How to distinguish between neoconiosis, common cold and influenza?

With the high prevalence of influenza in autumn and winter, the chief of the Infectious Diseases Division has provided answers to the distinction between neoconiosis Rapid antigen self test, the common cold and influenza.

First, the pathogenic point of view. Common cold is caused by some viruses that are fixed, such as rhinovirus; influenza is caused by influenza virus; New crown is New crown virus.

Second, from the point of view of contagiousness. The flu is not contagious, but when the resistance decreases, some viruses that are planted in the upper respiratory tract replicate and cause symptoms. Influenza and neo-crown are both infectious, and neo-crown is significantly more infectious than influenza.

Third, from the point of view of the infection site, the common cold is usually in the upper respiratory tract, usually does not lead to pneumonia, most of the flu is also in the upper respiratory tract, very few, elderly people with underlying disease, may involve the lungs. But the new crown can lead to pneumonia, the new crown virus infection can induce a series of aggravation of the underlying disease, this is a very important feature of the new crown, can not be ignored.

Fourth, in terms of the season of occurrence. The flu is not seasonal, it can happen all year round, because the resistance can be reduced to local viral multiplication leading to symptoms, the flu is mainly in autumn and winter, the new crown virus can happen all year round, but autumn and winter will be the high season, because there are more activities in the house, the air is not circulating. From the clinical point of view, the flu is relatively light, usually with some symptoms of the upper respiratory tract, runny nose, nasal congestion, some individual will have a low fever, rarely a high fever. Influenza often has systemic symptoms, such as headache, fever, sore throat, muscle and joint pains, etc. New coronavirus infection may cause fever, muscle and joint aches, cough, decreased sense of smell and taste, etc. It may also induce aggravation of underlying diseases, especially in the elderly.

Fifth, treatment, the common cold is not treated, itself self-limiting, usually 1-3 days to get well, resistance is good when it passes. Influenza has special drugs, and antiviral treatment can reduce the symptoms and reduce the occurrence of further complications. Antiviral drugs are also available for Xinguang at present, so it is more important to treat Xinguang more aggressively, especially for elderly people with underlying diseases to intervene early to avoid deterioration, including a combination of antiviral treatment, oxygen therapy and Chinese medicine.

Once the fever and other symptoms appear must go to the hospital to screen and check whether it is new crown or influenza, if it is influenza then targeted treatment, new crown is not simply a matter of antiviral treatment early intervention, but also isolation to avoid the risk of further transmission, and also to closely monitor changes in the condition to prevent the development of serious illness, including the risk of aggravation of the underlying disease.
