New coronavirus infection after fever, dry cough, fatigue as the main manifestations, a small number of patients may have nasal congestion, runny nose, sore throat, myalgia and diarrhea symptoms, severe patients in the onset of a week or so will appear respiratory distress, hypoxemia, acute respiratory distress syndrome, multiple organ failure and other related manifestations. Some patients with severe and critical illness may have only low to moderate fever or even no apparent fever during the course of the illness, and some children and newborns may have atypical symptoms such as vomiting, diarrhea, or poor mental health. Mild cases may present with low-grade fever and malaise. The prognosis for the majority of patients is good, but a few patients may be critically ill and require prompt treatment. New coronavirus infection, colds and influenza all belong to the respiratory tract of viral diseases, but they still have a lot of differences, there **** sex, there are also differences.

①Pathogenically. The common cold is caused by a number of viruses that are colonized, such as rhinoviruses; influenza is caused by influenza viruses; and neocollins are neocollins.

②From the point of view of contagiousness. When resistance drops, some viruses colonizing the upper respiratory tract replicate and cause symptoms. Influenza and the new crown are contagious, the new crown is significantly more contagious than influenza.

3 from the point of view of the site of infection. The common cold is usually in the upper respiratory tract, usually does not lead to pneumonia, most of the influenza is also in the upper respiratory tract, very rare, the elderly have basic diseases, may involve the lungs.

④From the point of view of the season of occurrence. Influenza is not seasonal, can occur throughout the year, because of the decline in resistance can appear local viral reproduction leading to symptoms, influenza is mainly fall and winter, the new coronavirus can occur throughout the year, but fall and winter will be the season of high incidence, because of more activities within the household, the air does not circulate. Again, from the clinical manifestations, the cold is relatively light, generally have some symptoms of the upper respiratory tract, runny nose, nasal congestion, individual will have some low fever, rarely have high fever. And influenza often has systemic symptoms, headache, fever, sore throat, muscle and joint pain, etc.. New coronavirus infection can appear fever, muscle and joint pain, cough, smell, taste, etc., may also induce the aggravation of the underlying disease, especially the elderly.

⑤Treatment, the common cold is not treated, self-limiting in itself, usually 1-3 days to get well, resistance is good when the past, we often instruct the patient to drink more water, pay attention to rest on it. There are specific medications for influenza, and antiviral treatment can reduce symptoms and minimize further complications. Antiviral drugs are also available for the new crown, so it is important to be more aggressive in the treatment of the new crown, especially in older people with underlying medical conditions, and to intervene early to avoid worsening of the condition, including a combination of antiviral therapy, oxygen therapy, and traditional Chinese medicine.

In short, under the new crown epidemic, these three diseases are similar, but very different, so we emphasize that once the fever and other symptoms must go to the hospital to see a doctor, screening to check whether it is the new crown or influenza, is influenza, then targeted treatment, is the new crown is not simply antiviral treatment of early intervention, but also isolation, to avoid the risk of further transmission, and at the same time, we must also closely monitor the The disease changes, to prevent the development of serious illness, including the risk of exacerbation of the underlying disease.
