperature changes on a daily basis, and it's a reminder to yourself to keep an eye on your temperature changes at this very time. Once there is a change in temperature, you can take precautions as early as possible, and you may be alerted earlier. And will not involve the family, so it is better to take the temperature more often!
