The difference between novel coronavirus pneumonia and influenza is as follows: 1. The novel coronavirus occurs before the Chinese New Year. Usually December – February every year is also the high season of influenza, so the onset of the same time; 2, pathogenic factors are different. New coronavirus pneumonia is caused by the new coronavirus, the systemic manifestations of fever, cough, malaise, there can be some upper respiratory tract symptoms such as sneezing, sneezing, sore throat, there can also be digestive tract diarrhea symptoms, a week later there will be respiratory aggravation of the condition, such as respiratory distress, respiratory distress. If the original underlying disease, there can be difficult to correct respiratory acidosis, coagulation disorders, etc., which can lead to the occurrence of life-threatening; Influenza caused by influenza virus, generally a limited disease, systemic symptoms are more pronounced, fever, body aches, headache, usually after a week can develop into pulmonary infection, but less common; 3, different factors of infection, the new Coronavirus Lung CT can be seen in the lungs of the manifestation of obvious inflammation; Influenza patients Whether lung inflammation exists in the lungs should be judged according to the degree of disease development. In summary, the two have the same onset time, but different etiology and focus. New coronavirus is mainly lung inflammation, with special manifestations on chest radiographs. The main difference between the two is the virus detection, the new coronavirus is a newly emerged virus, so it is more contagious and people do not have immunity. Every year there is influenza, although heavier than the clinical manifestations of the common cold, but it is more familiar with it, there are more mature treatment methods and clinical measures, so it is less fearful, and influenza is not as contagious as the new crown. In fact influenza has a similar mortality rate to the new crown virus. Content source: Dr. Yurai
