Teach you how to distinguish between the flu and the new crown is not panic
During the epidemic, whether it is a cold or a new crown, as long as we hear some symptoms such as fever and runny nose, we will always smell it. When you are not sure, your heart will always be full of fear. Whether it is a sick person or a contact person, speaking of these two diseases, there are indeed many similarities, and sometimes it is difficult to distinguish between the two. There is indeed a big difference, and there is no guarantee that you will not be infected with new coronary pneumonia when you are infected with the flu, so you must learn to distinguish between the two diseases.
What is flu:
Influenza is the upper respiratory tract symptoms and systemic symptoms caused by infection with an influenza virus. This is a contagious disease that can spread quickly during epidemics, mainly through breathing and contact. The main symptoms of flu are coughing, high fever, joint pain, general malaise, in severe cases, high fever, difficulty breathing, etc., and eventually death due to complications of multiple organ failure. The incubation period of influenza is 1 to 3 days.
What is new coronary pneumonia:
New coronary pneumonia is a disease mainly caused by lung changes caused by a coronavirus. It is a disease that spreads very rapidly, mainly through droplet transmission and aerosol transmission, and there is the possibility of fecal-oral transmission. The main symptoms of new coronary pneumonia are dry cough without sputum, persistent high fever, nausea, vomiting, and loss of appetite. Severe dyspnea occurs, the clinical diagnosis is positive for nucleic acid, lung imaging changes, and blood oxygen drops. Will eventually die from respiratory failure. The incubation period of new coronary pneumonia is 7 to 14 days.
How to distinguish between influenza and new coronary pneumonia:
1. The incubation period is different: the incubation period of influenza is short and the onset is relatively rapid, ranging from 1 to 3 days, while the incubation period of new coronary pneumonia is long, requiring 7 to 14 days, and individual cases may be longer.
2. Different transmission routes. Both diseases are mainly transmitted through the respiratory tract, but there is another way of transmission of the new crown through close contact. There may also be fecal-oral infection, because the presence of the virus can be detected in the stool of the new crown pneumonia.
3. The symptoms are not exactly the same. The symptoms of the flu are closer to those of a cold. There are symptoms such as coughing, sputum, runny nose, and sneezing, but no difficulty breathing. The main symptom of new coronary pneumonia is cough, but it is dry cough without sputum, and new coronary pneumonia will cause breathing difficulties. .
4. The clinical test results are different. There is no obvious change in lung imaging in clinical testing of influenza, such as pulmonary bacterial inflammation, there will be inflammatory changes. The imaging changes of new coronary pneumonia are obvious, and white lungs will appear. The flu nucleic acid test is negative, the new coronary pneumonia nucleic acid is positive, the flu will not have a rapid decline in blood oxygen, and the new coronary pneumonia blood oxygen will continue to decline.
