Since 2019, the new coronavirus has broken into people's lives. During this period, humans have fought a vicious "struggle" with the related virus . Now, although the infectivity of the new coronavirus is greatly increasing, its pathogenicity has been greatly weakened, and it is even almost the same as the flu! Therefore, many places in our country have directly implemented the policy of comprehensive liberalization.
In the next month, we will face the most important festival in China, the Spring Festival. During the Spring Festival, there will be a large movement of people. Not only migrant workers will have to return to their homes, but they will also visit relatives and friends during the New Year. Therefore, many people say that China will face multiple waves of infection peaks. So, is there any scientific basis for this statement?
Will your throat feel itchy at the beginning of COVID-19 infection?
new crown is new coronavirus pneumonia Novel coronavirus infection, patients may have symptoms of itchy throat at first, but they may only have a fever or a slight cough at first.
Novel coronavirus infection has no specific clinical manifestations. The early symptoms are mainly fatigue, dry cough, and fever. A few patients will have symptoms such as itchy throat, muscle soreness, sore throat, runny nose, nasal congestion, diarrhea, etc. The clinical manifestations are diverse.
Therefore, the novel coronavirus infection may initially cause a scratchy throat.
If you often go out and come into contact with patients infected with the new coronavirus, and you have symptoms of itchy throat, you can conduct a new coronavirus antigen test and a new coronavirus nucleic acid test, which can help with diagnosis, early detection, and early treatment.
For patients infected with the new coronavirus, the treatment principle is symptomatic and supportive treatment, such as fever, muscle aches, headaches, etc., which can be treated with acetaminophen and ibuprofen . In addition, special groups such as children, pregnant women, lactating women, and the elderly are advised to consult a doctor and not blindly take medication.
Will China face multiple waves of infection peaks?
After further optimization and adjustment of the new crown pneumonia epidemic prevention and control measures, the number of infections has increased rapidly, and many parts of the country will usher in the first wave of epidemic peaks; experts said that the epidemic in my country is in a stage of rapid rise.
In the future, various places will usher in the peak of the epidemic; recently, Anhui, Zhejiang, Hunan, Jiangxi and other places have predicted that the first wave of the epidemic peak may arrive around January 2023. However, due to the lack of accurate data, these predictions are uncertain.
With the relaxation of epidemic prevention and control measures, cross-regional personnel movement has become more convenient, and people's willingness to travel has gradually accelerated. The total passenger flow during New Year's Day and Spring Festival may increase significantly. The trend of the epidemic before and after the Spring Festival also attracts attention.
Experts believe that the upcoming Spring Festival travel rush may lead to a new round of epidemic peaks. Data experts who predict long-term epidemic models predict that the national epidemic will form a "real peak" around the Spring Festival in 2023, and begin to slowly decline after January 31.
After the Spring Festival, the national average infection rate may reach one-third. In addition, experts pointed out that the epidemic in my country will experience "one peak and three waves" this winter.
Experts said that the first wave of the epidemic will be from mid-December to mid-January, mainly in cities; the second wave will be from the end of January to mid-February, when the flow of people before the Spring Festival leads to an increase in the epidemic; from late February to mid-March, the resumption of work after the Spring Festival will lead to the third wave.
As long as there is a flow of people, all infectious diseases will spread. The more frequent, rapid, and distant the flow of people, the faster and more frequent the spread will be.
With the rapid increase in the number of infections, some places are facing huge medical pressure. In response to new situations and changes such as the increase in the number of infections and the increase in crowds during the Spring Festival, various localities are effectively monitoring, analyzing, and judging epidemic information, and have prepared material reserves, transportation capacity reserves, and emergency plans in advance to minimize the impact of the epidemic peak.
China officially released a work plan, which requires ensuring that people can visit relatives and go home for the New Year and resume work in an orderly manner. All regions can explore the implementation of flexible leave and off-peak leave policies to reduce the pressure on the public to travel together. In addition, some places also encourage people to "return to their hometowns at staggered peak times" and travel at staggered peak times to suppress the peak of the epidemic.
