Will the weather be hot?

Will the epidemic situation get better in hot weather? Together, I believe everyone has a deep understanding of this word, especially when the epidemic broke out in the past two years. I also believe that many people hope that the epidemic will get better soon. Then let's understand whether the epidemic situation of high temperature weather will improve.

Will the weather heat epidemic get better? 1 202 1 Will the epidemic situation get better in summer?

The intensity of the epidemic may decrease in summer, but it is impossible to disappear naturally.

Europe and the United States are not fully prepared for epidemic prevention and control, but at present we can see that different countries adopt different strategies. China's strategy is to control the epidemic in the shortest time. Europe and the United States may consider controlling the epidemic for a long time and reducing economic losses. However, with the development of the epidemic, the strategies adopted by many countries in Europe and America are very close to those of China. International students and colleagues should keep a social distance, often wear masks and wash their hands.

In essence, the outbreak and prevention of coronavirus pneumonia-19 is a war between human beings and viruses. Almost everyone can't live without it. He needs everyone's participation and active cooperation, obeys the management arrangements of the government, professional institutions and personnel, treats the epidemic scientifically and does well, so as to better usher in the victory of the "war epidemic".

Will the epidemic end in the summer of 20021?

It's not over yet.

China has passed the dark moment, but now Europe has suddenly become the main center of the epidemic, which has brought us great uncertainty.

China will still face greater import risks in the future. Judging from the current global epidemic prevention situation, it is almost impossible to end the epidemic this summer.

Except China, the global epidemic has not been effectively controlled. Europe has become the center of the epidemic, and the United States is also spreading. At present, it is difficult to accurately predict when this international epidemic will end.

How to do personal protection well

1, the first is to wear a mask correctly. One end of the metal strip is facing up, and then a protective mask is put on the nose, mouth and chin to ensure that the bridge of the nose is in the center of the mask. Pull back the mask strap and put it behind your ear. When the mask is covered, pull it down. The metal strip should be pinched once to ensure the tightness of the mask.

2. It is not recommended to burn, scald or cut the used mask. This can not only meet the needs of disinfection, but also pollute the environment and cause potential safety hazards. If there are no symptoms, just ordinary personal protection, used masks can be thrown directly into the trash can.

3. If the mask is used up in the hospital or infectious diseases are suspected, it should be put into a medical waste garbage bag. If you want to sneeze, cover it up carefully. Cover your nose and mouth with a disposable tissue or handkerchief.

4. If there is no paper towel or handkerchief, cover your nose and mouth with clothes sleeves. Do not use your hands.

5. For personal protection, it is very important to wash your hands frequently and teach you the correct hand washing procedure. Wash your hands with water and add hand sanitizer or soap.

6. In the face of the epidemic, the best preventive measure is to go out as little as possible, don't go to crowded places, often open windows at home for ventilation, keep clean and hygienic, eat healthy, get enough sleep, and don't stay up until midnight. Enhance resistance, don't go out if you have nothing to do, don't go out to join in the fun, wash your hands frequently when you go home, and wear a mask when you go out. This is the best care for everyone, including yourself, your family and your friends. Let's start from me to prevent and control, and pay attention together.

Will the weather heat epidemic be better? Low temperature is more likely to cause virus epidemic.

Every year, the eastern spring is a season of high incidence of various infectious diseases, such as the common cold, flu and bird flu. Because the survival time of the virus in the outside world is enhanced at low temperature, and the chance of infecting people is increased, the time of novel coronavirus epidemic and SARS is relatively close.

With the increase of environmental temperature and humidity, the survival time of the virus in the outside world decreases.

Because the research data of novel coronavirus is still relatively scarce, considering that novel coronavirus and SARS are close, we can refer to the previous research data of SARS virus. When SARS-CoV survived in the environment, at room temperature (22-25 degrees), the virus activity began to decline after 5 days and was completely inactivated after 3 weeks. When the temperature is 38℃, the virus inactivation speed is obviously accelerated, such as high humidity (>; 95% RH), which was further accelerated and lost most of its activity in about 24 hours.

Does it mean that if the temperature is high in summer, novel coronavirus will die and the epidemic will be gone? Of course not.

In terms of indirect infection, especially pollutants with viruses, higher temperature and humidity will indeed reduce the virus activity more quickly. However, environmental and climatic factors have little influence on direct and close droplet transport. Because the droplets are basically unaffected by the external environment temperature.

In a word, if we want to end the epidemic at an early date, we can't hope for climate warming, but rely on angels in white, where we are fighting in the front line. As ordinary people, when going out, we should implement isolation measures and do a good job of self-protection to end the epidemic as soon as possible.

Another way of saying it

I don't agree with the statement that the virus will disappear by itself when the weather is hot. The reason why some people make such a prediction is actually based on the judgment of the development of SARS epidemic in that year. SARS first broke out in Shunde, Guangdong on June 200216, and basically ended on July 2003 13, lasting eight months.

The outbreak time in COVID-19 is similar to that of SARS. Whether it means that the temperature rises, the virus will lose its activity and gradually disappear. Many netizens have different opinions and debate endlessly. In this regard, experts made it clear that the prevention and control in novel coronavirus is in the primary stage, and the research work has just started. Whether the virus will lose its activity due to rising temperature has not been scientifically determined.

So, how does temperature affect virus activity?

First of all, it is undeniable that the weather has an important influence on the spread of the virus. The fluctuation of temperature will not only reduce the human body's resistance to the virus, but also be the reason for the spread of the virus. As we all know, when the seasons alternate, people are particularly vulnerable to viruses, such as influenza, which is also the truth of the old saying "Spring covers autumn".

