The difference and identification of new crown and cold
The new crown and cold have many similar symptoms in the early stage, so it is easy to confuse them, but there are still some obvious differences between the two in terms of symptoms, incubation period, pathogen, imaging manifestations, etc. The specific analysis is as follows:
1. Symptoms: Cold patients are prone to upper respiratory symptoms such as runny nose, sneezing, headache, dry throat, sore throat, and itchy throat, with no fever or only low-grade fever. Patients with new crowns are more likely to have lower respiratory symptoms such as dry cough, fatigue, and dyspnea. Some patients will also have gastrointestinal symptoms such as abdominal pain, vomiting, and diarrhea. The fever is mainly moderate to low-grade fever, and some patients even have no fever. , sepsis, coagulation dysfunction, respiratory distress syndrome, shock, multiple organ dysfunction, etc. may appear rapidly.
2. Incubation period: The incubation period of a cold is generally 1-3 days, which is usually relatively short, while the incubation period of the new crown is relatively long, generally within 14 days, with an average of 7 days.
3. Pathogens: Colds are usually caused by Coxsackie virus, adenovirus, respiratory syncytial virus, and influenza virus, while the new crown is caused by a new type of coronavirus.
4. Imaging manifestations: a cold is an upper respiratory tract infection, and the patient's lungs are usually normal, but most patients with new crowns will have multiple small patchy shadows in the early chest CT, and the extrapulmonary belt is the most obvious, and gradually develop into double lungs Multiple ground-glass shadows and infiltrating shadows.
Although there are certain differences between the new crown and the common cold, some symptoms are relatively similar. Patients may have symptoms such as chills, fever, nasal congestion, runny nose, cough, and sputum. Care must be taken to identify them, mainly relying on throat test nucleic acid testing. If there are related discomfort symptoms, it is recommended to go to the hospital in time for blood routine, new coronavirus nucleic acid test, lung CT examination, etc., so as to clarify the cause and then carry out targeted treatment.