Zhong Nanshan said: The new crown is indeed not a big cold.
Now, all netizens are reflecting that the new crown is not a cold.
In fact, COVID-19 is really not a big cold. We often confuse colds and influenza. Therefore, we actually compare COVID-19 with influenza, not COVID-19 with a cold.
The symptoms of a cold are indeed very mild. It usually lasts a week. It is a self-limiting disease . In fact, colds can be cured without taking medicine.
But influenza is different. Influenza is caused by influenza viruses. Influenza also has systemic symptoms, such as fever, cough and severe pneumonia ; and, depending on the virus, its pathogenicity is also different.
For example, the 2008 H1N1 influenza , which everyone is deeply impressed by, was also very serious that year. There was once a highly pathogenic avian influenza H5N1 that had been infected by humans, and the fatality rate was very high!
Therefore, compared to influenza, even if some pneumonia appears in some parts of it, this kind of pneumonia is far from reaching the level of "white lung" as netizens call it. After this treatment, people will get better and return to health soon.
What is the chance of being infected with COVID-19 again?
The chance of being infected with the new coronavirus again is usually very small. After being infected once with the new coronavirus, the immunity formed by the human body will play a certain protective role. The probability of reinfection with the new coronavirus within 3 to 6 months is relatively small. At present, the main popular new coronavirus strains in China are and Omicron , and most people may not be repeatedly infected with Omicron for a long time.
So, will the symptoms of reinfection with the new coronavirus "worse"?
Under normal circumstances, whether repeated infections with the new coronavirus will worsen depends on the patient's immunity at the time, the pathogenicity of the new coronavirus and its mutant strains, and other factors, and cannot be generalized; the new coronavirus is an acute respiratory infectious disease caused by the new coronavirus infection. Due to a history of infection, patients will not have permanent immunity.
If the patient has strong immunity during repeated infections, the incidence rate of the new coronavirus and its mutant strains will be lower, and the condition will generally not worsen. In contrast, the body has cellular memory of such viruses, and symptoms may be mild.
However, if the patient's condition is reversed, or if a more pathogenic variant emerges, the symptoms of repeated infections may be more severe.
What should I do if my nose is severely blocked due to COVID-19?
New coronavirus pneumonia usually refers to new coronavirus infection. Severe nasal congestion in patients with new coronavirus infection can be improved by fumigating the nose with hot steam, rinsing the nasal cavity with saline, and taking medicine.
1. Hot steam fumigation
The symptoms of nasal congestion caused by the new coronavirus infection are severe. Patients can fumigate their noses with hot steam from hot water, which can also expand the nasal cavity to a certain extent, thereby relieving severe nasal congestion.
2. Rinse the nasal cavity with normal saline
In addition, patients can also flush the nasal cavity with normal saline. This method can effectively expand the nasal mucosa to a certain extent, thereby relieving severe nasal congestion symptoms. However, you must be careful when cleaning the nasal cavity to avoid using too much force and damaging the nasal mucosa.
3. Take medicine
Patients infected with the new coronavirus often have severe nasal congestion symptoms, usually accompanied by fever, fatigue, cough and other physical discomfort symptoms. Patients can follow the doctor's advice and take medicine to improve it. Such as Lianhua Qingwen capsule , Huoxiang Zhengqi capsule , etc. These drugs can help improve the symptoms of severe nasal congestion caused by new coronavirus infection.
In addition, in addition to the above methods that can improve the symptoms of nasal congestion, patients can also apply hot towels to their noses to improve the symptoms of nasal congestion.
Although the country has now implemented a comprehensive liberalization policy, we ourselves cannot give up on self-protection. Regardless of whether we have had a sun exposure or not, we must pay attention to self-protection, because we may also face the risk of secondary infection of by . We must not relax our self-protection!
