Introduction: Unconsciously, the new crown has existed in life for nearly three years, and the emergence of the new crown virus has broken the original peaceful life and hindered the development of the economy.
In the face of the growing number of confirmed cases, people can't help but panic, when will the new crown that has lasted for nearly three years disappear?
The new crown virus has changed the world like never before
The impact of COVID-19 on the world is so profound that we forget that the highlight of medicine is that it once used modern medicine to effectively eliminate major infectious diseases such as smallpox and poliomyelitis, and it is modern medicine that makes us forget how fragile human beings are in the face of diseases.
At the end of 2019, the new crown virus quietly arrived, the new crown virus belongs to the coronavirus, is also a widely existing type of virus in nature, so far, the coronavirus only infects vertebrates, can cause respiratory, digestive tract and nervous system diseases in humans and animals.
After infection with the new crown virus, fever, fatigue, dry cough are mainly manifested by fever, fatigue, and dry cough, and some patients are accompanied by symptoms such as nasal congestion, sore throat and diarrhea.
Since the emergence of the new crown virus, wearing masks to disinfect, measuring body temperature to this vaccine to go out to sweep health, doing nucleic acid testing has become our daily routine, and studying abroad, visiting relatives, going out on business and other cross-border personnel flows, but today the new crown epidemic has become a luxury.
When will the COVID-19 pandemic end? Huang Jianping, an academician of the Chinese Academy of Sciences, made a prediction
For the general public, the most concerned question is when the new crown virus will end? The team of Huang Jianping, an academician of the Chinese Academy of Sciences, made a prediction: the new crown will probably end at the end of 2023.
The predictions made by Academician Huang Jianping's team did not come out of thin air, but based on the results of many experiments, they used the new crown self-test system to repeatedly speculate on the current epidemic situation, and the accuracy rate was as high as 94%.
This result is based on the current development of the pandemic, and if there are stronger COVID-19 strains in the future, the COVID-19 pandemic may not end in a short period of time.
Therefore, before the end of the epidemic, I hope that everyone will maintain an optimistic attitude, can not be arbitrarily rotten, and during the spread of the epidemic to listen to the arrangements of the state, because the new crown virus is very cunning, with a strong ability to spread, even if the new crown vaccine has been accepted, there is still a possibility of infection with the new crown, so once the body has obvious discomfort, you should seek medical treatment in time.
How long can the new crown virus survive at room temperature?
After the new coronavirus leaves the human body, the room temperature retention time in the natural environment is actually very short. In outdoor environments, especially in the sun, survival time is only a few minutes or so.
In addition, the survival time of the new crown virus mainly depends on whether the ambient air is circulated, ambient temperature and humidity and other factors.
The new crown virus prefers cold and is most stable at 4 ° C, where it can survive in the environment.
In the air circulation environment, aerosols, and the patient's droplets and saliva, the survival time of the virus may be 30-180 days, on air-sealed smooth objects for 2-3 days, up to 5 days, and the survival time of dry clothes generally does not exceed 30 minutes. 、
However, viruses do not like high temperature and humidity environments.
How long is the incubation period of the new crown virus?
According to the characteristics of the current epidemic situation, some infected people may not have a positive nucleic acid test result until about 14 days, so the maximum period currently identified as 14 days is 14 days.
However, with the mutation of the virus, mainly the Omikron mutant strain, its incubation period is significantly shortened, generally in 3 to 5 days can be onset, even if the incubation period is relatively long, generally in 5 to 7 days.
What are the symptoms of the onset of the disease after contracting the new crown?
The "Diagnosis and Treatment Plan for New Coronavirus Pneumonia" released by the National Health Commission shows that fever, fatigue and dry cough are the main manifestations. A small number of patients are accompanied by symptoms such as nasal congestion, runny nose, and diarrhea.
In severe cases, dyspnea occurs more than a week later, and in severe cases rapidly progresses to acute respiratory distress syndrome, septic shock, difficult-to-correct metabolic acidosis, and coagulopathy
At the moment of the epidemic, how can we take self-protection measures?
First, appropriate window ventilation, home should open the window ventilation for a period of time every day, strengthen air circulation, can effectively prevent respiratory infectious diseases.
Second, wearing a mask can effectively reduce the risk of infection, avoid going to crowded places, and wear a mask when necessary.
Avoid closed, air-circulatory public places and crowded places, especially for children, the elderly, pregnant women, and people with underlying medical conditions.
Third, pay attention to personal hygiene, wash your hands frequently, scrub with soap and water for more than 20 seconds, and use hand sanitizer to clean your hands when there is no condition.
Fourth, timely observation and medical treatment, if there is cough, chest tightness, fever, cough shortness of breath and other respiratory tract infection symptoms, you should wear a mask in time to seek medical treatment
At the moment of the epidemic, doing a good job of self-protection is the best way to protect yourself and protect your family!
