Liu Jihai, deputy director of the Emergency Department of Peking Union Medical College Hospital, said that the common cold is a virus that colonizes our normal respiratory tract, so there is no seasonality. Influenza, also called influenza or seasonal cold, is characterized by its contagious nature. In our country, influenza is actually managed as a Class C infectious disease. It can cause infection in a large area of ??the population, and there may be a risk of transmission between people.

The infection caused by the new coronavirus is more transmissible and contagious. Our country is managed according to Class B infectious diseases. Generally speaking, symptoms of the common cold can be relieved quickly for people with no underlying diseases and normal immune function. Influenza symptoms are more severe because it is accompanied by influenza virus infection and may cause more severe systemic symptoms, such as fatigue and body aches. As for new coronavirus infection, in addition to respiratory symptoms, the symptoms of this systemic infection, such as fatigue, body aches, sore throat, including subsequent coughing and sputum production, are relatively more severe than influenza.

The symptoms of influenza and new coronavirus infection are similar, so it is difficult to distinguish and eliminate them without antigens. ...Specifically, influenza and COVID-19 infection are very similar in three aspects: fever, headache and cough, and general fatigue.

1. Whether it is influenza or new coronavirus infection, fever will occur.

Both influenza and COVID-19 infections are accompanied by fever. ...The reason why this happens is because our body is increasing its resistance by generating heat. …From this perspective, influenza and COVID-19 infection are similar. Moreover, among people with mild symptoms of influenza or new coronavirus infection, many people do not have fever, and the symptoms are similar in this regard.

2. Both influenza and COVID-19 infection will produce symptoms of headache and cough.

Whether it is influenza or new coronavirus infection, symptoms such as headache and cough will appear... This is because these two diseases are infected against our respiratory tract, so the symptoms are similar. ...From this perspective, the symptoms of COVID-19 infection and influenza are also similar. Without antigens, it would be more difficult to distinguish the specific situation.

3. When we get the flu and COVID-19, we will all have symptoms of fatigue.

Another similar symptom between influenza and COVID-19 infection is fatigue... This similar symptom occurs because our bodies become very weak after getting sick, and fatigue will naturally occur at this time. symptoms. …In fact, not only COVID-19 infection and influenza, but other illnesses can also cause symptoms such as fatigue in our bodies. … Therefore, if you don’t do antigens and just judge from symptoms, it is difficult to determine whether it is influenza or new coronavirus infection. Therefore, we should still do antigen testing to clarify the cause of the disease so that we can treat it symptomatically.