Relevant data also show that too high and too low humidity are not conducive to the survival of the virus. Generally speaking, a dry environment is conducive to the survival and spread of the virus. However, some scholars have suggested that the humidity of about 75% is most conducive to the spread of the virus. What about the temperature? The virus is not heat-tolerant, but it cannot spread if it is too cold. Studies have shown that this virus is the most fierce at the turn of winter and spring. The SARS epidemic and the outbreak time of this epidemic are at this node, and the temperature is around 20 degrees.

In an environment with less rain and snow, the virus is easy to spread. When autumn and winter alternate with winter and spring, cold air frequently appears, which is the most vulnerable time period to virus attacks. So be sure to keep warm, rest, drink plenty of water, wear a mask and protect yourself.

In addition, the virus is sensitive to dryness, sunlight, ultraviolet rays and even air quality. When coronavirus is exposed to the actual external environment, it will not survive for a long time. Under the current temperature and humidity in the north, coronavirus will not survive in vitro for more than a few minutes in the relatively dry sunshine during the day.

According to authoritative experts, the virus can be completely inactivated at 56℃ for 30 minutes, and the virus will soon lose its infectivity at room temperature around 25℃, which means that the higher the temperature, the shorter the survival time of the virus, and the end of the SARS epidemic is summer. Someone asked if the sun could inactivate the virus, but of course not. But when the weather is good, just put your clothes and bedding in the sun, and keep indoor ventilation, ventilation and air circulation, which will also improve your body's resistance to viruses.

However, we can't pin our hopes on the change of temperature, which is very dangerous and stupid. The SARS epidemic that year, with the efforts of the whole world, finally won. What's more, now is the critical moment of the "epidemic" of this war, and it is even more necessary to be vigilant and fight bravely. The spread of the virus is shocking. Jiang Rongmeng, a member of the expert group of the National Health and Wellness Committee, said that COVID-19 could survive for five days under the right temperature and environment.

It is impossible to say that summer comes and the weather disappears when it is hot. Therefore, in the face of the severe epidemic, each of us should have a high sense of responsibility, obey the arrangement of the government, do a good job of self-protection and not cause trouble to the country. We firmly believe that under the strong leadership of the party and the government, and with the joint efforts of all walks of life, we will certainly be able to overcome the raging epidemic!

No, it is dormant at most, lurking in the soil. In Russia, dormant viruses can be found in frozen soil more than 10 thousand years ago. This kind of thing between living things and non-living things is difficult to destroy according to the surface temperature. That is, boiling water can destroy protein and kill protein.

I can only hope that he gets tired of playing and goes to bed when he is bored. This kind of thing is like a miniature bomb made by God specially for us. If people do more evil, give us another chance. Therefore, we still have to be kind-hearted, develop scientifically, be content with happiness, and the economic development driven by greed and pleasure will eventually be buried by greed.

Will the epidemic situation get better in hot weather? Will there be a large-scale outbreak next year?

"This may be a little smaller." Professor Cheng Yiling said that with the development of vaccines and the escalation of epidemic prevention and control measures, COVID-19 will be effectively prevented and controlled. There is a good chance that there will be no large-scale outbreak in COVID-19 next winter. With the climate warming, COVID-19 may disappear like SARS.

Will the virus disappear when it is hot?

As the weather gets hotter and hotter, many people are concerned: will the virus disappear? Recently, "die-hard expert" Zhang Wenhong responded when interviewed by the media.

Zhang Wenhong, the leader of the Shanghai medical expert group, was circled by many netizens.

Zhang Wenhong believes that it is hard to say now, and the high probability may be affirmative.

"You should remember that in 2009, the flu in the United States was seasonal, just as SARS was seasonal in China. The flu in the United States began in March and April, and then a large-scale outbreak began the next year. Therefore, it is not that the virus does not exist in summer, otherwise it will not last until summer. How can it continue to the next year? "

Zhang Wenhong warned that one thing is certain about this virus. As long as you open all the windows, you'd better try your best to ventilate. For example, in Thailand, it is more difficult for the virus to spread. Therefore, it is very important to open the window for ventilation. In summer, one is high temperature and the other is ventilation, which originated in winter. After several months of prevention and control, the virus came down in waves, at this point in time.

When will the new case be closed?

Recently, Zhang Boli, member of the expert group of the Central Steering Group, academician of China Academy of Engineering and president of Tianjin University of Traditional Chinese Medicine, accepted an exclusive interview with the People's Daily new media in Wuhan.

Zhang Boli thinks:

"We analyzed the epidemic evolution data. At present, in other areas except Hubei, the new cases were basically cleared at the end of February;

Other areas in Hubei province except Wuhan are estimated to be basically cleared in mid-March;

Wuhan is expected to achieve basic zero clearing by the end of March.

Judging from the overall development trend of the epidemic, it is like this. However, purity is not absolute, and occasionally several new situations will appear. "

When can I "take off my mask"?

Zhang Boli believes that it is estimated that by the end of April, except Hubei, all other provinces and cities in China can basically take off their masks and return to normal life and production order. Hubei province, especially Wuhan city, may be about 1 month later than the whole country. "However, I don't advocate taking off the mask in such a hurry. Even if you return to work and restore normal order, it is better to slowly take off your mask. " Even if the whole country is "cleared", the good habits of meeting less, washing hands frequently and wearing masks should be maintained for some time.
