In the past week, the number of new crown infections has skyrocketed, especially in large cities such as Beijing, Guangzhou and Chongqing. There are also many people around Yangshengjun who are "yang", which causes everyone to be a little nervous, and as soon as there is a wind, they wonder if they have been hit.
So, what kind of discomfort does it appear that it is possible to be infected with the new crown? Let's listen to what the experts have to say~
What are the symptoms after being infected with the new crown? The new crown infection mainly has "ten symptoms", including fever, dry cough, fatigue, loss of smell and taste, nasal congestion, runny nose, sore throat, conjunctivitis, myalgia and diarrhea. Clinical observations have found that patients infected with the new coronavirus will have one or more of the "ten symptoms", each individual is different, but the course of the disease after infection has certain similarities. Li Tong, chief physician of the Department of Infectious Diseases of Beijing You'an Hospital and a medical expert at Xiaotangshan Fangcang Hospital, once summarized the "symptom analysis" of nucleic acid turning negative from the first day to the 7th day of onset after ordinary young and middle-aged patients were infected with the new coronavirus——
First day of illness: mild symptoms. You may feel mild dry throat and sore throat, and weakness. The second day of illness: fever began to appear, and some young people had a high fever of about 39 degrees Celsius. At the same time, pharyngeal discomfort increases. Day 3: The day with the heaviest symptoms. High fever above 39 degrees Celsius, body aches and weakness, sore throat intensified.

On the fourth day of onset: the peak of body temperature begins to drop. Many people have a normal body temperature from this day and no longer have a fever. But still sore throat itchy. Some people started to runny nose and cough. On the fifth day of onset: the body temperature basically dropped to normal. But nasal congestion, runny nose, sore throat, cough, and physical weakness remain. Day 6: no more fever. Symptoms such as cough and runny nose are aggravated. The respiratory mucosa caused by the virus in the early stage is destroyed, and the body excretes necrotic cells through runny nose and coughing. Nucleic acid conversion may occur. Day 7: All symptoms begin to improve significantly. Nucleic acids are likely to turn negative. Li Tong once said that the onset process of ordinary young and middle-aged people is suitable for the above situations, and it will generally heal in 1~2 weeks, and people who have been vaccinated with the new crown vaccine and completed booster immunization have a shorter course of disease and less severe disease. In some elderly people, especially those over 70 years old with underlying diseases, the fever course is more complicated. If the elderly are infected with the virus for 5 days before and after, if they have obvious symptoms of holding their breath, they need to use lung CT images to diagnose whether there is lung infection.
The strains circulating in the North and the South are different?
More "poisonous" in the north?
Some people say, how do you feel that after infection in the north and south, the reaction is not very similar? Looking at social media, northerners seem to be a little more miserable?
Xu Wenbo, director of the Institute of Virology of the Chinese Center for Disease Control and Prevention, recently introduced that the variant currently circulating in Beijing is mainly BF.7, and the variant circulating in Guangzhou is mainly BA.5.2. What is the difference between these two variants? Tong Zhaohui, director of the Beijing Institute of Respiratory Diseases, pointed out: Omicron has different branches, and there is no difference in pathogenicity! Whether it is the south or the north, the whole is mainly asymptomatic and mild, mostly acute upper respiratory tract infections. "In any case, as long as this virus is still Omicron, in fact, the toxicity, pathogenicity and infectivity of its virus will not fundamentally change." Therefore, there is no such thing that the northern strain is more "poisonous" than the south.

However, some doctors said that clinically, the symptoms after BF.7 infection are indeed generally more severe. Yu Chengbo, chief physician of the Department of Infectious Diseases of the First Affiliated Hospital of Zhejiang University School of Medicine, pointed out that BF.7 and BA.5 symptoms after infection generally have obvious differences, BA.5 clinical manifestations are milder, symptoms are significantly reduced, usually persistent cough, nasal congestion and sore throat and other common symptoms, another symptom is extreme fatigue, and loss of taste and smell has been relatively rare. According to the information released by "Shaanxi Disease Control" and "Nanjing Disease Control" and other places, the main characteristics of the BF.7 variant are: compared with the previous variant, it has strong transmission ability, fast speed, strong concealment, and strong immune escape ability. The main manifestations are high fever, persistent cough, body aches, headache, sore throat, changes in smell, and loss of appetite.

According to the information released by "Nanjing Disease Control", "Henan Disease Control" and "Hengzhou Disease Control", the symptoms after BA.5 infection are mainly manifested as fever, cough, sore throat and other symptoms, and the proportion of asymptomatic infections is high. But no matter which one, prevention is still the same prevention law, and governance is still the same law. (How to use medicine for different symptoms, refer to the article ☞ the day before yesterday After the antigen is positive, don't make 4 mistakes when taking medicine, liver and kidney failure!) There is no ibuprofen, even flower Qingwen, these are just as useful) In short, don't "square"! With vaccines and immunity, most people get through the peak of infection.
